SHIGIYA also lists the GP-20 family for general industrial machinery and tooling-related applications.
FAQ
Is the SHIGIYA GP-20 a CNC cylindrical grinder?
No. The GP-20 is SHIGIYA's conventional plain cylindrical grinder series. According to SHIGIYA, the series includes an F-type manual feed version, H-type hydraulic feed version and A-type automatic infeed version. The exact configuration of a particular used GP-20 should be confirmed from its machine specification before purchase.
What is the maximum workpiece size for the SHIGIYA GP-20?
The GP-20 has a 200 mm swing over the table and a standard maximum grinding diameter of 100 mm. Distance between centers is available in 250 mm or 500 mm configurations, with a maximum load of approximately 20 kg between centers.
Can the SHIGIYA GP-20 be used for grinding shafts?
Yes. The machine is designed for external cylindrical grinding and is well suited to precision shafts, pins, rollers, sleeves and similar rotational components, provided the workpiece dimensions and weight remain within the machine's capacity.
What grinding wheel size does this used SHIGIYA GP-20 use?
The supplied machine specification indicates a Ø280–Ø355 mm outside diameter, 25–50 mm width and Ø127 mm bore. SHIGIYA's standard GP-20 reference specifies a Ø355 × 32 × Ø127 mm wheel, so buyers should confirm the actual wheel and guard configuration before ordering.
