AI Description
BetaCapabilities
The Willi Göbel GRS-III-2400-SP is a precision CNC external cylindrical grinding machine designed for high-accuracy finishing of cylindrical workpieces. With a 220mm grinding wheel and capabilities handling parts up to 700mm outer diameter, it delivers repeat accuracy under 2µm—ideal for applications requiring tight tolerances. The machine accommodates both small components (100mm diameter) and large industrial parts, making it versatile across production runs of varying scales.
Industries & Uses
This equipment serves automotive suppliers, bearing manufacturers, hydraulic component producers, and general metal fabrication shops. It's essential for finishing crankshafts, pump shafts, spindle components, and precision bushings where surface finish and dimensional accuracy directly impact product performance. Manufacturers moving beyond basic grinding or expanding production capacity often invest in machines like this to meet OEM specifications consistently.
What to Check When Buying
When evaluating this used machine, request complete maintenance records—particularly spindle bearing service history and grinding wheel replacement logs. Inspect the spindle for runout and vibration during operation; verify the 2µm accuracy specification with test cuts. Check the coolant system for leaks or degradation, and confirm the CNC control system operates smoothly with original or compatible software. Ask whether calibration records exist and if the machine has been regularly serviced by qualified technicians.
