Cutting torque upgrades
Several options can be used to increase the cutting torque:
● CSC-2 and 3 cutters can be upgraded from a 2.7 HP
(MGE-455) to a 3.8 HP (MGE-490) servo motor. (The
larger servo motor is standard on CSC-4 and 5 cutters.)
● The standard aluminum cutter-head can be replaced with a
heavier stainless steel one. When this option is picked, the
maximum number of cuts per minute decreases from 400
to 200. Inertia, and thus cutting torque, is increased sig-
nificantly.
Follower Cutting Mode
Follower mode allows the operator to program the desired cut
length and the number of blades. The controller then automati-
cally follows the encoder and adjusts the speed of the cutter
head to maintain cut length. This is known as an electronic
gearlock system. The cut length accuracy is maintained even if
the puller changes speed. A 3,000 pulse per revolution encoder
is used for this option using the Quadrature (x-4) mode, giving
12,000 pulses per foot for extreme accuracy and repeatability.
Slide Base
This option is highly recommended for cutting flexible extru-
dates. While the cutter base is fixed and aligned with the
puller, the cutter itself is mounted on a set of linear slides that
allow as much as 6 inches of movement. The cutter can be
moved away from the puller for startup, then moved close to
the puller to enhance delivery to the cutter bushings.
Bushing Lubrication
This is a self-contained spray system, which includes a reser-
voir and air inlet for operation at 20-30 psig (air source not
included). A flexible nozzle directs lubricant onto the extru-
date as it enters the cutter bushings. This decreases bushing
drag and helps lubricate the blade. This option is particularly
recommended for processing sticky/soft (low durometer)
materials.
Auto Cutting Mode
Auto Cutting mode allows the operator to program the desired
cut length and the number of blades and desired blade speed.
The controller then automatically follows the encoder and
adjusts the speed of the cutter head to maintain cut length at
desired blade speed. This is known as an electronic gearlock
system. The cut length accuracy is maintained even if the
puller changes speed. A 3,000 pulse per revolution encoder is
used for this option using the Quadrature (x-4) mode, giving
12,000 pulses per foot for extreme accuracy and repeatability.
