Center hole grinding machine

Center hole grinding is becoming more and more of an issue for precise grinding parts. If several diameters have to be ground on a shaft in different work steps, you need an accurate center hole. With the help of our center hole grinding machine ZSM (System Fischer, Dottikon) you grind the center holes with a concentricity of 0.001mm.

The center grinding machine can be adapted precisely to your requirements and workpieces thanks to a wide range of equipment options.

There are many options available. These range from automating individual work steps to fully automatic machines that automatically measure the clamped component using a laser and grind it using a mounted point.

For more information of the machine, please refer to the flyer.

With a lot of experience to the optimal result

Grinding principle:
1. Rotary move of the grinding wheel
2. Stroke move of the grinding wheel
3. Rotating workpiece

Result:
A cross hatch pattern with oil pockets that provides optimum oil retention in the center holes

Swivelling grinding head

With the swivelling head the grinding angle can be adjusted between 0° and 90°

Highest precision

The machine achieves a concentricity accuracy of 0.001mm

Clamping of the workpieces in the chuck

With the help of the three adjustable quills even workpieces with an inaccurate surface can be clamped and aligned
