Turn

Turning is among the oldest and most important machining processes – and remains the backbone of any precision manufacturing of rotationally symmetrical components.

During turning, the workpiece rotates about its own axis while a stationary cutting tool is fed in a defined manner. At the point of contact, the cutting edge removes material in the form of chips, thereby producing the desired contour. The machining process can be precisely controlled via the depth of cut, feed rate and rotational speed.

What turning is used for

All workpieces with a rotationally symmetric basic shape are turned – from shafts, axles and bolts to bushes and sleeves, as well as complex precision components with internal contours, threads and undercuts. Modern turn-mill centres combine turning and milling in a single setup, enabling even demanding geometries to be manufactured in one pass.

Precision through modern CNC technology

The machinery ranges from CNC sliding head lathes for delicate microscopic parts to fixed head and chuck turning centres for larger diameters. Driven tools, multiple turrets and automatic loading and unloading enable a high degree of manufacturing integration while maintaining consistent quality – even across larger production runs.

• Rotationally symmetrical components with tight diameter and length tolerances
• internal and external threads, undercut reliefs, grooves and complex contours
• Complete machining in the turn-mill centre – fewer clampings, greater accuracy
• Hard turning as an economical alternative to grinding for hardened materials
