Product Description

The CNC Beveling Machine BM38-6 for H-Beams with PLC Control represents the pinnacle of structural steel fabrication technology. When you stand beside this robust machinery, the sheer weight of its 5,000-kilogram solid steel chassis conveys immediate stability, effectively absorbing and minimizing vibrations even during the most aggressive, high-speed milling operations. The smooth, rhythmic hum of the 7.5 kW axis motors engaging the indexable carbide inserts against thick steel webs speaks volumes about its relentless power and precision. Every surface, from the linear rolling guides to the heavy-duty conveying roller ways, is meticulously treated for maximum wear resistance, offering a sleek, industrial finish that easily withstands the harsh, abrasive environments of metalworking facilities. The scent of specialized cutting fluids and freshly milled heavy steel accompanies a process that is as visually impressive as it is mechanically sound.

By automating the complex beveling process, this equipment completely eliminates the physical strain, safety hazards, and time-consuming bottlenecks traditionally associated with manually turning massive H-beams. Operators simply input the required dimensional data into the highly responsive, glare-resistant touch-screen panel. From there, the machine's intelligent PLC system takes full command, flawlessly executing complex arc notches, straight-line bevels, and precise end-face milling. This sophisticated level of automation not only drastically accelerates your production timelines but also guarantees a uniform, flawless finish on every single beam. The resulting pristine metal surfaces ensure that your structural connections are structurally sound, perfectly aligned, and fully optimized for subsequent high-integrity welding phases.

Key Features & Highlights

Investing in the BM38-6 means equipping your facility with a machine designed to resolve complex fabrication challenges. By focusing on intelligent design and robust mechanics, this equipment directly improves your operational output and reduces overhead costs.

Elimination of Manual Material Handling: Integrated infeed, outfeed, and transmit conveyors with adjustable speed and frequency converters allow the machine to mill both ends without ever needing to physically turn the massive H-beams around. This drastically reduces crane usage and prevents workplace injuries.
Superior Milling Versatility: Each of the two columns is equipped with a horizontal milling head featuring three different mills. This allows for simultaneous milling of both ends, effortlessly beveling the flange and web to create precise arc notches and straight-line profiles.
Intuitive Data-Driven Operation: The transition from one beam specification to another is completely seamless. Operators simply input the new dimensional data into the computer system, and the machine automatically adjusts its longitudinal and transverse slipways to accommodate the new end face.
Unyielding Clamping Stability: Machining heavy steel requires absolute rigidity. This machine utilizes flange inside positioning, float clamping for the web via two up-down jaws, and powerful web pressing driven by an air over hydraulic booster, ensuring zero workpiece shift during high-torque milling.

Advanced Processing & Multi-Industry Applications

The true value of the BM38-6 lies in its comprehensive approach to industrial problem-solving. From its core components to its broad application spectrum, every aspect is engineered to deliver reliable, high-yield results for large-scale procurement projects.

Processing Efficiency & Automation Degree

Time is a critical asset in structural fabrication. This equipment is outfitted with a comprehensive conveying roller system (including a 5000mm off-line roller way) managed by variable frequency drives. Because the H-beam does not require flipping to mill both ends, the continuous flow of the assembly line is preserved. The PLC system handles all complex calculations and positioning, meaning that once the data is entered, human intervention is minimized, and throughput is maximized.

Clamping Positioning & Machining Accuracy

Precision at the millimeter level is non-negotiable for load-bearing structures. We achieve this through a multi-tiered clamping mechanism. The system locates the beam via the inner flange, while dual vertical jaws provide floating clamping for the web. Furthermore, an advanced air over hydraulic booster applies up to 10.8 MPa of oil pressure to firmly press the web. This guarantees that heavy, cumbersome workpieces remain completely immobilized, resulting in flawless, repeatable milling accuracy.

Core Components & Equipment Longevity

Downtime is costly, which is why the BM38-6 is built with an uncompromising selection of premium imported components. The linear rolling guides, ballscrews, reductors, touch-screens, frequency converters, photoelectricity encoders, and the PLC system are sourced from globally recognized brands. This commitment to quality prevents premature wear and tear, ensuring that the machine maintains its high performance and reliability even after years of continuous operation in harsh environments.

Multi-Scenario Application & Adaptability

This beveling machine is an indispensable asset across various heavy-duty sectors:

Building Steel Structure: Perfect for processing the load-bearing H-shaped frames of multi-story factories and high-rise commercial buildings, ensuring node connections are exact and structurally sound.
Bridge Engineering: Essential for on-site assembly of large-span highway and railway bridges. The ability to complete end notches and web arc grooves in a single pass significantly accelerates installation efficiency.
Municipal & Infrastructure: Highly capable of churning out large volumes of standardized H-beams required for elevated road supports and underground pipe gallery frameworks through continuous automated processing.
Heavy Machinery Manufacturing: Delivers the high-strength, precise connections demanded by the load-bearing frames of massive industrial equipment, such as port cranes and mining machinery.

Below are detailed answers to common technical and operational inquiries regarding the BM38-6 CNC Beveling Machine, designed to assist procurement specialists and engineering teams in their evaluation process.

1. How does the float clamping mechanism enhance the milling accuracy of the H-beams?

The float clamping system utilizes two up-down jaws that adapt to slight dimensional variations inherent in raw structural steel. By combining this with inner flange positioning and an air over hydraulic booster, the machine secures the web firmly without distorting the beam's natural shape. This ensures the milling head engages the steel at the exact programmed angle and depth, resulting in highly accurate and repeatable bevels and notches.

2. What are the specific power requirements and environmental tolerances for installation?

The machine requires a robust three-phase, four-wire power system operating at 380V AC with a frequency of 50 Hz. It is designed to handle voltage fluctuations of ±10%, ensuring stable operation even in industrial grids with minor power inconsistencies. Environmentally, the equipment is engineered to perform optimally within a temperature range of 0℃ to 40℃, making it suitable for the vast majority of indoor fabrication facilities.

3. Can the machine handle customized arc notches and complex beveling tasks?

Yes. The BM38-6 is equipped with a highly adaptable PLC control system and dual horizontal milling heads, each holding three different indexable carbide insert mills. Operators can easily input custom dimensional data (such as specific C max values up to 38mm, or precise R and r radii) into the touch-screen. The machine will automatically adjust the longitudinal and transverse slipways to execute complex arc notches and straight-line bevels exactly to your project's specifications.

4. How do you guarantee service and minimize downtime for international clients?
