Tyrolit Double Side Face Grinding Wheels | Precision Parallel Surface Grinding
Tyrolit Double Side Face Grinding Wheels are specialized, highly engineered abrasive tools designed for simultaneous grinding of two parallel surfaces on components such as bearing rings, valve plates, gear blanks, connecting rods, semiconductor wafers, and ceramic seal faces. Double side face grinding is an extremely demanding process that requires two opposed grinding wheels to remove material from both sides of the workpiece in a single pass, achieving micron-level parallelism, flatness, and thickness tolerance. Tyrolit wheels for this application are manufactured using ultra-precision processes to guarantee absolute flatness, uniform density, and segment-to-segment consistency across the entire wheel face. The range includes vitrified, resin, and metal-bonded wheels with conventional and superabrasive grains (diamond & CBN). Tyrolit’s proprietary bond systems allow controlled self-dressing, preventing the wheel loading that causes thickness drift and workpiece burn. The wheels are available in continuous rim, segmented, and button configurations, optimized for different machine kinematic types (rotary carrier, through-feed). For high-volume automotive and hydraulic component production, Tyrolit double side face grinding wheels deliver exceptional process capability (Cpk > 1.67), long dressing intervals, and low cost per part, making them the industry benchmark for parallel surface finishing.

Trusted by Industry Leaders
Absolute Wheel Flatness and Parallelism
Tyrolit’s grinding and lapping machines finish the wheel body to sub-5-micron flatness, ensuring that the wheel imparts an identical degree of flatness to every ground workpiece.
Segment and Button Configurations for Optimal Coolant Flow
Open wheel designs (segmented or button) permit maximum coolant penetration and chip clearance, preventing thermal damage and enabling higher stock removal rates on both sides simultaneously.
Workpiece-Specific Grain and Bond Engineering
From CBN wheels for hardened steel transmission plates to fine-grit diamond wheels for ceramic pump seals, each wheel formulation is custom-tuned to the material’s hardness and thermal conductivity.
Long Dressing Cycles and Self-Sharpening
Tyrolit bonds wear microscopically to expose fresh abrasive without macro fracturing, enabling extended grinding runs between dress cycles and increasing machine uptime significantly.
Reduced Total Part Variation
The combination of wheel flatness and uniform wear characteristics results in exceptionally tight part thickness variation, often reducing post-process inspection reject rates to near zero.
Global Spindle Compatibility
Arbors and mounting systems are manufactured to OEM specifications for all major double disc grinding machine brands, including Koyo, Gardner, Besly, and Diskus.
Why Tyrolit Double Side Face Grinding Solutions Are Essential for Automotive Tier Suppliers
In the production of diesel injector control plates, compressor valve reeds, and automatic transmission clutch plates, the thickness tolerance directly affects the function and noise-vibration-harshness (NVH) performance of the final assembly. Tyrolit’s CBN double side face grinding wheels allow Tier 1 automotive suppliers to grind hardened steel parts from solid blanks to finish thickness in one pass, eliminating the need for pre-grinding and lapping. The wheels’ self-dressing behavior ensures that the 10,000th part is as dimensionally perfect as the first, enabling unattended lights-out production. The reduced scrap rate and faster cycle times compared to traditional two-step processes deliver a rapid return on investment for the grinding system. Tyrolit application specialists work on-site to optimize wheel specification, grinding parameters (wheel speed, feed rate, oscillation), and dressing cycles, often achieving double-digit percent improvements in Overall Equipment Effectiveness (OEE).
Wheel Configuration and Machine Compatibility
Tyrolit provides wheels for vertical spindle rotary carrier machines and horizontal spindle through-feed machines. Continuous rim wheels are used when maximum surface contact area is needed and coolant can be effectively delivered. Segmented wheels with radial slots are used for high stock removal where heat dissipation is critical. Button wheels offer a combination of high pressure per button and massive coolant flow, ideal for rough grinding of sintered parts. The wheel diameter, segment shape, and bolt pattern are custom-machined to the machine’s chuck design. Tyrolit also supplies the full set of opposing matched wheels, ground and balanced as a pair, to ensure they wear symmetrically.
