LANDIS LTT

twin turret grinder

Capture the advantages of unlimited flexibility, sub-micron precision and the ability to perform multiple operations in a single fixturing with the Landis LTT multi-spindle twin turret grinding solution. 

High performance grinding solution with one-of-a-kind capabilities

The Landis LTT is a flexible solution for grinding ID/ODs, faces, tapers, including concentric and eccentric diameters and contours, to sub-micron tolerances in a single clamping.

The two rotary turrets are equipped with integrated servomotors and X-axis hydrostatic guideways with linear in-feeds to enable simultaneous contouring of workpieces. All motors are backlash free for all motions, using ultra-stiff hydrostatic spindle bearings.
