Grinders for floor leveling and restoration. You can do many different appliions. The rotating grinding disc works horizontally, giving a far more even and flat to then be able to comfortably move the machine into tighter areas such as the corners. 4. Once started, work the grinder in a small
The grinding/machining procedure is to rotate the grinding wheel at maximum rpm, counterrotate the material to be machined at high rpm, and move the grinding wheel along the same path that the turning tool would have taken. This process is similar to turnmilling except that a grinding wheel is used instead of a milling cutter.
