Washkow, who’s been with Grizzly, based in Bellingham, Wash., for 27 years, knows that toolroom lathes are like the Atlas of most high-quality machine shops, and are called on to support the entire industrial facility. “Even then, the program may need to be adjusted to produce the degree of accuracy required on critical dimensions.” “A good machinist can get straight to work (on a toolroom lathe) off a simple sketch with a few critical dimensions thrown in while a CNC requires the part to be drawn and programmed first,” Washkow said. Foxx, chief engineer, showed that with a model which cost only about $1,500, electronic devices can control repetitive output electronically so as to save as much as 75 percent of the time normally required to make a standard machine part to tolerances as fine as plus or minus a fraction of one-thousandth of an inch.” A Lumbering Bruteįor all of the advantages of a CNC lathe outlined in the newspaper, for one-off repairs and replacement parts with tight-tolerance fits and finishes, the toolroom lathe makes a CNC look like a lumbering brute, said Washkow. It provides precision production cycle ontrol on a standard lathe without human aid, except in loading and unloading the machine. The article reads, “The first demonstration of a completely new method of mass production in metalworking industries was staged yesterday … (of an electronic machine) using a ‘piano-roll’ operating device made directly from blueprints. (previously part of Robert Bosch GmbH), Brooklyn. Seventy years ago, a June 1950 article in the New York Times heralded the first CNC lathe at Arma Corp., a subsidiary of American Bosch Corp. They were first made by the Egyptians, but it wasn’t until the 1800s that they had thread cutting abilities, according to historians. Lathes have been necessary for a long time. “I’ll even joke sometimes (and ask) when a CNC machine breaks what do you fix it with? It’s still a very necessary and needed machine.”
“You’ll have people who are new to the industry … and they’ll say ‘why do you have these machines? We now have CNCs’,” he recalled.
(Provided by TRAK Machine Tools–Southwestern Industries) It uses 1" (2.54-cm) tooling and supplies coolant at each tool. This eight-station turret is a new option for bigger lathes from TRAK Machine Tools–Southwestern Industries, such as the TRL 30120RX. Matt Washkow sometimes finds himself at trade shows manning the exhibit for Grizzly Industrial Inc., where he’s director of products, when an attendee brings up a question about toolroom lathes he’s heard before. More than 70 years after the first CNC lathe, toolroom models are as useful as ever
