Evaluation of the shape of the FRP hole processing drill manufactured in-house and the X-ray CT assessment of the processed object.

Evaluation of the shape of the FRP hole processing drill manufactured in-house and the X-ray CT assessment of the processed object.

Compare and evaluate the conditions before and after processing using an in-house manufactured φ15mm drill for FRP and a commercially available drill through visual inspection and non-destructive testing!

This document is a technical report that evaluates the characteristics of drill shapes after processing, using the example of hole processing in FRP. It includes quantification of the features of the processed drill shapes conducted in-house, as well as a quantitative comparison of these shapes with commercially available drills. Additionally, it assesses the validity of the shapes through FRP processing. In the evaluated range, while no superiority was recognized between the commercially available drills and the modified in-house drills for FRP processing, it was confirmed that the shape of the in-house processed drills contributes to extending the tool life. This result holds significant importance from the perspective of extending tool life. [Contents (Evaluation Preparation, Methods, and Results)] ■ Preparation of evaluation drills ■ Shape inspection of evaluation drills ■ Production of flat plates for processing evaluation ■ Hole processing using various drills ■ X-ray CT measurement *For more details, please download the PDF or feel free to contact us.

Mountainous area megasolar power generation

Mountainous area megasolar power generation

Achieving low cost! Introduction of hollow cable installation solar power generation system.

Our company has developed a completely different method of "mountainous mega solar power generation" compared to traditional solar power generation on mountains and slopes. Essentially, it is a facility that achieves low costs and is installed in the air rather than on the ground. The maximum installation rate of solar panels is about 90% (recommended 50%), and the maximum installation angle is about 30 degrees, allowing for the installation of hollow curved surfaces. 【Features】 ■ Achieves low costs ■ Air installation method ■ Maximum installation rate: approximately 90% (recommended 50%) ■ Maximum installation angle: approximately 30 degrees ■ Capable of hollow curved surface installation *For more details, please refer to the PDF materials or feel free to contact us.

Rainwater tank (for toilet flushing) Model number M4214PE-TT

Rainwater tank (for toilet flushing) Model number M4214PE-TT

Limited resources How do you read "rainwater"?

As a manufacturer of gutters, we have focused on quickly draining rain that falls on residential roofs. This is precisely the drainage of "usui." Originally, rain is very clean water and the source of all the freshwater we typically use, such as rivers and wells. Instead of discarding this beautiful "rain," we have created a product that transforms it into "amamizui" by utilizing it as water for daily living. Transforming rain, the source of all freshwater, pure rain, and the blessing of nature, from "usui" to "amamizui."
