Types of adjustable machines
To carry out one-way or two-way wiring, separate types of wiring devices are produced.
Also, adjustable machines are designed to work in semi-automatic or step-by-step mode.
- Automatic adjusting machine for band saws - this machine eliminates the need to install each saw tooth under the device. Automatic routing machines allow you to obtain perfectly accurate routing, while significantly saving time. This will be evidenced by the smooth mark left by the sawmill on the surface of the product.
- Semi-automatic adjustable machine
- Double-sided adjustable machine
An adjusting machine for band saws is necessary for every woodworking industry.
buy an adjusting machine for band saws at a factory price in our online store.
The SAWS UNITED catalog contains adjustable machines for wood band saws. Such equipment ensures quick setting of saw teeth to guarantee long, trouble-free operation. If the setting is done incorrectly, this will lead to rapid wear of the teeth, after which the saw will completely fail. Our company offers to order semi-automatic and automatic adjusting machines for band saws to prevent premature wear of the equipment.
How to split a band saw
The band saw on a band saw is a closed, flexible steel band with teeth along one edge. An adjusting machine for band saws will help you set the teeth correctly, which will ensure efficient operation and longevity of the saw.
Tooth set refers to the distance by which the tooth deviates from the plane of the saw blade. The greater the routing of band saws, the wider the cut and, as a result, the engine power should be greater.
The purpose of setting the teeth is to create a gap for the free movement of the saw in the cut. It involves finding a balance:
- creating a reduction in friction (overheating) of the saw when it moves in a cut and increasing the service life of the blade;
- the cut should not be excessively wide so that the effect on engine power is minimal;
- a rationally selected distance will reduce waste (sawdust), which directly depends on the width of the cut.
The size of the band saw layout depends on the size of the workpiece, the type of metal, and its strength characteristics. When cutting large solid metal workpieces, alternating narrow and wide tooth settings are used to avoid the effect of pinching the saw.
Thus, a correctly executed cut on a band saw is the key to successful, high-quality and efficient cutting of the workpiece, which means obtaining elements that meet high requirements.
Operating principle of adjustable machines
The adjustable machine for band saws can be:
- single lever;
- double-lever;
- perform alignment on two teeth at the same time;
- manual;
- semi-automatic;
- automatically.
There are also devices with which you can control and set the band saws. They are installed and secured on the desktop.
The machine for setting band saws, no matter what type it is, has one ultimate goal - to bend the saw teeth to a certain distance. To set this distance, an indicator is used, which is placed in the desired position at the beginning of work and fixed.
Manual machines provide individual setting of each individual tooth using a pusher. The tooth is retracted by an amount larger than required, and when the pusher returns, the tooth springs back several values. Therefore, 2-3 presses are performed, which contributes to a softer bend that prevents breakage. In this case, for correct setting, the teeth are grabbed at 2/3 of the height.
In the automatic setting mode on machines, the saw band is mounted on bars, which are adjusted depending on its length. Then the parameters are set: the number of teeth, the amount of set. The machine itself feeds and counts the teeth, ensures the pusher operates and stops when processing a given number of teeth.
It is possible to stop the device at any point and measure the wiring. The flow meter shows the result of the work performed by the automatic machine. It is possible to set each individual tooth apart, as well as in an accelerated mode, which allows the pushers to simultaneously act on two teeth in opposite directions. Clamping the saw into the machine using a central plate ensures precise results.
The abundance of types, constant improvement and automation of adjustable machines for band saws allows them to perform work with a high degree of accuracy. This will ensure products of excellent quality, which will be sold on the market at higher prices.
Basic selection options

- Maximum saw width. Familiarize yourself with the characteristics of each model: the larger the permissible range, the wider the operating capabilities of the equipment.
- Operating mode. Manual and automatic equipment differ in design, operating speed and cost.
- Design features. Some models are suitable for simultaneously moving two teeth apart, this significantly speeds up the work.
