adjustment is quick and simple.
Completely enclosed grinding chamber greatly reduces grinding noise, smoke, mist, fire danger, and wheel breakage hazards.
This feature eliminates the need for awkward hoods and mist collection systems.
High quality components and simplified controls help cut setup time; a complete changeover takes only 20 to 30 minutes.
Rake angle adjustment is easily accomplished by loosening a clamp and pivoting the head to the desired angle.
A calibrated dial on the workhead allows quick adjustment of the web thickness after splitting - G dimension (see illustration).
A calibrated dial on the loader quickly adjusts loading depth - W2 dimension (see illustration).
Hardened and precision ground workhead and wheelhead slides ensure years of trouble free operation.
