Attention to mounting ”S-Head for aluminum alloy” SMAL type
When mounting head to shank, tighten with recommended tightening torque value not to be over-tightening.

■NOTE 2) It is important for grasping the shank to defend and keep proper grasping length. 3) In case of ramping, reduce 30-60% of above data. 4) The figures to be adjusted according to machining shape, rigidity of machine and work clamping. 5) If machine does not have enough spindle speed, recommend to reduce the feed speed to the same ratio. B188 6) Spindle speed shall not exceed recommended cutting conditions.
