Internal Grinding & Milling Spindles
Oil-air lubricated, 9,000 to 150,000 RPM

Internal Grinding & Milling Spindles

Engineered for high-frequency operations, our internal grinding spindles run from 9,000 to 150,000 RPM across 30 configurations. Precision angular contact bearings deliver thermal stability and low vibration, from PCB micro drilling through to engine block roughing. Several models are offered with two bearing and interface options so the spindle can drop into an existing machine without reworking the mount.

External Cylindrical Grinding Spindles
Maximum rigidity, high torque

External Cylindrical Grinding Spindles

Built for maximum rigidity and high torque. Four-bearing sets in the 7011–7020 range hold micron-level accuracy under heavy loads, covering workpieces from sub-50 mm shafts through to multi-tonne rolls. All models drive through a 1:5 taper.

Workhead Spindles
Integrated hydraulic clamping

Workhead Spindles

Optimised for high-precision workpiece rotation. Integrated hydraulic clamping and high low-speed torque, for cylindrical and internal grinding from 10 mm tool shanks to 500 mm rolls. Twelve models cover 250 to 2,000 RPM, so the workhead can be matched to cycle time rather than the other way round.

Wheel Dressing Spindles
Synchronous and asynchronous drives

Wheel Dressing Spindles

Thirteen dressing spindles from 0.1 to 2.2 kW and 3,000 to 20,000 RPM. Synchronous motors hold speed under load for CBN and diamond wheels; asynchronous models cover general dressing at lower cost. Mounting diameters run from 40 to 110 mm to fit most grinder brands.

Hydrostatic Spindles with Built-in Motor
Sub-micron, roundness below 0.3 μm

Hydrostatic Spindles with Built-in Motor

Hydrostatic bearings with the motor built into the spindle. The oil film carries the shaft with no metal-to-metal contact, which is what makes sub-micron roundness repeatable shift after shift. A built-in motor removes the coupling and its alignment error, at the cost of a more involved installation than a direct-coupled unit. Requires a hydraulic power unit.

Hydrostatic Spindles with External Motor
Direct-coupled and 1:5 taper drive

Hydrostatic Spindles with External Motor

The same hydrostatic bearing technology, driven by an external motor through a direct coupling or a 1:5 taper. Keeping the motor outside the spindle body isolates its heat from the bearings, which suits continuous duty. Ten models from 5 to 30 kW. Requires a hydraulic power unit.

Supporting Equipment

Panoramic Monitoring Hydraulic Power Unit

Panoramic Monitoring Hydraulic Power Unit

Supplies and conditions the oil film for hydrostatic spindles, with full monitoring of pressure, flow and temperature across every circuit.

Spindle Chiller

Spindle Chiller

Dedicated refrigeration for motorised spindles. Holding coolant temperature stable is what keeps thermal growth — and therefore accuracy — under control through a full production shift.
