Surface finishing of additively manufactured stainless steel surgical instruments

The new powder coating line is more than metres in length and uses a nanotechnology pre-treatment process that is based on zirconium conversion. The deburring process for high-precision components of car fuel systems has to meet high standards. A leading manufacturer of injection-moulded parts of this kind uses a blast machine for deburring purposes that combines turbine and injector blasting to produce excellent results and good energy efficiency. A new compact tumble belt blasting machine has been developed for a high throughput of small parts. It combines the compact design of batch processing machines with the advantages of continuous operation. This simplifies and speeds up the surface finishing process for cast components.

Additive manufacturing AM has the potential to revolutionise the fabrication of complex surgical instruments. However, AM parts typically have a higher surface roughness compared to machined or fine cast parts. High surface roughness has important implications for surgical instruments, particularly in terms of cleanliness and aesthetic considerations. In this study, bulk surface finishing methods are described to produce end-use selective laser melting parts. A sample coupon was designed to systematically evaluate different finishing techniques.

Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. An unfinished surface is often called mill finish. Mechanical processes may also be categorized together because of similarities the final surface finish. Mechanical finishing processes include: [3]. The use of abrasives in metal polishing results in what is considered a "mechanical finish".

Surface finishing processes

Surface finish is an important element in any specification of stainless steel regardless of the intended use. For those applications where appearance is important, finish is a design element and must be specified. In non-decorative applications the surface finish may have implications for friction, wear, maintenance or corrosion resistance and must, therefore, also be carefully chosen and clearly specified.

Superfinishing , also known as micromachining , microfinishing , [1] and short-stroke honing , is a metalworking process that improves surface finish and workpiece geometry. Superfinishing, unlike polishing which produces a mirror finish, creates a cross-hatch pattern on the workpiece. The superfinishing process was developed by the Chrysler Corporation in

Может быть, он сражается с вирусом. Джабба захохотал. - Сидит тридцать шесть часов подряд. Бедняга. Наверное, жена сказала ему не возвращаться домой. Я слышал, она его уже достала.

Женщина, наклонившаяся над умирающим, очевидно, услышала полицейскую сирену: она нервно оглянулась и потянула тучного господина за рукав, как бы торопя. Оба поспешили уйти. Камера снова показала Танкадо, его руку, упавшую на бездыханную грудь. Кольца на пальце уже не. ГЛАВА 118 - Это может служить доказательством, - решительно заявил Фонтейн.  - Танкадо избавился от кольца.

 Я знал, что он меня не слушает. Вот так и рождаются слухи. Я сказал ему, что японец отдал свое кольцо - но не. Да я бы ничего и не взял у умирающего. О небо.
