The YCM NFX400A is a compact simultaneous 5-axis CNC vertical machining center from Yeong Chin Machinery, a Taiwanese builder known for rigid Meehanite castings and dependable machine construction. This 2021 unit pairs X / Y / Z travels of 25.6 x 20.47 x 18.9 inches with an A/C trunnion table offering +30 / -120 degree A-axis tilt and 360 degree C-axis rotation. The 13.8 inch diameter table is rated for 441 lbs and accepts workpieces up to 15.8 inches in diameter by 12.2 inches tall, making the NFX400A well suited to impellers, manifolds, medical implants, aerospace brackets, and other complex parts that benefit from five-sided or full 5-axis contouring in a single setup. The 40 taper spindle is rated to 12,000 RPM, and this machine is equipped with a 30 HP spindle package. Rapid traverse reaches 1,417 ipm on X, Y, and Z. Tooling is handled by a 40-tool chain magazine with an arm-type changer accepting tools up to 2.99 inches in diameter, 11.02 inches long, and 13.2 lbs. The Fanuc Series 31i-Model B5 control provides simultaneous 5-axis capability for TCP and tilted work plane programming. Equipment on this unit includes linear scales on X/Y/Z with rotary scales on A and C, a Chip Blaster 1000 PSI high pressure through-spindle coolant system, a Royal Mist collector, a Jorgensen chip conveyor, a spindle chiller, and a 5-axis workholding package.
The NFX400A builds on YCM's earlier NFX380A compact 5-axis platform. Where the NFX380A was commonly configured with a 30-tool magazine, this NFX400A carries a 40-tool chain magazine, giving shops more room to keep 5-axis tool libraries loaded across multiple jobs. YCM designed the NFX400A around an extra-wide column and base for added stability during simultaneous 5-axis cutting, and this unit adds linear and rotary scales, high pressure through-spindle coolant, and mist collection. Compared with the NFX380A, the NFX400A gives buyers a more fully equipped, current-generation 5-axis cell with the Fanuc 31i-B5 control, positioned for repeatable multi-face work in fewer setups.
