The 10 best metalworking applications with a belt grinder

The belt grinder or grinder is ideal for all types of metalworking. The workpiece is given the right shape and finish quickly, efficiently and accurately. In addition to metal, it is also possible to sand steel, damask, hardened steel, non-ferrous metals, wood, plastics, mineral materials and stone. Here we deal with metal.

The belt grinder or grinder for all types of metalworking

A belt grinder is a machine with a sanding belt. It is also called a grinder. This sanding belt can run at a fixed speed. With a variable speed regulator you can make the belt run faster or slower. At a lower speed, the metal does not burn in as quickly and you can sand accurately.

Choose a belt grinder with many attachments.

It is important to pay attention to the amount of attachments when choosing a belt grinder. A belt grinder with a belt that only runs from top to bottom is limited. Choose a tilting belt grinder with a lot of attachments. By tilting the belt, it can run from left to right instead of just from top to bottom. A great advantage!

Forging, welding, restoration and design. That is where people work with the belt grinder.

The belt grinder can be found in the metalworking workshop at forging, welding and restoration. The belt grinder is also essential in design. Many design and innovation departments in industry and production have a belt grinder. The belt grinder is an enormously useful tool when designing products. Individuals use the belt grinder for grinding, sanding and polishing when doing jobs or making knives.

Let’s take a look at the steps the metalworker goes through on the belt grinder. There are 5 steps:

1 Coarse sanding. A lot of material is removed from a rough piece of metal with coarse sanding. The workpiece is given its shape. Sanding belts with a hard polyester backing are used. This way one can press the metal workpiece hard against the sanding belt. The grain size is between 36 and 80.

2 Intermediate machining. During the intermediate processing, the details are applied. Much less material is removed. The working pressure is lower. The back side of the sanding belt is not so hard. The grain size is between 80 and 120.

3 Finishing. The finishing gives the metal work its final appearance. In the finishing some metal is removed from the workpiece but not much. The sanding belts are thin and supple. The grain size is between 150 and 400.

4 Finish. After the finish the workpiece is ready. It is smooth, rough, reflective, matt or semi-matt. That is the choice of the metalworker. There are special sanding belts for each type of finish. The grain size is between 400 and 2000.

5 Polishing. Polishing is done on the belt grinder with a polishing belt and polishing grease.