An automatic adjusting machine for band saws will work flawlessly for a long time and will allow you to keep your tools in excellent condition. Such equipment is easy to use and easy to configure; it will be easy to work with.
Cutting part shapes and sharpening angle
At the first stage, the type of band saw is determined. The main indicator is the shape of the teeth. Depending on this parameter, they are divided into dividing, carpentry or intended for sawing logs. The initial geometry and routing angle are determined by the manufacturer. It is recommended to find out this data at the stage of purchasing components. They are needed to determine the machine parameters.
For hardwoods, the rake angle should be kept to a minimum. This ensures optimal contact between the processing material and the metal. If you plan to process soft varieties, you can use models with a larger rake angle to increase processing speed.
The determining parameters for self-updating the cutting edge are:
- tooth pitch. This is the distance between the cutting elements of the structure. Common values are 19, 22 and 25 mm;
- tooth height. The size from its base to its top;
- corner. The main value that you need to know to form the cutting plane. For carpentry models it is 35°. In dividing saws, the angle is from 18° to 22°. In structures for processing timber – 10°-15°;
- divorce. Determines the deviation of the tooth from the general plane of the blade.
After performing work on the machine, ideally these characteristics should remain unchanged. For each model, the manufacturer determines the maximum deviation value. If during operation this is achieved, it is necessary to purchase a new model.
In order to eliminate resonance, some types of cutting tools use a variable pitch of the teeth. This does not affect manual sharpening, but requires careful setting of parameters during automated sharpening.

Is it possible to do without a machine?
Wiring a band saw can also be done using the proven “old-fashioned” method, however, this will require dexterity, skill and patience from you.
The saw is clamped in a vice between two plates of durable oak wood. As a tool for directly spreading the teeth, you can use a metal plate on which cuts of different widths are made. This width corresponds to the thickness of the canvas. The kerf should be placed on the saw tooth and moved in the desired direction. Care must be taken to ensure that each tooth being set has the same angle of deviation from the blade as the others.
Thus, band saws can be cut in different ways depending on your needs and capabilities, as well as on the requirements that the sawn elements must meet. The modern market offers many options for manual, automatic and semi-automatic units, on which the gap meter controls the gap. Everyone can choose exactly the option that suits them best.
Recommendations for sharpening
The correct choice of grinding wheel type is important. It must match the grade of steel from which the band saw is made. Corundum wheels are used for structures made of tool steel. If you want to improve the cutting properties of bimetallic models, you should use CBN or diamond wheels.
Depending on technical capabilities, it is possible to perform full-profile processing or each cutting part separately. In the first case, you will need a CBN circle, the end of which has the same shape as that of the saw. For the second option, each tooth is processed.
You will first need a machine. It must have the functions of regulating the speed of rotation of the disk and changing its location relative to the tool. After securing the blade in a special frame, you should perform the following steps according to the following instructions.
- The emery is directed downwards. At this time, the front face with the cutting edge is processed.
- Forming a cut in the depression. This is done without leaving the canvas. This stage allows you to remove microcracks and irregularities. An important point is the reduction in surface tension, which is the main cause of fabric deformation.
- The circle moves up. The back of the tooth and its cutting edge are ground.
All other teeth are updated using the same method. It is important that the values of the entry and exit angles are the same everywhere. Otherwise, if the geometry differs in one of the parts, performance will deteriorate.
After completion of processing, it is recommended to perform fine-tuning - treat the surface with fine-grained sandpaper. During this process, the geometry of the web should not change.
With prolonged contact of the circle with the metal, the temperature on the surface of the latter can rise sharply. To eliminate this effect, special coolants are used, coming directly from the machine. The feed is carried out continuously to avoid the formation of a glow zone. In this part, the mechanical strength will be deteriorated.
To avoid the appearance of nicks, before processing wood, you need to check for the presence of metal components in it. Also, special attention is paid to fixing and uniform feeding of the workpiece for sawing.
