What's the power feed contacts?
what's the power feed contacts?had you even sound this word?maybe any peple didn't know about that ,let  me tell you more about it !

power feed contacts it can be conduction .it's samll ,but  it's so heavy ,and it's very usefull by wire cutting product .Yesterday ,i went to our factory to ask the master of our company Now ,i can learn more about the wire cut conductive .the outface look like a red dates .small ,but so heavy ,i can't believe the little components is too heavy .wire cut conductive is made by tungsten steel.the steel has a strong hardness ,density also so big .There are many kinds of shape round ,and flat act .
What's the Principle of power feed contacts?now i will get the Analysis,
one is hight cathode,Generally connected at the top, near the place where the cutting surface. Behind the two is broken wire connecting line identification, which is used to determine whether there is molybdenum wire used, according to the circuit, some manufacturers only one. Even Workbench is a high positive line.
Then how to Protection the wire cut conductive block?
Electrochemical oxidation of aluminum and aluminum ( conductive oxide ) :
In the electrolyte solution , having a conductive surface of the workpiece into an anode , under the action of the external electric current , in the production of an oxide film formed on the surface of the anodic oxidation process is known , the resulting anodic oxide film is a film or a membrane electrochemical conversion .
Electrochemical oxidation type oxide film and a natural oxide film is a stacked cell structure , each cell of a hexagonal prism , the tip of an arc -shaped pores possessed hexagonal star-shaped cut surface . Oxide film structure has two . near the substrate metal is a dense and thin , having a thickness of 0.01 ~ 0.05μm membrane pure AL2O3 , high hardness , this layer is a barrier layer ; outer surface of a porous oxide film , the crystal water with AL2O3 composition, hardness low.
Electrolyte by electrochemical oxidation of the main components can be divided into: sulfuric acid anodizing , oxalic acid anodizing, chromic acid anodizing ; at the oxide film can be categorized as : wear layer , corrosion layer , bonding layer , insulation layer , porcelain and decorative coating oxidation.
Also can be used for surface treatment of aluminum plating methods, improving the hardness of the copper foiling first and then hard chrome plating, decorative chrome plated decorative can , in addition can also be colored anodic oxidation treatment .
whit the analyze of above ,we can know it wire -cutting machine with the power feed contacts it can help someone product of the wire cut Operation!
