CNC precision parts processing we generally choose the material is easier to cut steel or copper, easy to cut steel is generally sulfur content or phosphorus content is relatively high steel, sulfur and manganese elements in steel is usually in the form of manganese sulfide, manganese sulfide can make the steel become more lubricious, and then easier to cut to improve its machinability, then CNC precision parts processing need to pay attention to What is it?
1, in the workpiece clamping correction, can only use the lowest speed state for correction, or manually trigger the chuck for correction, absolutely not in the high-speed state correction.
2、If you need to change the rotation direction of the spindle, you must not suddenly change the rotation direction, but stop the spindle first and then carry out.
3, the machine tool spacer should be flat, the width should be the same as the width of the bottom surface of the tool, and the tool should not extend too long when installed.
4, in CNC precision parts machining if necessary to brake the spindle rotation, must not use the method of reversing.
