The GL4i - SWITCH is the versatile universal grinding machine with a manually adjustable wheel-head for straight and angular applications. The switch series features allows switching between three patterns of straight, angular 45 degrees and angular 60 degrees swivel, providing more thrust on the wheel diameter during face grind, faster cycle times and reduced probability of burning on face grinds.
