Metal grinding is a process used to smooth and finish off metal parts. It’s most often used for finishing edges, deburring, smoothening welding joints, creating a sharp edge and for a range of custom edge finishes.

Metal grinding is used extensively in metal fabrication, and at its most simple is a manual operation in job shops. Large custom parts fabricators will typically automate the process through the use of finishing machines. Metal grinding is used to produce a variety of finishes and is an essential part of many manufacturing processes.

How do you grind a metal surface?

Manual metal grinding can be performed simply by using a file, but in most metal fabrications, this will be performed with a grinding machine. Metal grinding can be carried out with a mechanical handheld grinder, or with a stationary grinding machine.


A portable handheld grinding machine may be used in hard-to-reach areas when grinding larger metal parts that will not fit on a machine grinder.


What is the best tool for metal grinding?


There is a range of different types of machines used for metal grinding each of which is best suited for different jobs. These include:

  • Belt grinder: This uses a belt with an abrasive coating to grind metal for surface finishes.

  • Bench grinder: A benchtop grinder drives abrasive wheels to hand grind tools and other types of rough grinding.

  • Cylinder grinder: A cylindrical grinder is used to shape the outer surfaces of objects.

  • Surface grinder: This is an abrasive wheel that’s used to finish the surface of flat surfaces.

  • Bit grinder: These are used to sharpen tool bits and milling cutters.

  • Jig grinders: These are typically used for complex shapes, where high levels of accuracy and finish are required.


How do you safely grind metal?


Whichever method of metal grinding is being used, close attention needs to be paid to the appropriate safety protocols. Protective equipment needs to be worn. This will usually include safety glasses or goggles and a face shield to protect against flying particles. Gloves, aprons, metatarsal safety boots, hearing protection and respiratory protection should also be used.

How do you grind metal without a grinder?


If you have a small single metal object that you would like to make small adjustments to, then the simplest way to complete this is by using a metal file. For larger and more complex pieces, you may well require some form of grinder.
