EXTRUDE Hone has released a electrolytic deburring and polishing machine which performs four key functions in one finishing process, without subjecting work pieces to mechanical or thermal stresses.
The CoolPulse200 deburrs, polishes, stress relieves and cleans within one step. It is suitable for delicate small to medium-sized stainless steel or aluminium work pieces.
According to the company, potential applications lie in medical components, sophisticated aerospace parts, semi-conductors, and the automobile industry.
During the process, the work piece is immersed in a chilled, non-fuming, odourless, near-neutral electrolyte solution as a low voltage is applied.
The manufacturer claims the solution is safe for handling and environmentally friendly. The solution has high electrical resistance, said to allow high selectivity and high discrimination to remove burrs and peaks on the surface of the work piece.
Changes in the electrical settings on the machine will allow the process to be applied to different types of metals. A side-effect of the process is a mirror-like finish on the metal.
