The Samputensili SG 160 SKYGRIND is the first machine tool in the world
that can grind gears without using cooling oil.
This extraordinary machine removes most of the stock allowance with the first pass using a hobbing tool. The second finishing pass, carried out by a grinding wheel, removes the remaining stock without overheating the workpiece, therefore resulting in a completely dry process. Its innovative structure with two spindles actuated by linear motors and the use of more channels simultaneously ensure a chip-to-chip time of less than 2 seconds.
