Product characteristics

Compact and economy machine

One-head and crossrail fixed construction realized to save 45% of space from usual double column type surface grinding machine with two heads.
So the horizontal stroke of grinding head is enough wide, that the work piece which is able to pass between the columns is possible to grind.

Reduce the grinding time

Standard table max. Speed is 35m/min and the spindle motor is 18.5kW, these specifications realize to reduce the rough grinding time.

Improve the grinding accuracy

Minimum increment system of the grinding head is 0.1μm and the sub-micron infeed is possible. In grinding of the thick or thin work piece, the head distortion is head back and high accurate grinding is realized.

Optimum model line-up to the required accuracy

KSL-F

Standard model provides superior performance.

KSL-FX Series

Based on standard model with Hydrostatic slideways, horizontal & vertical grinding heads provides high accuracy
