Great Looking Wheel

Susan said “We received your wheel-Thank you! Everything looks very nice, actually beautiful, and we look forward to having it tested!”


In order to grind glass and ceramics effectively, metal bond wheels are typically selected due to their extremely abrasion resistant make up. The abrasive grinding fines that are produced while grinding ceramics and glass can prematurely erode many resin bond systems, resulting in less than optimal wheel life.

The Glass Grinding Process

grinding wheel is an essential tool when working with glass. A grinding wheel performs the same function as the teeth in a saw only on a much, much finer scale. However, instead of only having teeth on the edge, a grinding wheel has abrasive grains throughout the entire wheel.

With tens of thousands of superabrasive grains distributed throughout the entire wheel, the wheel grinds the glass away with a much smoother and precise cut. With a long wheel life and effective grinding properties, the wheels are used grind and shape glass.

Wheel Bonds Used for Glass & Ceramics Grinding

Metal bond is typically used to grind materials such as refractory ceramics in grit sizes ranging from D100 grit to D400 grit.

Resin bond can be used for harder, finer grain technical ceramics for finishing and super finishing of cutting edges with minimal chipping. Grit sizes typically range from D76 to D8.

Resin bond can also be used effectively in glass cut off operations. Resin bond is especially beneficial for very thin walled glass tubes used in the lighting and medical fields where a clean, chip free cut is desired. By using a softer bond system, it allows for constant exposure of new sharp diamond particles to ensure a clean, chip free cut.

Why Use Diamond Grinding Wheels When Cutting Glass?

Diamond is the hardest material known to man and synthetic diamond is hardest man-made material. Due to their hardness, they are used for various grinding purposes.

Every material is rated on Moh’s scale of hardness. The hardness is reference to the resistance of certain minerals to scratching. Moh’s scale uses ten minerals to determine hardness.

Diamond is rated as 10 for hardness on the scale and glass is rated 5.5. So any material that is within the range of 5.5 to 10 can be used to cut glass. Since diamond is the hardest, it offers the longest life, precise clean cut and is very durable when grinding glass of all types.

Multi Purpose Glass Cutting

Our glass grinding wheels are ideal for cutting and grinding all kinds of fragile material, includin:

  • stem wear
  • optical glass
  • mirror
  • sheet glass beveling
  • laminated glass
  • scientific glass.

Our wheels are great for expertly cutting glass tubing for lighting and medical industries where a consistently clean cut is necessary.

Grinding glass is typically done under flood coolant to help the removal of the grinding swarf and to prevent the clogging of the wheel structure.

Eagle Superabrasive Wheels for Glass & Ceramic Grinding

Glass and ceramic grinding wheels are typically made to order. We offer wheels that are designed to cut and grind the following materials:

  • Scientific Glass
  • Laminated Glass
  • Toughened Glass
  • Stem wear
  • Optical Glass
  • Mirror and Sheet
  • Al2O3
  • Si3N4
  • B4C
  • Mullite
  • ZTA
  • SiN
  • SiC
  • CMCs.

Grinding of these materials is typically done under flood coolant to aid in the removal of the grinding swarf and to help prevent loading or clogging of the wheel.

Typically our Glass Grinding Wheels are made to order. We recommend our diamond grinding wheels when working with glass, they offer precise clean cuts with an optimal life span.

We use two types of bonds with our glass grinding wheels, metal and resin bonds. Metal bond wheels are typically selected because they are extremely resistant to the grinding fines that are produced while grinding glass and ceramics. These grinding fines can erode resin bond glass grinding wheels causing shorter wheel life. Metal bonds do not suffer this issue nearly as badly as resin bonds.

We offer a variety of different wheel shapes and hardness’s with continuous rim and segmented rim designs depending upon the material being ground and machine operator preference.
