CBN and diamond tools for stable, productive manufacturing processes
EHWA develops and supplies custom-engineered grinding, dressing, and cutting tools – with personal technical consulting for industrial customers across Europe.
Steel · fine turned
A stable metal carrier for the abrasive rim. Fine concentric machining marks are created when the faces are turned.
Metal bond
Sintered metal matrix with strong grit retention. For low-wear form and profile grinding, for example on glass and ceramics.
Material & version
Illustrative assembly
Start from your process
Six machining tasks EHWA designs tools for. Each page states bond, grit, and dimensions along with the process limits.
Camshaft Grinding
Profile-accurate cam contour over long production runs – longer dressing intervals with reduced thermal load.
Crankshaft Grinding
Tool-life-optimized grinding of high-alloy quenched-and-tempered steels and cast materials with a hard surface layer and tough core.
Plunge Grinding of Gearbox Components
Shaft shoulders, bearing and seal seats in high-volume production – controlled material removal with long dressing intervals.
CV Joint Grinding
Cage windows and ball raceways with high form accuracy and minimal thermal impact.
Bearing Grinding
External, internal, and raceway grinding of 100Cr6 bearing rings – tight tolerances at economical cycle times.
Indexable Insert Grinding
Peripheral, clearance, and face surfaces on carbide, cermet, and PCD/PCBN with reproducible cutting-edge quality.
Tool Grinding
Process-stable flute, profile and cylindrical grinding of drills, end mills and micro rotary tools with defined free-cutting behaviour.
Three tool families
Grinding and honing, dressing, and cutting – from a single source and engineered to work together.
Grinding & honing tools
External-cylindrical, profile, plunge, and double-face grinding wheels, plus honing stones.

Dressing tools
Diamond dressing rollers, cup dressers, and single-point, profile, and multi-grain dressers.

Cutting tools
Turning, drilling, and milling tools with PCD, PCBN, and single-crystal cutting edges.

The proof is the argument
Tools are engineered around the machine concept, workpiece geometry, and process requirement – not picked from a catalog. Where a customer has approved disclosure, we back up the result with figures from the running process.
Example, camshaft grinding: CBN profile grinding of a nodular cast-iron camshaft, specification B151 L200 VEWN, wheel diameter Ø 650 mm, peripheral speed 80 m/s.
All figures come from approved customer processes and apply to the setup documented there. They are evidence, not a guarantee.
Tool life and dressing interval from CV-joint grinding; roughness from grinding carbide indexable inserts. Each figure appears with its process parameters on the respective application page (German).
