Specification note: the supplied machine data states a 1500 mm grinding length, while SHIGIYA's manufacturer reference for the GP-30B 150H lists a 1600 mm distance between centers. These are not necessarily contradictory: usable grinding length and nominal center distance can differ. SHIGIYA's published standard wheel specification is Ø405 × 50 × Ø152.4 mm with a 33 m/s peripheral speed.

For quotation purposes, the actual configuration should be confirmed before shipment because tooling, electrical specification and optional equipment can vary between individual used machines.

Applications & Suitable Workpieces

Used SHIGIYA GP-30B 150H OD cylindrical grinder is especially suitable for workshops that need to grind relatively long cylindrical components while maintaining controlled diameter, roundness and surface finish.

Typical applications include:

Long shaft and transmission shaft OD grinding
Motor shaft and spindle grinding
Hydraulic rod and piston rod finishing
Roller and cylindrical component grinding
Bearing journal and stepped shaft finishing
Machine-tool spindle repair and reconditioning
Toolroom and maintenance grinding
Low-to-medium volume precision component production
Automotive, machinery, mold, hydraulic and general engineering applications

Its long grinding capacity makes it particularly relevant for buyers searching for terms such as used cylindrical grinder, used Japanese cylindrical grinding machine, SHIGIYA grinder for sale, 1500mm cylindrical grinder, long shaft grinding machine, and used OD grinder.

FAQ

Is the SHIGIYA GP-30B 150H a CNC cylindrical grinder?

No. The GP-30B 150H is a conventional hydraulic cylindrical grinder rather than a full CNC grinder. SHIGIYA identifies the H version as having manual grinding-wheel feed combined with hydraulic table feed, making it suitable for operators who prefer straightforward conventional grinding control.

What is the grinding length of this used SHIGIYA GP-30B 150H?

The supplied machine specification gives a 1500 mm usable grinding length. SHIGIYA's series specification lists the GP-30B 150H with a nominal 1600 mm distance between centers, so buyers should distinguish between center distance and actual usable grinding length.

What grinding wheel size can the SHIGIYA GP-30B 150H use?

The supplied configuration accepts approximately Ø320–405 mm grinding wheels, with widths from 25 to 75 mm and a Ø152.4 mm bore. SHIGIYA's standard GP-30B specification lists a Ø405 × 50 × Ø152.4 mm wheel and a maximum peripheral speed of 33 m/s.

What kind of parts can I grind with this machine?

This machine is well suited to long shafts, rollers, spindles, hydraulic rods, bearing journals and other precision cylindrical components. If you send us your workpiece diameter, length, material and required tolerance, the machine's suitability can be checked against your application.
