Surface Treatment - Grinding

The DCC-Z500 Masonry Block Grinder is a heavy- duty machine designed for high production face grinding of CMU’s using “Di-Coated” Diamond Drums and / or vertical spindle wheels. The modular grinding station setup offers the rapid stock removal of diamond drums and the excellent finish of a vertical spindle diamond disc.  Sequential power-up of motors helps cut power cost and prevents power surge.
