After clamping you
will have to dress it until the concentricity is below 0.01mm.
Some dimensions
are make-to-order. Ask before making a purchase. Offer other
specifications according to your drawing or sample.
Features
Vitrified Bond
Advantages:
Excellent self-sharpening: Abrasive grains break off naturally during use, maintaining strong cutting ability.
High thermal resistance: Ideal for high-speed, high-temperature, and long-duration grinding processes.
Superior dimensional stability: Minimal deformation, making it ideal for high-precision applications.
Easily dressable: Compatible with diamond dressers for quick and precise reshaping.
Disadvantages:
Brittle structure: More prone to cracking or damage under impact or side pressure.
Limited in complex shapes: Not suitable for extremely small or intricate forms.
Higher cost: Typically more expensive due to complex manufacturing and materials.
Resin Bond
Advantages:
Good elasticity: Adapts well to uneven surfaces and complex shapes, reducing the risk of chipping.
Smooth grinding action: Produces consistent finishes with minimal vibration.
Lower cost: More affordable and easier to produce in custom shapes and sizes.
Low grinding temperature: Reduces the risk of burning or thermal damage to the workpiece.
Disadvantages:
Faster wear: Shorter service life compared to vitrified wheels; more frequent replacement needed.
Lower heat resistance: Not suitable for continuous or heavy-duty grinding at high speeds.
Reduced dimensional accuracy: Can deform slightly under high pressure or heat.
Abrasive selection
Diamond wheels are best for non-ferrous and tough brittle materials
CBN wheels are tailored for ferrous and hardened steels.
Applications
Precision machining of carbide, ceramics, hardened steels, and bearing holes
Ideal for high-precision, high-efficiency grinding and polishing of internal bores
