Choose a web for a tape saw for metal

The web for a ribbon saw is a key element that determines the quality of the cutting machine and the possibility of the machine. The material of this article will help the reader to decide on the choice of tape for metal and will tell you what to pay attention to when buying.

What is it?

The metal blade for the metal saw is called a flexible cutting blade in the form of a ring, which can have a teeth of different types. They play a key role in choosing this element of the band saw. The canvas are used for cutting in metalworking. At the same time, it is used both on domestic and industrial equipment.

What you need to know?

The linkeropile canvas is distinguished by such criteria as the material from which it is made, the shape of the teeth, the wiring option. The ribbon itself is made of high-carbon steel monolithic type or bimetallic alloy. Steel products, which are characterized by resistance to the gap to 80 MPa, are used during the cut of non-ferrous metal, steel and cast iron blanks. Such canvases are used on aggregates of the console and single-suitable type of professional and semi-professional destination.

Bimetallic ribbons are used on high-power two-sided equipment. Such products are distinguished by the complexity of the design, have a flexible ribbon of spring steel with high-speed steel teeth. The hardness of these canvases is approximately 950 HV. Their teeth are located in the nests and are fixed by electron-beam soldering. These options are suitable for cutting continuous blanks, copier with cast iron and steel solid alloys.

One of the tasks of the buyer is the right choice of wiring and shape of teeth. This will allow the use of carbide canvases of band saw equipment when working with stainless steel.

To speak more specifically, for the cut of high carbon steel, you need to take the canvas from the composite alloys of the M-51 brand. For medium and low carbon, bimetallic tapes M-42 are suitable. SP should be taken when it is planned for long-term work with heat-resistant steel. TST options are suitable for working with titanium and nickel blanks.

Criterias of choice

There is no universal product that can satisfy all customer requests. Therefore, when buying will have to pay attention to a number of moments. For example, the width must be selected based on the type of work. It varies in the range of 14-80 mm. The standard is considered to be models for 31-41 mm. So as not to get confused, you can refer to the instructions of the available machine. As a rule, it always indicates the main characteristics of the desired canvase. Following specific parameters, you can purchase the correct option, thanks to which the machine will work high performance.

Type of teeth

Cutting tape teeth have a special location. It is not direct, but the main ribbon rejected from the plane. The type of such location is called a wiring that is different. To date, it is divided into three types: straight, wave and alternation.

Alternate deviation of teeth in the right and left side allows you to provide a wider form of cut. At the same time exclude the jams of the tape in the processed workpiece. We are more often buying canvases, who have a wiring:

  • right, right, left;
  • to the right, left in turn;
  • wave with a change in the angle of tilt tooth.

The first type canvases are used in working with solid blanks, pipes and profiles. The second option is considered universal, however, as practice shows, it is better to show itself in working with soft metals. The third type of wiring is used in working with thin-walled pipes and small amounts of blanks.

Form

The shape of the teeth in tapes can also be varied. Developed standard solutions allow you to choose an option, taking into account the needs of the buyer.

  • Edge with normal teeth Located upwards relative to the canvas. This form does not touch the chamfer, use it when cutting parts from high carbon steel.
  • Hook has frontal tilt 10 degrees. Cutting with such teeth can be solid rods of different sections made of alloy steel. Also these web can be cut with thick-walled blanks.
  • RP version characterized by the slope of the cutting edge of 16 degrees. Cloths with such a form of teeth buy to work with colored alloys. You can also use such a ribbon to cut the hardwood alloy.
  • Master shape considered universal and most common. Its chamfer can be 10 and 15 degrees, there is also grinding of the longitudinal edge, which reduces the roughness of the treated edge.

Step

The canvas for tape metal for metal may vary and the number of teeth. Step selection directly affects the quality of the cut. At a constant step, the number of teeth can be from 2 to 32 per 1 inch. At the same time, the more their number, the less should the thickness of the workpiece should be. In analogue with a variable step, the number of teeth varies in the range from 2 to 14 per 1 inch. The choice of the right step of the tooth is selected taking into account the thickness of the walls of the pipes and profiles with which they will have to work further.

Speed ​​cut

Cutting mode will depend on different indicators. One of them is the material being processed. We will have to take into account the group of steel and alloy, as well as the size of the part itself and the pitch of the teeth. Here you will have to choose a specific trademark, since this factor also determines the quality and efficiency of the canvas.

Rotation speed of ribbons Nonodynakov, when buying, sellers will indicate it. It is important to determine and with the feed rate of the belt cloth, since ideally every tooth saws should cut the chip of a particular thickness. Each machine has its own set speed, and therefore to select the desired value will have to be based on this. Of course, you can go experimentally, to buy a tape and look at its effectiveness in chips. However, it is better to initially select the desired option, because the quality of work performed directly directly. In addition, it is important to understand that the capacity of the canvas and its resource is not infinite.

When buying, you need to rely on the recommendation of firms producing this category of goods. You can also use speed and performance tables. Despite the fact that they indicate the averaged values, and the real parameters may differ slightly, it is better than to go using the experimental selection method.

The speed of rotation of the tape and the feed is considered key criteria. Relying on them, pick up modifications of the canvases, the pitch of the teeth, wiring.

Operating tips

      So that the equipment works most efficiently, it should be stable. For this, it is aligned in the horizontal plane. The voltage and current of the power supply must be correlated with the operating voltage and the current current. Before use, it is important to check the direction of rotation of the tape saw. In addition, there is a visual inspection of equipment for damage. Sometimes you have to pull the tape, guided by the manufacturer’s instruction.

      The unit is launched and performing a cutting cycle without material. At this time, pay attention to the functionality of the machine, smoothness of the launch and operation of other nodes. For starting and stopping the machine has a special buttons. Sawing material only when it is clamped.
