Swarfcast Ep. 34 – Ed Crowley, Master of Insert Tooling

On today’s podcast we interviewed Ed Crowley, owner of Crowley Tool Company, a company that specializes in making custom insert form tools and quick change tooling packages for the precision machining industry. Ed explained in detail how his company has developed modular tooling that an operator can change on the fly, which can reduce set up time from days to minutes.

Chip Breaking Logan Clutch at Graff-Pinkert's Seminar

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.
