Eight-axis CNC turn/mill machines—EMCO Maier, booth A-8540 - Turning Equipment - advertisement - Brief Article

The Hyperturn 645/665MCplus, an eight-axis CNC turning-milling machine with Y and B axes is said to feature an crgonomically designed work area with straight chip drop, fully covered guideways and optimum lighting. According to the company, both dynamic spindles are powered by integrated spindle motors with synchronization and have a wide speed range, high torque and high drive power. The main spindle also has a bar capacity with a maximum diameter of 45/65 mm. The 12-station, upper tool turret Y axis and B axis (Quickmill or Powermill) have 12 driven tools and are for use on both spindles. The lower tool turret, which is also used on both spindles, features VDI quick-change system, 12 driven tools and alignment-free toolholders. The machine's control is a Sinumerik 840D with LCD color monitor.

This B-axis configuration of the Hyperturn QuickMill allows the upper turret to swivel to any position within a 45-degree arc. The combination of axial holder, radial holder and 45-degree holder can reach any angle within a 180-degree range. Its tool-change time is 0.14 second.In the configuration of the Hyperturn Powermill, a milling spindle with hollow-shaft motor takes the place of the upper turret. The B axis travels 210 degrees. The tool carrier is a 24-tool station magazine with Capto-C4 holders (48-tool stations optional). The Y axis of the machine is designed to divide the cutting forces over two guide planes. The result, the company says, is rigidity for all turning and milling operations. Travel of [+ or -]50 mm permits off-center milling and drilling. The company will show examples of its machine tool line. Some additional models on display include the Hyperturn 690 and Emcoturn 325-II.
