CNC Twin Turret Grinder Combines Flexibility & Precision

Fives will unveil an entirely new, multi-spindle, twin-turret, high-flexibility precision OD and ID grinding system in Booth N-7018 at IMTS 2014 in Chicago, September 8-13, 2014. The new Landis Twin Turret™ (LTT) grinding machine's unique design features two rotary hydrostatic turrets with integral servo motors and X-axis hydrostatic ways with linear motor in-feed. The Landis LTT grinder can handle work pieces with a swing up to 180 mm and lengths up to 400 mm using CBN wheels up to 350 mm in diameter and 40 mm wide at wheel speeds up to 120 m/sec.

"What really makes this machine unique is the fact that we have achieved a very high level of performance in a package that uses as little as half the floorspace of a conventional grinder with similar workpiece capacity," explained Tim Hykes, Director of Technology at Cinetic Landis Corp. "Moreover, the Landis LTT is so flexible that it can perform multiple operations on shaft-type parts in a single fixturing that now typically require two or three separate machines, plus costly precision fixtures and inter-machine automation."

The Landis LTT is ergonomically designed, with a low, 1,125mm load and access height. This also makes the system easy to integrate with standard industrial robots for part loading/unloading, eliminating the need for special automation or gantry systems in many applications. Features of the new Landis LTT grinding system include automatic wheel balancers and a variety of available in-process gauges, touch probes, chucks and work drive.
