Tyrolit Face Grinding Wheels | Cup & Straight Wheels for Flange and End Grinding
Tyrolit Face Grinding Wheels are cup-shaped and straight-sided wheels designed for grinding flat faces, end surfaces, flanges, and shoulders on cylindrical or irregular workpieces where the wheel’s side or face performs the cutting action. This operation, common in toolroom, production, and gear manufacturing environments, demands wheels that combine aggressive face cutting with minimal edge breakdown. Tyrolit face grinding wheels are offered in vitrified and resinoid bonds, in diameters ranging from 100 mm to 600 mm, and in aluminum oxide, ceramic, and silicon carbide grains. Cup wheels (Type 6 and Type 11) are the primary choice, as their geometry provides a large grinding surface area while allowing spindle clearance. Applications include grinding the end faces of springs, cutters, gears, and bushings to precise length and squareness; sharpening the faces of milling cutters and reamers; and refacing clutch plates. Tyrolit’s specific bond formulations are designed to self-dress uniformly across the wheel face, preventing the “concave” wear that causes the ground face to become convex. For high-production environments—such as spring face grinding—Tyrolit provides matched-gang sets of cup wheels that grind both ends of a spring simultaneously, holding length tolerance to a few hundredths of a millimeter across thousands of parts. Cool, vibration-free cutting and long dressing intervals are the hallmarks of Tyrolit’s face grinding wheel technology.

Flat, Uniform Wheel Face Wear
Tyrolit bonds wear evenly across the cup face, preventing concave or convex wheel wear that produces out-of-square workpieces and necessitates constant wheel truing.
High Stock Removal Rates without Burning
Open-structure, soft-grade ceramic grit wheels cut cool on hard steel springs and gears, removing up to 1 mm of stock per pass without generating blueing or heat checks.
Matched Gang Wheel Sets for Simultaneous End Grinding
For spring and spacer manufacturers, Tyrolit supplies precisely matched pairs of cup wheels with identical thickness and bond, ensuring identical stock removal from both ends in one cycle.
Specialized Toolroom Wheels for Cutter Sharpening
White aluminum oxide wheels with friable grain provide the sharpness and delicacy needed for dry sharpening of HSS and carbide face mills without pulling the temper.
Quiet, Vibration-Damped Operation
Precision balancing and consistent density reduce spindle vibration, improving the surface finish and extending the spindle bearing lift.
Quick-Change and Adapter Plates Available
Tyrolit wheels can be supplied with integral mounting plates for rapid changeover on dedicated grinding machines, minimizing downtime.
Why Tyrolit Face Grinding Wheels Are Preferred for Spring and Gear Production
Spring end grinding is a high-volume, abrasive-intensive process. A spring manufacturer grinding millions of ends per shift needs wheels that wear slowly and predictably. Tyrolit’s ceramic cup wheels for spring grinding are formulated with a tough, hard bond that resists the abrasive dust generated by the process, and a structure that channels the dust away from the grinding zone, preventing loading and thermal stress in the spring tip. This results in consistent spring free-length and squareness, critical for assembly in automotive valve trains and suspension systems. The reduction in wheel changes per shift significantly increases the output of the spring grinding line. Tyrolit also manufactures large-diameter resinoid cup wheels for grinding the flanges of railway wheels, a highly specialized operation requiring massive stock removal in a single pass under heavy flood coolant.
Selecting Cup Wheels for Toolroom and Production Face Grinding
For general toolroom sharpening, a standard white aluminum oxide cup wheel (38A) in a soft (H or I) grade, with fine grit (60-80), is the versatile choice. For high-production spring grinding, a ceramic grain wheel in a medium-hard grade with a wide, open face. For heavy steel face grinding, a large diameter Type 6 cup wheel is used with a radial face to minimize contact area and maximize unit pressure. Tyrolit’s catalog provides selection tables organized by workpiece material and grinding machine type. The customer support team can also arrange to evaluate the existing grinding process to recommend upgrades.
