CNC Band Sawing Machine for H-Beams

Product Overview

The CNC Band Sawing Machine (Model FHS-600) is a dedicated solution for high-precision cutting of H-beams, designed to meet the demands of steel structure fabrication, heavy machinery, and infrastructure projects. It combines automatic feeding, variable-speed sawing, and robust construction to deliver clean, consistent cuts on H-beams of various sizes, reducing material waste and manual labor.

• High cutting efficiency: 30% faster than manual band saws via servo-driven feeding.

• ±0.1mm cutting accuracy ensures H-beam dimensional consistency for structural assembly.

• Handles H-beams with heights up to 600mm and widths up to 400mm.

• Automatic material clamping and chip removal minimize operator intervention.

Product Features

High-Capacity Cutting Performance

The machine’s primary advantage lies in its ability to cut H-beams up to 1200×500mm in cross-section, making it suitable for even the largest structural members used in commercial construction and industrial facilities. The band saw blade operates at variable speeds from 20 to 120 m/min, with automatic speed adjustment based on material thickness and hardness—optimizing cutting efficiency while extending blade life. A powerful 15 kW drive motor ensures consistent cutting force even through high-tensile strength steels up to 690 MPa.

Precision Positioning System

Accurate length control is critical in H-beam fabrication, and this machine delivers with ±1mm length tolerance across its entire working range. The CNC system controls a servo-driven material feeding table that positions workpieces with exceptional accuracy, even for lengths up to 12 meters. A laser positioning guide provides visual confirmation of the cut line, while a digital length readout on the HMI allows operators to monitor and adjust positions in real-time.

Automated Material Handling

To maximize productivity, the machine incorporates several automated material handling features, including a powered roller conveyor system that transports H-beams into the cutting zone without manual lifting. An automatic clamping system secures workpieces during cutting, with adjustable pressure settings to prevent distortion of thin-walled sections while ensuring stability for thick flanges. After cutting, a discharge conveyor moves finished pieces to a collection area, enabling continuous operation for unattended production runs.

Intelligent Cutting Optimization

The machine’s CNC system includes proprietary cutting optimization software that analyzes H-beam dimensions and material properties to recommend optimal cutting parameters. This software can nest multiple cut lengths from a single beam, minimizing material waste by up to 15% compared to manual planning. Operators can store up to 500 cutting programs, each containing specific parameters for different H-beam sizes and material types, allowing for quick changeovers between production jobs.

Applications

Structural Steel Fabrication

The primary application of this machine is in steel structure manufacturing facilities, where it cuts H-beams for use in commercial buildings, industrial plants, and infrastructure projects. Its ability to produce precise, square cuts ensures proper fit-up during beam assembly and welding, reducing the need for secondary grinding or machining operations.

Bridge Construction

In bridge building, where H-beams form critical load-bearing components, the machine’s precision cutting ensures proper alignment of girders and supports. Its capacity to handle large H-beam sizes makes it ideal for processing the heavy structural members used in highway overpasses and railway bridges.

Industrial Equipment Manufacturing

The machine also serves manufacturers of heavy industrial equipment, cutting H-beams for use in crane structures, conveyor systems, and machinery frames. Its consistent cut quality ensures interchangeability of components, a key requirement for equipment assembly and maintenance.

Renewable Energy Structures

In wind energy and solar power projects, the machine processes H-beams used in turbine support structures and solar panel mounting systems. The precision cutting ensures the structural integrity required to withstand environmental loads in these outdoor applications.

FAQ

What type of band saw blade is recommended for H-beam cutting?

We recommend bi-metal band saw blades with 10–14 teeth per inch (TPI) for most H-beam applications. For high-tensile steel beams, carbide-tipped blades are available as an option, extending blade life by approximately 300% compared to standard bi-metal blades.

How long does a typical blade last under normal operating conditions?

Under standard conditions cutting mild steel H-beams, a bi-metal blade typically achieves 80–120 hours of cutting time before requiring replacement. This can vary based on material hardness, cutting speed, and maintenance practices—proper blade tension and coolant flow significantly impact blade life.

Can the machine cut other structural shapes besides H-beams?

Yes, with appropriate fixturing, the machine can cut I-beams, channels, and square tubing up to 500mm in maximum dimension. The CNC system includes pre-programmed cutting parameters for common structural steel shapes.

What is the machine’s production capacity per shift?

In a typical 8-hour shift with standard 6-meter H-beams, the machine can produce approximately 150–200 cut pieces depending on cut length and material thickness. This represents a 30–50% increase in productivity compared to manual band saws.

Does the machine require a dedicated operator?

While an operator is required for material loading and system monitoring, the machine’s automation features allow one operator to manage multiple machines simultaneously. The CNC system includes automatic error detection and alarm functions that alert operators to issues like blade breakage or material misalignment.
