China Shenzhen Perfect Precision Product Co., Ltd. company news

Precision parts machining needs to produce high quality and stable products. First, employees must have extensive machining experience and excellent skills. Machining must be performed using superior technology. As we all know, machining is equally delicate work. Testing the production process is very difficult. Even if it can be done well, it takes a long time. If it does not start well at the beginning, it is easy to give up. Secondly, the excellence of the machining process determines whether the product is of high quality or not. It is also an indispensable reference point when we use it to set company rules and regulations. Production and management necessarily require a perfect process, a process that is at the service of a perfect product.   Third, we must pay attention to communication during the production process. Whether it is nodal time or there are problems, we must improve communication. Communication between the processing plant and the equipment manufacturer is essential to the processing of automated equipment components. Processors often process attachments based on attached drawings, but more commonly, many processing spaces can be simplified and improved, which can reduce costs and increase efficiency. There are many items in our daily life that use mechanical products. The name of machinery (English name:machinery) is a generic name for machines and mechanisms. A machine is a tool that helps people work less difficult or with less work. Items such as chopsticks, brooms and scorpions can be called machines. They are simple machines. Complex machines are made up of two or more simple machines. These more complex machines are often referred to as machines. From the point of view of structure and motion, there is no difference between a mechanism and a machine, which is usually referred to as a machine. Spare parts, the inseparable individual parts that make up the machinery and the machine, are manufactured usually without an assembly process. The quality of machined machine parts requires special attention, and the quality of the product is the key to the decision.

Precision forging and forming technology refers to the part forming technology that can be used with little or no processing after the basic forming of the part, also known as near-net forming technology. This technology is developed based on conventional forging and forming technology, and is an application technology integrated by computer information technology, new energy, new materials, etc. At the present stage, precision forging and forming technology is mainly used in precision forging parts and refining blanks, etc. Precision forging and forming technology, it has obvious advantages, low cost, high efficiency, energy saving and environmental protection, high precision. There are many types of this forming process, according to the forming speed: high-speed precision forging, general precision forging, slow speed precision forging forming, etc.; to forging process metal flow condition as the standard classification: semi-closed, closed, open precision forging forming process; according to the forming temperature: super plastic, room temperature, medium temperature, high temperature precision forging forming, etc.; according to the forming technology is divided into: shunt forging, isothermal forging, compound forging, warm precision forging forming, hot Precision forging forming and cold precision forging forming, etc. According to the forming technology of fine forging technology, has become the production of people are accustomed to the classification of the way. 1. Double-action forging This process is one of the more advanced fine forging technologies. This technology is through a punch in the closed groove inside the one-way extrusion or two punch two-way reactive extrusion and make the metal once formed, the formed parts belong to the near net forgings without flying edge. The reason for using plug forging is to increase the material utilization rate and reduce the complexity of the machining process. Closed forging is capable of forming complex shapes and achieving large deformations in a single operation, eliminating the need for most cutting in the production of complex parts and effectively reducing costs. 2. Isothermal Forging Isothermal forging refers to the process of forging and processing of the blanks in a die at a constant temperature to form a fine forged part. Compared with conventional forging, isothermal forging can control the heating temperature of the blank within a certain range, so that the temperature during the forging process is approximately equal, which greatly improves the plastic change of the die due to sudden temperature change during the process. Due to the characteristics of isothermal forging process, it is especially suitable for fine forging of materials that are sensitive to deformation temperature or difficult to form, such as magnesium alloy, aluminum alloy, etc. 3. Shunt forging The important part of the diverging forging technology is to establish a material diverging channel in the forming part of the die or blank to ensure a good filling effect. With this technique, as the cavity is filled with material, a portion of the material is left in the diversion channel, creating a diversion that helps to fill the hard to form parts. The advantages of split-flow forging are the ability to avoid closures, good forming results when forming gears, the ability to achieve the required accuracy, the lack of post-forming reworking, and the long die life. 4. Isothermal forging Isothermal forging refers to the process of forging and processing of blanks in a die at a constant temperature to form a fine forged part. Compared with conventional forging, isothermal forging can control the heating temperature of the blank within a certain range, so that the temperature during the forging process is approximately equal, which greatly improves the plastic change of the die due to sudden temperature change during the process. Due to the characteristics of isothermal forging process, it is especially suitable for the fine forging of materials sensitive to deformation temperature or difficult to form materials, such as magnesium alloy, aluminum alloy, etc. 5. Cold forging forming In the case of forging metal materials without heating, called cold forging, there are two main cold upsetting and cold extrusion technology. Compared with other processes, its advantage is that the shape of the workpiece is easy to grasp, there will be no deformation due to high temperature, the disadvantage is that the impedance in the deformation process, the workpiece plasticity is poor. 6. Composite fine forging forming Composite fine forging forming process refers to the technology of integrating multiple forging methods, or combining other material forming technologies and forging processes. The traditional process of processing materials and parts has great limitations, and the composite process developed on the basis of the traditional process can not only enhance the strengths and avoid the weaknesses, combined with the strengths of each, but also in the scope of the processing object has been extended. 7. Hot finishing forging forming Hot finishing forging is a precision forging technology that finds a suitable temperature above the recrystallization temperature as the processing temperature. However, compared with the warm finish forging technology, it will occur violent oxidation due to the higher temperature selected, resulting in poor surface quality and insufficient accuracy of forgings. 8. Warm finishing forging forming Warm finishing forging technology is a precision forging technology to find a suitable temperature below the recrystallization temperature as the processing temperature. When choosing the temperature, it is better to choose the time when the plastic deformation of the metal is better, and before the strong oxidation occurs.

