1. Confirm the model, size and machining allowance of the blank according to the program sheet before operation, and sand and grind the blank
2. Confirm the position of the workpiece, computer gong processing, Dongguan computer gong processing, Shenzhen computer gong processing, mechanical parts processing, Guangzhou computer gong processing and the processing sequence to complete the table comparison
3. If it is necessary to “divide the middle rod”, the rotating speed is 501r / m. if the tool is used to divide the center, the speed depends on the tool, such as computer gong processing, Dongguan high speed computer gong processing, Dongguan mold processing, Dongguan Mechanical parts processing, CNC processing. In this process, it should also be noted that the data must be taken at the same height to ensure the accuracy of the separation. After the separation, the “G0 g54 x0 Y0” can be used for inspection
4. Before formal processing, check and confirm whether the position of the workpiece is placed and whether the fetching is correct
C. Precautions in CNC machining
1. Before machining in each program, it is necessary to strictly confirm whether the tool is consistent with the program
2. When installing the tool, confirm whether the length of the tool and the selected tool holder are suitable
3. In the same workpiece, each tool setting should be kept in the same area to ensure the accuracy of tool connection
4. Air blowing should be used as much as possible in roughening procedure, computer gong processing, Dongguan computer gong processing, Shenzhen computer gong processing, mechanical parts processing, Guangzhou computer gong processing, and oil injection in the light knife program
5. Clean the aluminum slag in the machine tool before the smooth knife oil injection to prevent the aluminum slag from absorbing oil
6. During the operation of the machine tool, the operator shall not leave the machine tool or regularly check the operation status of the machine tool. If it is necessary to leave midway, relevant personnel must be designated to check
7. If too much machining allowance is found in the process of processing, computer gong processing, Dongguan high-speed computer gong processing, Dongguan mold processing, Dongguan Mechanical parts processing, CNC processing must use “single section” or “pause” to clear x, y, Z values, and then manually mill them off, and then swing back to “zero” to let them run by themselves
8. In case of tool collision during CNC processing, the operator must stop the machine immediately, such as pressing the “emergency stop” button or “reset key” button or setting the “feed rate” to zero
