Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape. [1][2] Other names for chemical etching include photo etching, chemical etching, photo chemical etching and photochemical machining.
Milling is the process of machining using rotary cutters to remove material [ 1 ] by advancing a cutter into a workpiece. This may be done by varying directions [ 2 ] on one or several axes, cutter head speed, and pressure. [ 3 ] Milling covers a wide variety of different operations and machines, on scales from small individual parts to large ...
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...
Crushing, a form of comminution, one of the unit operations of mineral processing. Mineral processing is the process of separating commercially valuable minerals from their ores in the field of extractive metallurgy. [1] Depending on the processes used in each instance, it is often referred to as ore dressing or ore milling.
Photochemical machining. Photochemical machining (PCM), also known as photochemical milling or photo etching, is a chemical milling process used to fabricate sheet metal components using a photoresist and etchants to corrosively machine away selected areas. This process emerged in the 1960s as an offshoot of the printed circuit board industry.
[12] [13] Ball milling is a widely used process in which mechanical force is used to achieve chemical transformations. [14] [15] It eliminates the need for many solvents, offering the possibility that mechanochemistry could help make many industries more environmentally friendly.
Electrochemical machining (ECM) diagram. Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and for working extremely hard materials, or materials that are difficult to machine using conventional methods. [1] Its use is limited to electrically conductive materials.
Toledo Pharmacal Company from Toledo, Ohio seen in 1905. Pharmaceutical manufacturing is the process of industrial-scale synthesis of pharmaceutical drugs as part of the pharmaceutical industry. The process of drug manufacturing can be broken down into a series of unit operations, such as milling, granulation, coating, tablet pressing, and others.
