PURPOSE:To enable a tool to be held accurately in position even during working by supporting a spindle provided axially with a pair of flanges having magnets obliquely disposed by bearings having bearing magnets disposed obliquely to repulse the spindle. CONSTITUTION:A spindle A is provided axially with a pair of flanges 1 having shaft magnets obliquely disposed and supported in a quill 3 by bearings 2 having bearing magnets 2a disposed obliquely to repulse the shaft magnets spindle. Thus, a tool 5 can be accurately held in position not only when the tool 5 is mounted, but also when a load is applied for working, and particularly the spindle A can be accurately held on the axis of the quill 3. Thus, noises, vibration, etc. can be minimized and yet the manufacture, preservation, etc. can be easily carried out. |
