High-Performance Superabrasives
Superabrasives
Ultra-hard materials require superabrasive grinding technologies that push technical performance limits. Winterthur Technology offers a complete range of Cubic Boron Nitride (CBN) and diamond grinding tools. Engineered for extreme hardness, high thermal conductivity, and micro-tolerances, our superabrasive solutions power demanding operations in round cutting tool manufacturing, powertrain, bearing, and aerospace industries.
Complete Range
Our superabrasives
portfolio
Vitrified CBN Grinding Wheels
Wear-resistant ceramic-bonded CBN wheels engineered for high material removal rates, extreme profile retention, and long dressing intervals on iron alloys (e.g. hardened steels) and nickel alloys.
Depending on the application, suitable bonding systems are available, ranging from extremely porous to extremely wear-resistant, or innovative 3D-printed specifications.
3D-Printed & Precision-Structured CBN Tools
Additively manufactured superabrasive tools for demanding internal and face grinding. Featuring digitally engineered internal cooling passages, surface grooves, and uniform grain distribution as well as absolute homogenous layer structure.
Hybrid & Resin-Bonded Diamond & CBN Wheels
High performance fluting, gashing, and relief grinding wheels built with polyimide and advanced hybrid bonds with copper core for tungsten carbide and PCD/PCBN round tool and insert manufacturing.
Electroplated Diamond & CBN Tools
Precision single-layer tools with exact profile contours and high stock removal for nickel alloys, iron alloys and ceramics. Widely used to machine specialized gearbox components.
Diamond & CBN Fine/Face Grinding Discs
Segmented wheels, equipped with round or hexagonal pellets designed for high-efficiency double-disc flat finishing and lapping replacement.
Dressing Systems
Precision-engineered diamond dressers for rotary dressing with form (CNC) and profile (plunge) dressing rolls. High end dressing equipment (spindles). Sharpening rings, and conditioning stones.
Innovation & Quality
Advanced superabrasive & manufacturing technologies
Additive 3D Tool Printing
Design Freedom: Digital 3D modeling enables custom wheel geometries, optimized surface slots, and integrated internal coolant channels constructed layer-by-layer.
Direct Coolant Delivery: Integrated cooling channels deliver cutting fluid directly into the grinding interface, lowering thermal load on workpieces.
Superior Efficiency: Achieves up to 40% higher material removal rates or significantly lower grinding forces compared to standard non-patterned wheels.
Advanced Hybrid & Polyimide Bond Systems
Form Retention & Free Cutting: Copper-core hybrid formulations (such as X-Series) combine rapid stock removal with outstanding form holding during heavy fluting passes.
Thermal Stability: Polyimide and hybrid matrixes withstand elevated grinding temperatures, minimizing dressing frequency and increasing parts per truing cycle.
EDM Dressable: Copper-bonded hybrid wheels allow accurate re-profiling via electrical discharge machining (EDM).
High-Porosity Vitrified CBN Matrixes
Open Porous Structure: Specially formulated synthetic glass bonds reduce total bond volume while matching CBN grains to prevent micro-cracking.
Keep a cutting edge: Maintains sharp cutting edges over long production runs, extending wheel service life and dramatically reducing cycle times.
Cool Cutting Performance: Open pore networks facilitate fluid flushing and rapid chip evacuation in deep plunge and bore grinding operations.
