Conscientiously implement the relevant provisions of the General Operating Procedures for Metal Cutting Machine Tools.
Carefully implement the following general regulations for lathes:
1. For workpiece alignment, only the hand plate can be used to move the chuck or the lowest speed can be used for alignment. High-speed alignment is not allowed.
2. When changing the rotation direction of the spindle, stop the spindle first, and do not suddenly change the rotation direction.
3. When loading and unloading the chuck, it is only allowed to rotate the triangle belt by hand to drive the spindle to rotate. It is absolutely forbidden to directly drive the machine tool to loosen or tighten it. At the same time, planks should be placed on the bed to prevent accidents.
4, the tool installation should not be too long, the gasket should be flat, the width should be consistent with the width of the bottom surface of the tool.
5. The reverse brake spindle is not allowed to rotate when working.
Carefully implement the following special regulations for some special lathes:
(1) Return wheel type hexagon lathe:
It is not allowed to process curved and rough surface bars.
When loading, the material head must be aligned with the chuck hole, gently drive in, not allowed to knock.
(2) program-controlled multi-station lathe:
according to the process requirements, pre-selection step program spindle speed, tool rest feed speed, tool rest movement track and continuous offside and other items. Put the electric knob in the "adjustment" position for trial operation. After confirming that there is no problem, put the electric knob in the automatic or semi-automatic position to start working.
