First, the serious implementation of the "metal cutting machine tools, general operating procedures," the relevant provisions.

Two, the following relevant provisions of the general provisions of the lathe:
1, looking for the workpiece, only by hand chuck or the low speed is looking to drive high speed alignment.
2, change the direction of rotation of the spindle, to stop the spindle after the first, do not suddenly change the direction of rotation.

3, loading and unloading chuck, only used in military rotational triangle belt driven spindle out, the absolute prohibition of direct starting the machine forced loosening or tightening. At the same time, the bed mat board, to prevent the occurrence of accidents.

4, the tool installation should not be stretched too long, gasket to smooth, width and tool width of bottom line.

5, the work is not allowed to open the anti car method to brake spindle rotation.

Three, seriously implement the following relevant part of the special provisions of the special lathe:
(a), wheel type six angle lathe:

1, are not allowed to process bending, rough surface of the rod.

2, charging should be material on the chuck hole, gently shot, prohibit disorderly upset knock.
(two), programmed rotary lathe:

Preselection of about industry and step program spindle speed, tool feed rate, tool trajectory and continuous offside project according to the process requirements. Put the electric knob in the "adjustment" position to run the test, confirm the no problem, then put the electric spin in automatic or semi-automatic position to work.
