The principle of the K - 2 Carbochem Processes
K - 2 Processes for chemical polishing and deburring use chemical
solutions, which operate at room temperature without electrical current.
Controlled chemical erosion polishes and deburrs the surface of the metal.
Unlike electrochemical processes there is no requirement for contacting the components electrically or employing cathodes in the tank. Treatment involves immersing components singly on jigs or loose in a basket or basket. Large objects, such as vessels, can be treated by using a spray on technique. Processing of tubes or extended bores of components is achieved by pumping the solution through the items being treated.
The amount of metal removed is controlled by the immersion time. The degree of metal removal will not vary greatly within the permitted variations in the concentration of the polishing solution.
The rate of removal is 0.5 - 5 urn/minute (20-200 micro inches/min.) dependent upon the hardness and composition of
the material being processed. Agitation of the solution, for instance by pumping, can greatly increase the rate of metal removal.
Treatment time depends upon the desired amount of metal removal and can vary between a few seconds and several
minutes.
The chemicals are supplied in the form of
salts and require dissolving in water to
produce a satisfactory bath
Chemical usage when operating is determined by means of a simple analysis
control. Maintenance of the bath is carried out by replenishing and replacing the
chemicals consumed. Correct control of the solutions ensures stable and consistent processing results over a lengthy period of time.
