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

For machine production, Shenzhen machining includes transportation and storage of raw materials, preparation for production, manufacturing of blanks, processing and heat treatment of parts, assembly, commissioning, painting and packaging of products. The content of production process is very extensive. Modern enterprises use the principles and methods of system engineering to organize production and guide production. The production process is regarded as a production system with input and output. In the production process, the process of changing the shape, size, location and nature of the production object to make it a finished or semi-finished product is called a process. It is an important part of the production process. The technological process can also be divided into casting, forging, stamping, welding and machining. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines, while other processes are called auxiliary processes, such as transportation, storage, power supply, equipment maintenance, etc. The technological process is composed of one or several sequential processes, and one process is composed of several work steps. Pure machinery includes mechanical design and mechanical manufacturing. Mechanical processing belongs to mechanical manufacturing, which involves manufacturing process. If it is better, mechanical manufacturing technologists are responsible for formulating manufacturing process routes. Some processing that is not suitable or can not be solved by mechanical methods can be completed by bench workers. Such as: scribing, precision machining (such as scraping and scraping sample plates and making molds, etc.), inspection and repair in the process of parts processing. Bench assembly: assembly, component assembly and general assembly of parts according to the assembly technical requirements of mechanical equipment, and make them qualified mechanical equipment after adjustment, inspection and commissioning.

Shenzhen precision parts processing has a good competitive advantage, which is that consumers' praise is relatively high. Usually, when people choose auto parts manufacturers, they will also compare them according to the praise of consumers. With relatively high praise, you can gain great advantages in the competition. Good quality assurance is also an important advantage. Usually, people will choose parts with guaranteed quality to serve the car and ensure the overall performance of the car. For the air filter element, its own quality is relatively light, as long as it can achieve the effect of air purification. The lighter the quality, the better. Therefore, when choosing such auto parts, quality is not necessarily a bad thing! When purchasing auto parts, in order to meet the needs of use, it is necessary to check whether the parts are intact. For some key parts, if there is damage, it is likely to affect the use, and even lead to traffic safety problems in serious cases. So when you buy, you must check whether the product is damaged. The main trend is to be more systematic and modular, because different cars have different parts. Therefore, the requirements for spare parts are also very high. A systematic and modular industrial chain must be formed to meet the needs of different cars.

The production process of Shenzhen mechanical processing refers to the whole process of making products from raw materials (or semi-finished products). For machine production, it includes transportation and storage of raw materials, preparation for production, manufacturing of blanks, processing and heat treatment of parts, assembly and commissioning of products, painting and packaging, etc. The components of bicycles, automobiles, airplanes and other parts we want belong to the category of mechanical processing. Of course, mechanical processing is just the process of realizing products. Precision lathes can be used for turning, milling, planing and grinding precision parts. This kind of machinery is good at turning, milling, planing, grinding and other processing of precision parts. It is the part of the process that is continuously completed under the condition that the processing tools and cutting parameters are unchanged. The preparation of the process route is to formulate the overall layout of the process. The main task is to select the processing method of each surface, determine the processing sequence of each surface, and determine the number of processes in the entire process. The process route must follow certain principles. In this way, the plane can be used to locate the machining hole, ensure the position accuracy of the plane and the hole, and facilitate the machining of the hole on the plane. It is absolutely not allowed to directly contact the workpiece with hands or other objects, so as to avoid damage to the finished surface due to transfer and installation between processes.

The processing functions of commonly used precision parts in Shenzhen are relatively fixed. Vertical machining centers, horizontal machining centers, or machining centers, turning centers, etc. are combined to form a processing system to increase the processing range and capacity of the machine tool. The machine tool is automatically protected according to the load during processing. When the load exceeds the set large load of the machine tool, the machine tool will automatically shut down. The load size can be set and changed by yourself. In the process of processing, the workpiece is detected in real time, and errors are found and corrected in time. This function can effectively avoid the problem of re clamping and positioning caused by unqualified inspection after conventional processing, shorten the production time and improve the production efficiency. In the early stage, the process requirements and batch of precision stamping parts were determined. The function of CNC lathe is to prepare for the early stage. The premise of reasonable selection of CNC lathe is to meet the technological requirements of parts. The process requirements of parts are mainly the structural dimensions, processing range and accuracy requirements of parts. The process flow of precision hardware processing is to order steel materials from the material supplier according to the production needs. After the steel materials are ordered, the materials are opened. After the materials are opened, the tolerance is tested on four sides. Most hardware products are not consumer goods. It is used as supporting products, semi-finished products and tools used in the production process of industrial manufacturing. Only a small number of daily hardware products are the necessary tool consumer goods for people's life. During product processing. The operator shall maintain correct posture and have enough spirit to cope with the work. If he/she finds that he/she is unwell, he/she must leave the post immediately for personal safety and report to the workshop supervisor or a higher level leader.

