Wieland customer-specific units are available as spindle units, slide units, facing units and special units. The portfolio supports machining, positioning and feed motions as well as customized unit concepts for specific machining requirements.
Depending on the requirement, standard values, individual combinations and tailored solutions are available. For spindle units, 3D models can be provided on request.
| Diameter spindle bearing | Nominal width mm | Spindle head HSK mm | Max. spindle speed U/min | Max. power kW |
|---|---|---|---|---|
| SP35 | 100 | 40 | 16,000 | 2.2 |
| SP45 | 125 | 50 | 12,000 | 4 |

Wieland spindle units are available in different standard sizes. The size units given in the table are standard values, but individual combinations are also available. A 3D model can be provided on request.
Slide units are used for positioning or feed motions. Roller monorail guidance systems and electromechanical drives are preferably used. Other guidance and drive systems are designed according to requirements, including hydrostatic and hydrodynamic systems.
| Design: | 1-axis- , 2-axis-, 3-axis-units |
|---|---|
| Guide: | rolling guide, hydrodynamic or hydrostatic guide |
| Nominal width: | 125, 250, 400, 630, 800 mm |
| Nominal strokes: | 160, 250, 400, 630, 800 mm |
| Drives: | servo motor, hydraulic, pneumatic |
| Options: | linear scale, integrated built-in spindle, direct or offset drive, telescopic covers |
Machining units with facing heads on special purpose machines are used for machining rotationally symmetrical contours on components. This makes it possible to carry out machining operations such as facing, boring, plunge cutting, NC copy turning, backface machining and chamfering.
The spindle units are equipped with a cross-feed device for heavy-duty machining or a rotationally actuated system for high-precision machining.
The NC facing unit PZM transmits the actuating force via a drawbar to the tool. Thermal expansion can be compensated within the crossfeed system.
The NC facing unit RM synchronizes automatically on the spindle drive and transmits a rotatory positioning movement to the tool. This results in high precision even with high strokes and is achieved without thermal expansion.
Deviating from standard machinery, Wieland provides solutions tailored to specific machining requirements.
