RECERAMAX® TW is a microcrystalline sintered ceramic grain type, which was developed by RECKEL in accordance with the Seeded-Gel Technology. The very hard and tough grain has a Spaghetti-shaped profile. It can be used very well for ceramic bonded grinding wheels.

​

Under high grinding forces, the grain fractures down and creates new sharp cutting edges. This leads to a self-sharpening process. The Spaghetti profiles of the ceramic grains have a low bulk density, this creates an open structure when grinding wheels are produced.

 

The binder join the Spaghetti rods to a very stable binder/grain matrix. A porous (open) but durable structure accrues, which can withstand also high grinding pressure. The open structure ensures a very good permeability of the cooling lubricant and leads to a cool grinding.

​

In spite of high grinding forces and high metal removal rates, a material-friendly  grinding is possible. The sharp RECERAMAX® TW grain and the open structure of the grinding wheel prevents the undesired workpiece burn marks. The maximum loading temperature within the hardening process of bonded abrasives is 1430°C.

​

RECERAMAX® TW ceramic grain is offered in accordance with the market grit sizes. The grit size specification refers to the diameter of the TB ceramic grain Spaghetti rods.
