Rollomatic (Mundelein, IL) maintains its global leadership position in the field of pinch and peel grinding by developing a new process. Rollomatic is the original inventor of the pinch/peel grinding methodology and stays in the forefront in developing specific processes related to making this type of machine even more productive. Pinch grinding offers accurate geometrical dimensions on the blank and eight surface finish requirements. In pinch grinding, the roughing and finishing wheels grind parts simultaneously, with the finishing wheel trailing the roughing wheel. The rough and finish grinding are performed in one pass. This innovative way to cylindrically grind parts eliminates separate processes and reduces cycle time. Rollomatic developed an advanced process known as “double rough pinch grinding” which vastly decreases cycle times for blank preparation of the following carbide cutting tools:
- T‐slot cutters
- Thread endmills
- Rotary burs
- Endmills for die and mold machining
- Long reach endmills.
