No matter how advanced the production equipment is and how skilled the workmanship, a product needs to pass through final quality assurance. In other words, quality assurance both determines and supports a company’s technical level. To ensure stable quality, MIYAKE places great importance on quality inspections after processing and carries out quality assurance using an advanced 3D coordinate measuring machine. In addition, MIYAKE has gear measurement devices that measure the tooth profile, lead, pitch, tooth space runout, CNC gear testing machines that test the meshing accuracy of gears, and machines that measure the surface roughness, form, roundness, and cylindricity of gears. MIYAKE values supplying high-quality gear products to customers in a timely manner.
