Kurota's Story: The 300 Million Hole
The spirit of not giving up and relentless effort have created KUROTA's unique technology (equipment), which continues to be passed down to this day!
Years ago, when I was a manufacturing leader, I heard that the domestic master cylinder pistons were expanding their sales channels overseas. I was excited about the big opportunity and had high expectations for increased sales. However, I also felt a twinge of anxiety about the newly launched pistons, and soon that anxiety proved to be justified. In the early stages of development, the precision of the jigs was poor, leading to frequent occurrences of punches chipping against the jigs. This issue was resolved by improving the precision of the jigs, which eliminated the chipping. However, the fact remained that as soon as one problem was solved, another would arise, and I was daily tormented by this back-and-forth loop of challenges. *For more details, please refer to the related links.
