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. ...
Graff-Pinkert's Wickman mechanic Greg Buenrostro demonstrates some basic principles for running a Wickman 1-3/4" 6-spindle.
The following is some basic information for people interested in Hydromats or other rotary transfer machines:
Rotary transfer machines are ideal for even larger quantities and more complicated parts than those produced on multi-spindles. Rotary transfer machines are used to produce turned parts which require many operations such as cross drilling, cross tapping, milling, and extensive back-working. The machines normally are used to produce volumes in the millions annually. Some of the most popular rotary transfer machines worldwide include Hydromat, Eubama, Micron, and Buffoli.
The dilemma of the lonely machine tool dealer is the common denominator of most businesses and occupations. The clients want to buy something tailored to their needs. The seller wants to sell them what they have, at a premium price. The tug of war today is over the cost of the tailoring.
We know that many manufacturers in the turned-parts community have been devastated by Hurricane Sandy. Graff-Pinkert is offering its knowledge of America's supplier base to match up companies who are hobbled by the storm with shops who have extra capacity. Call us and ask for Lloyd if you are down from the disaster. He's a good matchmaker and the fee is gratis.

We are trying to run a variety of very small parts on a 20 mm gang tool CNC Swiss and are having trouble with deflection when cross drilling and milling. Is there a way to get the live tools closer to the guide bushing?
Lloyd Graff recently purchased Jim Graff’s interest in Graff Pinkert & Co., and he felt it was time for a redo of the company’s Website and logo. Today’s Machining World, our Web magazine about the precision machining industry, also changed its logo five years ago and redesigned its Website last year. Its important to stay current in business, and periodically refreshing marketing and advertising is a way to do it. I was in charge of coming up with the logo and it was a tough gig because we really had no idea what we wanted.
