In order for metal structures to acquire the correct and beautiful shape, as well as the ideal parameters specified in the project, it is necessary to process all the elements. To date, there are several ways to solve this problem, but the most popular of them is milling. How accurately these works are performed will depend on a correctly selected cutter that acts as a cutting material. In order to choose the most suitable type of tool, you need to adhere to certain criteria, among them - the variety and amount of work; metal quality, more precisely, thickness and softness; quality finishes, which may be secondary or primary; the geometric shape of the base, which can be a flat plate. You can make grooves or holes with a milling cutter. Among other things, it is important to take into account the given dimensional accuracy. The price of milling cutters for metal can be equal to 300 rubles and higher.
If it is supposed to carry out mass work that involves the formation of several varieties of surfaces with different lines, you need to pay attention to the sets. The cost of a mill for metal in this case will be significantly lower, and the variety of configuration will allow for several types of work.
What to look for when choosing
If you need a milling cutter for a metal milling machine , then when buying, it is first of all important to consider which manufacturer made the goods. It is necessary to choose brands that have been tested by experience and time, which will allow to avoid low-quality sharpening, quick breakage or inaccuracy of the cutting parameters on slices. The following is a list of manufacturers recommended by professionals: Bosch, Hahnreiter, Optimum, Attack, Tool Service.
The second thing you should pay attention to when a milling cutter is purchased for a metal milling machine is the principle of the mechanism. When choosing a cutting tool, the quality of the machine is important. Thus, the hand mill can be an automatic or semi-automatic device. For this equipment you have to choose a suitable nozzle. Experts advise taking into account the conformity of the internal fastening. This parameter is as important as the quality of the work surface. The presence of veneer is also required, which is required for a snug fit of parts to the surface of the rotational mechanism.
Choice of a mill by diameter and quality of sharpening
When choosing a milling cutter for a metal milling machine, you need to pay attention also to the dimensions that affect the usability of the equipment and the cost. Each master must choose for himself the most suitable combination. The structure of the cutter can be prefabricated or monolithic. Among other things, the better the tool will be sharpened, the quality of the cut will be higher. Its implementation will have to spend much less time. Professionals do not recommend choosing cutters that have a unique sharpening. This can be both a virtue and a disadvantage. Such a mill will be difficult to recover after it becomes dull. Many consumers like the offer of a number of manufacturers, which is expressed in replaceable knives. They provide the longest use.
Selection of cutting material
If you need a milling cutter for a metal milling machine, it is important what material the cutting element will be made of. Most important is the quality of the tool material, which will not depend on the type of design of the cutter. The most common in this regard are carbide products that are designed to work on metal. This is due to the high temperature resistance.
Why choose carbide milling cutters
Among the advantages of such products, one cannot but note the external strength and rigidity of the tool, which is so necessary for carrying out the corresponding work. If you want to exclude fast heating during the manipulations, then you need to choose this kind of cutters, since they differ in an impressive temperature of incandescence. If you want to extend continuous processing, then you should use such elements that are equipped with an internal cooling rod. Carbide milling cutters are excellently suited for tough, hard-to-work alloys, among which are cast iron, titanium, stainless steel and alloy steel.
Milling cutters for metal, which comply with GOST during manufacture, as a rule, manifest themselves well in the process. However, if you have purchased a product that has some negative performance characteristics, then you should no longer prefer this or that manufacturer. In addition to the selection criteria that were mentioned above, it is necessary to take into account the moments that in some cases arise during processing. Here it is possible to note the impressive heating of the tool itself and the formed parts, namely the shrinkage of the material, curling of the chips, the appearance of growths during the formation of parts, the last of which concerns plastic soft metals. This includes vibration.
Specialist advice
The master must treat these conditions with special attention. These manifestations can affect not only the time of the manipulation and slow down the process. You may end up with low quality machined parts.
Application features
You are already familiar with the fact that the sharpening of a mill for metal should not be unique. However, you also need to know that there are different types of products that are designed for certain types of work. It is important to familiarize yourself with the recommendations for using the most popular cutters in accordance with the specifics of the manipulations. For decorative and rough processing of the bases, depending on the type of tool, you need to choose a more impressive diameter of the rod. The teeth should have a large size and a lower frequency of location. As for the end mill, it should have fewer feathers. Initial processing products should be used for rough finishing, with the help of them it will be possible to create outlines of geometric shapes. In this case, the master will get rid of the thick layer of the surface.
Cutters for fittings
To carry out such work, products of a suitable profile should be used. The easiest option is to create an angle with a certain degree. To do this, it is customary to use angle cutters. Multi-profile nozzles help create channels of complex shape.
Cutting off
Cutters for metal have a circle shape along the edge of which the teeth are located. Depending on the work, you can choose the type of product, taking into account the size and cleanliness of the cloves. A metal disc mill should also be selected in thickness.
Registration of grooves and ledges
For processing and creating complex and simple geometric shapes, cutters with triangular, trapezoidal and rectangular ledges are used. In this case, an end mill for metal can be used, as well as an end and disk one. Products with round plates will create volumetric shapes.
For external recesses of various shapes and types, a metal end mill should be used. As for the end ones, with their help the work can be performed on the outer surface, as well as to form deep internal grooves.
Hole making
To make holes of the required depth, which can be through, you need to use edge or end mills. Crown products for metal can also be attributed to this. The latter are capable of cutting metal along the edge of the hole. Because of this, they are in such high demand. Separately, it is worth highlighting the ball mill. Its use allows you to correct different shapes and give the texture of the surface.
Threading and teeth
A metal disc mill is perfect for solving such problems. Among other things, you can use worm gear. You can get a thread with one or more tools, each of which will be selected separately. For example, one cutter will be used for making holes, and the other for notching.
Conclusion
After you find out what the crown-shaped mill for metal is used for, as well as other varieties of such products, you can safely go to the store in order to purchase the right product that is suitable for your tool. A distinctive feature of the latter is the possibility of using various milling cutters in tandem with it, which will help to perform work for various purposes. Before making the final choice, you need to make sure that you have looked at all available materials, as well as options from the category of interest. Only in this way can you choose a crown mill for metal or any other consumable for milling machines.
