1A1 CBN Wheels
1A1 CBN Wheels are engineered for precision grinding of hardened steels, high-alloy tool steels, and ferrous materials where heat control, surface finish, and edge integrity are critical. The 1A1 flat-profile wheel design delivers exceptional rigidity and stability, making it ideal for surface grinding, cylindrical grinding, OD/ID grinding, and high-accuracy tool manufacturing.
Built using premium synthetic CBN abrasives and advanced resin bond systems, these wheels provide a fast, cool-cutting action that maintains sharp cutting edges throughout the wheel’s life. Braemar USA’s resin matrix is formulated for controlled breakdown—continuously exposing fresh CBN grains for consistent performance, reduced heat, and superior surface quality.
Key Features & Advantages
1. Superior Grinding Performance on Hardened Steels
CBN is the optimal abrasive for ferrous materials because it will not chemically react with iron.
Braemar 1A1 CBN wheels excel in grinding:
High-speed steel (HSS)
M2, M35, M42 cobalt steels
Tool steels (D2, A2, S7, O1)
Powder-metal steels
Spray Materials
Bearing steels (52100)
Heat-treated alloy steels
Nickel-based alloys
2. Cool-Cutting Resin Bond Technology
Braemar’s resin system reduces grinding forces and minimizes thermal damage:
Lower heat generation
Reduced burning and micro-cracking
Improved edge retention
Stable, smooth grinding action
3. Excellent Surface Finish & Geometry Retention
The controlled bond structure provides:
Fine, consistent surface finishes
Reduced wheel loading
Minimal chatter
Accurate part geometry and dimensional stability
4. Long Wheel Life with Predictable Wear
Our premium resin formulations ensure:
High CBN retention
Self-sharpening performance
Reduced downtime
Stable performance in long production runs