Shenzhen machinery processing has a wide range of contacts in the industry, matching more types of purchase orders with quotations, and participating in offline procurement and supply docking activities. Only in this way can we have the opportunity to obtain machinery processing orders. Wood anti-corrosion equipment, wood sterilization equipment, wood impregnating tank, wood treatment tank, wood flame retardant equipment, wood modification equipment, wood cooking equipment, wood dyeing equipment; Some sterilization equipment, such as edible fungus sterilization tank, mushroom bag sterilization tank, apricot abalone mushroom sterilization tank, and other equipment and supporting facilities. Vacuum device, pressurizing device, liquid removal tank, mixing device, material truck, biological particle boiler. The selected processing method shall consider that the processing economic precision range of each processing method shall be compatible with the precision requirements and surface roughness requirements of the processing surface. The purpose of heat treatment is different, and the content of heat treatment process and its position in the process are also different. The main feature is to process grooves and linear surfaces. Of course, it can also process cambered surfaces with two or three axes. The CNC system can control the machine tool to automatically select and replace tools according to different processes, automatically set tools, automatically change spindle speed, feed rate, etc., and can continuously complete drilling, boring, milling, reaming, tapping and other processes. It is mainly used for processing complex parts such as plates, discs, molds and small shells. The standard specifies the requirements and inspection methods for geometric accuracy and working accuracy of machining centers. The machining center shall also be inspected in accordance with JB2670-82 General Rules for Accuracy Inspection of Metal Cutting Machines and GB9061-88 General Technical Conditions for Metal Cutting Machines. The dimensional accuracy is a comprehensive assessment of the geometric accuracy and positioning accuracy of the machine tool under certain cutting and processing conditions. It mainly includes boring accuracy, parallel hole spacing accuracy, coaxiality of turning boring, milling peripheral accuracy, arc interpolation milling accuracy, etc. The common lathe is the mother of all machines. You are familiar with the processing technology and metal material properties, which will be helpful for future mechanical design. EDM machine, universal grinder, machining center, laser welding, medium wire walking, fast wire walking, slow wire walking, cylindrical grinder, internal grinder, precision lathe, etc. can be used for turning, milling, planing, grinding and other processing of precision parts.

The whole process of converting raw materials into finished products in Shenzhen Mechanical Processing is called the production process. The production process includes: transportation and storage of raw materials, production preparation, blank manufacturing, machining, heat treatment, assembly, testing, commissioning, painting and packaging. The main part of the production process in the machining workshop (that is, the whole process of using the machining method to make the blank become a qualified part) is called the machining process. The main part of the production process in the assembly workshop (that is, the process of assembling parts into components or complete machines) is called the assembly process. Generally, it is required to know more about CNC machine tools, especially machining centers, and accumulate enough experience to go up the career path. If you plan to engage in mechanical R&D and design in the future, you will be able to access these devices in the learning stage. It is necessary to practice in each workshop in rotation if you want to lay a solid foundation of machinery even after graduation of graduate students, because those who are engaged in mechanical technology or design and research and development should have a deeper understanding of the processing ability of mechanical equipment, and they need to accumulate some knowledge and experience that can not be learned from books. Remember, the machinery industry is made by hands. Tools used in mechanical manufacturing are basically used to cut metal materials, so the term "tool" is generally understood as a metal cutting tool. The main feature is to process grooves and linear surfaces. Of course, two or three axes can also be used to process cambered surfaces; Machining of holes with larger diameter and higher accuracy, and machining of larger workpiece profiles. The cutting performance is comprehensive, which is measured in terms of tool life, cutting resistance, machining surface roughness and chip removal difficulty.

The machining process specification is one of the process documents that specify the machining process and operation methods of parts. It is a process document that, under specific production conditions, writes a more reasonable process and operation method into a process document in the specified form, and is used to guide production after approval. Shenzhen machining process specification generally includes the following contents: process route of workpiece processing, specific contents of each process, equipment and process equipment used, inspection items and methods of workpiece, cutting amount, time quota, etc. In the process of formulating process procedures, it is often necessary to adjust the previously preliminarily determined contents to improve economic benefits. In the process of implementing the process specification, there may be unexpected situations, such as changes in production conditions, introduction of new technologies and processes, application of new materials and advanced equipment, etc., which require timely revision and improvement of the process specification. Machining methods mainly include turning, pliers, milling, planing, inserting, grinding, drilling, boring, punching, sawing, etc. It can also include wire cutting, casting, forging, electric corrosion, powder processing, electroplating, various heat treatment, etc. Car: vertical car and horizontal car; The new equipment is CNC lathe, which mainly processes revolving bodies; Milling: vertical milling and horizontal milling; The new equipment is CNC milling, also called machining center; It is mainly used to process grooves and linear surfaces. Of course, it can also process cambered surfaces with two or three axes; It is mainly used to process the linear surface of the contour, and the surface roughness processed under normal conditions is not as high as that of the milling machine. Commonly used mechanical processing equipment include digital display milling machine, digital display molding grinder, digital display lathe, electric spark machine, universal grinder, machining center, laser welding, medium wire walking, fast wire walking, slow wire walking, cylindrical grinder, internal grinder, precision lathe, etc., which can be used for turning, milling, planing, grinding and other processing of precision parts. Such machinery is good at turning, milling, planing, grinding and other processing of precision parts, and can process various irregular shaped parts, Machining accuracy can reach 2 μ m。 Working procedure is the basic unit of machining process. The so-called process refers to the part of the process that a worker (or a group of workers) completes continuously for the same workpiece (or several workpieces at the same time) on a machine tool (or a work site). The main feature of forming an operation is that the processing object, equipment and operator are not changed, and the contents of the operation are completed continuously.

