CF-460AW
Store Manager's Choice
Automatic Column Type Metal Band Saw
The CF-460AW Automatic Dual Column Metal Bandsaw is engineered and manufactured by Big Stone Machinery at its Hsinchu headquarters in Taiwan, specifically developed for heavy-duty, high-volume 90-degree straight cutoff operations across large forged steel rounds, mold steels, and structural sections. The machine delivers 90° straight cutting capacity of Ø460 mm (Ø18.1") solid rounds and 460 × 460 mm (18.1" × 18.1") square cross-sections. Built upon a rigid dual-column gantry frame and 41 mm (1.61") wide blade assembly to eliminate cutting chatter, it features an exclusive Split Front Vise Clamping Mechanism on both sides of the blade channel to prevent material drop, blade pinching, and burr formation. Integrated with a 500 mm (19.7") hydraulic shuttle hitch-feed system, a 5.5 kW (7.5 HP) inverter variable-speed drive (20–90 m/min / 66–295 FPM), industrial PLC touchscreen automation, and a motorized chain-plate chip conveyor, the CF-460AW ensures vibration-free, highly planar unattended batch production.
Why is the CF-460AW the Premier Dual-Column Bandsaw for Heavy Forged Billets and Industrial Mass Production?
Dual Column Rigidity & 41 mm (1.61") Heavy Blade Vibration Damping: The symmetric twin-column gantry structure combined with a 41 mm wide blade provides outstanding machine stiffness, neutralizing high-frequency micro-chatter when slicing Ø460 mm (Ø18.1") solid alloy steel rounds. Rigid clamping on both entry and cutoff sides eliminates blade pinch and rough tear-off burrs upon cut completion.
500 mm (19.7") Hydraulic Shuttle Infeed & Continuous Chip Evacuation: A heavy-duty roller bed working in tandem with full-stroke alternating hydraulic hitch-feed vises ensures high repeat indexing accuracy. Combined with an automated chain chip conveyor, it fulfills 24-hour lights-out batch processing demands for steel service centers and heavy forging facilities.

What Key Engineering Technologies Make CF-460AW the Top Choice for Heavy-Duty Automatic Dual-Column Bandsaws?
Engineered for steel distribution centers, mold steel processing plants, and heavy forging operations, the CF-460AW combines gantry- grade structural rigidity with automated split-vise material handling:
Heavy-Duty Twin Column Gantry Architecture
Symmetrical dual cylindrical columns provide exceptional torsional rigidity, suppressing cutting harmonics to maintain mirror- smooth cut surfaces across 460 mm (18.1") alloy steel blocks.
Split Front Vise Dual Clamping System
Hydraulic vises grip the workpiece firmly on both the front and rear sides of the cutting channel, completely preventing billet drop, blade pinching, and end-face burr tearing.
500 mm (19.7") High-Precision Shuttle Infeed
A heavy roller bed paired with dual full-stroke hydraulic vises delivers 500 mm per stroke, supporting multi-index auto-cycling for continuous automatic billet advancement.
5.5 kW (7.5 HP) Inverter Stepless Speed Control
A broad variable blade speed window (20–90 m/min / 66–295 FPM) allows operators to fine-tune linear blade speeds directly from the PLC for carbon steels, tool steels, and superalloys.
Industrial PLC Touchscreen Automation Cycle
The intuitive touch interface supports multi-group length and piece-count programming, automating hydraulic clamping, feeding, sawing, and rapid head retract.
Motorized Chain Chip Conveyor & Safety Interlocks
A continuous chain-plate conveyor removes heavy chip loads in real time; built-in blade slippage and breakage sensors immediately halt operation to safeguard unattended shifts.

How to Set Up Automatic High-Volume Batch Slicing on CF-460AW: 3-Step Field Guide
Utilizing the PLC touchscreen panel and 500 mm (19.7") shuttle hitch-feed mechanism, operators can initiate automated production in 3 standardized steps:
-
1
Step 1: Program Cutting Parameters via the PLC Touch Interface
Input target cut length, batch piece count, and linear blade speed (20–90 m/min / 66–295 FPM) on the touchscreen; the controller automatically computes optimal 500 mm shuttle index strokes.
-
2
Step 2: Load Stock and Engage Split Hydraulic Vises
Position the heavy steel billet onto the roller bed; activate full-stroke hydraulic split vises to lock the stock securely across both sides of the blade channel.
-
3
Step 3: Execute Automatic Cycling and Chip Evacuation
Press cycle start; the machine executes dual-vise hitch feeding, rigid vertical downfeed along twin columns, and real-time chip disposal until the full batch is completed.
