the lubricant channels 10 and also of the branch channels 14 and the discharge openings 13 can be coordinated with one another so that with a specified viscosity of the lubricant at room temperature practically no lubricant is pressed out of the branch channels 14 only when the system heats up during the cutting process i e when the viscosity of the lubricant decreases does the lubricant become less viscous and lubricant can then be transported outward through the branch channels 14 the compression piston 17 is penetrated by a filling channel 21 in which filling channel 21 there is a ball valve the ball valve can be pressurized in the closing direction by a compression spring 22 the closing element of this ball valve namely a closing ball 23 is preferably pushed by the spring 22 against a valve seat which surrounds a filling opening 24 the dispenser 9 can thereby be closed for refilling a hollow needle can be introduced into the filling opening 24 by means of an insertion opening 25 in the cover plate 20 and the closing ball 23 can thereby be raised from its seat in this manner the dispenser 9 can be refilled with lubricant in another possible embodiment of the present invention the dispenser 9 can be refilled by removing the cover plate 20 after the.
