About the "ASD-H20A/ UASD-H20A
with axial (A) oriented spindle connections

• Highest speeds up to 150,000 rpm for fully automtaed machining of small and integral compontens. 
• Developed primarily for the production of integral semiconductor components and optoelectronics components
• Also available with a high-pressure aerostatic bearing system (HASD-H20A) 
• Features an automatic and springless HSK-E20 tool interface 

The highest speed, precision, stability, and full automation are combined in our new tool spindle (U)ASD-H20A. It has been specially developed to meet the long outstanding requirements for producing integral semiconductor devices and optoelectronic components. Like its big sister (UASD-H25A), our new spindle model is a high-pressure aerostatic (UASD-H20A). Here, the load capacity and robustness are tripled, especially at low speeds and with larger tools.

By using our springless, patented HSK clamping system SLH-x in size HSK-20, a consistent optimization of the shaft dynamics and the highly efficient and symmetrical thin-film liquid cooling, our ASD-H20A, to the previous solutions, also offers an unrivaled dynamic or thermal stability. In addition to this stability, our customers can simultaneously expect highly dynamic machining of small and integral components. This is because of our manufacturing expertise, which we use for our ultra-precise spindle models, and our patented bearing technology.

About the "ASD-H25(A)/ UASD-H25(A)"
with radial or axial (A) oriented spindle connections

• High speeds for micromachining up to 90,000 rpm
  
• Low Error Motion values for machining optical components
• Also available with a high-pressure aerostatic bearing system (UASD-H25) 
• Features an automatic and springless HSK-E25 tool interface

Our ASD-H25(A) (aerostatic) and UASD-H25(A) (high-pressure aerostatic) models meet all the requirements of a high-quality spindle for producing optical quality surfaces with the highest accuracies. They combine the robustness and functionality of multi-axis CNC machining with high speeds for micromachining and the lowest error motion values for machining optical components. Our tool motor spindles feature a high-resolution rotary encoder and high-efficiency thin-film liquid cooling, among other features. They also feature clamping condition monitoring and a standardized housing diameter of 100 mm.

As a result, users in CNC machining get unprecedented precision, thermal stability, and the ability to machine optical surfaces in milling and grinding applications. In contrast, in ultra-precision machining, the user gets high chip removal and automated tool change for a significant increase in productivity and automation.

About the "UASD-H40A"
with axial (A) orientied spindle connections 

• A radial/ axial load capacity on the tool of up to 400 kg 
• The first full-range tool spindle for roughing and high-speed machining
• Roughing with a 10 mm tool in steel and a speed of up to 60,000 rpm
• Features an automatic and springless HSK-E40 tool interfaces 

Our full-range tool spindle allows the end user to machine precision dies on a single machine while ensuring an optical surface finish. Our patented high-pressure aerostatic bearing system allows radial and axial load capacity on the tool up to 400 kg. The UASD-H40A also features an in-house developed HSK-E40 springless tool clamping system and lists a proprietary developed aerostatic rotary feedthrough that can generate any gas or fluid pressure up to 80 bar.

Compared to hydrostatic tool spindles, our UASD-H40A offers the following advantages:
Equal load capacities and significant cost savings in energy requirements (despite 50% higher maximum speeds) for peripherals and service. In addition, the spindle records an extremely compact and maintenance-friendly design due to the much simpler sealing technology.

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).

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).
