Jiangsu Dongfei Precision Co., Ltd. is a high precision, high efficiency automatic machine tool with digital information control parts and tool displacement machining method. It is an effective way to solve the problems of variable varieties, small batch size, complex shape and high precision of aerospace parts and realize high efficiency and automatic processing.
Conscientiously implement the relevant provisions of "General Operation Rules for Metal Cutting Machine Tools".
Ii. Earnestly implement the following general provisions on lathes:
(1) alignment of the workpiece, Shanghai CNC machining is only allowed to use hand plate moving chuck or open low speed alignment, not allowed to open 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 chucks, it is only allowed to turn the triangle belt by hand to drive the spindle to turn around, and it is forbidden to directly start the machine and force to loosen or tighten it. Want to be on bed surface at the same time pad piece board, prevent to produce accident.
(4), the tool installation should not extend too long, the gasket should be flat, the width and the width of the tool bottom.
(5) It is not allowed to brake the spindle rotation by driving backwards during work.
Iii. Conscientiously implement the following special provisions concerning some special lathes:
(A), return wheel type hexagonal lathe:
1, no bending, coarse surface hair bar processing.
2, when loading, the material head should be aligned with the chuck hole, gently hit into, not allowed to disrupt the knock.
(2) Program-controlled turning lathe:
According to the process requirements for the work step program spindle speed, tool rest feed, tool rest trajectory and continuous offside and other items of pre-selection. Put the electric knob in the position of "adjusting" for test run, confirm no problem, and then put the electric cyclone in the automatic or semi-automatic position for work.
