Non-magnetic workpiece surface finishing - uses ferromagnetic grinding powder in magnetic field with ferromagnetic rods between workpieces

摘要

The finish machining of surfaces on non-magnetic workpieces uses ferro-magnetic grinding powder in the magnetic field which is produced by opposite unlike poles of a magnetic system. The ferro-magnetic powder is arranged in the magnetic field and a so called 'cutting brush' of the powder is formed. Non-magnetic workpieces are then introduced into the field and are moved with respect to the 'cutting brush'. A ferro-magnetic body (6) is arranged between each pair of non-magnetic workpieces (3) and thus is moved with respect to the 'cutting brush' of ferro-magnetic powder (1) and ensures the re-making of the cutting brush. The ferro-magnetic body (6) has an aerodynamic profile.
