Gear grinding machine for mass-production ZE15/24: Machine tool

Mitsubishi’s Technology Heritage Continues in Our Latest Efficient and Precise Gear Grinding Machine

Gear grinding machine for volume production ZE15B

Feature

Updated Components Further Reduce Cycle Times

Shorter down times
The twin tailstock reduces down time caused by tooth meshing at workpiece exchange position.
Shorter grinding time
The high-speed, high-rigidity main spindle that incorporates the built-in spindle and the high-accuracy angular bearing achieved spindle speed of 6,000 min^-1.
Shorter dress time
A newly developed high-speed, high-rigidity dresser improves dressing conditions and reduces dressing time.

Further Advanced Automation and Operability

Operability is substantially improved by automating tooth meshing between the grinding wheel and the dresser as well as between the grinding wheel and the workpiece that has been done manually on conventional machines.
