FAQ

Is the Okamoto PSG63DX a fully automatic surface grinder?

The used Okamoto PSG63DX supports automatic grinding feed functions, including longitudinal table movement, cross feed, and adjustable wheelhead downfeed. It also provides manual controls for setup and adjustment. It is an automatic precision surface grinder rather than a machine that should automatically be classified as a fully CNC-controlled grinding center.

What size workpieces can the Okamoto PSG63DX handle?

The PSG63DX has a 605 × 300 mm working table and a standard 600 × 300 mm magnetic chuck. Its maximum permissible load is 420 kg, including the chuck. With a reference chuck weight of approximately 100 kg, the remaining load allowance is approximately 320 kg before accounting for any additional fixtures. Actual workpiece suitability also depends on its shape, height, clamping method, and grinding requirements.

Can this used Okamoto surface grinder handle precision mold and tool components?

Yes. The PSG63DX is designed for precision surface grinding applications, including mold plates, tool components, and machined metal parts. Its nominal vertical downfeed settings allow fine grinding adjustments. Actual achievable accuracy and surface finish depend on machine condition, wheel selection, setup, and operating conditions.

Will the Okamoto PSG63DX work with a 380V, 400V, or 415V power supply?

The PSG63DX reference specifications include Japanese three-phase power configurations such as 200V and 220V. The electrical nameplate of the actual machine must be checked before installation. A suitable transformer or electrical adaptation may be required for facilities using 380V, 400V, or 415V power.
