MFG HX-33/42S Semi-Automatic Rotary Cutting Metal Band Saw

0-45° Hydraulic Miter Cutting, PLC Auto-Feeding & 330x420mm Profile Capacity

Product Overview
The MFG HX-33/42S is an advanced semi-automatic horizontal metal band saw specifically engineered for the high-precision processing of small to medium-sized round pipes, square steel tubes, and complex structural profiles.

Beyond standard 0° straight cuts, the HX-33/42S features a highly accurate 0-45° rotary sawing capability driven by an independent hydraulic system and a precise rotary encoder.

Equipped with an intelligent PLC touch screen, hydraulic automatic feeding with linear scale feedback, and a stepless Variable Frequency Drive (VFD), this machine delivers exceptionally narrow kerfs, substantial material savings, and superior production efficiency for modern steel fabrication facilities.

Key Features & Engineering Details

• 0-45° Precision Rotary Cutting System: The machine's angle rotation is driven by a dedicated hydraulic cylinder, with exact angles continuously calculated by a high-precision rotary encoder and displayed directly on the touch screen. Once the target angle is reached, a hydraulic T-slot cylinder firmly locks the rotary seat to the heavy-duty welded base, completely preventing displacement and angular deviation during heavy cuts.
• Intelligent Auto-Feeding & PLC Control: Moving beyond traditional button panels, all machine actions are controlled via a centralized PLC touch screen. The automatic hydraulic feeding vise moves along a circular guide rail with a maximum single stroke of 400 mm. The feeding length is detected by a precise linear scale (grating ruler), guaranteeing an exceptional feeding tolerance within ±0.2 mm. Operators can pre-program up to 5 distinct groups of feeding lengths and quantities simultaneously.
• Stable Double-Column Architecture: The saw frame's vertical lifting is powered directly by a heavy-duty cylinder piston rod acting as the main column. To maximize cutting stability and eliminate vibration across the cutting span, a secondary auxiliary small-cylinder column is integrated at the left end of the bow-shaped saw frame.
• Stepless VFD & Bevel Helical Drive: The main transmission features a premium bevel helical gear reducer that delivers smooth, impact-free torque. Coupled with a Variable Frequency Drive (VFD), the speed of the driving wheel is steplessly adjustable, allowing operators to perfectly match the blade speed to different metal hardness levels.
• Automatic Feed Overload Protection: An intelligent throttle valve mechanism is installed above the fixed guide head. If the downward feed rate causes excessive blade thrust against the material, a mandrel pushes the guide head upward, automatically reducing the throttle valve opening. This instantly slows the descending speed, preventing tooth stripping and dramatically extending blade life.
• Precision Guiding & Clamping: The blade is secured by fixed and movable guide arms mounted on a dovetail crossbeam, complete with a pre-guide system. Workpieces are clamped via a highly efficient dual-action hydraulic vise (a lead screw handles rapid coarse positioning to within 20mm, followed by a 50mm hydraulic cylinder stroke for ultimate clamping pressure).
• Independent Hydraulics & Chip Management: An independent hydraulic station (with fan-cooled return oil) isolates heat from the main machine bed. Additionally, a built-in helical (spiral) chip conveyor automatically extracts metal shavings, significantly reducing operator labor and maintaining a clean work environment.
