Medium-sized CNC bearing ring Lip grinding machine

 This series of grinders are used to grind the outer ribs of single or double-row cylindrical roller bearings.

1.Adopting SIEMENS, FANUC^ MITSUBISHI all-digital AC servo control system.

2. grinder  is convenient to operate and adjust.

3.Adopting a high-precision shaft with sleeve for workpiece shaft, the motor of workpiece adopts AC frequency variable motor, frequency variable speed.

4.High rigidity steel is used for the spindles of full-automatic grinder. And a high rigidity, high-precision and high-speed belt shaft is used for the semi-automatic grinder, with the frequency variable speed, grinding at the high-speed of 60m/s.

5.Adopting double-point diamond pen for dressing of the wheel automatically. The section of wheel is a shape of herringbone and double ribs and quadruple ribs can be fit in the fixture at same time and grinding separately. Using two conic faces of the herringbone wheel, it can grind the two ribs in the front and back of the raceway separately. In order to avoid burn of grinding face, a small reciprocating grinding for workpiece can be used simultaneously.

6.AC servo motor drive is used for the carriages of the workpiece and grinding support. With the support of cross roller rail, a micro-oscillation can be achieved during the grinding.
