CITIZEN hard turning

1. What is a hard car?

Hard turning refers to the machining process of turning hardened steel with CBN or ceramic tools. Hard turning technology has good applications in the fields of auto parts processing, precision reducer gear processing, bearing processing and other fields.

2. The advantages of hard cars

Significant reduction in cost/improvement of shape and position accuracy
The initial investment of equipment and the equipment space occupy less than 50% of the grinding machine, and multiple grinding projects It can be implemented in one lathe. Through one clamping, all the processes of outer diameter, inner diameter, arc, free-form surface, etc. can be completed, so the straightness, perpendicularity, and concentricity will be greatly improved. The loading/unloading time is short, so the cycle time can be shortened. Through dry cutting, the coolant can be reduced, and the waste grinding slag can be put into the recycling of the chips, and the burden on the environment can also be reduced.

3. Machine features

The one-piece cast 30-degree inclined bed structure has excellent thermal displacement stability and chip removal, which ensures the stability of the processing dimension displacement and enables high-precision processing . In addition, the sliding guides carefully manufactured by experienced scraping and researching technicians are used for all moving shafts to ensure high rigidity and high vibration damping.

The front bearing adopts a combined structure of a set of ball bearings and a set of roller bearings, which achieves high rigidity while maintaining high precision and stable rotation from low speed to high speed .

The turret that bears cutting force and vibration under harsh conditions can be directly embedded with a turning tool with a 25-angle arbor, thus reducing the transition link of tool installation and shortening The protruding length of the tool ensures high rigidity turning.
