Important Specification Note

The supplied technical information lists:

X-axis travel: 2300 mm
Z-axis travel: 1000 mm

For a conventional cylindrical grinder, these axis values may require confirmation because longitudinal movement is commonly associated with the Z axis.

Therefore, before publishing a final technical datasheet, I recommend verifying the actual CNC axis configuration.

FAQ

What is the maximum grinding capacity of this used SIMMONS cylindrical grinder?

The machine is specified for workpieces up to approximately Ø650 mm in diameter and 2500 mm in grinding length, making it suitable for long shafts, industrial rollers and other large cylindrical components.

Is this SIMMONS grinder equipped with a Fanuc CNC control?

Yes. The machine is equipped with a GE Fanuc CNC control system together with an industrial XYCOM operator interface for machine operation and grinding cycle control.

Can this machine grind long precision shafts?

Yes. With a grinding length of approximately 2500 mm, this machine is particularly suitable for long shafts, rotors, rollers, transmission components and other precision cylindrical workpieces.

Does this cylindrical grinder use a hydrostatic spindle system?

According to the supplied machine specifications, the grinder incorporates a hydrostatic spindle and hydrostatic precision guidance configuration, designed to support smooth movement and high-precision grinding.

Can this SIMMONS grinder achieve mirror-finish grinding?

The machine is designed for high-quality precision cylindrical grinding and may be used for mirror-finish applications when the correct grinding wheel, dressing method, coolant, workpiece material and grinding parameters are used. Final achievable surface roughness should be confirmed by an actual grinding test.
