Nowadays, CNC lathe processing is no longer a mysterious process, many companies will now use it, but not everyone has the right technology. In order to achieve the ideal conditions of use, coolant should be used in CNC lathe processing or a rigid blade should be selected.

So how to choose the parts processed by CNC lathes?

First: Reasonable choice of tools:

1. In the rough turning process, you should choose a tool with high strength and good durability to meet the requirements of large back cut and large feed volume in the rough turning process.
2. When finishing turning, you should choose tools with high precision and good durability to ensure the requirements of machining accuracy.
To
3. In order to reduce the tool change time and facilitate tool setting, machine clamped knives and machine clamped knives should be used as much as possible.

Second: Reasonable choice of fixtures

1. Try to use general fixtures to clamp the workpiece and avoid using special fixtures;
2. The part positioning datum coincides to reduce positioning error.

Third: Determine the processing route

1. It should be able to guarantee the processing accuracy and surface roughness requirements;
2. The processing route should be as short as possible to reduce the idle time of the tool.

Fourth: The relationship between processing route and processing allowance

At present, when the CNC lathe processing technology has not been popularized, the excess margin on the blank, especially the margin containing the forging and casting hard skin, should be arranged on the ordinary lathe for processing. If you need to process on a CNC lathe, you need to pay attention to the flexible arrangement of the program.

Firth: Key points of fixture installation

At present, the connection between the hydraulic chuck and the hydraulic clamping cylinder is realized by a tie rod. The clamping point of the hydraulic chuck is: first remove the nut on the hydraulic cylinder through the bracket, remove the traction tube, and pull The tube is drawn out from the rear end of the spindle, and then the chuck fixing screw is removed through the bracket, so that the chuck can be removed.
