HSK coolant tubes HSK form A holders must be equipped with a coolant tube. Using holders without a coolant tube could cause unseen machine spindle damage. The coolant tube is ideally mounted in vertical direc- tion - from the bottom to the top. In this manner the sealing ring is prevented from being compressed during location which would cause the loss of its sealing function. After mounting, the coolant pipe can be moved only to a minimum degree according to DIN (± 1°). Installation 1. The HSK holder must be clean, free of swarf and undamaged. 2. Grease the O-rings prior to assembly. 3. Centrally insert the complete coolant tube (coolant pipe, union nut and 2 O-rings) in the HSK using the appropriate socket spanner. 4. Screw in the coolant tube and tighten (see table for torque figures) 5. Check coolant pipe for radial mobility.
