Used TOYODA GE6-180 Cylindrical Grinder

Used TOYODA GE6-180 external cylindrical grinder, originally manufactured in Japan, is designed for high-precision grinding of long and large-diameter shafts, rolls, spindles and rotor components.

With a 1,800 mm grinding length, grinding capacity up to Ø560 mm, a Ø610 mm grinding wheel, and a hydrostatic wheel spindle design, this machine is a strong option for manufacturers looking for Japanese grinding technology without the investment required for a new large cylindrical grinder.

A previous machining test reportedly achieved approximately 1 μm straightness on a workpiece over one meter long and around 0.3 μm roundness. Final accuracy should be confirmed under the buyer's required test conditions before purchase.

Technical Specifications

Accuracy note: The approximately 1 μm straightness and 0.3 μm roundness values are reported machining-test results rather than an unconditional accuracy guarantee. Acceptance criteria should be agreed according to workpiece material, length, diameter, grinding wheel, temperature and measuring method.

The GE6 family is JTEKT/TOYODA's large cylindrical grinding platform. JTEKT's current GE6-series documentation also identifies the machine family as being designed for large workpieces and high-precision cylindrical grinding.

Applications & Suitable Workpieces

Used TOYODA GE6-180 is especially suitable where long workpiece capacity, large grinding diameter and precision OD finishing are required.

Typical applications include:

• Long shaft grinding: transmission shafts, drive shafts, motor shafts, machine shafts and precision spindle shafts.
• Rotor components: compressor rotors, generator shafts, industrial rotor shafts and selected aerospace-related rotating components.
• Roll and roller grinding: precision rollers, guide rolls and industrial cylindrical components.
• Machine tool components: spindle components, sleeves, arbors and precision cylindrical machine parts.
• Gear and transmission components: gear shafts, pinion shafts and hardened transmission parts.
• Industrial equipment components: compressor shafts, printing machinery rollers, textile machinery shafts and packaging equipment components.
• Tool and mold manufacturing: cylindrical tooling, mandrels and long precision mold components.

For factories producing large or long cylindrical components in small batches or multiple specifications, the GE6-180 can be particularly attractive because it provides significantly greater workpiece capacity than standard medium-size cylindrical grinders.
