3 top tips on belt speed for 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.

Choose the right belt speed for top results.

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.

At a lower speed, you can sand accurately.

Low belt speed is required f.e. for watchmakers, precision grinding, detailed work, fine instruments, jewellery, non ferrous metals. High belt speed or high motor power f.e. for fast productions and long-term intensive coarse grinding.

Standard setup specifications of a standard belt grinder
There are many types of belt sander. Here is a guideline that you can take as a basis, with which you can do many operations on metals, wood and plastics. Think of knife making, metal working, watch making, instrument making, renovation, restoration, blacksmithing, knife sharpening, interior design, furniture making, door fitting, machine building, musical instrument making and restoration etc etc.
Belt speed: 15m/s
Belt speed with a variable speed control: 8 – 15 m/s
Drive wheel: 10cm
Motor: 230V or 400V / 2800 rpm
Motor: 1.1kW or 1.5kW

Here are three super tips for setting the right sanding belt speed for your belt sander. First, there is the speed of the motor. Then there is the diameter of the drive wheel. And thirdly, there is the rotational speed control. With a combination of these three factors, you can set everything to your liking. Exactly as you want it. For a top result from your work.

With a combination of factors, you can have a top-notch result.

Tip 1 Low belt speed
For a low belt speed we can take a 1400rpm motor. With the standard drive wheel of 10cm it gives a belt speed of 7.3 m/s. With a variable speed control the speed range is 3.7 to 7.3 m/s.
Speed range with a variable speed control and different drive wheels are:
Drive wheel 8 cm – speed range: 3,0 – 5,9 m/s
Drive wheel 10 cm – speed range: 3,7 – 7,3 m/s
Drive wheel 12 cm – speed range: 4,5 – 8,8 m/s
Drive wheel 15 cm – speed range: 5,6 – 11,0 m/s
We can make every size drive wheel.
The 1400rpm motor can be 1.1kW or 1.5kW / 230V or 400V.

Low belt speed is required f.e. for watchmakers, precision grinding, detailed work, fine instruments, jewellery, non ferrous metals.

Tip 2 High belt speed
The standard 2800rpm motor and the standard drive wheel of 10cm it gives a belt speed of 14.5 m/s. With a variable speed control the speed range is 7.5 to 14.5m/s.
Speed range with a variable speed control and different drive wheels are:
Drive wheel 8 cm – speed range: 6,0 – 11.6 m/s
Drive wheel 10 cm – speed range: 7.5 – 14.5 m/s
Drive wheel 12 cm – speed range: 9.0 – 17.5 m/s
Drive wheel 15 cm – speed range: 11.0 – 21.8 m/s
Drive wheel 20 cm – speed range: 15.0 – 29.1 m/s
We can make every size drive wheel.
The 2800rpm motor can be 1.1kW or 1.5kW / 230V or 400V.

High belt speed or high motor power f.e. for fast productions and long-term intensive coarse grinding.

Tip 3 Motor power & VFD
For more motor power, we can take a 2.2kW motor, where normally 1.5kW or 1.12kW is sufficient. A 400V motor can run on the 230V mains with the variable speed drive. With 400V you have more power than a 230V motor.

A 400V motor can run on the 230V mains with the variable speed drive.
