Advantages
Key features
-
High rigidity and excellent shape retention
Vitrified grinding wheels offer high strength, wear resistance, thermal stability and chemical inertness. They retain their shape during grinding and provide long service life. Under the same grinding conditions, durability can reach 2-3 times that of resin-bonded wheels, with approximately twice the grinding efficiency.
-
Good self-sharpening and excellent heat dissipation
Vitrified wheels hold abrasive grains securely, wear evenly and consistently, and are easy to dress. Their relatively high porosity supports chip evacuation and heat dissipation, helping prevent workpiece burning or cracking and maintaining surface quality.
-
High grinding quality
Vitrified diamond grinding wheels generate low grinding forces and temperatures, producing high dimensional accuracy, good surface quality and good workpiece shape retention.
-
Abrasive Selection
This series of vitrified surface grinding wheels offers different abrasives to suit the workpiece:
Specifications
The range covers diameters from 150 to 900 mm, with thickness and bore size selected to suit the application. Typical specifications are listed below:

Product details
About this product
Product Introduction
Vitrified surface grinding wheels are high-performance grinding tools made with a vitrified bond through high-temperature sintering and designed for surface grinding machines. Applications include machinery manufacturing, hydraulics, bearings, molds and compressors, for surface grinding of metals and hard, difficult-to-machine materials.

4. Abrasive Selection
This series of vitrified surface grinding wheels offers different abrasives to suit the workpiece:
| Abrasive type | Suitable workpiece materials | Key features |
|---|---|---|
| White fused alumina (WA) | High-speed steel, stainless steel, hardened steel and bearing steel | High hardness, sharp edges and low grinding heat; suitable for finish grinding hardened and alloy steels |
| Brown fused alumina (A) | Carbon steel, cast iron, general steels, forgings and castings | Good toughness, impact resistance and economical cost; suitable for rough and heavy-duty grinding of common metals |
| Pink fused alumina (PA) | Cutting tools, gauges, threaded workpieces, instrument components and alloy tool steels | Hardness similar to white fused alumina with greater toughness; sharp, fracture-resistant grains produce high surface quality, particularly in form and precision grinding |
| Green silicon carbide (GC) | Cemented carbide, optical glass, ceramics, stone, semiconductors and gemstones | High hardness, friability and thermal conductivity; suitable for hard, brittle materials and resistant to loading when grinding non-ferrous metals |
| Black silicon carbide (C) | Cast iron, brass, aluminum and non-metallic materials such as rubber, leather and stone | High hardness, relatively high friability and sharp grains, with lower toughness than alumina; suitable for grinding and cutting low-strength metals and non-metals |
