CNC lathe is usually used in processing materials. The materials processed by lathe are free cutting steel and copper. Free cutting steel has high sulfur s and adjacent P content. Sulfur and manganese exist in the form of manganese sulfide in steel. CNC precision parts processing plays a lubricating role, making steel easier to cut, so as to improve the production progress of lathe production. <br>
So what should be paid attention to when CNC lathe is machining? < br > what should be paid attention to when CNC lathe is machining
1、 Conscientiously implement the relevant provisions of the general operating procedures for metal cutting machine tools. <br>
2、 Seriously implement the following general regulations on lathes: < br > 1
1. When aligning the workpiece, only use the hand to move the chuck or open the lowest speed for alignment, and do not open the high speed for alignment. <br>
2. When changing the rotation direction of the spindle, stop the spindle first, and do not change the rotation direction suddenly. <br>
3. When loading and unloading the chuck, it is only allowed to turn the V-belt by hand to drive the spindle to rotate. It is forbidden to directly start the machine tool to force loosening or tightening when machining CNC precision parts. At the same time, a board should be padded on the bed surface to prevent accidents. <br>
4. The tool installation should not extend too long, the gasket should be flat, and the width should be consistent with the width of the tool bottom. <br>
5. It is not allowed to drive the reverse car to brake the spindle rotation. <br>
3、 The following special regulations on some special lathes should be carried out carefully: < br > 1
（1） Return type hexagonal lathe: < br > 1
1. It is not allowed to process bent bar with rough surface. 2. When loading, the material head must be aligned with the chuck hole, and it is not allowed to knock randomly. <br>
（2） Program controlled transfer lathe: < br > 1
According to the process requirements, the pre selection of some items, such as the spindle speed, CNC precision parts processing feed, tool rest trajectory and continuous offside, is carried out.
