Mr. Eichisky, president and general director of SIB, says: "Considering
the batches sizes, the product life, the working conditions, we have
successfully chosen the solution of the single or double bar transfer
machine". "Comparatively, a transfer machine, in
average, is equivalent to about four mechanical multi-spindle lathes.
This is extremely important, if one thinks that the financial investment
is practically the same as the investment of a modern multi-spindle
lathe", M. Eichisky, who has carefully evaluated the choice,
says.
The chosen solution drastically enforces the company competitiveness,
taking into consideration the small margins, but also the investment
capacity and mainly the area aspect that, like for many companies,
is an unproductive factor and an additional cost to be added to the
sale price. But it does not finish here; the dead times, such
as part change-over, have been practically reduced by one third in
comparison with the existing machines. The return of the invested
capital is then considerably faster, taking into consideration all
these productivity factors.
"On the other hand, M. Kieffer, in charge of the engineering
methods department, says, it is not to be neglected the rotating tool
factor, allowing a better adaptability to the cutting conditions,
without forgetting the operator utilisation comfort, especially as
far as the noise factor is concerned". The quality of the machining
is optimal due to the independence of the working stations, to the
perfect coaxial clamping of the parts and to the possibility of working
4 or more faces of the part. Similarly the transfer machines can work
producing 1, 2 or 4 parts per cycle.
Through a CNC optimised for the turning operations, the operators
learn to operate the machine at an elevated pace. "We were operative
in a surprisingly short time, thanks to quick and effective
training that has no equals in traditional training", M. Eichisky
confirms.
