CNC lathe is a kind of precision mechanical parts processing commonly used, CNC lathe processing materials are usually used for easy cutting steel and copper, easy cutting steel containing sulfur S and phosphorus P higher material, sulfur and manganese in steel is in the form of manganese sulfide, and manganese sulfide in steel plays a role of lubrication, making steel easier to cut, thereby improving the production progress of the lathe. Then what do you need to pay attention to when machining precision mechanical parts?
1、When correcting the workpiece.
Only allowed to use the hand plate to move the chuck or open the lowest speed to find the righting, not allowed to open the high speed to find the righting.
2、Change the spindle rotation direction.
To stop the spindle first, not allowed to suddenly change the direction of rotation.
3、When loading and unloading the chuck.
Only allowed to use the hand to turn the v-belt drive spindle rotation line, absolutely prohibit the direct drive machine to force loosening or tightening. At the same time to pad a board on the bed, to prevent accidents.
4, tool installation.
Should not extend too long, the shim should be level, the width and the width of the bottom surface of the tool consistent.
5, hardware parts processing in.
Not allowed to open the reverse car method to brake the spindle rotation.
6、Rotary type hexagonal lathe.
(1) Not allowed to process bent and rough surface bar material.
(2) When loading material, the material head must be aligned with the chuck hole and gently struck into it, and no messy knocking is allowed.
7、Program-controlled turning lap lathe.
Pre-selection of spindle speed, tool holder feed, tool holder trajectory and continuous overrun according to the requirements of precision hardware parts processing process. Put the electric knob in the position of "adjusting" for test drive, and after confirming that there is no problem, then put the electric rotary in the automatic or semi-automatic position for work.
