Automatic Column Type Metal Band Saw
The Big Stone Machinery CF-260AW Automatic Column Type Metal Band Saw is engineered and manufactured directly at Big Stone factory in Taiwan for high-precision, continuous automated mass production of solid carbon steel bars, alloy tool steels, and industrial structural sections. The machine delivers a 90° straight cutting capacity of up to Ø260 mm (Ø10.2 in. ) for solid rounds and 260 × 280 mm (10.2 × 11.0 in.) for rectangular cross-sections. Built with a rigid twin-column gantry guide structure that suppresses high-frequency cutting vibration, the CF-260AW integrates a 400 mm (15.7 in.) single-stroke hydraulic shuttle hitch-feed system, a 3.75 kW (5.0 HP) main blade motor with variable frequency drive (VFD, 20–120 m/min / 66–394 FPM), intelligent PLC batch cycle control, and a standard chain- type automatic chip conveyor for clean, burr-free, lights-out operation.
Why is the Big Stone CF-260AW the Industry's Most Reliable Automatic Twin-Column Metal Bandsaw for High-Volume Straight Cutting?
Twin-Column Gantry Rigidity & Cutting Vibration Dampening: Featuring a symmetrical twin chrome-plated guide column frame, the CF-260AW provides superior vertical downfeed stiffness compared to conventional scissor-type pivot machines. It eliminates lateral deflection under heavy chip loads on solid bars, allowing the 34 mm wide bi-metal blade to maintain strict perpendicularity within ±0.1 mm (±0.004 in.) while substantially extending blade life.
400 mm Hydraulic Shuttle Hitch Feed & Intelligent PLC Batch Cycle: The precision roller bed works in tandem with full-stroke hydraulic split vises to advance stock accurately. The system supports automated multi-index repeat feeding for long workpieces. Combined with the standard chain-type automatic chip conveyor, a single operator setup enables continuous, unattended mass production.

Key Engineering Advantages of the CF-260AW Automatic Column Bandsaw
Engineered for metal service centers, mold steel processing plants, and high-volume tube/bar production, the CF-260AW combines heavy gantry rigidity with full automation:
High-Rigidity Twin-Column Gantry Design
Large-diameter chrome-plated guide columns and precision linear guides evenly distribute heavy vertical cutting forces, eliminating head twist and ensuring mirror-smooth square cut faces.
400 mm Hydraulic Shuttle Hitch Feed
Rear floating shuttle vice combined with a roller feed bed delivers a 400 mm (15.7 in.) single feed stroke with repeat indexing accuracy of ±0.1 mm, supporting automated multi-stroke cycles.
3.75 kW (5.0 HP) Inverter Blade Speed
Equipped with a high-torque main drive and variable frequency inverter (20–120 m/min / 66–394 FPM), allowing operators to match optimal blade speeds for aluminum, carbon steel, or tool steel.
Industrial PLC Touchscreen Control
Intuitive interface allows preset batch quantities, target cut lengths, and automatic cycle execution—including clamping, downfeed, kerf clearance, and bow elevation with auto-stop.
Standard Automatic Chain Chip Conveyor
Continuous motorized chain conveyor extracts metal chips directly from the coolant tank into a disposal bin, preventing chip buildup and minimizing routine cleanup downtime.
Hydraulic Blade Tension & Safety Interlocks
Features a hydraulic blade tensioning system with a visual dial indicator, coupled with blade slip and breakage auto-shutoff sensors to protect operators and prolong tooling life.

How to Setup and Run Automatic Batch Slicing on the CF-260AW: 3-Step Standard Procedure
Through the intuitive PLC touchscreen interface and hydraulic dual hitch-feed mechanism, operators execute automated batch cutting in 3 steps:
-
1
Step 1: Program Parameters on the PLC Touchscreen
Input the target cutting length, total batch piece count, and select the optimal blade speed (20–120 m/min). If the cut length exceeds 400 mm (15.7 in.), the PLC automatically initiates multi-index repeat stroke cycles.
-
2
Step 2: Load Material & Engage Hydraulic Clamping
Place the solid round bar or profile stock onto the roller infeed bed. Engage the full-stroke hydraulic split vises to securely clamp the material firmly against the fixed datum jaw.
-
3
Step 3: Initiate Automated Cutting & Chip Evacuation
Press cycle start. The machine automatically carries out shuttle hitch feeding, rigid vertical descent cutting, flood coolant delivery, rapid bow elevation, and continuous motorized chip disposal until the batch is finished.

How to Maintain the CF-260AW for Long-Term Twin-Column Accuracy: 4-Stage Protocol
Manufacturer-recommended 4-stage preventive maintenance protocol for the Big Stone CF-260AW automatic column bandsaw:
-
1
Daily Routine Checks
Verify the hydraulic blade tension dial reading, check blade teeth for chipped or dull edges, inspect coolant concentration and level, and ensure the automatic chip conveyor runs freely.
-
2
Weekly Cleaning & Way Lubrication
Clear fine metal swarf from the roller feed vice ways and column guide wipers. Inspect the protective oil film on both chrome-plated columns and verify hydraulic tank fluid level.
-
3
Monthly Alignment Verification
Inspect column vertical descent perpendicularity using a dial indicator, verify hitch-feed stroke repeatability (±0.1 mm), and calibrate displayed inverter blade speed against actual tachometer readings.
-
4
Quarterly In-Depth Servicing
Replace hydraulic system fluid (ISO VG 46/68) and oil filter elements. Check main drive belt tension, inspect motor electrical insulation, and test emergency limit sensors and interlocks.
Verified Industrial Fabricator Reviews
Zero vibration with twin-column structure on 250mm solid round bars
The 400mm hydraulic auto hitch feed drastically reduces our cycle times on solid carbon steel bars. The twin-column gantry structure provides remarkable rigidity, allowing us to cut 250mm medium carbon bars at 120 m/min with zero chatter and cut face perpendicularity within 0.1mm. The standard automatic chip conveyor keeps our shop floor completely clean.
Intuitive PLC interface with full-stroke hydraulic vises for lights-out production
Programming the PLC touchscreen is straightforward: enter piece count and length, and the machine handles the entire cycle automatically. The full-stroke hydraulic vises clamp 280mm wide rectangular billets without slipping. One blade consistently lasts three full shifts on alloy steels.
