CNC lathe processing is a high-precision, high-efficiency automatic machine tool with digital information control parts and tools Mechanical processing method of displacement. It is an effective way to solve the problems of variable varieties, small batches, complex shapes, and high precision of aerospace products and parts, and to achieve high-efficiency and automated processing.

1. Conscientiously implement the relevant provisions of the "General Operating Regulations for Metal Cutting Machine Tools".

Two, earnestly implement the following general regulations concerning lathes:

(1) When aligning the workpiece, only use the hand to move the chuck or turn on the lowest speed for alignment, not high-speed alignment.　　

(2) When changing the rotation direction of the spindle, stop the spindle first, and do not change the rotation direction suddenly.　　

(3). When loading and unloading the chuck, only turn the V-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, block wooden boards on the bed surface to prevent accidents.　　

(4). The tool should not be installed too long. The gasket should be flat and the width should be the same as the width of the bottom of the tool.　　

(5). It is forbidden to drive the reverse rotation to brake the spindle rotation during work.　　

3. Conscientiously implement the following special regulations concerning some special lathes: 　　

(一), the wheel type hexagonal lathe: 　　
​
1. It is not allowed to process bars with curved and rough surfaces.　　

2. When loading the material, the material head must be aligned with the chuck hole, and lightly punched in, not disturbing and knocking.　　

(2) Program-controlled transfer lathe: 　　

According to the process requirements, pre-select items such as the spindle speed, the feed of the tool post, the trajectory of the tool post and the continuous offside of the work step program. Put the electric knob in the "adjustment" position for test run. After confirming that there is no problem, put the electric knob in the automatic or semi-automatic position to work.
