Smk204 Internal Thread Grinding Machine
- It is especially suitable for grinding large nuts. It can be applied to the dressing of grinding wheels with complex shapes, and can adapt to different specifications of steel balls.
- Double grinding wheel composite grinding technology, one clamping can realize the outer circle, end face, internal thread composite processing of ball nut;
- Full closed-loop control system, online automatic measurement, can automatically measure the position of the ball nut reverser hole;
Machine Features
- Large outer diameter can be grinded: Φ150mm; Female thread diameter: Φ20-Φ100mm, length: 200mm;
- There are two ways to correct the nut raceway grinding wheel: one adopts the formed diamond roller, and each specification of steel ball is equipped with a diamond roller. One is the use of disc-shaped diamond roller (SMK203 does not have this function), the use of X and W axis CNC interpolation correction, a disc wheel can adapt to all specifications of steel balls, especially suitable for the grinding of large nuts. Grinding wheels of any shape can be used
