The World's First Dry Grinding Gear Grinder

This state of the art process removes the need for cooling oils during the hard finish grinding of the gear after the heat treatment. Roughly, 90% of the stock allowance in the first pass, using a hobbing tool is removed and subsequently in the second pass, a grinding wheel removes the remaining stock without causing problems of overheating the workpiece, which results in a fully dry process.

The innovative structure with two spindles actuated by the linear motors and the use of more channels simultaneously ensures a chip-to-chip time of less than two seconds. The SG 160 splits the X-axis into two liner slides, each of which carries tool spindles. Both work spindles are in full position control at any time.

The new grinding SG 160 SKYGRIND of Samputensili ensures cycle times at a low comparative cost to traditional manufacturing solutions in the automotive industry.

The SG 160 SKYGRIND is an amazingly productive machine, even faster than traditional dual table grinding machines, featuring a small footprint and lower cost for auxiliary equipment. The most important piece however is the eliminated need for cutting tools creating an extremely green machine.
