Abstract
An arrangement for sealing a pressurized coolant system for a drawbar cylinder rod and a spindle drawbar in a machine tool utilizes a stationary mounting plate for supporting a piston plate and a drawbar cylinder rod. A pulley is mounted on the spindle for driving the spindle and a rotary seal that rotates with the spindle is mounted to the spindle. A non-rotating seal is mounted on the mounting plate. A planar sealing surface is formed by the contact between the non-rotating seal and the rotary seal, whereby a reliable fluid seal is formed between the rotating and the non-rotating structures of the pressurized coolant system.
