AI Description
BetaCapabilities
The Karstens cylindrical grinder is a precision metal-working tool designed to produce smooth, accurate cylindrical surfaces on various workpieces. With a center height of 180mm and grinding capacity up to 360mm diameter, it handles parts weighing up to 250kg between centers. The 400mm grinding wheel operates at 450rpm with a peripheral speed of 35m/s, delivering fine finishes with adjustments as precise as 0.08mm—ideal for tight tolerances.
Industries & Uses
This machine serves manufacturers across automotive, hydraulics, bearing production, and general engineering sectors. Small to mid-sized job shops use cylindrical grinders to produce shafts, pins, spindles, and other precision components. It's equally valuable for tool & die shops and contract manufacturers who need reliable grinding capability without the expense of new equipment.
What to Check When Buying
When inspecting a 1974 Karstens, pay close attention to spindle runout and bearing condition—these directly affect surface finish quality. Check the grinding wheel for cracks or imbalance, and verify the fine-adjustment mechanism operates smoothly. Request maintenance records and ask about coolant system integrity, as these machines demand proper fluid management. Inspect the machine bed for wear or damage, and confirm all controls and the display function correctly. An on-site test run is essential to assess overall performance.
