Smk204 Internal Thread Grinding Machine

  1. 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.
  2. Double grinding wheel composite grinding technology, one clamping can realize the outer circle, end face, internal thread composite processing of ball nut;
  3. Full closed-loop control system, online automatic measurement, can automatically measure the position of the ball nut reverser hole;

Machine Features

  1. Large outer diameter can be grinded: Φ150mm; Female thread diameter: Φ20-Φ100mm, length: 200mm;
  2. 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
