JTEKT's current GE6i documentation confirms the same general large cylindrical grinder platform with Ø560 mm swing, Ø550 mm grinding diameter, 2,500 mm center-distance option, Ø610 × 75 × Ø254 mm standard wheel and an 11 kW wheel spindle motor.

Applications & Suitable Workpieces

The used TOYODA GE6-250 is particularly suitable for precision external cylindrical grinding where both workpiece length and diameter require a rigid, heavy-duty machine platform.

Typical applications include:

Long transmission shafts and drive shafts
Machine tool spindles and spindle shafts
Industrial rollers and precision rolls
Large bearing journals
Hydraulic rods and cylindrical components
Motor and gearbox shafts
Heavy equipment shaft components
Energy equipment components
Construction and agricultural machinery parts
General precision OD grinding for long cylindrical workpieces

Its 2,500 mm between-centers capacity and Ø550 mm maximum grinding diameter make it especially useful for manufacturers that need to process larger workpieces without moving to an oversized specialty grinder. JTEKT also positions the GE6 family for sectors including energy, industrial machinery, and agricultural/construction machinery.

FAQ

What is the maximum grinding capacity of the TOYODA GE6-250?
