Tool Holding Systems HSK32A Shrink Fit Chuck with High
Dynamic Balance Accuracy for Super Finishing Milling
Feature Advantage:
- Using the principle of thermal expansion, the shrink fit chuck can
hold the overall solid carbide tool more firmly, improve torque,
reduce minimum runout and better repeat positioning accuracy.
- High rigidity.
- High clamping force.
- High dynamic balance accuracy, 25000 r/min, G2.5, can achieve super
finishing milling.
- The chuck body has high strength and reliable clamping force.
- Use a heat shrink machine to heat and quickly load and unload
tools.
- High precision and small jitter. The tool mounting part does not
have the nut and collet required for the collet chuck, and is
simple and effective. The cold shrinking clamping is strong and
stable, and the beating precision is less than 0.003mm, which
reduces tool wear and ensures high precision during high-speed
machining.
- The handle is small and widely used. The ultra-thin apex portion
and the rich shank shape change can be widely used in high-speed
high-precision machining and deep hole machining.
- Simple and efficient, long life. Hot loading and unloading
operation, high durability, the same tool holder will not be
accurately reduced after more than 2,000 times of clamping, stable
and reliable performance and long service life.
- Different lengths to meet a variety of needs.
Technical Information:
- HSK vacuum shank with a taper of 1:10. The HSK vacuum shank is
elastically deformed by the shank, not only the 1:10 taper surface
of the shank is in contact with the 1:10 taper surface of the
machine tool spindle hole, but also the flange surface of the shank
is in close contact with the main shaft surface. The surface
contact system is superior to the 7:24 universal tool holder for
high speed machining, joint rigidity and coincidence accuracy.
- HSK tool holders are available in A-type, B-type, C-type, D-type,
E-type, F-type and other specifications. They are commonly used in
machining centers (automatic tool changers) with Type A, E and F
types.
- HSK tooling systems are widely used in aerospace, automotive, fine
mold and other manufacturing industries.
- When the hollow taper shank of the HSK holder is in full contact
with the spindle bore, the HSK shank end face has a clearance of
approximately 0.1 mm from the spindle end face.
- Under the action of the tightening mechanism, the pull rod moves,
the jaws expand, and the outer tapered surface of the jaws is
placed on the 30-degree tapered surface of the hollow cone, and the
HSK shank is moved to move, and the hollow taper shank is deformed.
- The end surface of the shank is close to the end surface of the
main shaft, so that the shank and the tapered surface and the end
surface of the main shaft are simultaneously positioned and
clamped.
