The ribbon machine is considered high-tech equipment, can work with the most different materials and drink curly and rectangular contours. The principle of work is based on the functioning of ribbon of durable flexible steel connected into the ring. Patented the machine was in England at the beginning of the XIX century. But after a hundred years, they learned how to correctly connect the cutting cloth, which ensured the jewelry accuracy of the cut.
Ribbon saw is a main tool that is used to work with the most different materials. Ribbon saw consists of a flexible slotted ribbon having a teeth on one side. Put tape on the pulleys that are attached to the engine.
Pruggiles can be made of the most different configuration, which makes it possible to apply a similar tool in a wide variety of areas: from the production of furniture to the manufacture of building materials. Tape varieties saw:
- Electrical execution principle of action.
This tool differs from simple hacksov in that it has a closed principle of operation. You can cut such devices to almost any material.
The aggregates working on friction and electric space exposure are somewhat different from classic tape saws.
When choosing a device, you should know how a similar unit functions. For example, a ribbon saw on metal is a crook of all kinds of blanks. The presence of rotary mechanisms makes it possible to make a cut by any corners. Criteria for selecting tape saws:
- engine power;
- how much aggregate weighs;
- What are the sizes of the pulley.
Differentiation of equipment is usually this:
- 355 mm pulley diameter – is considered a slight machine;
- Pulley diameter 435-535 mm – medium;
- If the diameter exceeds 535 mm, that machine is considered severe.
The first type of machine tools is equipped with a 1.9 kW engine if the unit is more massive, its power can reach 4.2 kW.
Special standards are necessary for the canvas. With cutting metal, bimetallic canvases are also used, they are made from materials of several species. Most often – this is:
- Plastic durable steel;
- Wire made of special high-strength steel.
Pares are very popular, which are based on carbon steel. Ribbon canvases vary also:
- with CONSTANT HARDNESS CONGRUITE DENSITY;
- with flexible base and durable teeth Flex Back – Hard EDGE;
- Hard Back Calem Clotts.
The first canvas that are identical to hardness, can operate on pulleys of minimum diameters; At the same time, the strength of them can reach 49 units (HRC scale).
Second-type saws that are made of plastic steel have a solid tooth and have a rather complicated structure. Only the top edge of the cutting tooth is tempered (hardness 64-66 on the HRC scale).
And finally, the third appearance is the most durable (hardness up to 68 on the HRC scale).
The hardness of the teeth provides the level of productivity tool, its resistance.
If there is a high ribbon ribbon canvas, it is possible to make split works on large feeds.
The principle of operation of the tape cutting machine is simple: there is a bed, on which the electric engine and wheels are fastened. A flexible tape with teeth is moving on them. Energy from the motor using pulley is transmitted to this dynamic unit, which is adjusted using the henching head leveling.
Equipment functions from the network in three phases and one phase, much depends on the type of model. The processed item is supplied at a certain speed, which can be adjusted. Test parameters are associated with the width of the working area (usually it has a 1/5 ratio).
There may be 4 pulley on the machine, the number of pulleys reduces the size of the machine and lengthens the working facility. The canvas itself can be stretched using hydraulics or manually. To check the tension tension level, use a strainometer.
The canvas can be universal and specialized type, they can be used for various types of steels. Much depends on the characteristics of the teeth, which vary in accordance with these criteria:
- hardness coefficient;
As an example, the fact that the metal sheets with large teeth are used for processing metal sheets. The use of teeth of different sizes is also practiced, which significantly reduces the vibration and increases the efficiency of the cut.
Tool performance and its durability directly depends on steel brands, which is used. Metal M44 is usually used (this designation indicates the strength of the edge on the Vickers scale – 950 units).
For the processing of durable steel such indicators, there is little, therefore, the hardness of the steel brand M72 is required (from the calculation on the Vickers scale there are 100 points). The average rigidity of the material begins with the M52 mark.
Configuration dictates sharpening angle, as well as the outlines of the cutting element profile.
The teeth must have reinforced backs, then it will be possible to handle Calen Steel, which is present on such elements:
When working with a viscous steel between the teeth, a large period is left.
The wiring of teeth in tape saws is also important. For example, if you have to process a large solid wood massif, you need to create a narrow and wide wiring, then you can avoid pinching the tool.
Types of belt aggregates depend on the density of the invoice with which they work:
- Saw on a stone;
- Aluminum saw (soft metals);
- Diamond saw for carbon metals;
- saw for stainless steel processing;
- Hand mini saw for wood.
When cutting dense materials, the canvas is amplified by teeth created from special alloys. It is necessary to do this – otherwise the tool can come to dissent. Also, ribbon saws are:
Joinery ribbon saws are mounted on the basis of which various elements are mounted. The ribbon saw can be constructed if you wish yourself, it does not make a special difficulty. Massive wooden block is taken for the bed to reduce the level of vibration. The plane of the desktop is trimmed with thick plywood sheets. Corners are attached to the sidewall. The carrier bar is pulled out from the beam. Pre-drawn the necessary drawing, where all the necessary calculations are carried out.
It is important that the device size corresponds to the necessary needs, then work on the unit will be comfortable. Be sure to take into account the location and parameters:
- pulleys (lower and drive);
- placement of the engine itself;
- Where will the chips come.
Most often, the bed is made in the form of a massive four-trigger block, the sides of which are closed. The sidewall is formed in such a way that the spent chips accumulate in them, which is then comfortable to collect.
The tabletop is usually mounted on the frame, sometimes height is not enough, so this kind of construction can be to help.
The rod is made from the profile of 8×8 cm, the supports are attached in it on which the wheels are attached. Supports must be created from durable material that is able to withstand significant loads (wood, metal). Between wheels the distance should be such a massive log in easily.
