COLGAR - PRESS BRAKE
COLGAR "PI" series press brakes are the result of a long experience
that permitted to our company to put on the market rugged and reliable machines.
Peculiarity of these machines is the mechanical parallelism system with
positive stops at bottom of stroke and a tested hydraulic system assembled
with high quality components; maintenance operations are reduced to the
minimum and are of easy execution. COLGAR press brakes of this series are
suitable both for manual control of easy use and of the application of up
to dated numerical control.
PARALLELISM WITH MECHANICAL POSITIVE STOPS
positive stops inside cylinders provide for lower dead point adjustment
with high positioning accuracy and repeatibility. During down-stroke a sturdy
torsion bar provides for parallelism on small and medium-sized press brakes;a
hydro-mechanical system fulfills the requirements on large-sized press brakes.
attention is payed to cylinder manufacturing. The single components are
manufactured in order to guarantee long life and perfect accuracy to the
whole unit. The inner screw in made of special hardened steel. Threading
is particulary designed to avoid possibility of break of the screw under
load. The outside surface of piston Is hardened, ground and lapped. The
inside surface of cylinder is ground and lapped.
can be configured by combining following axes:
X-Axis - depth movement
X1, X2-Axes - depth movement on 2 independent axes
R-Axis - vertical
Z1, Z2-Axes - cross movement with independent axes
are equipped with micrometric adjustment.
to its particular precision features, the machine can be fitte with the
most appropiate fixtures according to requirements for both air bending
and bottoming operations.
