The processing of one steel plate by Wilson Benesch.
1 Selected high quality 8mm thick steel is cut by laser to a tolerance of 0.1mm.
2 This is then machined to provide all the mounting holes on Wilson Benesch CNC tooling.
3 The edge is then machined to a mirror finish.
4 The edges are then de burred by hand.
5 The ultimate surface finish is then produced by surface grinding.
Both surfaces of all plates used in every loudspeaker are prepared in this way.
Having been ground to the finest finish each plate is completely flat. Only when this has been achieved is the plate released to the powder coater. Here, an architectural specification powder coat is applied that will with stand the most hazardous climatic conditions.
At every stage quality inspection takes place.
The plate being machined in this image can be seen on Trinity. If you refer above to Trinity – “Looking up” you can see the plate when assembled.
Despite the fact that one side is impossible to see and the majority of the plate is obscured from view, this plate is treated in exactly the same way as the visible plate that may be used for the footplate for example.
One component – Many operations – Ultimate finish.
