16.5" rounds: 2012 Cosen Model: C-420NC NC Programmable Automatic Twin Column Horizontal Bandsaw 230v/60HZ/ 3-Phase With Chip Conveyor and Roller Table Note: std mfg specs below-please verify actual machine.. Cosen's C-420NC, incorporates a 7.5hp (10 hp optional) powerful blade motor, 1 ½” 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. As with all Cosen column type machines, this saw has a .50 kant. Cosen now offers the latest in Touch Screen Control Technology, SNC-100. Coupled with a Mitsubishi PLC controller the 5.7” Color Touch Screen allows for fast easy programming of any job. Utilizing the SNC-100 System the operator easily programs the cut length and quantity desired. The SNC-100 System stores up to 100 cutting jobs and features Automatic Kerf Compensation for parts longer than a single index. The SNC-100 System also utilizes “Save-A-Blade” which retracts the material 1/8” from the blade at the end of each cut so the blade will not rub the material while the saw head moves up to allow the next index. All machine functions are controlled from the operator’s station. The control panel is ergonomically designed and located for convenient use by the operator. Any length of cut desired up to 999”can be selected. MACHINE SPECIFICATIONS Maximum Cutting Capacity: Round:16.5" Square:16.5” x 16.5" Rectangle (w x h)16.5" x 16.5" Bundle (w/ opt. Top clamp)  7.5” x 4” min. 14” x 7” max. Blade: Speed Variable: 49 – 328 fpm blade sise:1 ½ ” x 15’8” x .050” 4770mm x 41mm x 1.3mm Carbide guides Motor: Hydraulic 10 hp Automatic Material Feed System: Job Storage Single Index Stroke Multiple Stroke Indexing Up to 100 jobs 0" to 19.750 " 0" to 999" (featuring automatic kerf compensation) Weight 7,260 lbs. Power 230V, 3 ph, 60 Hz Shipping Dimensions 107” x 90” x 80” Floor Space (L x W x H) 93" x 98" x 68" Bed Height 27.5” (700mm) 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: ► Cam lock carbide blade guides enable unsurpassed blade support and ease of blade changes. Carbide guides securely guide the blade during the cutting cycle. Also, 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. ► 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, and blade cleaning brush. Synchronized power driven blade brush effectively cleans chips from blade to extend blade life. Control & Automation: ► 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” 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  Motor amp draw (optional)  Optional Blade Deviation Detection monitor can be controlled directly from Touch Screen  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 3.5". ► Double retracting vise jaws. Both jaws of the index vise open (retract) and close assuring smooth material feeding, especially helpful for misaligned or cambered material. ► 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. ► 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 strategically located throughout 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 Note: currently sells new for $39,895.00
