Nail milling machine – how to care for it so that it will serve for many years

Nail milling machine – how to care for it so that it will serve for many years: A nail milling machine is a tool that we will meet in virtually every beauty salon, it also appears more and more often in our homes. Depending on its purpose, it can be used for manicure or pedicure. Significantly shortens the time of work and nail processing. Thanks to it, instead of arduous filing of the cured mass on the nail with a file, we can remove it in a few minutes. With skilful use, the risk of damaging the nail or cuticles is practically zero. However, like any device, the milling machine also requires maintenance and care to maintain its proper condition. Below you will learn how to care for the milling machine so that it will serve for many years.

Manufacturer’s recommendations

Each device we buy comes with an instruction manual. The manufacturer specifies how to care for the equipment, how to maintain it, and how to treat the device. Reading the manual is important, not only for use, but also for the warranty. Improper use or misuse may void the warranty, which may result in the loss of your milling machine without the possibility of a refund or repair of the equipment.

It is also important that you do not repair your device yourself during the warranty period. First, it may void the warranty as above, as well as damage the hardware. If we are not sure how to repair our milling machine, it is better to take it to an authorized service center. This will not only extend the life of the device, but can also prevent its further failure.

We should also remember that not all milling machines can be used for both pedicures and manicures. Milling machines for pedicures have more power, and milling machines for manicures have less power. This fact alone should tell us that their destiny does not come out of nowhere. Manicure models cannot be used to work on the feet, as they will quickly get damaged.

Choosing the right cutters

When buying a milling machine, you should consider what cutters you will need for the job.

The first and most important thing is to realize what we need cutters for, and then buy according to their application. Many online stores, such as the Kerpro store, have cutter markings. Each copy has a description and its purpose. Cutters can be filtered by gradation, as well as their application.

The second step, of course, is the purchase. Always choose good quality cutters. It is not worth investing in cheap substitutes, because it may turn out that not only will they not fulfill their role, but they can also damage our milling machine, because poorer quality cutters may start to warp.

It is necessary to check what size of the milling cutter’s shank will be suitable for our milling machine. Their dimensions are given in millimeters. We should only use cutters whose shank size corresponds to our milling machine. Too wide or too loose shank will cause quicker wear of the chuck and even its damage. Most often, the diameter of the mandrel is 2.35 mm. We absolutely cannot make alterations ourselves! The milling machine achieves very high revolutions, and the use of self-made milling cutters poses a risk of damaging not only the equipment, but also the processed surface.

Also, when we notice that the cutter we want to use is damaged, we cannot use it under any circumstances. A bent mandrel or a damaged milling cutter head cause its unbalance, which may damage the milling machine holder.

Cutters should also be systematically cleaned and disinfected. Always remember to keep the cutters dry. Moisture favors the oxidation of the metal, which will cause corrosion, i.e. the appearance of rust. Such a cutter can also damage our milling machine. There is a possibility of its “slipping” and falling out of the holder during operation.

Regular cleaning

The milling machine requires regular cleaning. In addition to cleaning the outside, we also need to take care of the inside.

The handle of the milling machine, also known as the pen, is particularly vulnerable. During operation, dust gets into it, which can cause overheating, as well as additional vibrations. Therefore, remember to clean it regularly. This will not only maintain hygiene and safety, but also extend the life of our milling machine.

Many milling machines are also equipped with an extractor. Remember to empty it regularly, because a clogged bag can also cause overheating of the equipment. A rupture of the bag can also cause dust to enter the engine and cause permanent damage.

Milling machines are also equipped with filters, which should also be replaced regularly to ensure air access


As we already know, each cutter has a marked scale of revolutions that should be set during their use. Setting the speed too low or too high will not only damage the cutter itself, it may also damage the router chuck. Turning on the milling machine and setting its rotation should take place before proceeding with surface preparation.


Many beginners press the cutter firmly on the surface they are working on. Contrary to popular belief, greater pressure does not mean faster working time. In this way, we can damage the surface of the nail, as well as damage the milling machine itself. When applying high pressure, there is a risk of damaging the router by breaking the head, bending it and damaging the handle.

Increasing the pressure can also cause more heat to be released. This will not only damage the treated surface, but may also cause the device to overheat.

After work

When we finish work with a milling machine, it is not enough to pack it in a box and put it away. There are a few rules that we must always remember:

          • cleaning the milling machine handle with a brush – helps to prevent dust build-up, and thus the risk of motor overheating;
          • disinfection of the device (even when used by one person);
          • setting the revolutions to “0” or “min”;
          • setting the switch to the “off” value.

The above steps will protect our milling machine from overheating. There is a risk that the motor will continue to work, as a result of which our milling machine will overheat and its motor will burn out.

The storage of the milling machine is also important. Do not excessively bend the wires and set it upside down. Also remember to keep the tool out of the reach of children. We must choose a place where they will not have access. It is also important to choose a place from which there will be no possibility of the milling machine falling to the ground. The parts of the milling machine are very delicate and can be damaged if dropped.


Tools such as a milling machine can significantly speed up and make our work more pleasant. However, when used by people who do not have the appropriate knowledge and skills, they can cause a lot of damage.

Many cosmetic plants offer basic and more advanced training in the use of milling machines. So if we are not sure how to use the milling machine, we should attend such training, thanks to which we will ensure the safety of ourselves, our clients, as well as the device itself. During such training, a professional will show us how to take care of the milling machine, what rotations to choose for the right cutters, how to choose cutters, what pressure to use and how to properly operate our device.

This knowledge can be invaluable to us, because thanks to it we can properly use and care for our milling machine, thanks to which it will serve us for a long time.
