Magnet machining refers to a series of processes that manipulate magnet material mainly through cutting, drilling, or grinding. By the end of the machining process, a magnet may have a completely different shape of design.
In most cases, magnetic material degrades during the cutting process. This is common especially when it is done near the edge.
There are different things you need while cutting a magnet like work gloves, a face mask, hacksaw among others.
Also, depending on the shape or type of magnet, you may adopt many techniques. This will depend on the type of machine you want to cut or the shape you wish to achieve.
For rubberized magnets, you can adopt this simple process:
- Use protective gear for magnet cutting. Protective gear helps since it protects you from shears and splinters which may result in injury.
- Mark for the cut – Mark the magnet especially where you intend to cut to enable you to know and give you an easy time when you will want to cut the magnet
- Cut the magnet – Cut the magnet according to the previous mark you had placed before.
There are also ceramic and magnetite magnets which are cut differently and the process includes the;
- Put on your protective gear and a mouth mask, protective goggles to protect your eyes from dust
- Use a vise that protects the magnet from slipping therefore prevent from losing its property
- Mark the magnet – It helps you to know where you will need to cut the magnet
- Cut the magnet with a hacksaw or any other cutting tool. The hacksaw will enable you to cut the magnet, especially after the previous mark of the magnet
- Use the diamond-plated wheel – you will mount the wheel on a rotating machine and then tighten it. Power the machine to cut your magnet.
- Cut the magnet with a chisel/ hammer – A chisel or hammer helps the magnet to break in two in case the cutting process fails as it is risky since it destroys magnetic properties
Although you can drill magnets, you must be careful to avoid the possibility of breaking the magnet. Remember, most magnets are brittle, therefore they can easily break.
Drilling holes through magnets requires special skills. There are different processes for drilling a magnet and they include;
- Put the magnet together and drill it bit by bits
- Put the magnet in a specific area with low-pressure
- Alternate the magnet
- Use coolant to flush the holes and this helps to prevent the magnets from overheating
You can use a bench grinder during the process. The steps when grinding magnets include:
- Use the surface grinder to make sure the magnet is in a position to use the grinder
- Make sure the magnet is secured by placing it in a position
- Go slow to make sure the magnet is not overheated
Precautions when Machining Magnet
Magnet machining is a delicate process that may affect magnets. For instance, machining magnets produces some heat that can cause demagnetization.
- Control heat due to the machining process. Overheating or temperature beyond the Curie point the magnet may be demagnetized.
- Always wear safety equipment like goggles face while cutting a magnet to protect your eyes from injuries
- Wear a work gloves while cutting a magnet to protect from shears
- While drilling you need to be careful and skillful this helps to avoid destroying the entire magnet
- When grinding always wear a face shield to protect your face from flying particles
- Always put safety boots on your legs while cutting the magnet to prevent injuries like cuts in our bodies.
