Mitsubishi Heavy Industries’ MMS300 Super Skiving gear machine is intended to maximize the performance of the company’s three-tier skiving tool. Designed for the high-speed manufacturing of automotive internal ring gears with maximum outside diameters of 300 mm, the machine brings flexible, high-volume internal gear skiving to internal gear manufacturing. In addition to internal gear cutting, the MSS300 is capable of cutting parts with restrictive geometries, such as stacked pinion gears. Many applications that would have been shaped or manufactured in two parts can now be cut with the Super Skiving process, the company says.

The machine features an ultra-rigid, 33-KW tool spindle capable of 6,000 rpm and a helix angle of ±30 degrees. The direct-drive worktable offers 3,000 rpm with high torque and stable synchronization. The six-axis FANUC 31i CNC utilizes graphic data entry screens for quick part setup. For high-speed operation, a ring loader can be integrated into the machine as an option. The MSS300 is easily interfaced to robotic, gantry type, basket or conveyer automation.

Although the machine is designed to get the most productivity from the company’s super skiving tools, conventional pinion-type skiving tools are still compatible with it.
