All spindle parts are hardened and ground for a high spindle lifetime. Joining elements are inherently safe and force-fit with ground threads. The shaft and all rotating parts are balanced less G1 for best vibration result (< 1mm/s). The water cooling through the spindle housing up to the spindle nose guarantees a constant operating temperature. The rear ball bearing package is installed in a bearing bush for thermal compensation to the spindle end. For high axial stiffness and damping the rear bearing package and bearing bush are pre forced with springs. A concentric and axial runout less 1µm assures high process quality. Grease-packed ball bearings with close bearing cages to keep the grease at the balls. No uncontrolled maintaining necessary. Ball bearings for higher speed are either lubricated with minimum quantity oil-air lubrication or direct-bearing lubrication for less consumption and less friction. All HF or HT motors are equipped with winding protection and give highest performance with less lost effect. A motor thermistor (KTY or PTC) is standard and avoids a motor overheating. Air seal and a labyrinth seal provide a sufficient protection against dirt and humidity in the spindle.

Many optional monitoring systems for process surveillance are available.
