The asynchronous motor spindle HF 80 A 20 is made for cutting and drilling in prototyping, in mould and die industry, in medical and micro industry. Materials to work on are ceramics, plastics, aluminium and steel.
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.
