The opening of the JIMTOF machine tool show in Tokyo, Japan marked the debut of MHIMTC's new MSS300 super skiving gear machine. This new machine was developed to maximize the advantage of MHI's new three tier skiving tool released earlier in 2016.
The new MSS300 is designed specifically for the high speed manufacturing of automotive internal ring gears. With a maximum outside diameter of 300mm, the MSS300 brings flexible, high volume internal gear skiving to internal gear manufacturing.
In addition to internal gear cutting, the MSS300 is also capable of cutting parts with restrictive geometries, such as stacked pinion gears. Many applications that would have been shaped or manufactured in two parts previously can now be cut with the super skiving process.
The all-new machine features an ultra-rigid, powerful (33 KW) tool spindle capable of 6,000 rpm and +/- 30 degrees of helix angle. The direct drive work table offers 3,000 rpm with high torque and stable synchronization. The six axis Fanuc 31i CNC controller utilizes graphic data entry screens for quick part setup.
For high speed operation, a ring loader is integrated into the machine design and is available 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 MHI's newest super skiving tools, conventional pinion-type skiving tools are completely compatible and are utilized for certain applications. MHI's new super skiving tools typically produce three to five times more parts than conventional skiving tools.
Deliveries of the new MSS300 will begin in the second quarter of 2017. The MSS300, along with the innovative super skiving tools from MHI have established a new benchmark in productivity and process quality.
