3. Bimu specialist application : Use of VPGT in
secondary (i.e. ‚back‘) operation
In most cases, sliding headstock machines do not
offer much by way of secondary operation turning.
To redress this shortcoming, alongside its traditional
range of square-section tool holders, Bimu offers a
wide range of ‚bars‘ which enable the VPGT insert
to be used for secondary operation turning. These
‚bars‘ come in diameters of 16 mm, 22 mm, 3/4“
and 5/8“, and constitute a feasible solution for this
kind of machining work.
4. Surface treatment is a highly important process
Although the use of uncoated VPGT inserts is advisable
when machining titanium components such as
medical screws or other implants, when working
with harder materials, it does become necessary to
use inserts with a surface treatment.
For this reason, Bimu is offering its new ‘BI40U’
coating. This single-layer AlTiN coating has unusually
high surface hardness, very low thermal transfer
levels and great resistance to oxidation. It therefore
constitutes a very valuable alloy for use in turning
operations.
5. Quality at a price
Quality always comes at a price, and this VPGT product
is no exception to that rule. However, in this case,
the price really benefits the user ! In other words,
Bimu has invested the necessary effort to come up
with a high-quality insert which can rival that of any
competitor, but does so at a price that no other provider
can compete with.
If you are tempted to run a trial with the VPGT insert,
do not hesitate to contact us. You will also find a
catalogue which provides more information on our
website at www.bimu.ch.
