Rubber and cork Centerless wheels for lapping

The rubber-cork grinding wheels for lapping are very suitable for working on centerless machines, in SUPERFINISHING operations. They can remove up to 0.01 mm. and allow to obtain an excellent finish degree. In the more tender specification, where there is a greater quantity of cork, the grinding wheel only lowers the crests of the previous grinding operation, without causing variations in diameter and shape to the piece. The obtainable roughness ranges from 0.10 to 0.03 microns Ra.

The choice is due to the physical peculiarities of the two materials. The RUBBER, with binding functions, has excellent resilience qualities and allows to obtain the self-dressing effect. CORK, with the function of cushioning the abrasive grain, has excellent polishing qualities. Rubber and cork together with the fillers contained in the dough make it possible to obtain a VERY VERSATILE tool from the point of view of applications. In fact, the same type of grinding wheel allows to grind DIFFERENT MATERIALS such as treated and untreated steel, aluminum, hardened and non-hardened stainless steel, chromium, p.v.c., glass and ceramic coatings. Obviously, the performances obtainable vary from case to case. The rubber-cork binder generates a self-dressing effect of the tool that allows to obtain excellent surface quality.

RUBBER = REPEATABILITY AND CONSTANCE OVER TIME

The high standard of the production cycle guaranteed through a careful selection of the raw material and the continuous checks during the process allow a high repeatability in compliance with the strict construction tolerances. Over the years we have also developed different binders that better suit every single application.
