Chemical polishing for ultra-fine bores and complex internal geometries
Chemical polishing treats complex internal surfaces in a single operation. Ultra-fine bores and bellows interiors, however, have long been considered difficult to process: the chemistry is hard to deliver and act uniformly across such geometries. We developed our own cleaning and chemical polishing equipment specifically for this domain, achieving uniform internal polishing on shapes that electropolishing cannot fully address. More than 20 years of chemical polishing experience, offered as finished products, contract processing and technology transfer.
Products & services — our own technology
Our core products and services, built on chemical polishing technology.
UHP Capillary Tubing
Ultra-fine stainless steel capillary tubing, 0.2–1.0 mm ID. Internal chemical polishing achieves Ra 0.17 µm together with an improved Cr/Fe ratio, and supports large-lot production at many times the throughput of electropolishing.
Contract Chemical Polishing
Chemical polishing of customer-supplied material. Capillary tubing, precision components, medical needles and similar parts are handled under process control grounded in more than 20 years of experience.
Bellows interiors are also supported, with a track record on geometries long regarded as difficult to polish.
UHP Tubing (long lengths, larger bores)
Technology transfer / partner production
UHP tubing in 3.18 mm and 6.35 mm ID, in lengths up to 6 m, for high-purity piping in semiconductor equipment. We have supplied equipment and provided technical guidance to overseas operations, and welcome enquiries regarding partner production in Japan and the United States.
About our chemical polishing technology
The fundamental advantage of chemical polishing is that it does not require each workpiece to be individually fitted to an electrode, as electropolishing does. The chemistry can be brought into contact with internal surfaces of complex shape.
Inside a 0.2 mm capillary or a bellows, however, delivering the chemistry and having it act uniformly is difficult—which made that advantage hard to realise in practice.
Building on more than 20 years of chemical polishing experience, we independently developed cleaning and polishing equipment for these geometries—extending the shape-handling capability inherent to chemical polishing into the domain of ultra-fine and hard-to-process internal surfaces.
Other products handled
Products supplied through sourcing, without chemical polishing.
Precision Metal Components (build to print)
Machining of precision metal components to customer drawings. Parts that do not involve chemical polishing, such as optical components, are handled through machining partners with whom we have worked for many years.
HPLC Empty Column Hardware & Accessories
Empty column tubes for analytical and preparative use, slurry packers, frits, guard columns and related accessories. Sourced from a specialist manufacturer in China with whom we have a long-standing relationship; KAMEHA handles supply and technical support.
Technical consultation and quotations
We welcome enquiries on feasibility and specifications, and provide quotations based on your drawings. Ultra-fine bores and complex internal geometries are exactly what we would like to hear about—please get in touch.
