3A1 / 1A1-CB CBN Wheels

3A1 / 1A1-CB CBN Wheels Resin Bond– High-Precision Grinding for Hardened Steels | Braemar USA

3A1 / 1A1-CB CBN Resin Bond Wheels are engineered for high-accuracy grinding of hardened steels, high-alloy tool steels, bearing steels, and HSS materials. Built using premium cubic boron nitride, a controlled resin bonding system, and precise wheel geometry, these wheels deliver fast cutting, cooler grinding, and superior surface integrity in demanding production environments.

Ideal for CNC tool grinding, surface grinding, OD/ID grinding, and fine-finish applications, Braemar’s resin bond CBN wheels provide a consistent, predictable grinding action that enhances tool accuracy, reduces thermal damage, and extends wheel life.

High-Performance Resin Bond System

The advanced Braemar resin bond matrix ensures:

Cool-cutting performance with low grinding forces
Self-sharpening behavior through controlled bond breakdown
Stable geometry retention for tight-tolerance operations
Reduced burn, thermal cracks, and distortion on hardened steels

The bond exposes new, sharp CBN grains as the wheel wears, maintaining aggressive cutting without sacrificing surface quality.

3A1 & 1A1-CB CBN Wheel Advantages

3A1 – Precision Flared Cup CBN Wheel

Excellent for tool grinding and detail geometry work
Superior edge accessibility
Stable rim structure for high-accuracy grinding

1A1-CB – Straight Wheel with Continuous Rim

Wide contact surface for stable, uniform grinding
Ideal for cylindrical, surface, and OD/ID grinding
High stock-removal capability with fine finish options

Engineered for Hardened Steel Applications

Braemar resin bond CBN wheels excel when grinding:

High-Speed Steel (HSS)
M2, M35, M42 cobalt steels
A2, D2, S7 cold & hot-work tool steels
52100 bearing steel
Powder-metal steels
Die steels & high-alloy metals
Nickel-based alloys

Because CBN does not react with iron, it is the correct abrasive for all ferrous tool-steel grinding applications.

Consistent Precision for Advanced Grinding Systems

Designed for:

CNC tool grinders
Surface grinders
Cylindrical / OD / ID grinders
Tool-room grinding
Automated high-volume production

Braemar’s manufacturing precision ensures balanced wheels, accurate arbor fitment, and uniform diamond/CBN distribution for long, trouble-free performance.
