KAMEHA Co.,Ltd Product Lineup

Electropolishing (EP) requires an electrode inside the workpiece. Mechanical polishing (MP) reduces roughness but leaves the surface chemistry unchanged. For 0.2mm ID capillary tubing and bellows interiors, neither method works. KAMEHA is a technical trading company specializing in chemical polishing (CP) of ultra-fine and geometrically complex internal surfaces. Because CP works wherever the chemistry reaches, we developed our own dedicated equipment to apply it to bores that other methods cannot access. Features ■ Internal surfaces down to 0.2mm ID (capillary tubing) ■ Bellows and other complex geometries where electrodes cannot be inserted ■ Internal surface roughness: Ra 0.17µm (measured) ■ Improved Cr/Fe ratio for enhanced corrosion resistance — an effect mechanical polishing cannot produce ■ Material: SUS316L (VIM+VAR double vacuum melted) ■ 11-step in-house process, from ultrasonic degreasing through chemical polishing, passivation, multi-stage rinsing, and cleanroom packaging ■ Contract polishing available for customer-supplied parts Please download the PDF or contact us for details.
