Main spindles for turning, milling, boring, boring and milling machines

Aerostatic CNC Tool spindle "ASD-PH63M"

About the "ASD-PH63M"
  • Ultraprecise accuracies & Rotational scatter better than 15 nm (Error-Motion) 
  • The highest spindle stiffnesses and load capacities for aerostatic work spindles on the market 
  • A constant torque of 13 Nm and a speed up to 12,000 rpm
  • Possesses a manual HSK-A63 tool clamping system
Due to its high rotational fidelity and synchronous running, our ASD-PH63M is very popular as a grinding spindle and with its application in the production of glass lenses. The so-called "sub-surface" damage to the substrate during the grinding process and the subsequent polishing time have been significantly reduced. Due to the consistent symmetrical design and a highly efficient thin-film liquid cooling system, the wave growth from the cold state and standstill to the heated-through state, with a heat-through time of less than 8 minutes, is less than 1 µm at 10,000 rpm. The slim cartridge design allows use in horizontal and vertical machining centers with a closed headstock. The high-performance motor option with a constant torque of 13.5 Nm and high rotational fidelity also makes our ASD-PH63M suitable as a tool spindle for holding large grinding wheels.

As a result, the user in ultra-precision and CNC machining gets a thermally stable solution for generating optical components or for high-precision positioning in axis mode.

Our spindle is also available as a workpiece spindle (ASD-Px).

Workpiece spindle "ASD-Px"
About "ASD-Px"
  • Workpiece motor spindle for turning, fly cutting & positioning 
  • It can function as a turning spindle (with variable workpiece clamping) or be used for accurate workpiece angle positioning 
  • Speeds up to 12,000 rpm while maintaining the highest rigidity on the market 
  • Stable machining (rotational fidelity or error motion < 15 nm) of large, heavy components & small lenses
Our ASD-Px, used for workpiece rotation and orientation, combines ultra-precise accuracies with rotational fidelity (error motion) better than 15 nm, along with the market's highest spindle stiffnesses and load capacities. Due to the consistent symmetrical design and a highly efficient thin-film liquid cooling system, the shaft growth from the cold state and standstill to the heated-through state at 10,000 rpm is less than 1 µm (with a heat-through time of less than 8 minutes).

As a result, the user in ultra-precision machining gets a spindle solution for all concerns of workpiece rotation. These include, on the one hand, the machining of particularly large workpieces at low speeds, particularly small workpieces at high speeds, and, last but not least, precise orientation in axis mode. 

About the workpiece clamping

The chuck interface consists of a ground faceplate with a diameter of 120 mm and a standardized hole circle pattern. Own or commercially available rotary workpiece clamping devices can be attached to this.

Our spindle is also available as a tool motor spindle to accommodate large grinding wheels (ASD-PH63M).
