en.Wedoany.com Reported - Beijing Jingdiao Group from China recently launched three new machine tools, including the JDMR400 vertical five-axis high-speed machining center, the JDHTR800 horizontal five-axis machining center, and the JDSGT400 three-axis high-speed machining center. Several industry customers signed contracts on-site.
The JDMR400 vertical five-axis high-speed machining center is designed for machining product-type parts in industries such as aerospace and humanoid robots. Equipped with a high-torque, high-speed precision electric spindle and a 66-tool magazine, it can complete all processes from heavy-cutting rough machining to high-precision finishing. Taking a humanoid robot structural component as an example, the equipment performs full-feature machining on a solid aluminum block in a single setup, achieving a material removal rate of 90%, with indicators such as concentricity and perpendicularity stably controlled within 20μm. In titanium alloy impeller machining, the blade profile tolerance is better than 0.05mm, and the surface roughness Ra is <0.8μm. The derivative model JDMR400_MT achieves mill-turn composite machining with the aid of a high-speed rotary table (1,600rpm), controlling the coaxiality of superalloy valve body machining within 15μm and achieving a surface roughness of Ra0.25μm.
The JDHTR800 horizontal five-axis machining center targets the machining of large aluminum alloy die-cast parts for Automotive Industry" target="_blank">New Energy Vehicles. It adopts a horizontal layout with a center-through coolant spindle and an in-machine spray chip flushing and filtration system. The spindle extension and retraction acceleration reaches 1.5g, and the G00 positioning speed reaches 60m/min. An engine flywheel housing undergoes multi-feature supplementary machining at 9 angles, with a single part requiring 25 minutes of machining, and the roundness of the Φ400mm inner bore is stably controlled within 10μm.
The JDSGT400 three-axis high-speed machining center is aimed at fields such as precision molds and semiconductors. In a mirror-surface curved test piece case, a PCD tool was used for 9.5 hours of continuous machining, achieving a surface roughness of less than 4 nanometers. In a positional deviation test involving 24 square columns, the positional deviation of each column was controlled within ±1μm. Beijing Jingdiao stated that it will continue to leverage its deep integration advantages in "mechanics, electronics, and software" to empower the high-quality development of China's manufacturing industry.
