Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.
Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.
electrolysis process in the electrolytic circuit the electron is flow from the work-piece through the power supply to the tool. the electrolysis process that takes place at the cathode liberates hydroxyl ions (oh-) and free hydrogen. the hydroxyl ions combine with the metal ions of the anode to form insoluble metal hydroxides and material is …
Truing is the process of changing the shape of the grinding wheel as it becomes worn from an original shape, owing to the breaking away of the abrasive and bond. This is done to make the wheel true and concentric with the bore, or to change the …
to diameter. The vessel is charged with the grinding media. The grinding media may be made of hardened steel, or tungsten carbide, ceramics like agate, porcelain, alumina, zirconia. During rolling of vessel, the grinding media & powder particles roll from some height. This process grinds the powder materials by impact/collision & attrition.
The process of metal removal by electro chemical dissolution was known as long back as 1780 AD but it is only over the last couple of decades that this method has been used to advantage. It is also known as contactless electrochemical forming process. The noteworthy feature of …
Electrolytic in-process dressing (ELID) is an efficient method to dress the grinding wheel while performing grinding. In this paper, a fundamental study on the mechanism of the ELID grinding technique is discussed in detail. Several sets of experiments have been performed to determine the optimal grinding conditions.
Electro-chemical grinding (ECG) is a variant process of the basic ECM. It is a burr free and stress free material removal process, wherein material removal of the electrically conductive material takes place through mechanical grinding) process and electro-chemical process.
grinding machines, bufting machines. and reciprocating surface grinding machines. UTILITY GRINDING MACHINES The utility grinding machine is intended for offhand grinding where the workpiece is supported in the hand and brought to bear against the rotating grinding abrasive wheel. The accuracy of this type of grinding machine depends on the

Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode.. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4. The overall reaction is the combination of two electrochemical half reactions.
2. INTRODUCTION Electroplating is a process that uses electrical current to reduce dissolve d metal cations so that they form a coherent metal coating on an electrode. The term is also used for electrical oxidation of anions onto a solid subtrate, as in the formation silver chloride on silver wire to make silver/silver-chloride electrodes.
As my previous article of Grinding Machine, I told, grinding is an important operation in manufacturing industry to get a final product, so for that, we need to know about the grinding wheel and its properties so that we easily choose a right wheel for the right material..
