  • Tool spindle for a device for fine machining of optically active surfaces on workpieces
    Patent number: 11426837
    Abstract: The invention relates to a tool spindle for a device for fine machining optically active surfaces on workpieces, having a spindle housing and a tool holding portion which protrudes beyond the housing. The tool holding portion can be axially advanced towards the workpiece along a tool rotational axis via a guiding assembly, which can be rotated about the tool rotational axis in the spindle housing. In order to axially advance the tool holding portion, the guide assembly has a plurality of linear mounting elements, which are distributed about the tool rotational axis in a uniform manner, and respective paired guide rods, which are connected to the tool holding portion in a traction- and pressure-resistant manner.
