Bore polishing

Bore polishing

Bore polishing is available on tubes with 0.1 mm at minimum inside diameter, 0.01 μm at maximum surface roughness, and 700 mm at maximum length (For curved tubes, the maximum length is 300 mm). Even drawn parts, such as curved tubes, taper-shaped parts and nozzles, can be polished with our technique. We deal in difficult-to-machine materials such as pure titanium and titanium alloy as well as SUS.
Please feel free to ask us for your specific requests.

・ Maximum length: 700 mm for straight tube, 300 mm for curved tube
・ Minimum inner diameter: 0.1 mm
・ Materials: SS, titanium (pure titanium, titanium alloy), copper
・ Minimum surface roughness: Ra 0.05 (Ra 0.01 for special specification)

Bore polishing on swaging tube

Swaging a tube can cause creases inside the tube so that the roughness of the inner surface sometimes is degraded. We have established the technique that can remove these creases to obtain a smoother surface.
Bore polishing can prevent contamination to the utmost limit for accurate and stable data acquisitions, which is suitable for medical/analytical instruments for highly precise analysis.
