When you’re machining precision parts at high speed and feed rates, holding tight tolerances of +/-.001 in. (.025 mm) is critical.
That’s why Camcor Industries, Carp, ON, invested in the Fanuc T21i-Fla RoboDrill for its milling operations.
The 16,000 sq ft machine shop offers three, four and five axis precision machining of 2D and 3D complex geometries. It specializes in the high tech manufacturing sector (e.g. avionics, telecommunications, medical and scientific devices) and while it’s a niche market, it’s still a competitive one. So when Camcor installed the RoboDrill in February 2011, the company was looking to also reduce cycle times and improve machining productivity.
“We’ve cut cycle times in half compared to a 10,000 rpm machine we were using. We also have a low scrap rate through the 4th axis and no backlash [no loose movement on each axis of the table due to the servo motors and the Fanuc control]” says Robert Brinker, operations manager.
Camcor selected the RoboDrill because the price point was right, but more importantly, Brinker says he likes the reliability of the machine. The machine was purchased from Legere Industrial Supplies Ltd., Ottawa, ON, a Canadian distributor for Methods Machine Tools Inc., the exclusive North American sales, service and training source for Fanuc.
“We haven’t had a service call yet; it’s a reliable machine. It has a fast tool changer, and fast table speed, and a simply designed coolant supply. The Fanuc 31i-A5 control is perfectly integrated and tuned with the machine.”
Method’s now offers the new generation RoboDrill, the Fanuc D21. It features a new 31iB control for high speed processing, as well as troubleshooting and maintenance capabilities. It allows users to receive notifications if any of the drives or electronics requires adjustments. The machine is available in three sizes (small, medium and large) with a 14 or optional 21-tool tool changer. It features accelerations in X, Y and Z axes to 1.5 g, rapid traverse rates of 2,125 ipm and feed rates to 1181 ipm (2,362 ipm optional).
Camcor is an ISO 9001:2008 certified manufacturing business formed in 1992 by brothers Roberto and Orlando Campagna. In addition to machining, it offers secondary services--welding, electron beam welding and assembly.
