Spindles for machine tools - Import export

Lubrication of roller and plain bearings as well as of threaded spindles, gearwheels, worms and similar components Lubrication of spindle bearings in machine tools Advantages and benefits Allows high machine service lives due to low-wear operation and low lubrication frequencies Outstanding resistance in a wide temperature range, at high stresses and surface slide speeds as well as at vibrations Resistant to cold and hot water Excellent wear protection For highest effectiveness carefully clean the lubrication point, for example with OKS 2610/OKS 2611 universal cleaner. Before filling a bearing for first time, remove anti-corrosion agent. Fill the bearing such that all functional surfaces are certain of being greased. Fill normal bearings up to about 1/3 of the free space inside the bearing, high-speed bearings (DN value above 400,000) up to about 1/4. Low-speed bearings (DN value below 50,000) and their housings should be filled completely.

The SGS (Spindle Growth System) 4701 displacement measuring system is developed for high speed milling machine applications. Due to high machining speeds and the heat generated, the linear thermal expansion of the precision machine tool spindle needs to be compensated for in order to keep the tool in a defined position at all times. The SGS sensor measures the expansion of the spindle caused by thermal and centrifugal force. The measurement takes places typically on the labyrinth-ring. As well as the linear expansion, the temperature of the sensor is detected and output.These measurement values are fed into the CNC machine tool as correction values, compensating for any positioning errors.
