Ultra-Precision Work-Holding Motor Spindle “ASD-Px”

Our ultra-precision, high-load workpiece spindle ASD-Px is used to hold, position, and/ or rotate workpieces during the machining process, typically in turning, milling, and grinding applications. It combines the highest precision and spindle errors (DIN-ISO230-7, Error-Motion) of less than 12 nm with industry-leading stiffness and load capacity values. Thanks to its symmetrical design and efficient thin-film liquid cooling, shaft growth is proven to be under 1 micron, at a soak-time of under 9 minutes. To give ultra-low vibration levels it accommodates our in-house developed iron-less BLDC motor technology with 6.5 Nm (S1/100%) torque as a standard. But if your application requires it, a high-torque motor version with 20 Nm (S1/100%) is also available.

Our ASD-Px provides a comprehensive spindle solution for workpiece rotation and positioning in ultra-precise applications. It is design to handle both, large workpieces at low speeds and small workpieces at high speeds. Along with high-resolution rotary encoder systems, it also gives you angular positioning accuracies of under 1″.

A secure, but not tight work-holding is crucial for the precision and quality of the machining process. Depending on the type of workpieces and the machine used, various work-holding methods and fixtures are available.

The same applies to the spindle housing. Whether it’s the spindle cartridge itself, a cross-table mount, a carbon-fibre sleeve or a flanged steel housing. All are available, and we will make sure you get the right one to accommodate our ASD-Px also in your machining solution.
