We can calcurate strength, design and manufacture high precision spiral bevel gears as customer need.

5 Axis CNC Milling Large Bevel Gears up to 2000mm dia.

IWASA TECH has introduced the 5-Axis Machining Center for manufacturing large bevel gears based on the Cyclo-Palloid tooth form up to 2,000mm dia. Much has been discussed about green cutting and hard finishing of spiral bevel gears on standard milling machines. This versatile machine will eliminate the need for dedicated bevel machines with expensive tools and accessories. Convincing arguments can be made for the practical use of this technology in the large coarse pitch with low volume bevel gear production. IWASA TECH implements its self-developed TCA program and CAD/CAM system to optimize the large bevel gear design based on the Cyclo-Palloid system, as well as NC program to realize the closed loop system linked with the Coordinate Measuring Machine.
