PREVENT TOOL PULL-OUT IN HIGH-PERFORMANCE MACHINING APPLICATIONS
Haimer USA offers a solution for manufacturers that push their machines to the limit.
The SafeLock System combines the advantages of a shrink-fit chuck with those of a positive connection by integrating ball or pin drivers into the chuck. Those drivers grip into helical grooves that are ground into the cutter shank in the opposite direction of the cutting forces. Because of the shape of the groove, the tool is simultaneously safeguarded against spinning as well as against pull out

Haimer USA is offering a solution for manufacturers that push their machines to the limit ? SafeLock.
The SafeLock System combines the advantages of a shrink-fit chuck with those of a positive connection by integrating ball or pin drivers into the chuck. Those drivers grip into helical grooves that are ground into the cutter shank in the opposite direction of the cutting forces. Because of the shape of the groove, the tool is simultaneously safeguarded against spinning as well as against pull out when confronted with radial and axial cutting forces.
?The clamping procedure is simple,? says Brendt Holden, president of Haimer USA. ?The chuck is heated as usual and the tool is inserted with a rotating movement. The balls or pins find their way into the grooves due to the turning movement. After a few seconds, the holder cools down, such that both a frictional and positive connection is made.?
The principal of the SafeLock System is not only limited to use in shrink-fit chucks. It can just as easily be integrated in a collet or hydraulic chuck.
