June 17 (Wednesday) to June 20 (Saturday), 2026, 10:00 AM to 5:00 PM (last day until 4:00 PM) Makuhari Messe Exhibition Hall 6, Booth No. 16-50 We will send an invitation to those who wish!

We started local machining contracts in 2025. For large equipment that cannot be moved or disassembled, we will "reproduce" the shaft holes "on-site," "accurately," and "quickly" with the "WS series." Please feel free to contact us first. *For heavy machinery repairs, we will introduce you to users.

We will be exhibiting at the 5th Construction and Surveying Productivity Improvement Exhibition, CSPI-EXPO2023! Demonstrations of cutting and welding are also planned. Please take this opportunity to see the actual equipment in operation. *For more details, please download the PDF or feel free to contact us.

We have published a new case study for the portable processing machine WS. In the repair work of the mast top pin boss for large cargo handling machinery (coal handling machine), the site was at a height of 45 meters, making the extensive work challenging. However, by using the WS, we were able to successfully complete the boss diameter expansion work. You can download and view the details of the WS and this processing case from the link below.

We have launched the Daiyō Kōki YouTube channel. We are featuring presentation videos by engineers from Sir_meccanica for each model.
