All about ring saws

In the usual consciousness of people drank – this is in any case something direct. Next Association logical – gasoline saw with chains and all similar equipment. But there is one more type that a wide audience knows little.

Features of wood processing tool

The annular saw on a tree with separate specialists is called the end milling cutter. And this second name is quite substantiated. Similarity applies to the appearance of the tool, and on the processing of material. Typical equipment, despite the considerable amount of chips, ensures the passage of the maximum clean holes. Standard canvas of the ring saw on the wood is made in the form of a cutting crown.

The number of teeth and their profiles are selected in accordance with how strong and wet tree will have to saw. IMPORTANT: Almost all manufacturers of crowns are supplied as part of the sets. Due to this, changing the work unit, it will be possible to process and dry-cooling sheets. Moreover, there are special crowns for metal work. Regardless of this, the sawing canvas is divided into a working and tail part.

To cut through the birch, oak, pine or spruce, requires a bimetallic head, manufactured from high-class tool steel.

For processing metal surfaces and products recommended carbide elements. Tail blocks are produced using structural (undergoing hardening) steels. So that they are firmly connected with cutting parts, a brass alloy of increased resistance is used. Often the opposite face of the shank is equipped with landing places for electrically engines.

With the help of a special spring, chips are removed from the inside of the round saw. The main properties of annular sawing devices are:

  • the height of the working parts of the crowns (determining the depth of the tool);
  • the outer cross section of the cutting segment of the crown;
  • Tissue profiles.

In most cases, the height of the working fraction of the crown is 4 cm. The hardness and saturation of wood fibers differ – therefore, the real bullet can reach 3.5-3.8 cm. We are talking about maximum indicators, more accurate information can be found only for each specific type of blanks. As for the outer diameters, typical sets contain crowns with a cross section of 3-15 cm. When selecting this indicator, you can not forget about the constraints imposed by the total power of motors and the number of revolutions issued by them.

If the annular saw has a diameter of over 110 mm, it is necessary to work at a minimum speed, or put a special stand.

All this significantly complicates the case and increases production costs. It should be noted that part of the circular saws is performed by a reversing scheme. For masters, this is a very useful acquisition (you can keep the drive and one, and the other hand). But it must be borne in mind that after a long work, the tool, instead of cutting a tree, will rush to skip the top layer.

How to use wood?

A characteristic feature of the apparatus is a strong heating during operation. Therefore, you have to do quite frequent breaks. Violation of such a rule threatens the outlet of the ring saw. The only way to bypass such a limitation is a special air cooling system. Practical characteristics directly depend on how the parts of the typeset saw are connected.

If the shank and the cutting block are joined by a flat attack – the tool is not designed for significant shifting effects. You can only apply it briefly. For each passage is allowed to remove a very small volume of material. The diameter of the installed nozzles is limited 3 cm. If you put a larger element, it is unlikely to work steadily.

A more efficient option – the attack and placement of the shank in the landing part of the crown. This technique allows you to make fixation stable. Because the saws are more – up to 12.7 cm. The total duration of work also grows. But there is still the most powerful kind of ring saw.

In addition to fixing in the landing block, the crown is practiced by the use of support boil. It put on top. This solution allows you to increase the caliber cutters to 150 mm and above. Part of the firms mastered even the release of tools with a cross section over 200 mm (up to 21 cm). With such dimensions, the inevitable thermal expansion of the material will not hurt the tool.

Tips for choosing

It is not always possible to compensate for a shifting effort due to the large value of the annular saw. In addition, even this solution, reducing the heat load, does not exclude the loss of accuracy. Special technical devices used in separate models help to cope with this problem. These include the use of centering pins that interfere with the crowns “get off the way”.

IMPORTANT: The pin should be at the height of two own diameters and more, otherwise its effectiveness will be in question.

Very good if an ejector spring is included in the delivery set. It simplifies the peak of the deaf holes in the stuffing fibers of wood. After all, it is impossible to exclude in advance that you have to handle a pear, ash or hrybro. When it is planned to pierce the deaf holes larger than 7-7.5 cm, saws very well with auxiliary threaded nozzles. Their attachment to the lower parts of the glasses is made at least three screws. Undesirable to use very large (larger 4.5 cm) nozzles, otherwise the inertia will grow too much, and the drill will not cope.

More modern and practical are those annular saws, where, instead of hexual holders, fastened SDS format cartridges are used+. To guarantee effective processing of even solid thick wood for a long time, you need to use a power drive not lower than 1000 W. It should be taken into account when selecting the tool itself, because it must be compatible with such drills. Crowns by 16.8 and 21 cm are used mainly in the industrial segment. Practically excluded the situation when such a device may be needed at home.

additional information

The teeth of the ring saw on the metal and the tree does not differ outwardly. The whole difference between them is connected only with the chemical composition of the material. It must be borne in mind that such saws are designed to process only thin sheet metal. Attempts to cut through thick products will not lead. You can process:

  • metallic siding;
  • metal tile;
  • profiled steel flooring;
  • Leaf galvanized steel.

    But even these materials can not be drilled in high revs. Otherwise, the ring saw very quickly will be broken irretrievably. But also a very low tempo invalid – few who will like for hours punch every metal sheet. Conclusion Simple: You need to choose the average modes of operation. The ring saws of the combined type (for plastic and wood) are usually equipped with non-remote teeth of solid alloys.

    With the help of such tools, you can also pierce the Faneur, and fiberglass, and PVC panels.

      When the holes are prepared in the wooden walls, most often they have to refine with the help of electric jigsaw. Because if there is aesthetic considerations in the first place, it is better, instead of a saw, immediately take a logs. Diamond ring saw helps break through only concrete and steel. If you try it on softer materials, cutting qualities will quickly lose.
