The milling machine is a machine that helps you mold, cut and polish different materials, such as wood, iron, steel, among others.
This is possible through the use of cutters of different types and edges, which when placed in the machine perform rotary movements capable of cutting, so it is important to know their uses and functions.
The use of the milling machines depends on the milling cutters you use, these are interchangeable pieces that are embedded in the base of the machine and rotate at high speed to offer you some type of cut.
Likewise, you must take into account that they are normally made of high-speed steel or hard metal, while those of professional quality are made of construction steel, however, all types of burs have steel teeth or blades, which serve to obtain different results.
Usually, a router brings a generic kit of drills or some of the most basic ones, so it might be necessary to purchase a set of 12 pieces or more for greater versatility, in addition, this gives you more functionality in case you must perform various carpentry jobs. If you plan to purchase a router or already have one, it is worth reviewing some of the main jobs that are possible with it.
You can make moldings with a cutter for this task, which has a top-like design with curved sides to mold the piece, it is also known as a ballerina and allows you to advance perpendicularly or parallel to the surface.
Therefore, the more curved the design of this type of cutter, the more inclined the edge of the molding will have. This also depends on how deep you set the router before operating it, so it can work for heavier holes or finishes.
It is important to adjust the speed of the milling machine according to the type of wood or material that we are working, since this has a lot to do with the efficiency of the work and resistance of the machine. Once turned on, the movement must be done in the opposite direction to the rotation produced by the cutter. On the other hand, you may get more professional finishes if you use several types of burs to mold on the same piece, since this will have different levels and more details.
For this work it is advisable to use a lateral guide, which is usually included as an accessory in the router and you place it parallel to it, in this way you can make a straighter and more precise groove. The design of these cutters incorporates a type of disc that rotates to produce more or less superficial perforations in the material. When doing this work, it is important to slide the router slowly and steadily for a cleaner line.
If you want to make a deeper grooving, then the best thing is to pass the router twice, since this way you avoid accidentally cutting the surface, burning it or the machine working forced, in addition, you do not have to make a great physical effort. Likewise, it is appropriate that you clean the slot and workspace before running it again, this way you can be sure that you are getting an accurate job.
Slot cutters are not limited only to making straight movements, as they also allow making lines in other ways, through the use of dovetail, T-shaped cutters, among others. Likewise, the cutters indicated for grooves usually incorporate three cutting edges, made up of a front and two sides, to provide greater versatility.
In addition to making grooves, some burs allow you to cut the material, according to its depth. As in the previous case, it is appropriate that you use the lateral guide for a more precise and clean job.
Cutters typically feature a slim, straightforward, cylindrical design that is easy to identify and have varied edges to make a variety of straight-line cuts. In this sense, you can find them with very fine or thick teeth according to your needs.
On the other hand, to make a circular cut you need a metal pivot, which you must insert into the guide. The diameter of it depends on the size of the hole. Also, this type of cut can be produced by combining the rotation of the work surface and the milling machine, so it is very similar to the method used to draw with a compass. In this sense, if you move the router up or down, you can get an eccentric geometric cut, just like a crankshaft would.
A copier is a very practical accessory that you place in the lower central part of the router and allows you to cut and engrave different designs on the surface you are working on. In this sense, you can find all kinds of templates in woodworking stores, you can even make some with the use of wood sheets to make various drawings and shapes.
In addition, it is important to take into account that this type of cut is the most used to make toys and wooden objects with great detail and quality finishes. You can easily identify a copier by its round design and metal construction.
Recommendations for the proper use of the milling machine
Some of the best milling machines of 2021 ( In this link you will find several products to analyze ) are very versatile machines, which are generally essential in any workshop or home, whether you are a professional in the area or a hobbyist of carpentry and metallurgy.
In addition, they are usually affordable for most users. However, it is also one of the most dangerous tools, so it is important to take into account the advice of experts on the subject.
Before starting to use a router, it is advisable to think about some safety measures, such as glasses to protect yourself from the debris that may shoot, ear protectors, in case you have a model that produces a lot of noise, as well as a pair of gloves. .
Since if you use it continuously it could cause discomfort in the hands. These implements are key to avoiding accidents, but at the same time they allow a better performance in the projects you carry out.
