Machine Controls


Corp. (Schaumburg, IL) at IMTS introduced to North America its new TNC 640, a new dual-function milling and turning con- trol that boasts a host of advanced features for programming complex mill/turn equipment. “It’s becoming a more prevalent trend in machine tools, saving money and time on fi xturing and multiple setups,” said Chris Weber, national sales man- ager, Machine Tool Division, Heidenhain Corp., of multitasking mill/turn machines. “We wanted to take to market a very stable product. Not a lot of people are aware but we do make quite a number of turning controls. So the question was adapting turning cycles into the milling hardware platform, consolidating everything and making a seamless integration.”


Interactive CNC Programming Heidenhain’s TNC 640 was designed from the start as a dual-function control capable of milling and turning, Weber said, either at the CNC or by using off-line programming, depending on part complexity. “It’s specifi c to purpose. There


are a lot of dedicated machining controls,” Weber said. “We have a lot of user cycles on both the milling and turning side in the 640. I don’t think anybody realistically is ever going to program fi ve-axis [parts] at the machine. But you want the ability to edit the program, make changes, and visualize the part through interactive programming graphics and graphical dry runs. We have the mechanism to do interactive program- ming on the shop fl oor via cycles; they’re there for a reason.” Today’s CNCs offer substantially more software content


than in years past, as control developers offer features that help speed precision machining, improving ease-of-use as well as part fi nishes and overall productivity. “In terms of functionality and overall capabilities, it has increased incred- ibly so,” Weber said of programming directly at the control. “As parts become more complex, and as machines and operations become more complex, new software routines and subroutines are developed to enhance and complement these capabilities.”


Word on the street is our new ProfitMilling cycle drives toolpath that reduces cycle time by 75% and increases tool life by an average of 500%.


All this and more! – built for 2½, 3, 4, and 5-axis roughing cycles.
