Abstract

By, according to the invention, designing a surface treatment tool with a grinding head (16, 17) with cylindrical rollers (18), so that the tool (16, 17, 18) is balanced by weight because the tool's centre of gravity is close to the tool's surface treatment area, the tool (18) will automatically adjust according to the surface (25) of the treated workpiece, regardless of the level of the surface. Hereby is achieved a previously unknown simple way to surface treat, be it flat and curved workpiece surfaces alike. Furthermore, the tool (16,17,18) is balanced by weight so that treatment pressure can be adjusted according to need.

Abstract

According to the invention, a method is used for surface treatment of obꂌ jects (7), wherein wire rollers (15) are caused to contact the object (7) to exert a blow or hammer impact, which wire rollers (15) partly rotate (8), partly revolve (12), partly move (14) transversely to the object (7) on the belt (11). This ensures an effective and completely uniform treatment (knocking-off, cleaning) of surface coatings, including oxide layers, by a non-abrasive or non-cutting treatment, but solely an impact stress. A rotating wire roller (15) may advantageously be used, which roller is composed of wire elements (1 , 2, 3) mounted on stays (4) so that they may bounce slightly rearwards (9) at impact, and otherwise remain in the same position by means of the centrifugal force and the engagement of the wire end with an adjacent stay (4).
