Machining Neodymium Magnets


After-market machining neodymium magnets.

Amazing Magnets does not generally recommend machining “live” fully charged magnets as they are brittle, sensitive to temperature, and generate magnetic powder which makes the operation tedious and messy.

 

Important Warnings:

Heat will demagnetize a magnet. Magnets have a maximum operating temperature and will permanently lose their magnetism when heated above that temperature. Usually, this is 176F/80C but depends on the exact material in question. Temperature specs can be found on the information page of the part. Low speed, soft pressure, and constant temperature checks should be used to avoid overheating or cracking the magnet during machining.

Magnet Powder. Neodymium magnets are composed of sintered metals which are essentially compressed powder that turns back into dust when ground, drilled or cut. Because the powder is magnetic, it sticks to the drill bit and magnet and can’t be easily removed. The best method is to move as much powder as you can to the edge of the magnet and pinch it with your thumb and index finger. Blue painter’s tape can be used to clean the remaining powder.

Rust / Oxidization
Most neodymium magnets are coated/plated with nickel or zinc to protect the substrate from oxidizing(rusting). Neodymium magnets are about 70% iron and
will rust quickly when exposed to air. Magnets become less magnetic and
more brittle as they rust.

We suggest re-coating the
exposed neodymium with some type of permanent coating. We have had
success with 2 part epoxy like JB weld. It will seep into the pores of
the sintered material and is not easily scraped off.


 

Drilling Holes
Glass cutting or Masonry drill bits (like the ones shown below) work best. The higher-end “diamond burr bits” also work, the cheap ones found in your generic Dremel kit don’t. It is important to have a bit that can break through the hard nickel coating of the magnets, as well as slowly and carefully remove the sintered magnet material.

California company, Amazing Magnets, relocates its Global Headquarters to Texas

Company to Break Ground in Round Rock, Texas on January 7, 2021

ROUND ROCK, TX – As a result of year-over-year growth, Amazing Magnets is relocating its business operations from Anaheim, California and building a state-of-the art global headquarters in Round Rock, Texas. The new headquarters will showcase an engineering design workspace, a media and learning center, and an innovative warehouse facility. After exploring several locations, the company was drawn to Round Rock for its entrepreneurial spirit, access to world-class talent, and beneficial cost of living. What sealed the deal for Amazing Magnets’ team is a core value it shares with the city of Round Rock–the importance of community.

Founder and Chief Executive Officer Tim Boettcher said, “Our roots are that of a family-owned business with a focus on giving back to the community combined with a passion for continuous learning guided by a unique global strategy and an incredibly talented team. After visiting Round Rock and witnessing its economic growth, diversification and meeting its people, we felt like we had found our home away from home. Everyone was so welcoming, kind and supportive.”

On January 7, 2021, the Amazing Magnets team, with invited guests including dignitaries from the Round Rock Chamber of Commerce, Council, County Commission, business community and media, will break ground on its 40,000 square-foot global headquarters. Leadership from the Altman Development Group will also be on hand to celebrate.

Amazing Magnets designs, manufactures, and distributes magnetic-related devices and products. “The Amazing Magnets team and organization exemplifies the type of people and businesses we want to attract and welcome to the Round Rock community. We are here to help and support them in their growth and hopefully become an integral part of their success,” said Jason Ball, the CEO of the Round Rock Chamber of Commerce.

 

ABOUT – Amazing Magnets is a global company that designs, manufactures and distributes magnetic-related devices and products. It also provides the crucial services associated with these mission-critical functions including engineering, testing, prototyping, contract administration, regulatory compliance and warehousing.

Gluing Neodymium Magnets



Gluing Neodymium Magnets


Magnet Preparation

1.) Sand the magnets with rough grit sandpaper (10-50 grit).
This gives the glue more surface area to grip. The rougher grit allows the glue to seep into the crevices created by the sandpaper.


a.) For best results sand in a crosshatch pattern.
b.) Try not to sand past the copper layer of the magnets plating. Most of our Neodymium magnets are nickel-copper-nickel plated. Sand just past the first nickel layer into the copper layer.
c.) If you are working with large quantities of magnets be sure to wipe or brush your work area periodically as nickel dust can build up and be difficult to clean off of the magnets. If you find a magnet covered in nickel dust you can use blue painter’s tape to remove the dust.

2.) Clean the magnet thoroughly with acetone or denatured alcohol.


a.) Wear gloves during and after cleaning the magnets. Even trace amounts of oil and grease from hands can cause the glue to fail.


Non-Magnet Surface Preparation 

1.) If gluing to metal, repeat the above steps from magnet preparation to the metal surface.

2.) If gluing to wood, wipe away any excess dust and ensure the area is dry.

3.) If gluing to plastic, repeat the steps from magnet preparation but ensure that the cleaning product you use will not melt or damage the plastic. Ie. Acetone will damage abs plastic.



Types of Glue for Magnet to Wood. 

1.) Jb Weld and other 2part epoxies are highly recommended when the application requires the glue to fight the full pulling strength of the magnet.


a.) Always consult the instructions and recommended usage of the glue you intend to use.
b.) Be aware that metal reinforced glue is attracted to the magnets. This can be a blessing for glue distribution and a curse for keeping the glue off one side of the magnet.
c.) Keep a rag handy for wiping away excess glue.

2.) Contact Cement or E6000 is recommended for applications where there is less force on the magnet. Ie. There is a gap between the magnet and the surface it is attaching to that will reduce the effective force on the magnet.



Types of Glue for Magnet to Metal. 

1.) Jb Weld and other 2part epoxies are highly recommended when the application requires the glue to fight the full pulling strength of the magnet.


a.) Always consult the instructions and recommended usage of the glue you intend to use.

b.) Be aware that metal reinforced glue is attracted to the magnets. This can be a blessing for glue distribution and a curse for keeping the glue off one side of the magnet.

c.) Keep a rag handy for wiping away excess glue.
2.) Superglue or E6000 will work for applications where the glue will not be fighting the full pull strength of the magnet.



Types of glue for Magnet to Plastic.

1.) Because there are so many different plastic materials and surface finishes, we recommend that you contact your glue providers such as 3M or Loctite for assistance in selecting the right glue for your specific plastic.
