Tsudakoma's specially designed double-lead worm gears with full-depth gear teeth
The setting of the lead amount on this gear system is different depending on the rotating direction of the worm wheel and worm spindle - change of gear module.

The center rod moves by turning the handle. The pushing force is multiplied through the small and large rollers, and is tranmitted to the movable jaw , then stable and strong clamping torque is achieved.

Max. speed of 17,000min^-1 ( MHS-4017H ) is realized, employing a built-in motor and grease sealed bearings under the pressure-preloaded system. It assures the lineup of various spindles which correspond to low-speed heavy-duty cutting as well as high-speed machining.
