Description

SHARP Model SW-240 NCD Dual Column Fully Programmable Auto. Horiz. Bandsaw, 24.4" Round
Sharp's SW-240 NCD incorporates a 10hp powerful blade motor, 54mm 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.
This NC operated hydraulic heavy duty double column automatic band saw that utilize the Smart NC-100 system to store most parameters and functions and programmed to perform most cutting jobs. The double column design ensure smooth saw frame movement and consistent stable cutting force to achieve high cutting efficiency and extended blade life.

Machine Structure:
1. 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.
2. The oversized round columns provide hundreds of square inches of continuous surface
contact with the sawhead throughout the entire cutting process.
3. 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.
4. 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:
1. The gearbox is specially designed to accept high lateral pressure. Unlike conventional
gearboxes, the Sharp design accepts more pressure during operation and will not create
thermal distortion, providing long gearbox life under production conditions.
2. 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 and Lubrication System:
1. Carbide blade guides are activated hydraulically for consistent and correct carbide guide
clamping to insure straight cuts. The guides are relieved to provide unsurpassed lubricating
and cooling of the blade and blade guides.
2. 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.
3. Heavy-duty cast guide arms effectively absorb vibration and enhance cutting result. The
movable guide arm is hydraulically actuated ensuring rapid and accurate movement.
4. 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
5. Integral coolant system. Coolant is supplied at three critical points: exit entry of blade through blade guides, and middle of cut via adjustable flex hose.
6. Synchronized power driven blade brush effectively cleans chips from blade to extend blade
life.

Control and Automation:
1. 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.
2. Smart NC Automatic Mass Production Band Saws 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 for 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 the number of times to index. The control also automatically shut down the
machine, blade motor and hydraulics, once the programmed number of cuts or out of stock
situation has been achieved.

3. SNC-100 Features include:
a. 5.7” HMI touch screen & Mitsubishi PLC controller.
b. 100 individual jobs can be programmed and stored.
c. Easily recalling and executing stored programs at will.
d. Automatic kerf loss compensation & automatic multiple indexing up to 99MM.
e. Convenient access to blade sped and blade life.
f. Save-a Blade – Automatic vise retracting after material cut-off, reducing abrasion
and improving blade life.
g. Rapid troubleshooting through error feedback system.
h. Friendly maintenance reminder signals.

4. Precision feed pressure & feed rate dual valve system for optimal cutting performance in
any material.
5. Selector Switch for bundle or single cutting modes
6. 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 and Feeding:
1. 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 7.87";.
2. Double Retracting Index Vice Jaw- Both jaws on the vise open (retract)  to reduce rubbing
especially on misaligned or crooked stock increasing index length accuracy and repeatability.
3. Full stroke hydraulic front and rear vises enable clamping and unclamping of any material
from the operator’s control station with touch of a button.
4. Ductile cast iron vise with replaceable hardened wear plates.
5. Smart NC Controlled Multiple indexing for long cutting lengths of up to 650” maximum
length, utilizing full shuttle length every index until desired length is reached.
6. 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.
7. Multiple horizontal rollers strategically located throughout the saw to facilitate smooth
material feeding.
8. Discharge Table with built–in coolant return adequately supports cut-off stock and provides
coolant savings in the long run.

Safety:
1. Proximity switches sense both blade slippage and blade breakage and will automatically
shut off the machine if either of these conditions should occur.
2. All blade covers, and guarding on the saw are painted Alert Orange to increase safety
alertness.
3. All exposed electric wiring and hydraulic circuit are protected by conduits.
4. Electrical and hydraulic safety interlock prevents saw blade to start without vises securely
clamped.
