Confirm the model, size and allowance of processing blank according to the program sheet before operation, and sand and grind the blank
After operation, confirm the position of the workpiece and the processing sequence, and complete the table comparison
In the process of centring, if it is necessary to “split the rod”, the rotating speed is 501r / m. if the tool is used to divide the center, the speed depends on the tool. In this process, it should be noted that the data must be taken at the same height to ensure the accuracy of the split. After the separation, the “g0g54 x0y0” can be used for inspection
Before the formal processing, check and confirm whether the position of the workpiece is placed and whether the fetching is correct
C. Precautions in CNC machining
Check whether the tool is consistent with the machining procedure
- When installing the tool, confirm whether the length of the tool and the selected tool holder are suitable
- In the same workpiece, each tool setting should be kept in the same area to ensure the accuracy of tool connection
In the program, use the gas blowing knife as much as possible
- Clean the aluminum slag in the machine tool before the smooth knife oil injection to prevent the aluminum slag from absorbing oil
- 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
- If too much machining allowance is found during machining,
You 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 on their own
