Motor spindles Main features series 840 Powerful HF motor High bearing rigidity Preloaded spindle bearings HSK or internal taper 1:7.5 The 840 series motor spindles are powerful high speed systems with a liquid-cooled drive. We only use ceramic spindle bearings. This gives higher speeds, improved wearing characteristics and a longer service life. Concentricity, measured at the chuck, is <0.002 mm. 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 840 series Chuck For manual chucks, you can choose between a collet and an HSK. Rotational direction The collet version is suitable only for clockwise rotation. The HSK version can be operated clockwise or CCW. Lubrication Lifetime grease lubrication Motor It is driven by a liquid-cooled, variable asynchronous motor. A frequency converter is used to control the motor up to its maximum speed. The temperature is monitored by PTC thermistors in the motor winding. Cooling It is cooled using an integral cooling circuit near the motor windings. 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. Standard delivery Operating instructions, operating tools Mounting taper The tools are attached using an internal taper or a manual HSK chuck. The tools are attached using an internal taper or a manual HSK chuck.
