Haas | Draw Bar force HELP please! Practical Machinist
The folks at Clamprite said the same thing as well. At 900lbs., it is a wonder that the tools stay in under load. Even more surprising is that 900 lbs is the spec from Haas. To address Phil, drawbar clamps the pull stud with 4 eqaullt spaced ball bearings. The draw bar, when actuated, released the pressure on the ball and releases the tool.
