SPAZ tooth-flank grinding spindles are spindles of highest precision, fitted with high-speed resp. hybrid spindle bearings of tolerance class ABEC 9. The spindle units are driven by Poly-V-blet drive.

They fulfil specific requirements:

• Zero clearance
• Deviation of radial runout and face runout 0,001 mm
• High radial and axial stiffness
• Minimized excessive temperature rise and minimized shaft elongation in action

SPAZ spindles are provided for high-speed machining. They are used especially where a large number of different bores have to be ground with high precision, particularly when it is still uneconomic to buy an assortment of electric grinding spindles.
