Type
The general design features and purpose of the router depend on the type.
—
Vertical. The classic, most common type of milling cutter. As a rule, vertical devices consist of the motor itself and a specially designed sole that provides support during operation. The sole is often made adjustable in height, which allows you to change the distance at which the cutter protrudes and, accordingly, the depth of processing. However, this change can be accomplished in another way.
-
Edge. In accordance with the name, this type of router is intended mainly for edge processing and chamfering. Such units are lighter and more compact than vertical ones, which, in particular, facilitates work in cramped conditions. On the other hand, they are less productive and have fewer customization options (in particular, they are very rarely equipped with adjustment of the processing depth).
-
Lamellar. Specialized milling cutters designed for cutting grooves for lamellas - fasteners in the form of thin plates. The design of such a tool is such that each groove is cut literally in one movement - this significantly speeds up and simplifies the work. Lamella milling cutters, as a rule, are not intended for other purposes.
—
Additive. Similar to the lamellar ones described above, filler milling cutters are used to cut out “
...seats” for fasteners. However, in this case, these places are intended for dowels - oblong products with a round or elliptical cross-section (also known as choppers or dowels) and are not grooves, but holes, usually quite deep.
- For removing nail polish. The purpose of this type of router is clear from the name: they are used for removing paint and varnish coatings; the principle of their operation is similar to angle grinders (“grinders”). When removing varnish, you often have to deal with fairly large areas to be processed, so a tool of this type, as a rule, allows the use of large cutters that provide a larger working width. In this case, the engine power may be low, because The load on the cutter in this case is small.
— Milling motor. This type can be described as milling cutters with minimal equipment - consisting of a motor in a body, a spindle and a collet and devoid of a base, guide rails and other similar devices. As a rule, such tools have an oblong body and a fairly small size and weight, which gives quite a wide range of possibilities for their use - from working as an impromptu hand engraver to installing it on an automated machine. However, in most cases, motors for milling cutters will still require additional accessories.
— For cutting tiles. Another type of milling cutter, the purpose of which is described by its name. Such devices themselves have an oblong body and operate similarly to drills; however, the matter is not limited to round holes along the diameter of the cutter - a cutter can also be used to cut a line in the material, for example, to create a hole for an exhaust fan, or to cut a fragment of a non-standard shape. Such features are indispensable when working with tiles.
- Disk. Milling cutters using a disc-shaped cutting attachment. Their main purpose is to cut grooves. In design and principle of operation, milling cutters of this type are similar to circular saw, however, these tools cannot be equated. Unlike saw, disc routers do not cut through the entire thickness of the material - they only create a groove of a certain depth, usually a V-shaped profile, on the surface. Additionally, they use cutters instead of saw blades. One of the most popular uses for this tool is cutting fold lines on aluminum sheets.Power
The total power of the router, more precisely, the engine installed in it. The
higher this indicator, the more productive the device is, the better it copes with complex work, the more force on the cutter (torque) it provides during operation, and the greater the spindle speed can be (although a powerful tool is not necessarily high-speed). On the other hand, high power significantly affects the dimensions, weight and price of the tool, plus power consumption and network load increase accordingly. In addition, high torque in some cases (for example, with delicate processing) is frankly undesirable. Therefore, a tool should be chosen according to this parameter, taking into account the real needs and the specifics of the planned work.
There are three main categories of milling cutters in terms of power: light (up to 700 W), designed mainly for simple household work; medium (up to 1500 W), able to cope not only with domestic, but also with most professional tasks; and heavy (1500 W or more), used in cases where high power is critical. However, this gradation is true only for routers (see "Type"), other varieties have their own specifics: for example, lamellar models, in principle, do not need high power.
In box
Additional equipment included in the delivery of the router in addition to the device itself.
—
Fresa. Working nozzles — milling cutters — can be included in the delivery set of milling cutters, this eliminates the need to purchase such nozzles separately. On the other hand, before buying a tool with this feature, you should make sure that the complete cutters correspond to the features of the planned work — otherwise you may overpay for unnecessary nozzles. Usually, there are several cutters in the set.
—
Dust collector. A special container for collecting dust, sawdust and other debris generated during the operation of the router. Most often it is made in the form of a soft bag, and a special pipe is used to connect to the tool (a vacuum cleaner can also be connected through the same pipe). Note that the overwhelming majority of modern milling cutters are equipped with nozzles for dust collectors, but the bags in the kit are relatively rare. Usually, a dust bag can be purchased separately, but for some users it is preferable to immediately buy a tool with a bag.
—
Copy base. The copy base is the base (sole) of the router (see "Type"), specially designed to work with copy sleeves. The copy sleeve is a ring fixed on the tool body, into which the cutter is threaded. When working with such a sleeve, the operator rests the outer edge of the ring agai
...nst the template and moves the tool in such a way that the base is constantly pressed against the template. Thus, the distance between the cutter and the template remains unchanged, and the working nozzle repeats the shape of the template; this is indispensable for precise work, especially with lines of complex shape. Many routers allow you to install a copy sleeve on a regular sole, however, there are models in which you need to install a special copy base for this. Such a base has certain differences from the standard one, due to the specifics of the work — in particular, it usually does not have depth adjustment, because. the presence of an adjustment mechanism can adversely affect the accuracy of work.
— Protective limiter. The protective limiter is a small ring that covers the working nozzle. This ring, as the name suggests, provides additional protection for the operator from dust, chips and other debris generated during operation. In addition, it prevents foreign objects (primarily fingers) from getting under the cutter and increases the efficiency of collecting debris in a vacuum cleaner or dust collector (see above). And so that the operator can control the process of work at the same time, the protective limiter is usually made transparent.
— Guide rail. A device designed primarily to ensure that the router during operation can move parallel to the edge of the material being processed. The rail rests against this edge during operation, and the tool itself extends a certain distance from it on special guides. Thus, it is possible to cut recesses parallel to the edge of the workpiece. The distance from the rail to the cutter can be adjusted, some models even provide special scales on the rail itself.
— Case / bag. This category includes all devices designed for storing and transporting tools; at the same time, hard containers in the form of characteristic suitcases are usually called cases, while bags, on the contrary, are made of soft materials. Anyway, the case / bag simplifies storage and carrying: firstly, due to the fact that such devices themselves are more convenient for long-term carrying than a tool; secondly, due to the fact that the router, the power cord, and all additional accessories can be folded into one place, reducing the risk of losing any of it.
