General iron products will have rust, this is basic common sense, many people are aware of, then CNC parts processing or accessories when bearings and so on due to inventory conditions or improper rust will be such as prone to rust, and basically not be able to use mechanical methods to deal with, is the use of chemical pickling will damage the accuracy of the parts, then what methods can remove rust? The following I give you a summary of my experience to the method. No damage to the workpiece, no change in the part, no corrosion. High precision parts rework or repair. Due to improper inventory or transportation caused by the surface of the parts generated floating rust, the use of Colin-306 can be very perfect to remove the floating rust, and to ensure the original precision.   I. Soaking cleaning process.   1 the professional cleaning solution into the tank (plastic or stainless steel tank is recommended, so as to reduce the penetration of iron ions into the original solution to reduce the service life).   2 with an electric heater heated to 40-50 degrees and maintain, room temperature can also be just need to extend the time.   3 the hardware processing parts immersed in the tank. Second, wipe cleaning process.   1 repeatedly wipe with a rag Bun, this approach is suitable for large equipment or workpiece cleaning and rust removal.   2 after wiping, blow dry with hot air or natural drying can be coated with anti-rust oil.

The hardware mold processing industry is developing rapidly, and the competitive pressure on enterprises is increasing, whether in processing technology or processing quality are constantly improving and innovating. In this era of fierce competition, enterprises can only ensure good quality, good service and continuous innovation capabilities to meet customer needs and thus win the market, so what do we need to pay attention to when processing precision hardware parts? 1, mechanical work before checking whether the moving part is filled with lubricant, and then start and check the clutch, brake is normal, and the machine will be airborne 1-3 minutes, mechanical failure is strictly prohibited when operating.   2, when working to maintain the correct posture, to have sufficient spirit to cope with the work, such as the discovery of physical discomfort should immediately leave the workplace, and reflect to the leadership. Operation must be focused on the mind, gossip is strictly prohibited, cooperate with each other, the operator must not operate in an irritable, tired state to avoid accidents, to ensure operational safety. All employees check whether their clothing meets the work requirements before entering the workplace. No slippers, high-heeled shoes and clothing that affect safety are allowed, and those with long hair should wear safety caps.   3、When replacing the mold, first turn off the power and stop the operation of the punching machine movement department before starting to install and debug the mold. After installation and adjustment, move the flywheel by hand for two test punches to check whether the upper and lower dies are symmetrical and reasonable, whether the screws are strong and whether the crimp circle is in a reasonable position. 4, must wait for all other personnel to leave the mechanical work area, and take away the debris on the workbench, before starting the power to start the machinery.   5、When the machine is working, it is forbidden to put your hand into the working area of the slider, and it is strictly forbidden to take and put the workpiece by hand. In the punching die to take, put the workpiece must be used to meet the standard tools. If abnormal sound or machine failure is found, the power switch should be turned off immediately for inspection. After the machinery is started, one person should transport and operate the machinery, others should not press the electric construction or step on the foot switch plate, and should not put their hands into the mechanical work area or touch the moving part of the machinery with their hands.   6、At the end of the day, the power supply should be turned off and the finished products, side materials and miscellaneous items on the job should be organized to ensure a clean and safe working environment.

Many precision parts processing enterprises have network promotion or offline marketing activities, the money invested a lot, the traffic has also gained some, but the transaction is not ideal, where is the problem? So, precision parts processing how to improve the conversion rate of inquiry customers? Simply put, to get effective traffic is to make your product, at the right time, the right place, meet the right people. When we can attract the effective traffic, we need to do an action: integrate these external effective traffic, that is, prospective customers.   Through the "internal work", converted into their own customers, is a process from the outside to the inside.   Without a high conversion rate, more traffic is just a sigh of relief.   A simple example: when a customer comes to you to ask the price of cnc precision machining, your price is much higher than the peer situation, your business people should answer how?   If you say the price directly, basically there will be no next step, because: if only look at the price does not look at the value of words, our prices are much higher than peers. The customer who asks the price directly is the customer who asks for the price. At this time, the correct approach is not to say the price but to discuss the needs of the customer. In the face of different precision parts processing customer inquiries, we have to have different response strategies, different words, in order to understand the customer's true ideas and demands, so as to provide different solutions:.   1: Provide a variety of options, avoiding the main issues, with value to prove your products.   2: Filter your target users with easy-to-answer questions.   Not every customer is your target customer, the number of customer service is limited and you need to leave time for your target customers, so you also need to reverse the discourse to determine whether your customers belong to the target customers.   3: Simulate scenarios for corresponding pain point stimulation.   You need to dismantle the user's main needs step by step through the discourse, simulate it again in the customer's situation, meet the customer's pain points and solve his needs. Whatever he asks, you can answer and deliver the value of the product, which is a quality that a business person with a high conversion rate should have.

