Automatic Column Type Metal Band Saw

The Big Stone CF-360AW is an industrial heavy-duty automatic double-column horizontal metal band saw engineered for high-precision, burr-free mass production slicing of solid alloy steel bars, heavy tool steel billets, and thick-walled structural profiles up to Ø360 mm (Ø14.2 in.) and 360 × 360 mm (14.2 × 14.2 in.). Featuring a rigid dual-column gantry saw frame, a patented split vise clamping system on both sides of the cutting plane, a 500 mm (19.7 in.) single-stroke hydraulic shuttle indexing table, and an inverter variable speed drive, the CF-360AW delivers repeatable cutting accuracy of ±0.1 mm (±0.004 in.) for continuous heavy manufacturing operations.

Specification

Why Choose the Big Stone CF-360AW Double Column Band Saw for Slicing Heavy Tool Steels & Solid Alloy Bars?

Conventional scissor-type (pivot) band saws frequently encounter torsional blade deviation, high-frequency harmonic chatter, and severe exit- burr formation when slicing high-tensile solid rounds exceeding Ø300 mm. The Big Stone CF-360AW overcomes these industrial limitations through three purpose-engineered structural advancements:

1. Symmetrical Double-Column Gantry Framework: Dual hard-chromed guide columns paired with precision-honed guide bushings form a closed structural loop. Balanced downfeed cylinders eliminate cantilever frame twisting, keeping vertical kerf deviation strictly within 0.1 mm while extending band blade service life by over 30%.
2. Split Vise Clamping System Across Cutting Plane: Independent hydraulic vise jaws clamp the workpiece firmly on both the infeed and cut-off sides. As the blade exits the cut, the severed workpiece cannot drop or pinch the saw blade, ensuring completely flat, burr-free end faces that eliminate secondary facing passes.
3. Hydraulic Shuttle Table with Multi-Stroke Indexing: A 500 mm (19.7 in.) single-stroke hydraulic floating feed vise works in conjunction with magnetic/optical encoders, automatically executing repeated indexing cycles for long stock with ±0.1 mm repeatability.

90 deg. Round Capacity: Ø360 mm (Ø14.2 in.) 90 deg. Rectangular Capacity: 360 × 360 mm (14.2 × 14.2 in.) Frame Architecture: Dual-Column Gantry Type Material Infeed: 500 mm (19.7 in.) Hydraulic Indexing Main Motor: 3.75 kW (5.0 HP) Inverter VFD Cutting Accuracy: ±0.1 mm (±0.004 in.)

6 Core Industrial Engineering Advantages of the Big Stone CF-360AW

1. Rigid Dual-Column Gantry Structure

The saw head travels along dual precision-ground, hard-chromed vertical columns housed in heavy wear-resistant bushings. Unlike pivot-style saws, this balanced gantry design absorbs severe cutting forces symmetrically, eliminates vibration, and maintains squareness within 0.1 mm across heavy alloy cuts.

2. Full-Stroke Split Vise Clamping (Both Sides)

Hydraulic vise jaws clamp the workpiece simultaneously before and after the blade kerf line. As the cut finishes, the material remains rigidly supported, preventing kerf closure, blade jamming, and catastrophic teeth stripping while producing clean, burr-free cut surfaces.

3. 500 mm (19.7 in.) Hydraulic Shuttle Indexing

Equipped with a 500 mm single-stroke hydraulic indexing vise monitored by precision encoders. The controller seamlessly executes multi-cycle indexing (e.g. 1,500 mm requires only 3 automated strokes) with repeatable positioning accuracy of ±0.1 mm (±0.004 in.).

4. 3.75 kW (5.0 HP) Inverter & Carbide Guides

Powered by a 3.75 kW heavy-duty inverter drive offering stepless blade speed regulation from 20 to 120 m/min (66 to 394 FPM). Ultra-hard tungsten carbide guide blocks and ball bearing roller assemblies stabilize the blade under high tension for optimal heat dissipation.

5. Motorized Spiral Chip Conveyor & Flood Coolant

A heavy-duty spiral chip auger continuously extracts metal swarf from the cutting bed directly into an external collector, preventing chip build-up around guide columns. High-volume coolant nozzles wash the blade and kerf to maintain cutting efficiency.

