Kehren d grinding machine

Kehren d grinding machine 

Surface grinding machines with two rotary tables and vertical grinding spindle:

D machines are used wherever high demands are placed on the reduction of machining time, stock removal rate, high surface quality, and plane parallelism of the workpieces. These types of machines are used in tool and mold making, standard mold and printing machine manufacturers, as well as general mechanical engineering.

D machines have a powerful vertically arranged grinding spindle. A segmented quick-action chuck is adapted to this grinding spindle, which enables a high degree of utilization of the grinding segments.

The use of double round table flat grinding machines enables the unit times to be reduced by up to 10% using 8 parallel setups.
