The ultra-wide integral bed is reinforced with finite element analysis (FEM) optimized ribs to endure heavy cutting forces and sustain long tool life. A potent spindle motor up to 15 kW combined with a 12/16-position servo tool turret facilitates multi-tool operations with minimal downtime. Specifications include a maximum swing diameter of 730 mm and machining lengths reaching 2050 mm, ensuring compatibility with demanding workpieces. The structural design parallels high-performance gantry cnc systems, providing enhanced stability and repeatability for precision machining tasks.

Industrial Applications Enhancing Production Efficiency

Suitable for applications in automotive, aerospace, and general heavy industry, the HTL18D series effectively handles prototype validation, long-shaft machining, and high-load cutting scenarios. This solution enables production facilities to compactly integrate large turning operations within existing gantry mill and cnc gantry milling machine environments, improving the workflow of complex shaft and cylinder components manufacture. Additionally, the programmable tailstock and robust turret support repetitive high-precision tasks, facilitating long-run production with tight tolerances. The system’s adaptability ensures optimized cycle times in industrial settings demanding a balance between scale and accuracy.

Machine Characteristics The HTL series is a large-scale CNC turning center, specially designed for large and long shaft products. It features an ultra-wide integral bed, a 45° inclined saddle, and large-sized roller linear guides and￠50mm precision-grade ball screw. This provides sufficient machine rigidity, enabling it to handle various machining tasks and maintain bed accuracy for a long time. By applying finite element analysis (FEM), the shape and position of the reinforcing ribs in the castings are optimized to achieve the best bed strength, making the bed structure more suitable for heavy cutting and extending the tool's service life.
