In the construction machinery industry, where thick plates, large components and high-volume production are the norm, the requirements for processing precision, efficiency and stability are extremely strict. PENTA LASER, as a global leading provider of high-power laser cutting equipment and intelligent manufacturing solutions, has deeply rooted in the construction machinery manufacturing field, providing customized laser processing solutions for many well-known construction machinery enterprises. We focus on solving the pain points of traditional processing methods such as low efficiency, poor precision, high labor cost and difficult processing of large components, and empower the intelligent upgrading of construction machinery manufacturing through a full range of high-performance laser equipment, especially the large-format laser cutting equipment and laser automation systems with material libraries.

In the field of flat plate cutting, which is the core link of construction machinery processing, PENTA LASER has two core models to fully meet the diversified processing needs of the industry. Our high-speed BOLT VII flat laser cutting machine is mainly used for the processing of medium and thin plate components in construction machinery, such as cab panels, small brackets and auxiliary structural parts. It has the advantages of ultra-fast cutting speed and high precision, with a positioning accuracy of up to ±0.05mm and a cutting speed 30% higher than that of traditional equipment. It can realize high-efficiency cutting of complex shapes such as holes, notches and bevels (0-45° one-stop completion), which greatly shortens the processing cycle and ensures the fitting accuracy of subsequent assembly, providing efficient support for the batch production of small and medium-sized components.

As the focus of construction machinery flat plate cutting, our large-format BULL V flat laser cutting machine is tailor-made for the processing of large and thick plate components in construction machinery, which is the core demand of the industry. Construction machinery such as excavators, cranes and loaders often require large-scale thick plate components such as chassis, frames, booms and counterweights, which have the characteristics of large size, thick plate (up to 80mm) and complex structure, and the processing difficulty is extremely high by traditional methods. The BULL V has an ultra-large processing format, which can realize one-time forming cutting of extra-large and thick steel plates, avoiding the trouble of secondary splicing and processing of large components, and greatly reducing the processing difficulty. At the same time, it adopts high-power laser technology, which has a small heat-affected zone and precise cutting precision, effectively avoiding the deformation of thick plates caused by cutting, ensuring the structural strength and stability of large components, and fully meeting the processing requirements of high-strength structural parts in construction machinery. Its excellent bevel cutting performance is more prominent for thick plates: it can stably complete 0-45° bevel cutting of thick plates, with precise control of bevel depth and angle, which perfectly matches the welding needs of large components, improves welding efficiency and ensures welding quality, and has become the core equipment for large-scale component processing in construction machinery enterprises.

For the pipe cutting link in construction machinery processing, our WPC pipe laser cutting machine undertakes the processing of various pipe components, such as construction machinery frame pipes, support pipes, hydraulic oil pipes and connecting pipes. It can flexibly adapt to the cutting needs of pipes of different specifications and shapes, including round pipes, square pipes, rectangular pipes and special-shaped pipes, which are widely used in construction machinery. It adopts an automatic clamping and positioning system, which can realize high-precision cutting of pipe notches, bevels and holes, with smooth and burr-free cuts. Its bevel cutting process has unique advantages: it can realize arbitrary angle (0-45°) bevel cutting of pipes, with high angle precision and consistent bevel quality, which ensures the tight fit of pipe welding joints, reduces welding defects, effectively solves the problems of uneven cutting and loose connection of traditional pipe processing, reduces the subsequent grinding process, and provides a reliable guarantee for the assembly and stable operation of construction machinery pipe components.

As another key demand in the construction machinery industry, the PMW laser automation system with material library has become an important driving force for the intelligent upgrading of construction machinery manufacturing, effectively solving the industry pain points such as high labor dependence, low production efficiency and large human error in traditional processing. The PMW system integrates a high-efficiency material library, automatic loading and unloading equipment, intelligent control system and laser cutting equipment (compatible with BOLT VII and BULL V), realizing the whole-process automated production from material storage, automatic loading, intelligent cutting to automatic unloading and sorting, and can realize 24-hour unattended continuous operation, which greatly improves the equipment utilization rate (thestartuprate of laser cutting machine can reach more than 85%) and production efficiency. The intelligent material library of the system can store a variety of specifications of plates and pipes in a three-dimensional way, saving workshop space, and realizing automatic access and intelligent allocation of materials, avoiding the trouble of manual material handling and storage. The intelligent control system can realize real-time monitoring of the production process, automatic allocation of processing tasks, and seamless docking with the enterprise MES system, realizing order-level production management, which not only reduces the labor cost of enterprises, but also avoids the processing errors caused by manual operation, ensuring the consistency and stability of product quality. For construction machinery enterprises with large batch and multi-variety production needs, the PMW laser automation system with material library can greatly improve production efficiency, reduce production costs, and help enterprises realize the transformation from "manual operation" to "intelligent unattended production", which is highly recognized and widely used in the industry.

From flat plate cutting to pipe cutting, and then to intelligent automated production with material libraries, PENTA LASER has built a full-process laser processing solution for the construction machinery industry, focusing on meeting the core needs of large-format processing and intelligent automation. With high-performance equipment, professional technical support and customized solutions, we help construction machinery enterprises break through the bottleneck of traditional processing, achieve cost reduction, efficiency improvement and quality improvement, and jointly promote the high-quality and intelligent development of the construction machinery industry.
