Requirements for high-speed grinding of CNC grinding machines

To achieve high-speed grinding, there are certain requirements for grinding machines, grinding wheels, grinding wheel spindle structure, motors, protection, and cooling. 1. requirements for grinder structure:

In the grinding process, due to the increase of the linear speed of the grinding wheel, the increase of feed and the increase of grinding force, the internal grinding machine can not have vibration, and it requires sufficient rigidity. When the vibration generated by the grinder should also have sufficient rigidity. There are many factors in the production of CNC grinding machine, grinding wheel guide rail, grinding wheel and motor and pulley have a certain impact, so it is necessary to make appropriate improvements to avoid vibration.

The gap between the grinding wheel spindle and the bearing of the CNC grinding machine should be appropriately increased. Therefore, after the speed of the grinding wheel is increased, the friction between the surface of the shaft and the bearing will increase, and it is easy to cause the phenomenon of holding the shaft due to heat expansion. Generally, the gap between the grinding wheel spindle and the bearing is between 0.03 mm-0 mm.

Grinding wheel headstock and asked not more than 40 degrees, and to take circulation cooling to reduce the bearing temperature.

1. high-speed grinding on the workpiece, grinding wheel, motor requirements:

1. The speed of the workpiece should be increased accordingly.

2. The grinding wheel must choose a high-speed grinding wheel, and choose the appropriate grinding wheel according to the line speed of the grinding wheel.

3. The belt of the grinding wheel should adopt the unloading device.

2. requirements for cooling protection

In order to prevent the grinding wheel from breaking during high-speed rotation and causing accidents, the grinding wheel protective cover must be thickened and the opening angle of the grinding wheel protective cover must be reduced.
