Quality Assurance System

Digital Measurement – Coordinate Measuring Machine (CMM)
Unlike general machine parts, blades such as knives are made from curved surfaces, making it challenging to evaluate dimensions.
At Muthous Homura, we use state-of-the-art coordinate measuring machines (CMM) to check whether the product is manufactured according to the design and within the specified tolerance.
*KEYENCE handy probe 3D measuring machine XM-5000, released in January 2022, has been installed.
