Chip Breaking Logan Clutch at Graff-Pinkert's Seminar

January 7, 2015 - 6:01pm -- Noah Graff
Last September Graff-Pinkert held a seminar at its facility in which we showcased a solution to the age old problem of long stringy chips that clog up screw machines when working with materials such as aluminum and copper. Graff-Pinkert's salesman Rex Magagnotti suggested that Logan Clutch could program an automated high/low clutch for a Wickman multi-spindle that would automatically execute intermittent cuts to break the chips. It was an adaptation of an old school approach of notching a cam that could peck drill to break chips. Logan Clutch's engineers successfully accomplished this feat and presented the product on a Wickman 1-3/4" at Graff-Pinkert's Screw Machine Innovations Seminar.
