Electrolytic Machining Technology Parameters
Electrolytic machining (EM) is an electro-chemical material removal process which is used to remove metal from a workpiece in a controlled manner. It is used mainly to finish small, accurate components in alloy materials such as nickel, cobalt, titanium, and stainless steel. This article discusses the technology parameters of EM machines and its application in modern industry.
Electrolytic machining involves the use of an electrolyte which can be either a liquid, gel or paste. This electrolyte is usually a sulfuric acid or a alkaline solution that acts as a conductor of electricity, allowing a current to flow from the work piece to the electrolyte. The current reactivity to the patterns created results in chemical reactions and the metal being removed from the workpiece.
The most important factor in obtaining the desired final finish and accuracy is the control of the currents. The current in electrochemical machining depends upon various parameters such as electrolyte type, concentration, temperature and pH. It is also important to consider the types of electrodes used to create the electromechanical pattern. These can be either conductive or platinum-family metal electrodes.
The EM process also involves controlling the volume of material to be removed by regulating the current density. The current density is defined as the number of amps per square millimeter of the exposed area of the workpiece. The current that is applied will depend on the workpiece being machined. It is important to note that when the current density is increased, it can result in shallow grooves being created as the metal is removed.
The process is usually conducted with the help of a computer-controlled unit. This unit will collect data on the parameters mentioned above and make adjustments to the current accordingly. This ensures that a consistent finish is created each time the machine is used.
The EM process is used in several engineering and technical processes, including the creation of components such as machined parts, tooling, and precision industrial parts. It is also used to create surface finishes on items such as optical lenses, eyeglasses, and automobile windows. EM machines have been used extensively in the medical industry, primarily to finish implants and medical devices. Finally, EM machines are also used to create intricate patterns on items such as jewelry and trophies.
Overall, the application of electrochemical machining technology is essential for producing accurate parts in modern industries. It requires the correct combination of current, temperature, and pH values to produce quality results. The EM process is becoming more widely used for a variety of machining and finishing processes. EM technology provides consistent results and is an excellent and cost-effective method for producing precision parts for a variety of applications.
