Linear Motors Enhance
Precision of Drawing
At Wire 2018, EJP is going to introduce the
new generation of its CDS-TQ
series of combined drawing
machines. By using a linear motor
to actuate the drawing jaws,
EJP has significantly simplified
the mechanical design and the
movements of the drawing
jaws. Thus EJP achieves higher
precision in bar, tube and profile
drawing, while improving ease
of operation and reducing
maintenance requirements.
Two years after EJP introduced
drawing machines with
servoelectrically actuated drawing
jaws as an alternative to hydraulic actuation, the
company has now taken their systems to the next
level. With linear motors it is no longer necessary to
convert the rotating movement of the actuation into
a linear movement. The advantages of this solution:
no indirect transmission of forces, fewer movable
parts and higher-precision drawing of bars, tubes
and profiles.
The linear motor design is a further development
of the servoelectric actuation of the drawing jaws,
a design that has proved highly successful in more
than ten machines built. In the combined drawing
machines featuring the new – patent-pending –
system, the motors control the actuation of the jaws
in real time based on the contour of the drawing cam,
closing and releasing the jaws as required.
Jacques Paraskevas, Managing Director of EJP, is
committed to offering his customers the best
solution for their specific requirements: “All three
drive solutions – hydraulic, servoelectric and linear
motor based – have their advantages depending on
the application. Therefore we will present all three
of them at WIRE 2018: one drawing unit equipped
with the new linear motors and one fitted with two
drawing carriages, of which one is equipped with a
servomotor and one with hydraulic cylinder. This
hands-on display will allow us to discuss with the
trade fair visitors in a best possible way what would
be the optimal solution for their specific application.“
The linear motors can be used in the complete
portfolio of combined EJP drawing machines
operating with drawing forces ranging between 2 and
46 tons and producing finished bars with diameters
from 2 to 60 mm.
