Graff-Pinkert - Screw Machines, Hydromats, CNCs

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.

Part II: Changing the Bearings

Part III: Installing New Spindle Bearings

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. ...
