About Winterthur Technology
The Winterthur Technology Group is a globally active manufacturer of bonded abrasives, superabrasives and precision dressing systems for industrial grinding applications. As a process-oriented system supplier, the company develops tailored complete solutions in which the grinding wheel and dressing tool are matched to each other. The portfolio includes vitrified and resin-bonded conventional grinding wheels, hot-pressed tools for steel finishing, vitrified CBN and diamond grinding tools, 3D-printed superabrasive tools with integrated cooling channels, as well as electrolytically bonded diamond and CBN tools and rotary diamond dressers. Applications include gear grinding, profile grinding, surface grinding, cylindrical grinding (OD/ID/centerless) and tool grinding on steel, stainless steel, nickel and titanium alloys and carbide. The group produces at seven sites in Germany, Austria, Sweden, the USA and China; the headquarters of Winterthur Technology (Austria) GmbH is located in Villach. Customer industries include automotive/e-mobility, drive technology, wind energy, tooling and machine tool manufacturing, aerospace and the steel industry.

Abrasives, Bonds and Processes
Aluminum oxide abrasive
Conventional abrasive for precision and general-purpose grinding operations.
Ceramic abrasives (shaped grains, TriWin II)
Shaped ceramic grains for high material removal rates, lower grinding forces and long tool life.
Zirconia abrasive
For tough, highly stressed cutting and removal applications in the steel industry.
Silicon carbide abrasive
Used among other things in roll grinding and resin grinding of hard materials.
CBN (cubic boron nitride)
Superabrasive for ferrous materials and nickel alloys with high profile sharpness and long dressing intervals.
Diamond
Superabrasive for carbide, PCD/PCBN, ceramics and thermally sprayed coatings.
Vitrified bond
Porous bond systems for cool grinding and high profile accuracy.
Resin bond
For vibration-damping, impact-resistant and heavy-duty applications.
Polyimide bond
Thermally stable matrix for flood grinding and tool grinding.
Copper-bonded hybrid bonds (X-Series)
Copper-core hybrid systems for fast stock removal with high shape retention; EDM-redressable.
Electrolytically bonded diamond/CBN tools
Single-layer tools with exact profile contours and high removal performance.
Hot-pressed resin grinding wheels (SlipNaxos)
Heavy-duty tools for descaling and conditioning slabs and billets.
