Grinding Technology
 
.....
Vertical centerless Grinders (VSR), what is that ?
Vertical means in our Grinders the grinding wheel (1) is above the Reg.-Wheel (2) (vertical)

An infeed slide is pushing the workpiece between the grind wheel and the reg- wheel.The grinding-wheel turns with high speed, the reg-wheel is grinding with low rpm the rpm´s of the workpiece.

Centerless means the workpiece is not clamped anywhere. It turns free in the infeed slide and on the reg-wheel.

 
 
Grinding before centre or the closed triangle of forces.
Based on the geometrical position of grind- and reg- wheel and the workpiece itself we find a closed triangle of forces. That helps to guide the part nice and safe over the full grind cycle.

Options for Economical Grinding
 
Gaging during grinding the "Inprocess-Gaging".
We highly recommend the Inprocess Gage for more effectiveness in your process.

During the grinding process the gage unit 1 is checking the actual diameter of the workpiece.

The feed rates are changed from the gage unit based on diameter grind off.

Options for economical Production

Grinding procedure

1. Rapid motion forward (until contact) of
    workpiece with grind- and reg- wheel.
2. Rough grind
3. Medium grind
4. Finish grind
5. Rapid motion back

Each single step is electronically driven and controlled.

The chart shows the cycle.
