The GLAB high-rigidity horizontal machining center stands out in terms of "extreme stability". The equipment features an integrally formed base with an innovative high-rigidity inverted T-shaped box structure, combined with a large-span track design. This ensures the most stable support rigidity even under conditions of rapid axial feed. The column adopts a moving frame double-wall low-center-of-gravity structure, effectively suppressing cutting vibrations and ensuring stable operation during heavy-duty cutting.
Regarding the rotary table, users can choose configurations with a numerical control indexing accuracy of 0.001° or a precision ratchet tooth plate indexing accuracy of 1° according to their needs, achieving precise rotary indexing positioning to meet the requirements of high-precision machining. The spindle box features a lightweight and high-rigidity symmetrical structure, which not only reduces its own deformation and thermal deformation but also has excellent dynamic response performance.
All three axes are equipped with ultra-high-rigidity roller-type linear guides, combining the heavy-cutting rigidity of hard guides with the fast movement and low wear of linear guides, resulting in a significant improvement in the machine's rigidity and controllability. In addition, key contact surfaces such as the base, column, worktable, and screw fixing seats are all processed by precision hand scraping to ensure optimal assembly accuracy, structural strength, and balanced loading.
In terms of "comprehensive supply and demand", GLAB adheres to strict quality control from the source. All cast iron structural components are optimized through 3D design and finite element analysis, and are processed by an alternating process of tempering and aging to completely eliminate internal stress, thus significantly improving the overall motion rigidity and accuracy retention of the machine tool. Strict part and assembly inspection processes, combined with advanced inspection equipment and precision assembly technology, ensure that each piece of equipment can achieve optimal working accuracy.
The "high-power spindle" is another highlight of GLAB's equipment. Its high-precision spindle has a standard speed of 6000 rpm and is equipped with a spindle air curtain protection device to effectively ensure the high precision and long life of the spindle. Users can also choose a 3000-rpm version. The spindle is driven by a high-power (15/18.5kw) dual-winding surplus servo motor, with a torque of up to 210 NM (up to 420 NM when the 3000-rpm option is selected). The worktable, positioned by a high-precision gear plate, has a positioning accuracy of ±5″ and a repeat positioning accuracy of ±3″, demonstrating excellent performance.
In terms of "high structural rigidity", the overall machine design prevents the generation of overturning moments throughout the entire stroke. The base casting is processed using high-precision five-face gantry machining technology. With a single clamping, processes such as five-face milling, drilling, and tapping can be completed, greatly reducing clamping errors and improving processing accuracy. The lead screw adopts a set of 60° angular contact ball bearings, with a double-support and pre-tensioned design to further ensure transmission accuracy and reliability.
In summary, the GLAB high-rigidity horizontal machining center demonstrates industry-leading performance in structural design, material processing, spindle performance, and overall rigidity. It is not only suitable for heavy-duty cutting, high-precision indexing, and complex part processing but can also maintain stable accuracy during long-term high-load operation, significantly improving users' production efficiency and product quality.
In the future, with the in-depth advancement of intelligent manufacturing and Industry 4.0, high-rigidity, high-precision, and high-stability machining centers will become the core force in high-end equipment manufacturing. With its solid technical accumulation and unremitting innovation spirit, GLAB is expected to continue to make breakthroughs in domestic and international markets, providing strong support for promoting the transformation and upgrading of the manufacturing industry.
