CNC Double Miter Cutting Metal Band Saw

Why Are the 5030DMA & 5050DMA the Top Choice for Heavy Structural Steel Double Miter Cutting?
Answer: Both models feature CNC fully automatic bidirectional miter cutting (+60° to -45°), a servo feed system, and extended auto-feed strokes — 2500 mm on the 5030DMA and 4500 mm on the 5050DMA — designed for high-volume precision cutting of profiles, pipes, and solid metals.

The 5030DMA and 5050DMA are Big Stone Machinery's CNC double miter band saws for heavy-duty metal processing. They combine a high-rigidity frame, CNC digital control, and automated material feeding to effortlessly handle high-volume production of structural steel, pipes, and solid bars with complex angle requirements.

Technical Overview: High-Productivity Solution for Heavy Structural Cutting
The 5030DMA and 5050DMA series represent the pinnacle of digital precision cutting, engineered for a wide range of compound angle cutting requirements. Both models are equipped with advanced CNC automation and exceptional bidirectional angle flexibility (positive and negative miter cuts). Whether in a large manufacturing plant or a specialized fabrication shop, they deliver high-efficiency, low-error automated mass production when processing pipes, profiles, and solid metal stock.

How to Quickly Set Up a Double Miter Cut on the 5030DMA/5050DMA
Step 1 – Enter Parameters: On the CNC touchscreen, select dual miter mode and enter the angle (+60° to -45°), length, and number of pieces.
Step 2 – Automatic Positioning: The servo feed system advances the material to the start point; the saw head rotates to the target angle with 0.1° accuracy.
Step 3 – Start the Cycle: Press the start button — the machine sequentially feeds, clamps, cuts, and ejects the remnant, all fully automated.

5030DMA / 5050DMA Core FAQs
Q: What is the maximum cutting capacity of the 5030DMA and 5050DMA?
A: At 90°, Ø325 mm round and 320 × 500 mm rectangular.
Q: How long is the automatic feed stroke?
A: The 5030DMA offers 2500 mm per stroke; the 5050DMA extends to 4500 mm.
Q: Do these machines rely on hydraulic systems?
A: The saw head rotation and blade feed are servo‑motor controlled, dramatically reducing hydraulic maintenance.
