3A1 / 1A1-CB CBN Wheels

Braemar USA 3A1 and 1A1-CB CBN Resin Bond Wheels are engineered for precision grinding of hardened steels, high-speed steels, bearing steels, tool steels, and other ferrous materials. Manufactured with premium cubic boron nitride (CBN) abrasive and advanced resin bond technology, these high-performance grinding wheels deliver fast stock removal, excellent surface finishes, and extended wheel life in demanding production environments.

Unlike conventional abrasive wheels, CBN grinding wheels maintain sharp cutting edges while generating less heat during operation. As a result, operators achieve tighter tolerances, improved surface integrity, and reduced thermal damage on critical components. Furthermore, the advanced resin bond system promotes a consistent cutting action throughout the wheel’s service life. Consequently, manufacturers can increase productivity while reducing downtime and tooling costs.

Advanced Resinoid Bond Technology

Braemar’s engineered resin bond matrix continuously exposes fresh CBN abrasive grains as the wheel wears. Therefore, the wheel remains free-cutting while maintaining excellent dimensional stability. In addition, the bond structure helps reduce grinding forces and improves overall process consistency. Moreover, cooler grinding temperatures help protect sensitive workpieces from heat-related damage.

Key benefits include:

Cool-cutting performance with reduced grinding forces
Self-sharpening characteristics for consistent cutting action
Reduced grinding burn and thermal cracking
Improved surface finish quality
Excellent form retention and geometry control
Longer wheel life and lower operating costs
Reduced workpiece distortion on hardened materials
3A1 CBN Hub 1/Side Wheels

The 3A1 wheel design provides excellent accessibility when grinding complex tool geometries and detailed profiles. In addition, the hub on one side offers improved visibility and greater reach during precision tool grinding operations. As a result, operators can maintain accuracy when working on intricate components.

Typical applications include:

Tool and cutter grinding
End mill manufacturing
Drill sharpening
Profile grinding
Form tool production
1A1-CB Straight CBN Wheels

The 1A1-CB continuous-rim design offers maximum stability and a larger grinding contact area. Therefore, these wheels are ideal for high-precision cylindrical, surface, OD, and ID grinding applications. Furthermore, the continuous rim promotes smoother grinding performance and improved dimensional control. As a result, manufacturers can achieve consistent quality across large production runs.

Common applications include:

Cylindrical grinding
Surface grinding
OD grinding
ID grinding
Bearing component grinding
Production grinding operations
Ideal Materials for CBN Grinding

Braemar CBN Resin Bond Wheels are specifically engineered for grinding ferrous materials. For example, they perform exceptionally well on:

High-Speed Steel (HSS)
M2, M35, and M42 cobalt steels
A2, D2, and S7 tool steels
52100 bearing steel
Powder metallurgy steels
Die steels
Hardened alloy steels
Nickel-based alloys

Because cubic boron nitride does not chemically react with iron-based materials, it delivers superior wheel life and grinding efficiency. Additionally, CBN maintains its cutting ability even when grinding extremely hard materials. Consequently, users experience longer production runs and fewer wheel changes.

Designed for Precision Manufacturing

These CBN grinding wheels are commonly used on CNC tool grinders, surface grinders, cylindrical grinders, OD and ID grinding machines, tool-room equipment, and automated production systems. Moreover, each wheel is manufactured to precise tolerances for excellent balance and reliable performance. Likewise, accurate arbor fits and uniform abrasive distribution help ensure repeatable grinding results. As a result, manufacturers benefit from improved process control and reduced scrap rates.

Custom CBN Wheel Solutions

Braemar USA also offers custom-engineered CBN grinding wheels to meet specific production requirements. Options include coarse to ultra-fine grit sizes, custom bond hardness levels, special wheel dimensions, modified 3A1 profiles, coolant-enhanced wheel structures, precision hubs, and application-specific tolerances.

Finally, whether the application involves tool grinding, bearing production, or high-precision manufacturing, Braemar USA 3A1 and 1A1-CB CBN Resin Bond Wheels provide the performance, consistency, and durability required for demanding grinding operations.
