NC lathe turning process processing

in the process of NC lathe turning, we should pay attention to the case that we care about external inventions due to mistakes: the process of NC lathe processing is similar to that of ordinary lathe, but because NC lathe is a clamping device, continuous automatic processing completes all turning processes, so we should pay attention to the following aspects of our website

1. Select cutting parameters reasonably

2. Reasonable selection of tools: (1) during rough turning, tools with high strength and good durability should be selected in order to meet the requirements of large back feed and large feed during rough turning. (2) When finishing turning, we should choose tools with high precision and good durability to ensure the requirements of machining accuracy

(3) in order to reduce the time of tool change and facilitate tool setting, machine clamped knives and machine clamped blades should be used as much as possible

and cannot meet the requirements of high-precision measurement 3 Reasonable selection of fixtures: (1) try to use general fixtures to clamp the workpiece, and avoid using special fixtures; (2) The positioning datum of parts coincides to reduce the positioning error

4. Determine the processing route: the processing route refers to the motion track and direction of the tool relative to the part during the processing of the NC machine tool. (1) It shall meet the requirements of machining accuracy and surface roughness; (2) The processing route should be shortened as far as possible to reduce the tool idle travel time. Rotor pump

5 Connection between processing route and machining allowance: at present, under the condition that numerical control lathes have not reached popularity and ELG and idasso cooperate to develop light materials for Chery electric vehicles, generally, excessive allowance on the blank, especially the allowance containing forged and cast hard skin, should be arranged on the ordinary lathe for processing. If it is necessary to process with a numerical control lathe, pay attention to the flexible arrangement of the program

6. Key points of fixture installation: at present, the connection between hydraulic chuck and hydraulic clamping cylinder is realized by pull rod, as shown in Figure 1. The key points of hydraulic chuck clamping are as follows: first, remove the nut on the hydraulic cylinder with a hand, remove the pull tube, and pull it out from the rear end of the spindle, and then remove the chuck fixing screw with a hand, and then remove the chuck
