Product Details

Machine Tool Main Characteristics:

This machine tool is a centerless grinding machine with wide grinding wheels, which is mainly used to grind the outer surface of various bearing outer rings with a diameter of Φ10-100mm or Φ10-200mm and other similar equal diameter parts.
The machine tool also has an automatic cutting mechanism and a hydraulic and electrical control system for the manipulator. Therefore, after the necessary manipulator unloading device and other special devices are equipped, the machine tool can also be used for cutting and grinding.

Grinding Bed:

The normalized heat treatment and natural aging treatment of high-quality castings are used to stabilize the internal structure, ensure strong wear resistance and small deformation during use.

Grinding and regulating device:

The machine tool adopts 500/600mm outer diameter grinding wheel, which has strong cutting force and high utilization rate of grinding wheel.
The thickness of the grinding wheel is wider, and the grinding allowance can be increased in one pass during the grinding, reducing the number of repeated grinding and improving the production efficiency.
The machine tool is a double-sided mobile layout, the bracket is fixed on the bed, the guide wheel frame is only used for adjustment movement, the position of the workpiece is unchanged, it is easy to be equipped with various feeding devices, and it is convenient for automation.
Both the grinding wheel and the spindle of the guide rail adopt dual-support five-piece short-bearing bush oil film bearings, which have good rigidity and can meet the needs of heavy-duty grinding and precision grinding.

Feeding device:

The grinding wheel adopts liquid static pressure guide rail, sensitive movement can achieve micro feed and has a certain shock resistance, the guide rail is not easy to wear.

Dressing device:
