The underlying strength of the Group’s companies

This is what conservation is all about

On a Friday in March, a call came in from a company in the prefecture. The factory was unable to operate due to high vibrations in the exhaust air machine, which is important for the manufacturing process. The company said that this was a big problem for them and that they had to stop production. They asked us to remove the shaft and bring it in on Monday so they could deal with the problem. It is too late to bring it in on Sunday evening and Monday morning, and we want to bring it in now because the shaft came off early. It is an emergency situation, so I go to the company and pick up the axis. The technical officer came to the office with me and I listened to the explanation on the spot.

On Monday morning, the Kurashiki Boring personnel and relevant personnel are briefed in front of the actual product. The work was immediately dismantled and inspected and found to be repairable by thermal spraying. Repair parts were determined to be four locations, a keyway and a threaded part. A request is made on the same day, and the machine is brought to KBK in the evening of the same day. A field balancing of the impeller is also decided and preparations are started. At the same time, a request is made for the production of the necessary additional parts, and confirmation of the replacement parts is started in preparation for assembly. When we looked in later that day, KBK had repaired the requested shaft. Thank you very much.

The repair of the axis is completed on Wednesday evening. Assembly begins immediately and is completed at midnight the same day, and is immediately handed over to the customer who was on standby.

Repairs to be completed and assembled in two days and restored in five days

Thanks to the cooperation between KBK Eng and Kurashiki Boring and our network, and of course the cooperation with the customer, the entire process from repair to restoration could be completed in a short period of time. This is an example of how the items to be inspected and the parts to be observed when they were brought in, the arrangement and securing of the necessary additional parts, KBK’s repair response, KBK Engie’s assembly response and KBK’s on-site field response all functioned well and enabled the repairs to be carried out quickly.
