SG 160 Dry grinding machine
Discover the new SG 160 : a ground-breaking concept for the dry grinding of gears!

The challenge
Y Z X1 X2 A B1
It is known that when grinding most of the heat is transferred into the workpiece. Reducing friction, discharging the heat and evacuating the chips are the primary technological tasks for the oil-based lubricant. However, the equipment dedicated to the oil treatment (tanks, high-pressure pumps, filtration unit, etc.) absorb 75% of the total energy consumed by a grinding machine, require a massive amount of space and significantly contribute to the costs of investment and maintenance of grinding machines.

Our solution The SG 160 removes most of the stock allowance with the first pass using a hobbing tool, which has the advantage of not heating the workpiece excessively. Subsequently, with the second finishing pass, a grinding wheel removes the remaining stock without causing problems of overheating the workpiece, therefore resulting in a completely dry process.
The SG 160 splits the X-axis of traditional machines into two linear slides (X1, X2), each of which carries one workpiece spindle. In this way both workspindles are under full position control any time.
Your advantage Moreover, its innovative structure with two spindles actuated by linear motors and the use of more channels simultaneously ensure a time of chipto-chip of less than 2 seconds. The final result is an amazingly productive machine, even faster than traditional dual table grinding

Being driven by high dynamic 30 m/s linear motors, changing spindles comes down to less than 2 seconds including simultaneous repositioning of the tools with the Y-Z-A axes.
State of the art Hobbing & Chamfering
Based on a very rigid and unique machine architecture, the SG 160 Sky Grind is the first dry grinding machine for high productivity industries.
+ cost of consumables + total investment + machine footprint
machines, characterized by a very small footprint and a lower cost of investment for auxiliary equipment. More importantly, by totally eliminating the need for cutting oils, the machine is extremely environmental friendly, both towards ecosystems and towards our most valuable resource: the health of working people.
