DJ1000C Full-Auto CNC Band Saw for H-Beams

Product Overview

The DJ1000C is an industrial-grade full-auto band saw built for heavy structural steel processing, specializing in H-beams up to 1000×400mm—ideal for skyscrapers, long-span bridges, and offshore structures. Its key advantages include 60% higher productivity than semi-automatic saws, ±0.3mm positioning accuracy, and ability to handle high-tensile steel up to 790 MPa.

Product Features

Ultra-Large Cutting Capacity

The machine’s reinforced cast-iron frame supports cutting of H-beams, I-beams, and box sections with maximum dimensions of 1000mm in height and 400mm in width. The bi-metal band saw blade, available in lengths up to 7200mm, operates on precision-guided roller bearings that maintain blade stability even during extended cuts through thick-walled structural steel.

High-Power Performance

A 22 kW main motor delivers exceptional cutting force, enabling processing of high-tensile strength steels up to 790 MPa—including weathering steels and high-strength low-alloy grades commonly specified in critical infrastructure projects. The variable blade speed system adjusts from 20 to 150 m/min based on material thickness and hardness, with automatic optimization algorithms that select optimal cutting parameters.

Advanced Automation System

The fully automated material handling system includes a powered infeed conveyor of 15 meters length, servo-driven positioning with ±0.3mm accuracy, and automatic discharge to a sorting conveyor. The hydraulic clamping system applies adjustable pressure from 80 to 400 kN, securely holding large workpieces without deformation during cutting. An automatic chip removal system keeps the cutting zone clear during extended production runs.

Intelligent Process Management

The industrial CNC controller features a 12-inch touchscreen interface with 3D simulation capabilities, allowing operators to preview cutting sequences before production. The system stores up to 500 cutting programs and includes nesting software that optimizes material utilization to reduce waste by up to 25%. Real-time monitoring of blade temperature and wear triggers automatic input rate adjustments to prevent blade damage.

Applications

Mega-Construction Projects

In high-rise building construction, the DJ1000C processes massive H-beam sections for columns, girders, and transfer structures that form the skeleton of supertall buildings. Its precision ensures proper fit during the welding and bolting phases of construction.

Long-Span Bridge Fabrication

For highway and railway bridges with spans exceeding 100 meters, the machine cuts heavy H-beam and box girder components requiring exceptional dimensional accuracy for load distribution and structural integrity.

Offshore Structures

In offshore oil platforms and wind turbine foundations, the machine processes thick-walled structural steel components that must withstand extreme environmental conditions and corrosive marine environments.

Heavy Industrial Facilities

Manufacturing plants for power generation, metallurgy, and chemical processing utilize the DJ1000C to produce large structural components for equipment frames, support structures, and material handling systems.

FAQ

What is the production capacity of the DJ1000C per shift?

When processing 8-meter H-beams of 600×300mm cross-section (S355 steel), the machine can produce approximately 180–220 cut pieces per 8-hour shift, depending on cut lengths. This represents a 75% increase over conventional large-capacity band saws.

What blade type is recommended for different materials?

For standard structural steels, we recommend bi-metal blades with 4–6 TPI (teeth per inch). For high-tensile steels over 690 MPa, carbide-tipped blades with 3–4 TPI extend blade life by up to 200% compared to standard bi-metal blades.

How long does blade replacement take?

The quick-change blade system, featuring tool-less tension adjustment, allows experienced operators to replace and properly tension a blade in under 15 minutes. The machine includes automatic blade tension verification before cutting begins.

Can the machine integrate with material tracking systems?

Yes, the CNC controller supports Industry 4.0 protocols for integration with ERP and MES systems. Each cut piece can be automatically identified with dimensional data and material information, enabling full traceability from raw material to finished component.
