- Belt grinding
Belt grinding is a machining method to process metals and other materials, with the aid of coated
The basic difference between belt grinders and
belt sanders is the material being machined. Sanding is the machining of wood, grindingis the common name for machining metals.
Belt grinding is a versatile process suitable for all kinds of different applications. There are three different applications of the belt grinding technology:
surface roughness, removal of micro burrs, cosmetic finishes, polishing
# Deburring: radiusing, burr removal, edge breaking
Stock removal: high stock removal, cleaning (e.g. of corrosion), eliminating mill or tool marks, dimensioning
Wide belt grinding is a familiar process in industry as well as home applications. There are several basic methods for belt grinding:
* Stroke belt
* Platen belt
* Wide belt
* Backstand (pressure)
* Portable (manual)
In general there are three basic elements of the belt-grinding machine: work rest support, grinding head and a regulating head. These components differ for all the methods but in general the workpiece is pressed between the grinding head and the rest support. The objective of the regulating head is to coordinate the belt pressure.
Wide belt grinding
One of the most common methods is wide belt grinding. Timesavers Int. BV is a manufacturer of these machines.
The belt grinding process is versatile by other adjustable components. The machines can be wet working or dry working. Furthermore a wide belt grinding machine can be constructed with single or multiple heads. The first head is used for coarse grinding and the next heads gradually makes a finer finish. Wide belt grinding is also used as a high stock removal method for special metals (e.g.
stainless steel, titanium, and nickelalloys).
There are several objectives possible for grinding with coated abrasives. Among them are the right application (e.g. finish or stock removal), time saving and efficiency of the abrasive tool.
To achieve the above objectives, it is essential to look in more detail to the variables, which affect them. These include the work material properties, the grit and abrasive type of the grinding belt, belt speed, belt sequences, contact wheel hardness and diameter, serration, type of lubricant (or dry) and grinding pressure. Changing these variables will affect the performances of the belt grinding process.
In the wide belt method, a contact wheel supports the abrasive belt. The selection of the contact wheel and abrasive to match the grinding parameters required for a specific operation is very critical. Stock removal generally requires a harder, serrated rubber contact wheel, and coarse grade ceramic abrasives. Finishing generally requires the use of a smooth faced contact wheel and fine grade abrasives.
