Description

Motor spindles Main features series 820 Air-cooled HF motors Concentricity on the mounting taper < 0.002 mm The 820 series motor spindles are air-cooled. A frequency converter is required to operate the spindle drive up to its maximum speed. The spindle shaft and motor shaft are made as a single piece in order to ensure the best possible vibration characteristics. To manufacture these spindles, we only use selected materials that guarantee a high degree of accuracy and reliability even under extreme conditions. The technology of the 820 series Bearing We only fit high precision preloaded bearings. These have excellent attenuation properties and wearing characteristics. Concentricity measured at the chuck is < 0.002 mm. Rotational direction The anti-twist lock on the mounting taper allow our grinding spindles to be operated clockwise and CCW. This requires use of our original accessories. The collet version is suitable only for clockwise rotation. Lubrication Lifetime grease lubrication Motor It is driven by a liquid-cooled, variable induction motor. A frequency converter is used to control the motor up to its maximum speed. Seal The tool side is sealed by a specifically proven labyrinth packing. This protects the spindle bearings against soiling. Spindles can be installed either horizontally or vertically.