6. Microcomputer Controls with Blade Breakage Protection

A centralized digital operator console allows presets for batch piece counts, target cut lengths, and downfeed rates. Automatic rapid approach sensors, out-of-stock shut-off, and an electro-hydraulic blade tension sensor stop the machine instantly if blade breakage occurs.

CF-360AW 3-Step Standard Operating Procedure for Mass Production

1

Program Cut Length & Load Material

Input target cut length (e.g. 150 mm) and batch quantity (e.g. 100 pcs) on the digital console. Advance bar stock into the shuttle vise and verify hydraulic pressure gauges reach 25–30 kg/cm² for positive clamping.

2

Calibrate Blade Speed & Downfeed Rate

Select optimal blade speed via the inverter potentiometer based on material metallurgy (e.g. 45–55 m/min for AISI 4140). Adjust the hydraulic feed valve to ensure uniform chip curl, then activate coolant and chip conveyor.

3

Initiate Fully Automated Production Cycle

Press "Auto Cycle Start". The CF-360AW automatically clamps the split vise → downfeeds smoothly through the cut → retracts the saw head → unclamps the split vise → indexes material forward 150 mm via the shuttle table → repeats continuously until the batch is finished.

Industrial Customer Field Verification & Performance Reviews

David K. - Plant Operations Manager, Heavy Forging & Tooling Facility ★★★★★ 5.0 / 5.0

"We slice large batches of SKD11 and AISI 4140 solid round billets between Ø250 mm and Ø320 mm daily. On our previous pivot band saws, the cut-off ends would sag and strip blade teeth right before completing the cut. The Big Stone CF-360AW's split vise clamps both sides firmly through the finish, resulting in dead-square, burr-free end faces. It completely eliminated our secondary face-milling bottleneck!"

Markus S. - Quality Control Director, Structural Precision Machining Works ★★★★★ 5.0 / 5.0

"The 3.75 kW inverter motor and rigid gantry frame show virtually zero resonance during heavy alloy cutting. The 500 mm shuttle table feeds reliably all night long with indexing accuracy under ±0.1 mm. Blade life has increased by over 30% compared to our legacy saws. Big Stone Machinery delivers outstanding Taiwanese manufacturing precision and technical reliability."

Big Stone CF-360AW Technical FAQ for Machine Tool Buyers & Importers

Q1: How does the split vise clamping system prevent blade binding on solid tool steels?
Traditional band saws only clamp on the infeed side. As the blade approaches the bottom of a heavy billet, the cut-off section sags under gravity, closing the kerf and pinching the band blade or creating severe ragged burrs. The CF-360AW features dual split vise jaws on both the infeed and cut-off sides of the blade path. The workpiece remains rigidly supported on both sides until separation is complete, guaranteeing clean, square cuts and dramatically extending blade life.
Q2: If my target cut length exceeds the 500 mm single-stroke limit, how does multi-indexing work?
The CF-360AW features automated multi-cycle shuttle indexing. For example, if you input a 1,200 mm cut length, the hydraulic feeder automatically advances three consecutive cycles (500 mm + 500 mm + 200 mm) before executing the cut. High-precision encoders and proximity sensors maintain cumulative positioning repeatability strictly within ±0.1 mm (±0.004 in.).
Q3: What makes a double-column gantry superior to a scissor-type saw for solid steel?
Scissor (pivot) band saws rotate around a single rear hinge pin, creating uneven downfeed force and torsional frame twisting across wide sections. The CF-360AW utilizes symmetrical dual hard-chromed guide columns with balanced hydraulic cylinders. The downfeed force is applied directly over the cut center, providing high rigidity and vibration dampening for continuous automated mass production.
Q4: What are the commercial payment terms, manufacturing lead time, and warranty policy?
The standard factory manufacturing lead time (handling time) for the CF-360AW is approximately 20 to 30 business days. Standard international commercial payment terms are Telegraphic Transfer (T/T): 30% advance deposit upon purchase order confirmation and 70% balance prior to factory dispatch. Big Stone provides a 1-year comprehensive machine parts warranty and long-term main structural support.
Q5: Can the CF-360AW be configured for nesting multiple bars in bundle cutting?
Yes. For high-volume production of small round or square bars (e.g. Ø50–100 mm), an optional hydraulic top clamping bundle vise is available. The top clamp exerts downward hydraulic force synchronized with the horizontal split vises, locking bundled bars into a compact matrix that prevents individual bar slippage during rapid indexing.
