With a spindle error (Error-Motion) of under 15 nm, the highest stiffness and load capacity for an aerostatic tool spindle our ASD-PH63M adds HSK-A63 tooling to Ultra-Precision spindle quality.
The ultra-low spindle error and the iron-less motor technology makes this spindle model ideal for grinding glas lenses with reduced sub-surface damages what again reduces the time required for polishing. Moreover its HSK-A63 tool interface allows a quick and repeatable wheel change.
A spindle soak time of under 9 minutes (cold and standstill to 10 krpm) and a thermal shaft growth of less than 0.8 micron are achieved by the strictly symmetrical design combined with our efficient thin-film liquid cooling technology.
The cartridge design with axial spindle connectors allows its use in horizontal as well as vertical machining centers with closed spindle stocks. The “high-Torque” option gives 14 Nm motor torque (S1) and allows to carry even large grinding wheels.
As a result the user gets an ultra-precision spindle solution for the manufacture of optical components applicable to both ultra-precision and CNC machining centers.