Precision hardware processing, indicating that the processing is all hardware to more, and these hardware products in some application equipment, or application accessories will be more, but then, in the process many people will ignore, we will now understand it! Casting properties: refers to whether the metal or alloy is suitable for casting some process properties, mainly including flow properties, the ability to fill the casting mold; shrinkage, the ability of volume shrinkage when the casting solidifies; deviation refers to chemical composition unevenness. Welding performance: refers to the metal material by heating or heating and pressurized welding method, two or more metal materials welded together, the interface can meet the characteristics of the purpose of use. Top gas section performance: refers to the performance of the metal material can be granted top forging without rupture. Cold bending performance: refers to the metal material at room temperature can withstand bending without rupture performance. Bending degree is generally used to bend the angle α (outer angle) or bending center diameter d to the material thickness a ratio, a the greater or d / a smaller, the better the cold bending of the material. Stamping performance: the ability of metal materials to withstand stamping deformation processing without rupture. Stamping at room temperature is called cold stamping. The test method is to test by cupping test. Forging performance: the ability of the metal material to withstand plastic deformation without rupture during forging processing. Precision hardware parts processing cooperation between enterprises will be more intensified, in order to get better help competitive position and improve competitiveness, decomposition will be further intensified, this kind of high-speed shock brought about by the direct camp in the north-south pole decomposition trend expansion, sales channels between the competition is also more intense day by day, quality pressure increases, because of the domestic hardware processing kitchen products oversupply, sales channels become one of the key competitive factors The parties to the fight for the channel day by day towards fierce, market competition will turn to high-quality, high-tech products, precision hardware parts processing in all stages of space are compressed, more and more companies recognize that precision hardware parts processing this industry is the direction of long-term development, and thus strive to explore new development path.

Metal parts, mold processing, steel processing, CNC processing, precision machining, from these years time, the application range is more and more extensive, the effect is also better than in previous years, mainly with the assistance of machinery and equipment, natural in the workmanship, quality can also be better, many industries in the development, if there is no machinery and equipment processing, efficiency, or the speed of workmanship and other manufacturers to compare the advantages of obvious. The pursuit of high precision in the precision parts processing industry is a continuous progress, the manufacturing capacity of automated equipment will be able to improve the innovation of higher value for customers, parts machining industry is very important. The enterprise's products will be favored by the market, the quality and precision of the product is the focus of customer concern. Customers choose you, will not be familiar with each other because of the relationship with you, it must be precision parts machining can meet the needs, can improve the performance of its equipment, improve the quality of production products, to create more profits. In the actual production and processing, we will always be the more to a variety of problems in the processing of equipment will also produce some technical problems, so that the precision parts processing errors are getting bigger and bigger, what exactly is the reason for this?   Parts processing equipment dynamic tracking error is too large and alarm, you can check whether its servo motor speed is too high; position detection components are good; position feedback cable connector is good contact; the corresponding analog output latch, gain potentiometer is good; the corresponding servo drive is normal, etc., and timely maintenance. Of course, if the CNC machine tool movement overshoot will also cause parts processing accuracy is not good, for example, is too short acceleration and deceleration time, can be appropriate to extend the speed change time; may also be a servo motor reducer and screw between the connection is loose or rigid too poor, can be appropriate to reduce the position of the ring gain. It is worth noting that when the two-axis linkage of the parts processing equipment, the axial deformation of the circle and oblique elliptical error and other factors under the influence of the parts processing accuracy will also become poor. The deformation may be caused by the machinery is not well adjusted; while the oblique ellipse error needs to check the position deviation value of each axis first, if the deviation is too large, the position ring gain can be adjusted to exclude.   Various factors may cause changes in the machining accuracy of precision parts, requiring our technical staff to master more professional knowledge, machining enterprises rely on a high degree of talent, enterprises should continue to introduce new equipment at the same time, but also to train a variety of talents, so that the precision of the enterprise's products to keep up with the needs of the times.

