Knovelhead - The Production
|
|
|
For the production of the Knovelhead rocker boxes first we need a sand form for the front box and one for the rear box.
|
|
The most essential cavities are already
provided by cores worked correspondingly in the sand form. However, the cores are even more important for the quality of the material composition.
|
|
|
|
After the casting the brutes must cool down befor further processing. Here you see a front and a back one with the typical casting trumpets and the frames.
|
|
The casting trumpets and the frame were removed with a band-saw here.
|
|
|
|
The rough burrs which inevitably arise at the cast as well were also removed here.
|
|
You see the inter-condition of a front rocker box after the first processing steps which follows the casting here well.
Left are still thin burrs and two extentions which we need for the later CNC processing.
|
|
|
|
The thin burrs and sharp edges were removed by an expert at the ribbon grinding machine here.
|
|
|
The further processing follows on a CNC-milling center here soon, too
