When CNC precision parts are machined, the materials we generally choose are steel or copper that are easier to cut. The steel that is easy to cut is usually sulfur steel or steel with high phosphorus content. The sulfur and manganese elements in steel are usually manganese sulfide. In the form, manganese sulfide can make the steel become more lubricated, and then easier to cut, in order to improve its machinability, then what needs to pay attention to CNC precision parts processing?
1. When the workpiece is clamped and set up, you can only use the lowest speed to correct it, or manually pull the chuck to correct it. Absolutely you cannot find it at high speed.
2. If you need to change the direction of rotation of the spindle, you must not suddenly change the direction of rotation, but must first stop the spindle and then proceed.
3, the tool shims on the machine tool should be straight, the width should be the same as the bottom width of the tool, and the tool can not extend too long when installed.
If it is necessary to rotate the brake spindle during CNC precision parts processing, the reverse method must not be used
