The range of mechanical surface finishing processes for stamped, turned or milled parts extends from deburring and surface smoothing, through precise edge rounding, to Super Polishing of high-performance components, for example in motorsport.
The result: components whose surfaces are processed in a targeted and reproducible manner so that their function precisely meets the specifications whilst also fulfilling high standards in terms of visual appearance.
- Deburring and grinding of stamped parts
- Deburring of aluminium profiles
- Deburring and polishing of impression trays, turned parts, milled parts and pot handles
- Pre-grinding and polishing of the lower-leg components of a knee implant
After stamping, parts usually need to be deburred, ground and, in many cases, pre-treated for subsequent Coating or chrome plating. They also need to be cleaned of stamping oil, i.e. subjected to degreasing.
On stamped parts, such as thin sheet metal, the edges usually need to be deburred or subjected to edge rounding. This step plays a key role in ensuring the components function correctly. At the same time, it makes assembly easier and ensures safe handling.
Mass finishing using circular vibratory finishing machines has become the established method for surface finishing complex milled parts with bores and through-holes. The MV series multi-vibratory finishing machines are the ideal choice for fine grinding or polishing workpieces with contours that are difficult to machine.
Thanks to the precisely controlled surface roughness, turned parts achieve better running characteristics and thus higher efficiency – for example, in pumps or turbines.
Circular vibratory finishing machines are used for cleaning turned and milled parts with coolant, grease or cutting oils. With gear wheels, the focus is often on smoothing the tooth flanks or rounding the root edges, which, amongst other things, significantly reduces friction coefficients. Circular vibrators or trough vibratory finishing machines are often used for this purpose.
