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.

A Hydromat Just How You Want It

Graff-Pinkert just got in two Hydromats, an HB45-12 bar machine, HB45-12 Chucker, and an HW25-12 bar machine! We offer hydromats with saw, bar feed and inverter, and then customers can choose from our wide selection of units to get the right configuration for their specific jobs.

It's a Wonderful Business

Yesterday was an emotional day for me. I gave out end of the year bonus checks to the employees of my used machinery company, Graff-Pinkert, holding impromptu talks with each person after delivering each envelope. I thanked each person for their contribution, asked them how they could improve next year and how I could help them. Paternalistic, very old school.

I found myself holding back my tears during some of the sessions. I scurried to an empty shop office to pull myself together — and wept.
