POLIGRAT CHEMICAL DEBURRING
Why Chemical Deburring?
Chemical deburring will effectively remove all fine burrs over the
entire wetted surfaces, (such as holes, cross bores and recessed
cavities) including those areas where normal access is impossible. An
overall reduction of the general surface micro–roughness is also
achieved.
The Principle of Chemical Deburring
The immersion of a component in a specialised chemical solution, will
result in the controlled chemical erosion of the exposed surfaces.
The treatment involves immersing components into the chemical solution
either singly or on jigs. Large vessels, can be treated by using a
spray on technique. Processing of tubes or extended bores of
components can be achieved by pumping the solution through the areas
being deburred.
The amount of metal removed will be controlled by the immersion time.
The rate of metal removal will not vary greatly within the limits
governed by the chemical concentration of the deburring solution.
The actual rate of removal is approximately 1 – 3 microns / minute
dependent upon the material being processed.
What Materials can be Chemically Deburred?
Poligrat have chemical solutions and processes which are designed to
effectively deburr most of the common engineering materials. such as:
Austenitic & Ferritic Stainless SteelsMild Steel, Tool Steel & Speciality SteelsCopper & Copper AlloysAluminium & Aluminium AlloysNickel & Nickel based Alloys (Monel, Hastelloy, Inconel)Magnetic AlloysChrome Cobalt AlloysZirconium & Zirconium AlloysTitanium
Almost any size and shape of component can be treated
The Advantages of Chemical Deburring.
All wetted surfaces are deburred and smoothed, including those areas where normal access is impossible.Surface fissures are removed giving improved service life and component durability.Friction and therefore wear, is significantly reduced.Dimensional accuracy within fine limits can be maintained.Significant improvement in homogeneity and adhesion of subsequent plating deposits or CVD and PVD coatings.Operate without any mechanical distortion, allowing even the most sensitive components to be processed without risk of damage.The quality and strength of welded and soldered joints is improved.The fusing action with glass is improved.A totally clean metallic surface is generated
The Application of Chemical Deburring
POLIGRAT processes for chemical polishing and deburring are reliable
and economical in use. They have been successfully employed in many
areas of industry including for example:
machined components and pressingshydraulic and pneumatic controlspistons, tubes and nozzlestextile machine components and needlesgear wheels, pinions and ball bearing cagesstator platesspring and control switch elementsapparatus, containers and fittingswire and strip.
