6 Dos and Don’ts of Ferric Chloride Etching - Chemcut

Modern steelmaking processes can be divided into three steps: primary, secondary and tertiary. Primary steelmaking involves smelting iron into steel. Secondary steelmaking involves adding or removing other elements such as alloying agents and dissolved gases. Tertiary steelmaking involves casting into sheets, rolls or oth… WebAlso known as photo etching, photochemical milling, and chemical milling, photochemical machining (PCM) is the process of fabricating sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960’s and can produce highly complex parts with extremely accurate detail. An ... WebPolycrystalline cubic boron nitride, CBN, is a cutting tool material with excellent hot hardness that can be used at very high cutting speeds. It also exhibits good toughness and thermal shock resistance. Modern CBN grades are ceramic composites with a CBN content of 40–65%.
