Chip Breaking Logan Clutch at Graff-Pinkert's Seminar

January 7, 2015 - 6:01pm -- Noah Graff
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

October 11, 2014 - 11:10am -- Noah Graff
Hydromat 45-12 at Graff-Pinkert

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. Why buy units you don't need, just because a machine happened to have those units? Because Graff-Pinkert is one of the few Hydromat resellers that actually stocks Hydromats at our facility, we have the flexibility to sell you a cleaned and painted machine that will arrive on your floor ready to run.

It's a Wonderful Business

December 20, 2013 - 12:18pm -- Lloyd Graff

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. Some context. As I drove to work yesterday, I was wallowing in a sense of futility.

Which Multi-Spindle Is Right For You?

In addition to CNC lathes, Hydromats and newer European multi-spindles such as Schutte, INDEX, and Euroturn, Graff-Pinkert historically has specialized in mechanical multi-spindles such as Wickmans, Acmes, and New Britains. The following is a basic guide to help you choose the best mechanical multi-spindle for you. The first question to ask when deciding which machine to buy is who is going to run the machine. If the operator is an Acme-man or a New Britain veteran who has only run those machines for decades, it's usually best to stick to the equipment which that operator knows best. However, if an operator is open to using any multi-spindle and they can run the job on a 6-spindle machine, Graff-Pinkert generally recommends using a Wickman. The main reason Graff-Pinkert recommends Wickmans is that it's a much lower cost to tool the machines. There aren’t any cams to change on Wickmans, just lever ratios. You loosen up some bolts, you slide it into the throw that you want and your done. Setting up an Acme or New Britain requires. ...
