A perfect fit - with TER
With the
development of the patented TER shrink collet, we have been able to
revolutionize the use of collets and collet chucks in the production process.
TER ThermoGrip collets have solid bodies, unlike common, slotted ER style
collets, and are not deformed or compressed when clamping. This assures tool
Runout of less than 3 microns. The cutting tool is held more rigidly than with
standard ER slotted collets and tool length is preset prior to assembly in the
collet chuck When machining tough materials like titanium, the cutting tool
performance is significantly improved and cutting tool life will increase.
Using TER means profiting from the four main advantages of collet shrinking.
• Run-out < 3 micron
• maximum holding forces
• rigidity
• low-wear monoblock properties
This is
accomplished while using your existing collet chucks or spindles.
The short and extremely stable tool clamping with TER achieves a run-out of
< 3 micron. Tool life is considerably improved due to the precise guidance
of the tool and the ultra-precise change accuracy means that your length adjustment
is maintained even after many cycles - with optimum results.
The problem of
time consuming tool change in Swiss style machines and Live tools when holding
a cutting tool in a flexible collet is very common. Whether it is the tight
tool locations in most Swiss style machining centers or the disassembly and
reassembly of cutting tool, collet, and collet nut on live tools, down-time is
extensive and costly for many of these ER collet applications. This
non-productive downtime impacts your operating costs and increases your part
cost whether making short-run or long-run parts. The TER ThermoGrip shrink fit
collet can be used for all ER live tools and ER straight shank holders in Swiss
style machines. During the shrink fit process the cutting tool can be preset to
your required tool length in the collet. All this happens outside the machine, while
the machine continues to make parts. A tool change only takes seconds and the
machine will be back up and operating in a few short minutes because the collet
and cutting tool area single assembly now and set back into the machine in the
same tool location and gage length as the previous tool assembly was. No
concern about over torquing of the collet nut. No concern with tool point
location moving during tool change. No tool offsets and “trail part” runs to
insure part dimensional accuracy. All of the setup and tool change time
reduction will reduce the machining cost dramatically.
Using the Bilz
TER shrink fit collet and ThermoGrip system gives you the advantage of being
able to precisely adjust the length of the cutting tool in the collet during
the shrink fit process. ROI for the investment
in TER shrink fit collets and ThermoGrip machine will take less than one year
and can occur as quickly as 3 months. Available in ER16, ER20, ER25, and ER32
collet sizes with inch and metric bore sizes.