Shenzhen CNC machining requires higher and higher quality of parts. At the same time, the products are frequently remodeled. In general machining, the proportion of single piece and small and medium batch products is increasing. In order to ensure product quality, improve productivity and reduce costs, it is required that the machine tool not only has good versatility and flexibility, but also has a high degree of automation in the processing process. An efficient and flexible processing electromechanical integration equipment of sensor detection technology, information processing technology, network communication technology, hydraulic pneumatic technology, optical electromechanical technology, etc., is the basis of modern manufacturing technology. Common control media include perforated tape, magnetic tape, magnetic disk and other carriers that can store instruction information. For short NC machining program, it can be directly input into the NC device through the keyboard on the NC operation panel. In addition to general parts such as main drive, feed drive, bed, workbench and auxiliary parts, there are also special parts such as tool magazine for tool storage, automatic tool changer and rotary workbench. Make it an instruction to control the machine tool. After processing the input information, the NC device sends command pulses to the servo system of each coordinate axis of the machine tool, drives the corresponding moving parts of the machine tool, and controls other actions such as speed change, tool change, starting and stopping the machine tool. Automatically process the workpieces that meet the drawing requirements. A numerical control machine tool for multi process machining of workpieces. It has a tool magazine and an automatic tool change device (ATC). After the workpiece is clamped once, the machining center can automatically select and replace tools according to different processes under the control of the CNC system; Automatically change the machine tool spindle speed, feed rate, tool relative motion path and other auxiliary functions. Then record all the contents in the program sheet on the control medium (such as perforated paper tape, magnetic tape, etc.), and then send it to the CNC device to command the CNC machine tool processing. The whole process from analyzing the part drawings to making the control medium required by CNC machine tools is called programming.

Is precision machining a good thing? Aluminum profile extrusion process 1. Check whether the drawings are complete for processing with CNC lathe and precision machining for aluminum parts. 2. Whether the drawing view relationship of the machining center is clear and complete, and whether the dimension units are marked. 3. Quality inspection and assembly relationship, and key dimensions are required for assembly. 4. Difference between old and new layouts. 5. Translation of foreign language pictures. 6.

The officially issued drawings must be stamped with the quality control seal The processing steps of parts processed in the precision machining workshop for aluminum parts processing are: product preliminary test, product processing trial production and product batch production. In the process of product processing and trial production, it is necessary to communicate with customers in a timely manner, and conduct batch production of products after obtaining the evaluation of corresponding processing. Laser cutting technology is an early practical laser technology in laser material processing technology. The laser cutting in the sheet metal workshop generally uses pulse laser, with high energy density and short time, which can process 1 μ The small hole of m is especially suitable for machining small holes with certain angles and thin materials, and also suitable for machining deep small holes and small holes on parts with high strength and hardness or brittle and soft materials. Aluminum processing precision machinery, laser cutting materials include ordinary cold-rolled sheet. Stainless steel, nickel chromium iron alloy and HASTELLOY based alloy. Laser drilling technology is not affected by the mechanical properties of materials, and it is easy to realize automation.

The compound machine tools for CNC machining in Shenzhen have higher requirements for automatic products. The realization of composite fuCNCtions depends on real-time detection and intelligent judgment, data operation, tool management and system control for workpieces and tools. Automation products and technologies such as highly sensitive probes, high-speed processing chips, smaller and faster response sensors and actuators will be more widely used in machine tools. The control information required by the CNC machine tool processing, such as the tool path, the sequeCNCe of various actions, and various auxiliary fuCNCtions (such as soil shaft speed, overfeed speed, tool change, coolant switch, etc.), is stored in the control medium in the digital form of the processing sequeCNCe, and the automatic processing of the machine tool is realized through the CNC device. After startup, let the machine tool idle for more than 15min to make the machine tool reach the balaCNCe state. Set the tool according to the programming origin on the workpiece, and establish the workpiece coordinate system. If more than one tool is used, the length compensation or tool tip position compensation shall be carried out for the remaining tools respectively. We must also develop good working habits and strict working style of civilized production, and have good professional quality, sense of responsibility and spirit of cooperation. The processing scheme for the same part is different, and economic and reasonable process scheme shall be selected according to specific conditions. The ideal processing program should not only ensure that qualified workpieces conforming to the drawings are processed, but also enable the fuCNCtions of the CNC machine tool to be reasonably applied and fully played. CNC machine tool is a kind of high efficieCNCy automation equipment, its efficieCNCy is 2~3 times higher than that of ordinary machine tools. Requirements for machining accuracy and surface roughness, workpiece stiffness, machining allowaCNCe, tool stiffness, durability and status, machine tool type and performaCNCe, etc. The determination of the processing route must first ensure the dimensional accuracy and surface quality of the parts to be machined, and then consider that the numerical calculation is simple, the tool path is as short as possible, and the efficieCNCy is high.
