CS 320 Y Wide belts with cloth backing for Mineral-based materials, Plastic

CS 320 Y wide belt with cloth backing for mineral materials, glass and plastic

Few other materials are similarly taxing on an abrasive as stone, plastic, glass, ceramic, crystal or concrete. Except for plastic, these materials are not particularly tough, but harder than metal. An abrasive capable of processing these materials must meet a number of requirements:

• Tear-resistant backing for high speeds
• Heat-resistant abrasive belt
• Waterproof abrasive for wet grinding
• Extremely hard and sharp abrasive grains

Why the Klingspor wide belt CS 320 Y is an excellent option for glass, ceramic or stone

The backing and, thus, the carrier for the abrasive material that has been selected for the wide belt CS 320 Y is a highly tear-resistant special cloth made of Y-polyester, which offers the added benefit of being resistant to moisture and humidity, making the belt ideal for wet grinding. This abrasive belt delivers high aggressiveness during grinding thanks to the close coating and its ability to grind at high belt speeds and great contact pressure levels. The bonding made of synthetic resin keeps the extremely hard silicon carbide abrasive grains securely and firmly in place. The combination of tear-resistant polyester, silicon carbide grain and synthetic resin bond provides all properties that are necessary to process hard materials.

Ultra hard and sharp-edged abrasive grain made of silicon carbide

Workpiece surfaces that are extremely hard - such as glass, stone or ceramic - require extra high aggressiveness and exceptional abrasive performance. These requirements call for an abrasive that is extremely sharp-edged and hard. The grain silicon carbide is one of the hardest abrasive material manufactured synthetically. It boasts the same hardness as diamond. The crystalline structure of the silicon carbide keeps the abrasive grain from being worn off, causing sections of the structure to break out completely instead. The result is another crystalline structure with a hard surface and sharp edges. This effect makes the abrasive belt CS 320 Y self-sharpening.

Wide belts by Klingspor for smooth belt operation and work with ultimate precision

Klingspor abrasive belts are designed as endless belts. To allow for smooth and clean grinding, the belts are joined in various different ways at the butt joint. A common joint is joint shape F1: The ends are cut with a bevel at a defined angle before being joined with an overlap. Belt joint F2: The grain tips are ground down, resulting in even smoother operation of the belt during grinding. Belt joints F3 G and F4 G: The belt is cut with a zigzag edge or straight bevel, and the butt joint is then supported with a fabric-reinforced tape bonded underneath.
