Description
Procedure: Electropolishing
and Mechanical polishing.
Definition:
Stainless steel pipe polishing process is actually the inside or
outside surface of the pipe polishing process, using polishing
equipment and the friction of pipes surface, to meet the roughness
requirement.
Type:
Stainless steel tube of polishing with internal surface polishing
and external polishing; Dry and Wet.
Grade:Polishing grade : the outer surface of #
**0 , # **0, brushed , Silk hair.
Difference between Wet bright and Dry
Bright:Grinding resistance : ( light ) resistance and abrasive
grinding machinery, the rigidity of the workpiece support system ,
but also with grinding in the grinding temperature, vibration , or
a relationship , but also affect the life of grinding tools ,
grinding the surface of the characters .
Grinding temperature: grinding thermal
deformation temperature would reduce dimensional accuracy , surface
grinding process also affected the metamorphic layer.
Application: Mechanical treatment; Mechanical working; Tool, CNG,
Automobileengine, Decoration.
Electropolishing features: Electro polishing
is the use of stainless steel in the electrolyte solution in the
selectivity of the anode to achieve the purpose of polishing and
cleaning the surface of a surface treatment .
Advantages:
(1) Greatly improved corrosion resistance. Since electropolishing
selective dissolution of the elements , making a solid surface of
chromium-rich layer of dense solid transparent membrane , and
formation of electric surface , eliminating and reducing micro-
cell corrosion .
 (2) Micro- electrolytic polishead surface is more smooth
than the mechanical polishing , reflecting a higher rate . This
makes the device non-stick wall , not hanging material , easy to
clean surface about a reduction of approximately one wire , to GMP
and FDA regulatory requirements .
 (3)Electrolytic polishing from the workpiece size and shape
restrictions. Mechanical polishing on the appropriate
implementation of the workpiece can be polished , for example, thin
tube wall , elbow , bolts , nuts and containers inside and outside
the wall .
Â
Electropolishing superior than mechanical
polishing :
 A. a surface potential conditions;
 B. difficult to capture pollutants;
 C. surface can form a more solid salt corrosion resistance
of the transparent membrane;
 D. does not produce Beillby layer .

Electrochemical polishing
characteristics:
Electrochemical polishing is the use of electrochemical anodic
dissolution of metal grinding polishing principle . The
electrochemical pre- polishing and fine polishing machine together
organically , playing two types of electrochemical polishing
expertise and institutions . It is not material hardness and
toughness of restrictions , complex shapes can be polished
workpiece . The method and electrolytic grinding similar
.
