KBK Engineering | Kurashiki, Okayama, Japan | Entrust us with maintenance and service for rotating machines

Company Profile

Company profile, major facilities, access map

In today’s world, the plant engineering industry requires assurance of maintenance and service because once an accident occurs, there is just too much to lose. Therefore, we make it our job to solve the following problems:

  • The problem of transferring technical strengths in line with the current mass retirement of Japan’s highly-skilled baby boomers.
  • Due to manufacturer discontinuation of production and organization scale-downs, the large number of rotating machines in operation, without expectations for after-sales service, are left unchanged.
  • Adequate repairs cannot be made because of reductions in maintenance and service budgets, repair time-frames, etc.
  • Even self-owned mechanical equipment is in a virtual state of so-called “dependence on others.”

In consideration of such a dire situation, we, as a team of mechanical engineers, started our company with the aim of becoming “the family doctor of high-speed rotating machines.” Integrating diagnostic technology as a nurse practitioner, condition assessment technology as a diagnostician, engineering technology as a surgeon, and maintenance and service technology as a healthcare management specialist, we take pride in our hands-on approach to machine repair just like people care.
As a specialist in repairs for high-speed rotating machines, our employees will continue to further efforts in acquiring maintenance and service knowledge and improving assembly skills in order to accurately respond to customer demands.