When choosing a cnc machining manufacturer, we should pay more attention to the quality of the workpiece in addition to the price factor, because a good quality workpiece will be more durable and bring higher benefits. So, how to improve the quality of the workpiece when four-axis cnc machining? 1、Before four-axis cnc machining, it is recommended to use a calibration instrument to check whether the tool is operating within the allowed tolerance. Before machining, you should use the air gun to blow the tool head and locking nozzle clean, or wipe with a cloth to install the knife, otherwise there is a certain impact on the accuracy and quality.   2, four-axis cnc machining workpiece when the program list should be clear as a whole, including the model, name, program name, processing content, tool size, feed, especially the safety length of the tool holder, the margin reserved for each program and the indicator. To be clearly pointed out.   3、The list of CNC machining workpiece should be consistent with the direction of the reference angle indicated by the mold, and then check the upper 3D drawing, especially the workpiece that has been drilled to carry water, you must check whether the 3D drawing and the level on the workpiece are consistent. 4, before processing, must understand the contents of the CNC processing process, the process must be accompanied by 2D or 3D mapping, and must be marked " X length, Y width, Z height " six-sided data, which should be marked flat " Z " value, to facilitate the technical staff in processing After checking whether the data is correct, if there are tolerances, the tolerance data should be indicated.   5, reasonable use of four-axis cnc machining tools, should be careful to distinguish between steel and copper processing, the remaining amount of light knife is reasonable to ensure that the workpiece finish and tool life longer.   6, in the clamping process, please note the name and model of CNC machining workpiece and the program list is the same, whether the material size is matched, the clamping height is high enough, and the number of calipers used.   7、The speed of 4-axis cnc machining needs to be strictly controlled by technical operators, F speed and S spindle speed should be adjusted reasonably. f speed is fast, S spindle should be accelerated. The feed speed must be adjusted in different areas. After processing, check the quality without any problem, then you can finish the four-axis CNC machining process.

cnc machining factory master is how to deal with cnc machining center abnormal current alarm (HCAL red light is lit), the following is the experience and method   Servo unit of 185V AC after rectification into DC 300V, DC side has a detection resistor to detect DC current, if there is a short circuit behind, immediately generate the alarm. If it is always appear, available CNC machining center multimeter to measure whether the main circuit transistor module short-circuit, replace the transistor module by itself, if not short-circuit, interchange the control board with other axes, if transferred with the control board, repair the control board.   If the CNC machining center high-speed alarm and low-speed normal may be the control board or motor problems, which can also be discerned through the exchange of servo units.   Observe whether the alarm is always alarm or occasionally, if it is always alarm is the unit or control board failure, otherwise it may be the motor.   CNC machining center high voltage alarm (HVAL red light is on)   Check whether the three-phase 185V input voltage is normal.   Check the CN2 1, 2, 3 AC +, -18V are normal.   Exchange CNC machining center control board, if the fault is transferred with the control board, it is the board fault. Low voltage alarm? (LVAL red light is lit)   Servo control board detects the main circuit or control circuit voltage is too low, or detects circuit failure.   Check whether the three-phase 185V input voltage of CNC machining center is too low.   Check whether CN2's 1, 2, 3 AC +, -18V are normal.   Check whether the main circuit transistors, diodes, capacitors, etc. are abnormal.   Exchange the control board of the machining center, if the fault is transferred with the control board, then it is a board fault.

The isolation layer solution of hardware CNC is to carry out the solution to the rough surface of hardware CNC, especially in the whole process of hardware CNC machining and deep drawing, and carry out the isolation layer solution with lubricating liquid. Together with this process, it can make the hardware CNC from processing gradually to finish can maintain a high efficiency and smooth processing rate and precision, reduce the waste caused. What are the advantages of large CNC processing plant CNC for isolation layer processing? In the hardware CNC processing plant, the processing CNC machining parts must be lubricated with grease, which is indispensable in the whole process of deep drawing. The application of lubricating oil in the whole process of die casting is to better reduce the friction, enhance the service life of the mold shell, reduce the risk position of the thinning of the deep-drawing parts, and enhance the quality of the surface layer of hardware CNC. Thus, in the whole process of hardware CNC processing, sometimes how to use the isolation layer to solve the CNC gross?   This kind of isolation layer solution is used for the thinning and deep drawing process of CNC. In the thinning and deep drawing, the lubricating fluid is used to reduce friction and cool the mold shell. Dry friction should not be applied. In the whole process of pulling thinning, in addition to the normal application of lubricating fluid, there are some materials must also carry out the isolation layer solution. For example, in pulling cast iron parts, often in the embryo surface layer to carry out copper plating and pickling phosphating, in order to produce an isolation layer in the embryo surface layer and die shell and the middle, in the deep drawing process can store liquid and have self-lubricating characteristics; in pulling stainless steel plate, high-temperature carbon steel and other parts, die shell clamping is more serious, strengthen the compressive strength, and therefore must choose the isolation layer to solve the embryo surface layer.   In the technical professional CNC manufacturers, a clearer understanding of the entire process of CNC processing process, and its clearer grasp of the customer's idealization of the parts required goods, so the selection of manufacturers is a very important stage, can assist customers to reduce costs and delivery of high-quality goods from the source
