Gear Hobbing Machines

Mitsubishi Heavy Industries America offers a wide variety of CNC-controlled gear hobbing machines to meet the requirements of the high-volume producer as well as the small-lot job shop.

Ranging in part sizes from 10mm to 1,000mm, you can find an MHIA machine that will cut your gear.

Mitsubishi Heavy Industries is the only manufacturer in the world to have developed a completely new design for dry cutting. This new machine design, along with our SuperDry hob cutters provide the ideal solution to your dry cutting challenges.
