Flatness, thickness parameters, parallel, roughness values
In various sectors, the demand for precision sheet metal is high. For instance in the general construction of tanks and appliances. But with Van Geenen’s precision grinding, a full-fledged alternative is now available. It has virtually no restrictions in size, due to the large vacuum table. This table can easily and firmly attach magnetic and non-magnetic materials.
It can also process materials that are known to be hard to grind. Such as titanium. Since it is highly flammable, it cannot be ground on dry grinders. With this wet grinding process, Van Geenen offers the solution for easily applying a finish and grinding at the exact thickness, for instance for the Aviation industry, where every gram counts. Precision grinding at Van Geenen is an efficient way to grind sheets that are rolled and delivered at a standard thickness by the factories, to the exact thickness necessary with extreme accuracy.
The machining grinding process is conducted with a sanding belt. In contrast to regular sanding machines, this sanding head does not follow the uneven structure of the sheet, but is instead fixed. The sheet is placed on the vacuum table and is treated with the sanding head until it is completely “topped off” and is equally thick everywhere. It is accurate up to 0.02 mm.
