First determine the diameter of the tool to find the corresponding bit, also need a guide sleeve, a support frame. Clamping abrasive surface should be clean and then process, do not use brute force to avoid affecting the machining accuracy. During the processing of the tool, any abnormal noise should atop the machine, to ensure the service life of the tool.
Before starting the machine, we should check the deep hole machine, whether the bit of the machine is reset, whether the tool has returned to a safe position, whether the machining cutting oil is normal, whether the chip removal device is operating normally, whether data entry is correct. All normal to start the machine
