Use a low speed, high torque, rigid machine tool to machine the worm;

It is not necessary to vibrate the knife when machining the workpiece, no abnormal noise, and good surface finish;

Processing efficiency needs to be 15% higher than ordinary machine tools.

According to the requirements of the drawings, the worm is turned, the cutting force is large, and the worm has a large pitch. The Shenyang CAK5085 manual three-speed servo machine is selected, and the torque is high during low-grade machining;

According to the worm pitch, a large worm blade can meet the requirements of cutting worms;

The clamping method uses a clip and a top to meet the high torque transmission of the workpiece and maintain stability;

According to the rigidity of the machine tool and the large torque, the forming tool is used for straight cutting.

The processing time of this part is 7 minutes and 22 seconds, the overall processing time is 86 minutes, which is about 27% higher than the original processing time;

The surface finish has also been greatly improved to fully meet customer requirements.
