Metal-Bonded 1A1 & 12A2 CBN Grinding Wheels For Sharpening
Metal-Bonded 12A2 CBN Grinding Wheels: High-Precision Dish/Cup Wheels for HSS Tool Sharpening & Hardened Ferrous Metal Machining
The Metal-Bonded 12A2 CBN (Cubic Boron Nitride) Grinding Wheel is a dish/cup-profile wheel engineered specifically for face grinding, clearance angle grinding, and precision resharpening of high-hardness ferrous cutting tools. Featuring an angled abrasive layer on its face, the 12A2 geometry allows easy access into tight tool flutes and cutter teeth without interference. Combined with a sintered metal matrix, this wheel delivers exceptional edge retention, chatter-free cutting, and long tool life under heavy sharpening feeds.
Precise Edge Geometry & Zero Thermal Damage: Outstanding thermal conductivity dissipates grinding heat rapidly, preventing work-piece burning, micro-cracking, or annealing on cutting edges.
Superior Profile & Angle Retention: The high-strength sintered metal bond locks CBN crystals firmly, maintaining precise rake and clearance angles over long continuous sharpening runs.
High Material Removal & Smooth Chip Flow: The dish/cup structure facilitates smooth coolant penetration and efficient swarf evacuation during heavy face grinding.
Reduced Wheel Dressing & Extended Lifespan: High wear resistance eliminates frequent dressing cycles, maximizing CNC tool grinder uptime and lowering total tooling costs.

High-Speed Steel (HSS & HSS-Co): Milling cutters, drills, taps, broaches, and reamers.
Hardened Tool & Die Steels: Alloy steels hardened to HRC 45–65.
Bearing Steels & Gear Steels: Precision face plates and mechanical components.
Nitrided & Heat-Treated Components: High-wear ferrous industrial parts.
Resharpening and manufacturing of HSS end mills, reamers, and face milling inserts on universal or CNC tool grinders.
Top/face grinding and clearance angle grinding of woodworking band saw teeth and circular saw blades.
End-face precision grinding of hardened steel bushings, hydraulic valve plates, and automotive dies.
We manufacture 12A2 CBN wheels with tailored hub materials (Aluminum or Steel), custom dish angles ($U$), rim dimensions ($W/X$), and grit-bond combinations to suit leading CNC grinding machines (e.g., Walter, ANCA, Rollomatic, Vollmer, Makino). Contact our engineering team for trial wheel orders or technical consultation.
