Servo-controlled dual-blade shear cut-off
HAVEN Manufacturing’s flagship
machine – the Model #873 dual-blade
shear cut-off – has been installed at a
Tennessee, USA-based manufacturer of
high quality tubular products for furniture
and other related industries.
The primary application will be for
mattress foundations – an assembly
made from 1" square tube lengths.
Oddello Industries has been able to
develop a fully programmable process,
which couples a piercing operation
– supplied by another manufacturing
partner – with a Haven servo-controlled
dual-blade shear cut-off machine. The
resulting process has proven able to
process nearly 15 miles of tube per
day into 38 unique parts (SKUs) within
length tolerances that never exceed
0.0015".
This collaboration was proven so
successful that the customer has made
plans to expand its operation further.
The original Haven machine efficiency
resulted in an immediate second order
of the servo dual-blade shear cut-off
machine to handle increased demand
from a number of new customers.
The Haven machine is capable of
cutting tube from square or round stock,
in lengths from 2" up to any customer-
specified length, and employs a
programmable closed-loop servo drive
to ensure accuracy. Haven prides itself
on a robust steel construction and
quick-change features for its entire
line of cut-off machines and related
equipment.
