Used Swiss KELLENBERGER KEL-VARIA US 175/1000 CNC Grinder

The machine is equipped with a FANUC Series 300i Model A CNC control, with an upgraded conversational programming interface for easier setup and operation. Its grinding configuration includes two external grinding wheels and one internal grinding spindle, allowing OD grinding, ID grinding and face grinding to be completed in a single setup for suitable workpieces.

Hydrostatic X/Z guideways and the B-axis provide the rigid, smooth motion required for high-precision cylindrical grinding. Seller-reported machining accuracy is approximately 1 μm, making this pre-owned Swiss grinder an attractive option for manufacturers seeking precision grinding capability without the investment required for a new premium machine.

Technical Specifications

Applications & Suitable Parts

This used KELLENBERGER universal cylindrical grinder is particularly suitable for manufacturers producing high-precision rotational components, including:

• Precision shafts, spindles, sleeves and bearing journals
• Gear shafts, splined shafts and transmission components
• Machine-tool spindles and pneumatic spindle components
• Hydraulic pump shafts, valve spools and precision valve components
• Aerospace precision shafts and rotating components
• Cutting tools, gauges, mandrels and precision fixtures
• Punches, ejector pins and precision mold components
• Semiconductor and optical-equipment precision parts
• Carbide and hard-alloy cylindrical components
• Prototype, tooling, small-batch and high-precision component production

Its combination of internal, external and face grinding is particularly useful when manufacturers want to reduce repeated clamping and maintain better dimensional relationships between multiple ground surfaces.
