Design Features and Kinematics of TDM SA Grinding Motor Spindles

Swiss manufacturer TDM SA designs high-frequency motor spindles for internal deep-hole grinding and exterior ultra-precision machining operations.

The engineering incorporates hybrid ceramic ball bearings with calibrated axial preloading, delivering dynamic rotational stability at speeds reaching 180000 rpm, continuous power up to 40 kW, and torque up to 50 Nm in continuous S1 duty.

The spindle housing with outer diameter up to 170 mm integrates closed-loop liquid cooling jackets to dissipate stator heat. Tool holding interfaces feature HSK, ISO, HJND, and HJNZ taper standards with rigid structural contact.

Internal non-contact transducers continuously monitor shaft radial runout and operating bearing temperature during machining cycles.

Dynamic Capabilities of Milling Motor Spindles and Horology Units

TDM SA milling motor spindles unite high dynamic stiffness and rapid rotational velocity for aerospace alloy machining and precision watchmaking.

Integrated synchronous and asynchronous electric drives generate power outputs up to 100 kW with continuous torque reaching 1200 Nm in prolonged S1 cycles. Ultra-compact variants developed for horology manufacturing allow spindle axis-to-axis spacing down to 55 mm on multi-spindle workstations.

Despite minimal envelope dimensions, the spindle housing integrates winding thermistors, axial thermal growth sensors, and high-resolution optical encoders for continuous monitoring and synchronization with CNC systems.

Multi-Tools Turret Spindle Assemblies for Multi-Tasking Lathes

Multi-Tools turret spindle assemblies by TDM SA expand machining center capacity by hosting 2 to 10 tooling positions on a single dynamic drive unit.

The rapid indexing mechanism completes chip-to-chip tool changes in 2 seconds without requiring carriage retracts to home positions. The spindle achieves rotational speeds up to 80000 rpm with drive power of 30 kW and torque up to 60 Nm.

Equipping turn-mill centers with Multi-Tools eliminates clamping datum accumulation errors during multi-step machining, diminishes linear guide wear, and reduces overall cycle times for intricate batch manufacturing.

Non-Contact Hydrostatic Spindles for Ultra-Precision Mirror Machining

Hydrostatic motor spindles and precision spin tables by TDM SA employ fluid film mechanics without solid mechanical friction between rotating shaft and bushing.

High hydrostatic pressure distributed across symmetrical radial pockets provides an ultra-rigid damping layer that eliminates micro-vibrations at speeds up to 250000 rpm. Absence of physical wear guarantees virtually infinite operational lifespan.

The equipment is utilized for diamond turning of copper drums, photolithography optics, and fuel injector components, delivering mirror finish roughness Ra between 1 and 2 nanometers with submicron rotational concentricity.