The thickness of the pulleys can be any: the string will be stronger, the better the result will be. There are generally accepted standards for the working path ratio to pulley thickness: 1/100. Example: if a ribbon is 5 mm wide, then the wheel should be 500 mm. The edge of the pulleys is processed and is made by shown, which allows you to restore the center automatically. On the pulley itself it is necessary to cut through the groove so that the belt is attached there. Often it is attached to the pulley attaching cycling chambers, which does not allow the tape to scalin.
The upper pulley is attached to the block, which moves in the horizontal plane. Required for this unit whose role with success can play an ordinary timber that is attached to the lever.
Lower pulley is made of two wheels that are attached to the axis. One wheel performs a leading function, the second – the slave. When setting up the unit, it is important that the wheel does not have a play – this will avoid the appearance of “eight”.
After completing the assembly of the unit, tests are carried out: it is important that all the nodes work simply, there was no excess vibration, which adversely acts on the material and fastening.
It is also important to correctly put guides on a bar along the saw end: the saw should work exactly and the tape should not be saved or deformed.
Thus are often done: three bearings are fixed on a bar, two of which are given the direction along the edges, and the third – supports the ribbon. Often, in addition to bearings, wooden locksters are mounted.
Ribbon soldering is an important stage on which success depends on. Usually it happens in the equipped workshop. Guides most often make dynamic to be able to adjust the elements. Be sure to make a protective apron that closes the pulley. In the case of his scaling, the employee will not be injured.
The engine is also closed by apron – this will prolong its service life, it will be less mechanical particles in it

The cutting unit can easily be improved. Some additional accessories are significantly helping in the labor process.
- Good parallel and longitudinal focus allows you to make high-quality straight cuts. When processing non-strokes, the stop may be located close to the machine, sometimes it is even placed under the guide block. Some models have additional regulators that change the parameters of the stops.
- For a ribbon saw, you must put the guides correctly, then the tape will not be significantly deformed.
- Teeth wiring is done manually or for these purposes is used. Properly adjusted teeth affect the service life of the instrument, as well as the level of noise and vibration during operation.
- The strainometer is a device for measuring tape voltage, it is difficult to do without this device.
Before choosing the desired tool, Basic criteria should be known for which ribbon saws differ:
- Dimensions of propil;
- which canvas is involved;
- power usage;
- engine power;
- Compact parameters;
- the ability to customize;
- View of the feed of the material.
The equipment may be different, according to this and vary prices for it.
The tape itself can also change the speed of movement from 12 to 98 meters second.
Also units differ in tension tension parameters. The tape has power from 2100 W and can reach 3000 W and even more.
When choosing the equipment, you should not forget about the importance of the cutting tape on which the main load lies. Usually prefer products of a wide view, since the thin canvas quickly deforms and fails. If you have to process the workpiece where there is a thin metal, then you have to use a narrow tape.
Visually is easy to determine when purchasing: if the tape has a large teeth, it means that it saws on a greater depth. There is another indicator – this is a divorce of teeth, it directly affects the efficiency of the saw. For small works, there is enough profile in the form of a wave. The most efficient option is the location of the teeth in pairs.
Subtleties of operation
During cutting, the saw inevitably loses its TTX, the teeth are stupid. Periodically, it is necessary to make the right sharpening, divorce and configuration. To properly configure the tool, you need to follow these phases:
- preliminary sharpening;
- Finish sharpex.
To restore the technical characteristics of the cutting tool use, as a rule, cutting machines. First of all, it is necessary to eliminate defects in the tooth sinus, as well as to reanimate it with symmetry in relation to other elements.
During the wiring, the angle of inclination of the front and rear corners changes. The finish sharpening “brings the gloss”, lines all the elements. To properly make such a job require practical skills: so that the teeth again become the same thickness, it is often necessary to suck the saw edge into a rather large depth.
It is also recommended to carefully get acquainted with the instruction that is attached to each unit of sold goods.
It is also useful to replacing the drive belts of the wedge. The old pulley “remembers” the trajectory of movement, over time it becomes too hard. Leads such a phenomenon to excessive vibration. It is recommended to change such a belt to segment, which is more plastic.
Periodically adjust the balance of saw pulleys. To do this, first need to cut the old belt and see how the pulleys work in free mode.
Both pulleys are placed on the bed, the operation is repeated several times. If the labels have a good scatter, the pulleys are adjusted well. If the labels are grouped at one point, then it is necessary to align the pulley.
If you want to cut the overall boards, then you need a wide ribbon, which teeth have a special sharpening angle. Variable teeth pitch is also practiced quite often.
Double bearings are also very important: They do not allow the canvas to twist, reduce the vibration and friction coefficient. Also, double bearings significantly reduce the temperature of heating the working part of the instrument, which significantly extends its service life.
Ceramic crackers are also important – these inexpensive devices will allow to reduce the friction of the tape during operation, reduce the temperature. Ceramic crucks are practically not stepping, the manufacturer gives them a guarantee of 50 years.
It is also important for the availability of high-quality springs, replace them easily. Put the springs better more massive – they are cheap, but provide ribbon good tension.
Flippers-regulators are also important in the work of the ribbon saw. It is best to put a cast small flywheel (145 mm) with a convenient swivel lever. Such an important “trifle” allows you to easily regulate the tension of the canvas.
When working, it is important that good lighting is present. You can additionally acquire LED lamps that will allow to illuminate the working area. These devices consume little energy, the battery can be placed at the bottom of the machine.
By purchasing the unit, it is necessary to think not only about the TTX mechanism, warranty conditions are also important, the presence in the boring market and their cost.
Before buying, it is advisable to read reviews on social networks. In recent years, innovative BILORK belt saws appeared on the market – they are made of heavy-duty steel with different composite additives, such a material withstands a record amount of sharpening.
