Aerospace. “We had been using some hydraulic chucks
for critical operations on our other machines in the past,
but we switched to the Haimer shrinkfit toolholders after
observing the success we had in high speed machining with
the Haimer products.”
Koss Aerospace selected Haimer’s Power Clamp Economic
NG shrinkfit toolholder system and Haimer’s Tool Dynamic
toolholder balancing machine. Now in operation for more than
two years, Cajic and machinist Ljubisa Bodiroga, who works
on the high speed machines and uses the Haimer toolholder
systems, are impressed with the technology.
“I’ve never had any runout problem with this system. I like
that it holds the tools and the toolholder very secure and we
don’t have any problems,” explains Bodiroga.
The Haimer shrinkfit technology offers less than 0.00012 in.
runout at three times diameter.
Cajic says he also likes the versatility of the universal Haimer
shrinkfit unit that is designed with a flexible and modular
system. While the system is used primarily on high speed
machines, it’s also used, from time to time, on other machine
tools in the shop.
“Shrinkfit eliminates vibration and chatter, so you get
higher accuracies and because the technology holds tooling and
toolholders so securely, it eliminates a lot of potential problems
like tool breakage.”
Other advantages that Cajic and Bodiroga like are the
gripping force–the chucks can grip the cutting tool 360°
