Speed of the parts rotation and pressure of the media are controllable, making this system an efficient finishing method. ... Paint preparation of ...
Since electropolishing is nonmechanical, it is important to note that the hardness of a metal part has no bearing on the burr removal. Additionally, since electropolishing is a nondistorting process, your stainless steel parts are never subjected to stress from polishing media, nor are they impinged or tumbled onto each other.
When installing flooring systems, both diamond grinding and shot blasting are methods used to prepare floors for epoxies and resurfacers. Let''s delve into these approaches and determine which is best for your floor installation.
