Ballscrew Whirling

Leistritz has developed a unique process solution by combining precision follower rests, an economic resharpenable tool system and high-speed whirling heads with a rigid and accurate CNC controlled machine tools. With bed lengths up to 8m, long ball screws can be whirled to finish tolerances in a single pass in full material. By clamping the finished outer diameter in carbide “V” jaws, the follower rests on either side of the cut, guaranteeing near-zero concentricity of the thread.
