  1. Issues

    Highly efficient production of over 2,000 types of aircraft and rocket airplane parts

    • We looked around the factory to see if there were any abnormalities in the machinery, and searched for ways to effectively increase machine operating rates.
  2. Effectiveness

    Improving work flow lines by connecting with 5S activities
    (Sorting, Setting-in-Order, Shining, Standardizing, Sustaining the Discipline)
    Average machine operating rates increased by 44%

    • With the installation of the AI-equipped MU-8000V-L 5-axis machining center, 5 units were connected using Okuma's Connect Plan; so the factory became an IoT operation.
    • By collecting data, analyzing, and executing, it was possible to take orders for quick delivery parts by taking advantage of pocket times.
    • The number of deliveries, which was 300/month without additional machinery, increased more than 1.5 times to 450-500/month.

Impressions using the Okuma machines

Our first Okuma machine was installed in 2013. At the time, we were considering a multitasking machine to finish aircraft parts that required multiple processes with one chucking, and we installed the MULTUS B300II Intelligent Multitasking Machine. For the factory manager, the “machine rigidity” was the decisive factor. When machining difficult-to-cut materials like Inconel, subtle vibration is a "great enemy" of dimensional accuracy. It also shortens the tool life and naturally increases costs, as well as making tool change times longer. Furthermore, with thermal deformation control, the machining dimensions are stable and work can be done efficiently even when the operator must leave the machine. For those reasons, the shop floor operators are really happy that we chose Okuma.
