Pattern of Grinding Water Delivery

Product Lineup

Rough grinding

A combination of a high rigidity vitrified bond and a large diamond grit are employed to achieve a stable grinding process.

• VS : Standard vitrified bond wheel

Fine grinding

By using a resin bond, which causes little damage to workpieces, a stable grinding process is attained. As a result, the thickness accuracy (TTV) is improved and process quality, together with wheel life is enhanced. Also, surface roughness is reduced.

• B-K01 : Enhances grinding quality
• B-K02 : Enhances wheel life.
• B-K04 : Standard resin bond wheel
• B-K09 : Enables high-load processing

Etched wafer grinding (for wafer manufacturers)

Capable of precision grinding to planarize etched wafers.

• B-M01 : Standard resin bond wheel for grinding etched wafers

To use these DISCO blades and wheels (hereafter precision tooling) safely...
Please read carefully and follow the instructions below to prevent any accidents or injuries:

• USE a safety cover (nozzle case, cover), equipped as a standard accessory, to avoid injury.
• DO NOT EXCEED the specified rpm limit indicated on the precision tooling.
• FOLLOW the instruction manual of the equipment to mount the precision tooling properly.
• DO NOT DROP OR HIT the precision tooling. This may cause breakage or injury.
• Always CHECK the precision tooling for chipping or any other damage before starting to use it. DO NOT USE the tooling if there is any damage.
• READ the operation manual of the cutting/grinding equipment before use.
• DO NOT USE the precision tooling with modified or customized equipment.
• DO NOT USE precision tooling that has a different size from the one recommended for your equipment.
• DO NOT USE the precision tooling for any other purpose than grinding, cutting, or polishing.
• Always USE water or coolant to prevent precision tooling damage.
