COSEN C-320NC Automatic Duel Colum Horizontal Band Saw

Cosen’s C-320NC, incorporates a 5 hp powerful blade motor, 1 1/4” wide blade, independent control panel, and heavy-duty dual column design. These features create a very rigid, dynamically stable and productive machine. The oversized precision ground columns ensure smooth saw frame movement and the consistently stable cutting force required throughout the cutting cycle, thereby increasing the cutting efficiency and extending blade life.

MACHINE FEATURES
Machine Structure:
► Oversized Precision ground, large Dual Columns support and guide the rugged saw head
through the entire cutting cycle. The saw head adopts a back tilt design which allows the
blade to twist less than traditional bandsaws between the wheel and blade guide; thereby
putting less stress on the blade, insuring longer life.
► The oversized round columns provide hundreds of square inches of continuous surface
contact with the sawhead throughout the entire cutting process.
► Cross Link is located on the top of the columns, connecting the two columns to form an
archway design that gives it sound structural strength.
► Hydraulic shuttle vise assembly, made of heavy-duty cast iron with replaceable hardened
wear plates, rides on two large guide shafts that are capable of handling extreme loads.
Both shafts are ground and chrome plated for durability and smooth material feeding.
Blade Drive:
► The gearbox is specially designed to accept high lateral pressure. Unlike conventional
gearboxes, the Cosen design accepts more pressure during operation and will not create
thermal distortion, providing long gearbox life under production conditions.
► Inverter blade drive system allows infinitely variable blade speeds to be controlled by the
operator from the control panel with turn of a knob. The system comes standard with
LED readout for convenient and accurate setting of blade speed.
Blade Guidance & Lubrication System:
► Carbide guides securely guide the blade during the cutting cycle. The carbide is relieved
so that coolant can both cool and lubricate the blade during the cut.
► The bearing guides eliminate blade stress by pre-aligning the blade before it enters the
carbide guides. Two additional guides located on a central axis support the blade from the
top, giving it extra penetrating force for faster cuts.

►
Vibration damper can effectively reduce blade vibration produced under high-speed
cutting. Especially for cutting small materials on bandsaws of large width capacity, the
vibration damper can reduce blade vibration, increase cutting rate, and enable smooth
cut-off surfaces.
Automatic hydraulic blade tensioning device provides correct blade tensioning when the
machine is turned on and will slightly release the tension when the machine is not
running. This extends blade life. The on-off hydraulic valve switch is an added feature
making blade change quicker and easier
► Integral coolant system. Coolant is supplied at four critical points: exit & entry of blade
through blade guides, middle of cut via adjustable flex hose, and blade cleaning brush.
Synchronized power driven blade brush effectively cleans chips from blade to extend
blade life.
Control & Automation:
► The operator’s control station ergonomically located on the front side of the saw is
convenient and user friendly. All operator controls are positioned on the top of the control
box and clearly labeled for ease of operation. The electrical components are located inside
the control box with the main lockout disconnect on the front of the control box for safety
and easy maintenance.
► Smart NC-100 (SNC100) technology provides most of the benefits of NC controlled
saws at a mere fraction of the cost. SNC100 controls are programmable up to 100
different jobs including quantity and length of cut. The control automatically compensates
for Kerf loss after data input and requires no manual calculation of number of times to
index. The control also automatically shutdowns the machine, blade motor, and
hydraulics, once the programmed number of cuts or out of stock situation has been
achieved. The system includes an error feedback function enabling rapid troubleshooting
through an error code to be displayed in the event of a malfunction.

► SNC-100 Features include:
 5.7” HMI Touch screen
 Mitsubishi PLC controller
 100 individual jobs can be programmed and stored
 Stored program(s) may be easily recalled and executed at Will.
 Blade Speed Display
 Blade motor amp draw display (optional)
 Automatic Kerf Loss Compensation & Automatic Multiple Indexing up to 999”
 Save-a-Blade Feature – The shuttle vise will automatically retract the material
slightly after cut-off, so a blade can avoid the undesirable abrasion with material,
improving cutting tool life.
 Error Code Display Provides simplified self-diagnostics.
 Blade life timer.
► Precision feed pressure & feed rate dual valve system for optimal cutting performance in
any material.
Selector Switch for bundle or single cutting modes
► Automatic work height sensor and air gap eliminator positions the saw frame to a safe
clearance above the work piece, so that the next piece can be positioned without
damaging the blade. After feeding, the saw head will descend quickly to within
approximately 1/8″ of work piece, where it proceeds at the predetermined cutting rates.

Material Clamping & Feeding:
► Split vise jaws on the front machine vise are standard. The split front vise will hold the
work piece on both sides of the blade for a burr-free cut. This system also features
automatic feeding of material down to a remnant length of 2″.
► Hydraulic front and rear vises enable clamping and unclamping of any material from the
operator’s control station.
► Ductile cast iron vise with replaceable hardened wear plates.
► Smart NC Controlled Multiple indexing for long cutting lengths of up to 999” maximum
length, utilizing full shuttle length every index until desired length is reached.
One set of vertical alignment rollers, which is convenient for bundle cutting and
positioning bar stock, is standard and is located on the machine base.
Multiple horizontal rollers located on the entry side of the saw to facilitate smooth material
feeding.
Discharge Table with built–in coolant return adequately supports cut-off stock and
provides coolant savings in the long run.
Safety:
► Proximity switches sense both blade slippage and blade breakage and will automatically
shut off the machine if either of these conditions should occur.
► All blade covers, and guarding on the saw are painted Alert Orange to increase safety
alertness.
All exposed electric wiring and hydraulic circuit are protected by conduits.
Electrical and hydraulic safety interlock prevents saw blade to start without vises securely
clamped.

Accessories:
► Blade “clip” device eases blade changing when necessary by holding the blade on the
band wheel during installation, making it very easy for one person to change the blade.
► Adjustable fence to support bundled cut-off stock
Additional flushing hose for cleaning
Built in work light
Bi-metal saw blade
Tool Box with tools, leveling pads, and an additional wire brush

OPTIONAL ACCESSORIES
Applications involving threaded rod, polished/finished, rough, cambered, bent, forged,
extruded, or other non-standard/shaped material might need special options. Please
consult Cosen for quoting on special materials handling options.
Hydraulic chip conveyor – Hydraulic driven shaftless design allows maximum chip removal
rate without worrying about burnt up motor when material falls and binds in the chip
conveyor.
Vise pressure regulator – Infinitely variable clamping pressure between 0 and full system
pressure is easily adjusted and monitored by this device.
Double retracting vise – Both jaws of the index vise open (retract) and close assuring
smooth material feeding, especially helpful for misaligned or cambered material.
Hydraulic full stroke vises – allow full capacity movement for both machine and index vises
with just touch of a button. This option also comes with LED indicator lights to confirm
secure clamping.
Hydraulic top clamps – Hydraulically powered to provide secure clamping for bundle cut
applications.
Buck Boost Transformer – For incoming power of 208V 3PH or below, we recommend
adding a buck boost transformer for performance and stability of electrical components.
Micro Droplet Applicator – Adds an option for clean & mess-free cutting to the traditional
flood coolant system. Tiny drops of lubricant are applied via forced air to the cutting
points of the blade to lubricate the cuts and transfer the heat to the chips generated.
Permanent mount and magnetic mount options are available.
