GMM-X12000 CNC Edge Milling Machine On-Site Processing Case

I. Project Background

A chemical machinery equipment manufacturing and installation company needed to process a large number of steel plates of different specifications for beveling and milling. The plates involved were diverse, including medium-length plates up to 12 meters in length, as well as smaller plates up to 1000mm in diameter, with thicknesses ranging from 8-80mm. The beveling angle needed to be flexibly adjusted to 0-85° (upper beveling) and 0-60° (lower beveling) according to splicing requirements. Some thicker plate components also required processing with a special 90° beveling.

Previously, the company encountered many problems using traditional processing equipment. Feeding medium-length plates relied on manual assistance, which was laborious and resulted in inaccurate positioning; beveling thicker plates required repeated tool adjustments, leading to significant angle errors that affected the subsequent sealing of the equipment; operation required professional programmers, parameter adjustments were time-consuming, and consistency across multiple batches was poor; tool changes and equipment maintenance were cumbersome, frequently causing production interruptions. To overcome the challenges, the company, through its NODHA strategic partner GIRET, implemented a GMM-X12000 CNC Edge Milling Machine.

II. Equipment Application and Processing

1. Equipment Adaptation and Configuration

To meet project requirements, the GMM-X12000 is equipped with a comprehensive adaptation solution: a 7-unit 3500mm roller lifting pusher system forms an electric feeding system, coupled with an automatic stop system, enabling automatic and precise feeding of medium and long plates and small parts, replacing manual pushing; a hydraulic clamping mechanism with 27 pressure feet (22 large + 5 small) can adaptively fix themselves according to the plate size, ensuring vibration-free processing; a semi-enclosed sheet metal protective cover combined with a steel grating pedal ensures operational safety and facilitates real-time observation of the processing status; a horizontal chain plate cutting collection device, in conjunction with the chain plate lifting system and chip cart, achieves efficient chip recycling, keeping the site clean.

2. Core Machining Flow

The GMM-X12000 machine boasts a simple and efficient operation process. Ordinary workers can be trained quickly and are ready to operate it without complex programming or tool setting. For commonly used specifications, eight sets of preset machining parameters can be directly retrieved, and the machine can be started with a single button press.

Utilizing servo drive control technology, the machine's upper and lower spindles can process simultaneously, supporting the simultaneous forming of various bevel types. The processing speed automatically adjusts according to the sheet thickness (0-1500mm/min). Beveling a single side of a 12-meter-long, 30mm-thick sheet takes only 10 minutes. For large-angle beveling of 80mm-thick sheets, the control system automatically calculates the cutting path and activates layered cutting to avoid tool overload while ensuring bevel quality.

3. Maintenance and Support

During equipment operation, the self-diagnostic function monitors the status of each component in real time. Any abnormalities trigger an immediate alarm and display the fault location, allowing maintenance personnel to quickly troubleshoot and resolve the issue. The one-button cutter head positioning function simplifies the blade replacement and inspection process, reducing single tool change time to less than 5 minutes. The automatic lubrication system for key transmission components replenishes lubricating oil regularly and quantitatively, effectively extending component lifespan and reducing maintenance costs.

III. Processing Results and Customer Feedback

1. Improved Processing Efficiency

Compared to traditional equipment, the GMM-X12000 reduces processing time per sheet and increases production capacity. The automatic feeding system reduces the need for auxiliary operators, and small sheet processing eliminates the need for additional positioning fixtures, lowering labor costs.

2. Higher Machining Precision

The dual protection of servo drive and hydraulic clamping ensures that the bevel angle error is controlled within ±0.5°, and the dimensional accuracy fully meets the project's technical requirements. Welding joint fit is significantly improved, with the weld pass rate increasing from 91% to 99.6%. Parameter storage ensures consistency across multiple batches, completely resolving previous specification fluctuation issues.

3. More Convenient Operation and Maintenance

Automatic lubrication and convenient tool changing designs reduce the average monthly maintenance time, ensuring consistent equipment uptime.

4. Customer Feedback

The GMM-X12000 perfectly meets the company's diverse and high-precision machining needs, with processing efficiency and accuracy far exceeding expectations.
