Zr (Zirconium) is the type of abrasive grain suitable for coarse to medium particle size applications on metal, making it an excellent choice for demanding applications, for example on stainless steel. It works best under high pressure, which is necessary for the grain to break, exposing new sharp edges. It is a type of abrasive that has large fracture planes and self-sharpens during the cut.
Stronger and relatively rigid compared to J cloth , X cloth is used in products designed for medium and coarse grains and material removal and finishing applications. It is one of the standard Cloths used by all manufacturers.
Stronger and more resistant to breaking and cutting, the Y cloth is a support used in products designed for severe applications, usually in belts. It is usually made of polyester to ensure greater mechanical resistance.
The indicated grits are the most common for the operations in question, but they do not exhaust all available alternatives. We will be happy to help you find the best solution for your case.
The indicated diameters are the most common in the industry. OTA has many more dimensions available, as it produces formats tailored to the needs of its customers.
Disc holes is an important and often neglected topic. The best solution depends on several factors, namely: the disc diameter, the suction system and the holes in the disc pad. Therefore, there is a huge variety of standard solutions.
The backing of the abrasive in fabric (Vel) is the most common application in Europe and is designed to allow the use of discs or sheets on equipment or plates with a Velcro® type system to allow easy, quick and reusable fastening. The type of fabric is always adjusted to the abrasive in question and comes in a wide range of weights and strengths.
The self-adhesive solution with a double-sided film on the back of the abrasive (SK) is intended for specific applications that are very demanding in terms of adhesion or support. Adhesion and thermal resistance are important variables and OTA has several alternatives available. It is typically used in rolls, discs and sheets.
It also exists an Ad (self-adhesive) fixing.
