Technical Summary: Dual-Column Structure & Digital Angle Control
The CF-650DMS is an industrial-grade machine designed for dual-angle cutting of H‑beams. Its dual-column linear guide system eliminates vibration, while the 0.1° digital display enables quick setup of any angle from left 90°‑30° to right 90°‑45°. Combined with variable frequency speed control and a semi-automatic cycle, it offers a stable, high-efficiency cutting solution for metal fabrication shops.
How to Quickly Set Up a Dual‑Angle Cut on the CF-650DMS
Step 1 – Set the Angle: Use the digital panel to input the target angle (left 90°‑30° or right 90°‑45°); the system displays 0.1° precision in real time.
Step 2 – Clamp the Workpiece: Place the H‑beam or pipe on the table, adjust the vise width, and align the rotation center with the blade.
Step 3 – Start the Semi‑Automatic Cycle: Press the start button — the saw frame descends, completes the cut, and automatically returns to the preset height.

Features
What Core Design Features Make the CF-650DMS the Top Choice for Precision H‑Beam Cutting?
From dual-column linear guides and 0.1° digital angle control to variable frequency drive and semi‑automatic cycle, the CF-650DMS provides unmatched stability and efficiency for structural steel fabrication.
Dual‑Column Linear Guide System: The First Choice for Precision H‑Beam Processing
In the field of precision metal processing, the CF-650DMS Semi‑Automatic Miter Cutting Band Saw stands out for its outstanding stability. Developed for factories handling H‑beams, channels, and large pipes, the machine features a reinforced dual-column structure with linear guide rails on the saw frame path. This design completely eliminates the vibration and deflection common in single‑arm saws, dramatically improving cut surface precision.
0.1° Digital Precision & Intelligent Angle Adjustment
Equipped with a high‑precision digital display, operators get instant 0.1° feedback when adjusting dual‑angle cuts between left 90°‑30° or right 90°‑45°. This reduces manual measurement errors and greatly simplifies structural steel fabrication. The rotation center is located at the intersection of the fixed vise and the blade, ensuring accurate cutting lines at any angle.
Automation Features for Efficient Production
The machine is built with a variable frequency drive, allowing operators to fine‑tune blade speed (20‑90 m/min) for different metals such as carbon steel or alloy steel. After the cut, the saw blade automatically rises to a preset height, minimizing idle time. The 5° blade tilt design reduces contact area for higher cutting efficiency.
