Gear Grinder Eliminates Need for Cutting Oils
Samputensili’s SG 160 Sky Grind, available from Star SU, is said to eliminate the need for cutting oils during the grinding of gears after heat treatment.
Samputensili’s SG 160 Sky Grind, available from Star SU, is said to eliminate the need for cutting oils during the grinding of gears after heat treatment. The machine features two spindles, one for skive hobbing and one for generating grinding. The two spindles are actuated by linear motors and, when combined with the use of more channels, ensure a chip-to-chip time of less than 2 sec., the supplier says.
According to Star SU, the Sky Grind removes 90 percent of the stock allowance with the first pass using a skive hobbing tool. With the second finishing pass, a grinding wheel removes the remaining stock. This process avoids heating the workpiece excessively without the use of oil-based lubricant resulting in a completely dry process.
The company says that the machine is faster than traditional dual-table grinding machines and has a smaller footprint and lower cost of investment for auxiliary equipment. By eliminating cutting oils, the machine is also environmentally friendly.
