You can choose a wide selection of metal surface finishing services after machining at Tuofa CNC machining manufacturer to improve the parts appearance, surface smoothness, corrosion resistance and other performance of your CNC machined parts.


  • Painting: refers to an altering surface finishing process, spraying paint, pigment, or color to a solid surface as a colored protective layer, and can be done on metal or non-metal CNC machined components of any shapes, usually applied on aluminum, stainless steel, and steel alloy parts. The purpose is to improve aesthetic appearance and prevent corrosion or oxidation.


  • Passivation: a common chemical surface treatment method for steel and stainless steel, to remove ferrous contaminants or use a light coat of protective material to create a shell for enhancing the corrosion resistance or reducing the chemical reactivity.


  • Electroplating/Plating: a process of using an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode, to change the properties of the machining metal surface or build up thickness for undersized parts.


  • Powder coating/Powder coat: a functional and decorative finish, which is applied as a free-flowing, dry powder, employs electrostatically and then cured under heat, to create a hard finish that is tougher than conventional paint. The main applications include household appliances, aluminum extrusions, drum hardware, automobile, motorcycle, and bicycle parts.


  • Anodizing/Anodized: an electrolytic passivation process of forming a thin layer of aluminum oxide on the exterior of aluminum CNC machined parts to increase the thickness of the natural oxide layer and protect the metal, as the layer has higher corrosion and abrasion resistance than aluminum.

What is Wire EDM?


Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning, or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks) Material is removed from the workpiece by a series of rapidly recurring current discharges between two electrodes, separated by a dielectric liquid and subject to an electric voltage.


How Does Wire EDM Work?


An electrically charged wire is used in the EDM process, which is the most significant characteristic of wire cutting. Then how does it work?


  1. First, put the workpiece to be processed on the workbench. You can cut it from the end of the workpiece, but at the beginning of wire cutting, the starting hole is usually connected to the material to avoid deformation due to the internal stress of the workpiece. When the worktable (or wire) moves in the XY direction (on the plane) according to the CNC data, machining is started.
  2. When the distance between the workpiece and the wire electrode in the insulating state in the working fluid is close to tens of microns, the insulation between them is damaged, and spark discharge occurs, resulting in the instantaneous flow of pulse current. In a high-density discharge state called an arc tower, a local high temperature of thousands of degrees is generated and the metal melts.
  3. In addition, the temperature of the working fluid around the arc column immediately rises and vaporizes, causing rapid volume expansion, resulting in an explosion between the workpiece and the electrode surface. This blows out metal debris.
  4. Then, when the pulse current is cut off and flows into the surrounding clean water, the molten metal cools and becomes fine debris. The debris is washed away, and the insulation between the electrodes is restored again, waiting for the supply of the next pulse voltage.
  5. In this way, the metal is melted and removed at each voltage pulse and repeated hundreds of thousands of times per second to cut the workpiece by wire cutting EDM.

Advantages of Wire Cut EDM Include:


  • Ability to machine complex shapes that would otherwise be difficult to produce with conventional cutting tools.
  • Machining of extremely hard material to very close tolerances.
  • Very small workpieces can be machined where conventional cutting tools may damage the part from excess cutting tool pressure.
  • There is no direct contact between tool and workpiece. Therefore, delicate sections and weak materials can be machined without perceivable distortion.
  • A good surface finish can be obtained; a very good surface may be obtained by redundant finishing paths.
  • Very fine holes can be attained.
  • Tapered holes may be produced.
  • Pipe or container internal contours and internal corners down to R .001".

Material removal mechanism for Wire Edm Machining


  1. EDM performance is generally evaluated on the basis of TWR, MRR, Ra, and hardness.
  2. In material removal rate (MRR) from all selected parameters, spark current is the most significant input factor affecting the machining of the workpiece. The performance is affected by discharge current, pulse on time, pulse off time, duty cycle, voltage for EDM.
  3. For tool wear rate (TWR) from all selected parameters, spark current is the most significant input factor affecting the machining of the workpiece followed by spark time and voltage.
  4. Innovative technology in the EDM is unceasingly progressing to make this procedure further appropriate for machining. In the field of manufacturing additional attention is on the optimization of the method by dropping the number of electrode.