Precision parts processing requires precision, precision, from processing to the completion of the process of workmanship is not a problem, applied in aerospace technology, or other metal equipment, machinery and equipment, the quality of the problem is certain to get protection, the protection of the product, the manufacturer's reputation, or workmanship and other aspects have a certain impact on the la, so that precision parts processing can not be missing. (1) rough turning: first use the cross slot turning tool to rough the shape of the two ends of the part because of the cross slot turning tool cutting process resistance is small, easy to break the chip, so the use of the cross slot tool on the two ends of the shape of the rough turning effect is better. However, because the titanium alloy material is very easy to heat deformation in the processing, so in the cutting process must use cutting fluid for adequate cooling. (2) Semi-finish turning: after the part is thoroughly cooled, then use the external offset tool to turn out the reference outer circle of the part, hold the part shape by soft jaws, use the micron lever table to correct the part shape, and perform precision machining on one end of the part, which cannot be machined in place at one time. (3) Precision turning: after the part profile margin is removed, the part is drilled and bored to ensure the size and accuracy requirements. Correct the part shape again to ensure the dimensional accuracy within 0.003mm, and leave a margin of 0.05mm for the finish turning shape. because the double top takes the inner hole at both ends as the positioning reference, and the shape margin before the final finish turning of the part is small, so the drilling and boring and the finish turning shape are completed in one clamping and correction, and the bore is chamfered well to prepare for the next double top process. Precision mechanical parts are made of titanium alloy material, the part shape and hole size processing accuracy requirements are very high, requiring surface roughness under normal circumstances need to be precision machined on the grinder, so as to achieve the requirements of the drawing, so that to achieve the drawings provided by the customer's surface roughness and tolerances and other data. Professional staff is very important, good staff on this aspect of workmanship to achieve a rate of up to about ninety percent.

Accuracy is very important for parts processing, because it affects the final results of the problem, so want to make the final product effect is good, then we have to ensure that the accuracy is always correct. If the accuracy has changed, then we must correct it in time, but because there is more than one factor affecting the accuracy, before solving the problem must know what is the cause of the impact on the accuracy, the following we will understand what causes the parts machining accuracy deterioration is? First, the parts themselves are poorly machined, generally speaking, if the dynamic error between the shafts is not well adjusted at the time of installation, or because the shaft drive chain changes due to wear will affect the accuracy of the parts. Generally speaking, this type of error caused by the accuracy of the chapter can be re-adjusted compensation amount to solve. And if the error is too large or even if the alarm is generated, it is necessary to check the servo motor, observe whether its speed is too high. Second, the machine tool in operation overshoot will also affect the processing accuracy, possibly because the acceleration and deceleration time is too short, the appropriate extension of the change time, of course, is also very likely because the link between the screw and servo motor loosening. Third, because of the two-axis linkage generated by the roundness of the overshoot, the machinery is not adjusted to form a circle of axial deformation, the axis of the screw gap compensation is not correct or shaft positioning offset, may have an impact on the accuracy of precision parts. These points are the reasons that lead to poor machining accuracy of the parts, now the more precision parts on the higher the requirements of precision, so we must pay attention to this aspect of the problem, so today we will first talk about it!  

In the machining industry, generally the most common processing methods are turning processing and milling parts, so when choosing, many people will be because of these two to choose to their own, but here to remind everyone, when we are choosing certainly distinguish the difference between the two, what are the advantages of the two, which one is more suitable for you. Here we will understand the difference between rough cutting and fine cutting in what? After rough cutting, the entire workpiece is actually very close to the appearance and size required by the workpiece itself, but at this time there is still a small margin on the surface of the workpiece for finishing cutting, and the surface of the workpiece after finishing cutting will be more polished and the size will be more accurate. Usually, the workpiece can achieve the required appearance and size after one rough cut and one finish cut. However, not all workpieces require only one cut, and some parts of the workpiece may require multiple rough cuts. At the same time, there are some workpieces that do not require too much precision or have very small cutting volume, and may only need to go through one finishing cut to achieve the requirements of the workpiece. Rough cutting because the workpiece needs to cut a large margin, so it needs to have a greater cutting force than fine cutting, which requires the machine, tool, workpiece can meet the three, and rough cutting is possible to quickly remove the margin, and the effect of the surface properties can not be too rough. Fine cutting is the surface performance of the workpiece, and dimensional accuracy to meet the requirements of the workpiece, so fine cutting requires the use of tools also need to be very sharp, because the cutting volume is small, so the measurement of precision requirements are very high. Today we will first talk about it!

