Koepfer America LLC will display four machines at IMTS: 1.) its Model 300 CNC hobber, 2.) Wenzel GearTec's Smart Gear inspection and CMM machine, 3.) Wenzel's WGT350 gear inspection machine, and 4.) Monnier + Zahner's Model MZ130 CNC fine-pitch hobber. Koepfer's Model 300 is a nine-axis, heavy-duty machine able to hob gears with maximum modules of 4 mm. The CNC hobber can also skive gears and perform diagonal hobbing. Moreover, it has a timing-to-part feature. Gimpert says this feature allows the Model 300 to easily perform difficult operations, such as aligning a gear tooth to a hole or slot in a helical steering pinion. The Model 300 features direct-driven workpiece and cutter spindles. The workpiece spindle has a maximum speed of 800 rpm, while the cutter spindle's speed ranges from 200-2,000 rpm or alternatively from 400-4,000 rpm.
