After the machinists select a certain processing method, the CAD / CAM system can automatically output CNC code, such as computer gong processing, mechanical parts processing, CNC machine tool processing, Dongguan high-speed computer gong processing, which usually refers to G code, and input the code into the controller of CNC machine tool for actual processing operation. The process specification of large-scale computer gongs is one of the process documents which stipulate the machining process and operation method of parts. Under the specific production conditions, the more reasonable technological process and operation method are written into process documents according to the prescribed form, which are used to guide the production after being approved. Machining process specification generally includes the following contents: process route of workpiece processing, specific content of each process and equipment and process equipment used, inspection items and inspection methods of workpiece, cutting amount, time quota, etc. Large computer gongs processing technology is based on the process, changing the shape, size, relative position and nature of the production object to make it a finished product or semi-finished product. It is a detailed description of each process. For example, as mentioned above, rough machining may include blank manufacturing, grinding, etc., and finishing may be divided into turning, fitter, milling machine, etc., and each step is just like this There must be detailed data, such as how much roughness and tolerance should be achieved. The importance of high speed CNC motorized spindle
1. High speed CNC must first check the parameters of the input starting point, and it is strictly forbidden to knock or impact the rotor end of the spindle motor during operation. The operator is required to pay attention to the starting point of z-axis during tool setting to prevent misoperation. It is necessary to avoid the damage to the bearing of spindle motor caused by collision and knife binding during operation. Once there is knife binding phenomenon, stop the machine immediately, so as to prevent the bearing from being damaged by high-speed operation. Then, start running in from low speed, the time is slightly longer than normal running in time, until the motor runs smoothly and normally.
2. High speed CNC should ensure that the motor cooling circulation system of engraving and milling machine works normally before starting up and using. Computer gong processing, mechanical parts processing, CNC machine tool processing, Dongguan high speed computer gong processing, and then turn on the spindle motor. It is strictly prohibited to use the spindle motor without cooling. The working environment temperature should not be higher than 30 ℃. When the ambient temperature is higher than 30 ℃, air conditioner or refrigerator should be used for forced cooling of spindle motor.
3. According to the principle of running from low speed to high speed, the spindle motor should be preheated step by step. When the motor reaches the required speed, the no-load operation is stable, and the temperature is cooled, then the processing can be carried out. Only in this way can the better machining accuracy be ensured.
4. When planning the tool path, it is necessary to ensure that the force of the spindle motor is reasonable, and the engraving process should be carried out according to the cutter principle provided by the technical service personnel. It is necessary to prevent the vertical cutting tool and prohibit the spindle motor from overload operation, so as to ensure the normal service life of the spindle motor.
5. Generally, the spindle motor should be disassembled, cleaned and reassembled for use after running for about one year, so as to ensure the bearing accuracy and prolong the service life. In order to ensure that the spindle motor can work normally and well, the assembly and assembly must be carried out by experienced professional operators, such as computer gong processing, mechanical parts processing, CNC machine tool processing, Dongguan high-speed computer gong processing, clean environment, and the use of appropriate tools. Do not knock at random. For the temporarily unused motorized spindle, the residual water in the water chamber shall be blown out with compressed air, and the sleeve and shaft head shaft hole shall be oiled for rust prevention and placed in a cool and dry place.
6. The water quality of high-speed CNC must be clean, and the cooling water of spindle motor should be pure water. In order to prevent the occurrence of microorganisms and scale, the water should be changed every seven days under normal conditions. When the surrounding environment is higher than 30 ℃ and there is no forced refrigeration measures, the purified water should be replaced once a day at the highest water temperature. In addition, the operator should form the habit of observing the water temperature in the work.
