This is usually the most labour-intensive process and typically requires a heavy duty grinding belt
. Many companies choose to invest in automatic or semi-automatic equipment for this task, with robots very much at the fore to deliver faster results.
2) In pressure-assist operations, in which the part is forced against the grinding belt
by pneumatic or hydraulic pressure, one way to increase productivity of a single station is to use a wider belt and a fixture that grinds two gates simultaneously.
Adding hydraulic power to push the casting into the abrasive can greatly increase the cutting capacity of the grinding belt
or wheel, removing large or thick gate and riser connections quickly.
The products and services offered to steel mill, forging, foundry, machine shop and OEM segments are mainlyl copper moulds, steel forgings, ingots and billets, master alloy ingots and billets, certified scrap, alloy tube and bar, grinding belts
and abrasive products, machining and fabricating.

The problem is, that robots move with an accuracy of +/0.1 mm, the tools, however, for example the grinding belts
or polishing mops do not have an exactly defined, constant effective operating point like e.g.
