Actual results may vary. 3 Clamping force should never be outside the recommended range. Minimum drawbar force is the minimum clamping force divided by the Mechanical Advantage (M.A.) and must be available for the entire stroke. 4 Frictional force only (spring pack not included). May vary with lubricity condition, cleanliness, and taper interference. An additional 20% available reserve is recommended. 5 The distance between the tool face and receptacle face when lockrod is in its most forward position. 6 Point where the locking balls are making contact with the lockrod, canister, and cutting tool. The gap between the tool face and receptacle face is closed (no face contact pressure). 7 Distance from spindle face to lockrod front face when fully clamped with tool in place. Value does not include component tolerances and will tend to increase with use. For reference only. 8 Location of the lockrod when fully retracted with no tool in place. 9 High-pressure coolant assembly (see section 3.2).
