Vitrified Diamond and CBN Grinding Wheels

Vitrified bond superhard grinding wheels combine the high hardness and stability of ceramic bonds with the extreme hardness of superhard abrasives such as diamond and cubic boron nitride (CBN). These vitrified grinding wheels are pivotal in the modern manufacturing industry, where there is a growing demand for high-performance grinding tools. Owing to their unique advantages, ceramic bonded superhard grinding wheels have become indispensable in numerous industrial applications.

Vitrified Bond Diamond Grinding Wheels:

Outstanding Combination: Ceramic Bond and Diamond Abrasives

Vitrified bonded diamond grinding wheels masterfully combine the high hardness and stability of ceramic bonds with the unmatched hardness of diamond abrasives. This unique combination results in superior grinding power, maintaining lower grinding temperatures and reducing wheel wear, thus extending the wheel’s lifespan.

Unique Performance and Advantages:

Adaptability to Various Coolants: These wheels are compatible with different types of coolants, ensuring stable and efficient grinding processes.

High Precision and Shape Retention: The shape retention of the wheels is excellent, producing high-precision workpieces that meet precise machining requirements.

Excellent Chip Removal and Heat Dissipation: The vitrified diamond wheels feature a porous design that facilitates effective chip removal and heat dissipation, preventing clogging and burning of workpieces, thus ensuring high grinding quality.

Self-sharpening and Easy Dressing: These wheels exhibit good self-sharpening properties and are easy to dress, enhancing grinding efficiency and workpiece quality.

Vitrified  CBN Grinding Wheels:

 Components Features

Composed of CBN abrasives, ceramic bond, and pores, the performance of ceramic bonded CBN grinding wheels is dictated by these components. The ceramic bond provides mechanical strength by bonding the CBN abrasives, while pores facilitate chip removal, cooling, and reduce temperature, preventing clogging.

Unique Advantages of CBN Abrasives:

Compared to conventional abrasives, cubic boron nitride (CBN) offers high hardness, excellent thermal conductivity, low thermal expansion coefficient, and strong grinding capabilities. Though slightly less hard than diamond, CBN’s good thermal conductivity, heat resistance, and chemical inertness with ferrous metals and their alloys make it the abrasive of choice for machining difficult materials.

Efficient Grinding and Longevity:

CBN grinding wheels provide sharp cutting action with low grinding forces and high grinding efficiency. Their porous structure prevents workpiece surface burns and microcracks, enhancing compressive and fatigue strength. They last 50-100 times longer than conventional aluminum oxide and silicon carbide grinding wheels, with workpiece durability improving by 10%-30%.

High Strength and Impact Resistance:

These wheels exhibit high strength and good impact resistance, with linear speeds reaching over 60 m/s, significantly improving grinding efficiency.
