machining Most nontraditional micromachining processes are thermal oriented, electrodischarge machining (EDM), laser beam machining (LBM) and electron beam machining (EBM), which may cause thermal distortion of the machined part. Chemical machining and ECM are thermalfree processes, but chemical machining cannot be applied to machine

Precise electrochemical machining (pECM/PECM) is an advanced metal working technique that offers a solution for products that are difficult or impossible to produce through conventional techniques. PECM can be used to process virtually all metals and alloys.
The application of ultrashort voltage pulses between a tool electrode and a workpiece in an electrochemical environment allows the threedimensional machining of conducting materials with submicrometer precision. The principle is based on the finite time constant for doublelayer charging, which varies linearly with the local separation between the electrodes.
ELECTRO CHEMICAL MACHINING Introduction: 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 electrolysis is

Electrochemical machining is a method that finishes the workpiece surfaces by means of anodic metal dissolution. The machining tool is the cathode () that acts under DC current and in the presence of an electrolyte fluid to create the anodic reaction that removes workpiece (+) surface material in a precise

Aim of the presentation Give brief information about electro chemical machining process Show the ECM''s working principles and tools Define the advantages and disadvantages Brief informations about application areas, economics, products and developments.
Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...

Electrochemical machining is a process of a selective dissolution of the anodically connected work piece material submerged in an electrolyte together with an anodically connected tool. Principally electrochemical machining is similar to Electropolishing where the work piece surface roughness decreases due to the conversion of the atoms into ions and their removal from the surface as a result ...
Electro Chemical Machining (ECM) PMPRECISION''s ECM technology is highly suitable for products with a complex 3D geometry in steel and high alloys. ECM is also excellent for products where upperlayer deformations due to more conventional machining techniques are not accepted, as for example is the case with spark erosion. ...
Electrochemical machining (ECM) is a method of removing metal by an electrochemical process. It is normally used for mass production and is used for working extremely hard materials or materials that are difficult to machine using conventional methods.

ElectroChemical Machining (ECM) is the generic term for a variety of electrochemical processes. ECM is used to machine workpieces through the anodic dissoultion of metal. The process is used in aerospace engineering and the automotive, construction, medical equipment, microsystem and power supply industries.
Electrochemical machining (ECM) is a metalremoval process based on the principle of reverse electroplating. In this process, particles travel from the anodic material (workpiece) toward the cathodic material (machining tool). A current of electrolyte fluid carries away the deplated material before it has a chance to reach the machining tool ...
