650DMA~1300DMA
CNC Double Miter Cutting Metal Band Saw
How Does the Big Stone 650DMA–1300DMA Dual-Column Gantry Series Achieve Vibration-Free Precision Mitering for Heavy Structural Steel?
The Big Stone Dual-Column Gantry CNC Double Miter Band Saw Series (650DMA, 705DMA, 800DMA, 1000DMA, and 1300DMA) is engineered and manufactured at Big Stone's main manufacturing plant in Hsinchu, Taiwan (plant area: 4,650 m² / ~50,052 sq ft). Engineered for heavy structural cutting capacities from 440 × 650 mm (17.3 × 25.6 in.) up to 700 × 1300 mm (27.6 × 51.2 in.) [Round Ø450 mm (Ø17.7 in.) to Ø760 mm (Ø29.9 in. )], the symmetrical twin-column linear guideway frame eliminates cutting resonance and blade twisting. Standard equipment includes a 2300 mm (90.6 in. / 2.3m) servo long-stroke auto infeed carriage (±0.15 mm / ±0.006 in. repeatability) and 90°, Left 45°/30°, and Right 45°/30° CNC auto-swivel miter positioning (0.1° accuracy). The outfeed end can be paired with optional modular passive auxiliary roller tables (1m, 2m, 3m, 5m), executing opposite-angle cuts on 6m to 12m (20–40 ft) structural beams with no workpiece flipping required. Featuring a 250+ digital cutting recipe library, 20–90 m/min (65–295 FPM) inverter variable blade speed, and hydraulic spray mist cooling (MQL), the series is CE Certified and ISO 14064-1:2018 verified, designed specifically for heavy H-beam fabrication, shipbuilding, bridge construction, and offshore wind tower structures.

How to Operate the 650DMA–1300DMA for Automated Structural Steel Double-Miter Sawing: 3-Step Guide
Standard Operating Workflow: Plant operators recall stored cutting parameters from the 250+ recipe library on the 10-inch CNC touchscreen, activate the 2300 mm servo infeed, and initiate continuous twin-column automatic cutting cycles:
-
Step 1 – Recall Stored Cutting Recipe or Input Dimensions, Angles, and Quantities
Directly recall pre-saved structural steel parameters from the 250+ recipe database via the 10-inch color CNC touchscreen, or input beam cross-section dimensions, target cut length, miter angle (90°, Left 45°/30°, Right 45°/30°), and batch quantity.
-
Step 2 – Load Raw Material, Execute 2300mm Servo Infeed, and Engage Hydraulic Clamping
Position the heavy structural beam on the powered infeed table. The 2300 mm servo carriage advances the material to the target coordinate (±0.15 mm repeatability), the saw bow auto-pivots to the programmed angle, and heavy-duty hydraulic vices clamp firmly.
-
Step 3 – Initiate CNC Full-Automatic Dual-Column Continuous Cutting Cycle
Press cycle start. The variable inverter blade drive and hydraulic spray mist lubrication activate for steady downfeed cutting; upon cut completion, the bow lifts automatically, the material indexes forward, and the cycle repeats automatically until the batch is finished.
Three High ROI Strategic Advantages of 650DMA–1300DMA for Heavy Metal Fabrication Centers
🏛️ Twin-Column Anti-Vibration Rigidity
Symmetrical dual linear guideways eliminate heavy cutting chatter, extending band saw blade operational lifespan by over 30% on 650–1300 mm wide structural beams.
⚡ 2300 mm Servo Long-Stroke Feeder
Reduces material regripping time by over 65% when indexing 6m to 12m commercial beams, maintaining rigorous repeatability within ±0.15 mm (±0.006 in.).
📊 250+ Digital Recipe Database
Stores complete angle, length, and batch parameters for instant changeover, preventing manual operator programming errors on busy production floors.