As long as from the name above, we know that he is different from the ordinary parts processing, this process is generally necessary to choose. So we must understand clearly what kind of processing method this is before choosing this processing method, to understand clearly what his advantages and disadvantages are, then we will understand the following non-standard parts processing in the end is what kind of processing method? First of all, we know that non-standard parts are proposed relative to standard parts, so before understanding non-standard parts we need to know what is meant by standard parts. Standard parts refer to the structure, size, drawing, marking and other aspects have been completely standardized, and the common parts produced by professional factories, like threaded parts, rolling bearings, etc.. In a broad sense, it includes standardized fasteners, links, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. Narrow sense only includes standardized fasteners. Domestic commonly known as standard parts is the abbreviation of standard fasteners, is a narrow concept, but can not exclude the existence of the broad concept. In addition, there are industry standard parts, such as automotive standard parts, mold standard parts, etc., also belong to the broad sense of standard parts. Non-standard parts processing professionals to elaborate is mainly the state did not set out strict standard specifications, no relevant parameters outside the provisions, by the enterprise free control of other accessories. There are many varieties of non-standard parts, and there is no very standard classification. Roughly classified as follows. Metal non-standard parts: The customer provides the drawing, and the manufacturer uses the equipment to make the corresponding product according to the drawing, usually the mold is mostly, tolerance requirements, finish are specified by the customer, there is no certain paradigm. Products from casting to finishing completely need the corresponding quality control, the process is complex and variable, and the general cost is higher than standard parts. Non-metallic non-standard parts. It is the processing of some non-metallic materials. Such as plastic, wood, stone, etc. In recent years, the injection molding industry, the development of plastic molds increasingly sophisticated, surface design, programming CNC references, so that the cost of non-standard processing and tolerance levels have been greatly improved.

Requirements are every job has, because it will directly affect the quality of the products produced, so in order to ensure the quality of the product, we do not only have to have requirements for the equipment, but also for the operator, and some processing materials, which are to have certain standards, only these reach the standard, then the production of the product can be our ideal look, so the following we will understand what are the requirements of the material for precision parts processing? In the process of parts processing production and manufacturing, because the production requirements and conditions of various parts are different, their manufacturing process solutions are also different. When the same parts are produced by different process solutions, their production efficiency and economic efficiency are also different. Precision machining is not what materials can be precision machined, some materials are too hard, more than the hardness of the machined parts, it is possible to crash the machine, so these materials are not suitable for precision machining, unless it is a special material made of machine parts, or laser cutting. For processing materials are divided into two categories, metallic materials and non-metallic materials. For metal materials, the hardness is the largest for stainless steel, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. is the processing of non-metallic materials. Requirements for material hardness, for some occasions, the material is the higher the hardness the better, but only limited to the hardness requirements of the processing machine, the processing material can not be too hard, if the machine is harder than the hardness is not processed. Material soft and hard moderate, at least one grade lower than the hardness of the machine, but also depends on the role of the processed device is to do what with the machine parts reasonable selection of materials. These are the requirements of precision parts processing materials, in fact, these requirements are also very simple, we just need to be careful and cautious when making a little, these are very easy to do, so today we will first talk about here!

How to highlight the advantages of five axis CNC machining for small batch parts In the cnc processing industry, the cnc processing of batch parts can show processing advantages, one of which is efficiency. Because cnc machining batch parts first needs to save time, efficiency can reduce many costs, the important thing is to save time. Generally, the efficiency of cnc machining batch parts with three-axis machine tool is relatively low. First, clamp several times. If the part has four sides, the whole workpiece needs to be machined with six sides and clamped six times. 5-axis CNC machining Regardless of the processing efficiency, clamping takes a lot of time, and the allocation of multi face processing requires more machines. If the side that is not easy to process is encountered, the fixture needs to be made to cooperate with the processing, which is not ideal in terms of cost and efficiency. However, five axis linkage machining has improved many problems. First, efficiency. Five axis CNC machining and clamping do not require so much effort. It only needs one clamping to complete the processing of multiple surfaces, which improves the efficiency, reduces the pressure of CNC on-site clamping, and also reduces a lot of time costs for fixture matching processing. Generally, a three-axis machine tool needs six times of clamping to complete the processing of the workpiece. Basically, a five axis machine tool can complete the processing of the whole workpiece only by clamping it twice. Therefore, the efficiency of 5-axis cnc machining has a great advantage, followed by quality. On the premise of ensuring efficiency, the quality of batch parts must be guaranteed first. In case of quality problems, the whole batch of workpieces will be repaired And even scrapped in batches. Therefore, before improving efficiency, we must first ensure good quality. Due to the large number of clamping times, there will be some errors when machining the side faces of multi sided batch parts with three-axis machine, such as improper connection or processing failure, and sometimes it needs to be arranged outside to complete the processing. On the one hand, it has nothing to do with the cost increase, but there will be some defects in quality. However, in five axis cnc machining, some complex sides can provide cutting environment for the tool according to the change of workpiece angle. Since the workpiece does not need to be disassembled for calibration, the error when machining the side surface is greatly reduced.
