At Wenzel, our commitment to delivering the highest quality parts and tools for oil, gas, geothermal and horizontal drillers drives the investments we make in our machining capabilities. Our latest addition, the GERmh CU-600 CNC cylindrical grinder, brings advanced grinding technology into our machine shop and unlocks a new level of precision and performance for our customers.

What makes the GERmh CU-600 CNC unique
The CU-600 CNC is designed for high-precision cylindrical grinding of both external and internal surfaces. Equipped with advanced CNC controls, it delivers exceptional accuracy, repeatability, and surface finishes that meet the tightest tolerances. Its robust construction and vibration-dampening design ensure consistent results, even on hard and abrasive materials.
Key features include:
- CNC precision control for complex geometries and multi-step grinding operations
- High rigidity for minimal deflection and superior finish quality
- Versatility to handle both small and large-diameter parts
- Capability to grind tungsten carbide and other hard materials with ease
This is not just a grinder—it’s a production asset built as tough as the tools we deliver.
The internal tungsten-carbide-armoured surface of a rotating flow restrictor is ground to exacting precision with the CU-600 CNC cylindrical grinder.
Why it’s a game-changer for our tungsten carbide flow restrictors
Our radial flow bearings (flow restrictors) incorporate tungsten carbide tiles and matrix on both outside (for rotating flow restrictors) and inside (for stationary flow restrictors) surfaces to withstand high wear and abrasive drilling environments. While this makes them incredibly durable, it also makes them extremely challenging to machine. The GERmh CU-600 CNC is purpose-built to handle these materials, producing the ultra-smooth, precise cylindrical surfaces required for proper fit, sealing, and performance.
With this grinder, we can:
- Achieve micron-level tolerances for perfect concentricity
- Produce superior surface finishes that extend component life
- Reduce lead times with faster, more efficient grinding cycles
- Ensure consistent quality from the first part to the last
Applications for cylindrical grinding
While our immediate focus is on tungsten carbide flow restrictors, cylindrical grinding is essential in many industries. This technology is ideal for:
- Precision shafts and spindles
- Bearing journals and housings
- Hydraulic and pneumatic components
- Rolls and mandrels for manufacturing lines
- High-performance parts for oil, gas, aerospace, and defense
If your project requires high-accuracy roundness, tight tolerances, and flawless surface finishes, cylindrical grinding is the answer.
