Lavina S7 Grinders
Superabrasive manufactures the LAVINA range of electric and propane grinding and polishing machines.
LAVINA grinders are planetary, i.e. they are driven by belts and/or chains and pulleys with a large primary grinding head and three smaller satellite heads that hold the diamond tools. When the grinder is operating, the satellite heads rotate in the opposite direction of the main head which eliminates “rows” or linear grinding marks in the floor.
Three-head planetary grinders usually outperform other equipment on polishing jobs, because they follow the floor high and low spots better, providing a more consistent finish.
