Wheel Coatings

Rubberhog Original

Rubberhog Original uses the 'SSG' coating consisting of very sharp conical teeth arranged randomly on the wheel surface. Many customers find that the random positioning of SSG teeth prevents 'tracking', assuring an excellent surface finish on critical products. The random tooth arrangement also makes SSG the best choice for grinding soft materials at relatively low speeds.

Rubberhog Extreme

Rubberhog Extreme uses the 'MCM' coating which is constructed of more precisely-shaped conical teeth arranged on the wheel in a regular pattern. MCM teeth have a more open structure, which greatly reduces heat, smoke and power consumption. This open structure minimizes chatter and wheel loading, making MCM the best choice when grinding hard materials. MCM teeth provide superior service life, which is especially noticeable in production grinding of tough and highly-filled materials.

Rubberhog Crushed Grit

While the Rubberhog SSG and MCM coatings offer the best productivity for most roller grinding applications, there are a number of rubber grinding applications where a more simple brazed carbide "Grit" coating is more effective. Wheels for cutting very narrow grooves, convex shapes, or complex profiles are often best made with a crushed Grit coating. The Rubberhog Grit coating is not damaged easily which makes it very effective for end trimming of rollers where the wheel is likely to contact the steel roller core. The crushed grit coating sizes are called out by coating size numbers similar to those used for sandpaper or "stone" wheels.
