Tool Holding Systems Shrink Fit Chuck HSK80A DIN69893 with High
Dynamic Balance Accuracy 25000 r/min G2.5
Feature Advantage:
- Different lengths to meet a variety of needs.
- High dynamic balance accuracy, 25000 r/min, G2.5, can achieve super
finishing milling.
- 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.
- Use a heat shrink machine to heat and quickly load and unload
tools. High rigidity. High clamping force.
- 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 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 chuck body has high strength and reliable clamping force. 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.
Technical Information:
- HSK vacuum shank with a taper of 1:10.
- 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.
- 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.
- 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.
- 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.
- HSK tooling systems are widely used in aerospace, automotive, fine
mold and other manufacturing industries.
