Corner disc sawmill, rotating

Corner disc sawmill

This device is distinguished by the presence of two saws, which are located at an angle of 90 degrees. to each other. The cut occurs in both directions. One pass yields one edged board. Angle sawing is slightly different in operating principle from conventional circular sawing. The corner sawmill makes it possible to cut without turning the log. These sawmills can be called the most economical, because the yield of finished lumber reaches 60 - 80%. The cost of a circular sawmill largely depends on its functionality, performance and additional parameters.

A device for making angled cuts is indispensable in sawmill production. Longitudinal sawing of round workpieces and their production with specific geometric parameters on a corner sawmill, in comparison with conventional methods of cutting wood, is carried out due to a number of distinctive characteristics. Such a device easily replaces several machines at once.

Lumber of various sections and dimensions can be produced on a corner circular sawmill as a result of independent movement of vertical and horizontal saw supports. In this case, no time is wasted on turning over or reinstalling the workpiece.

Due to the fact that longitudinal sawing occurs without idling in both directions, the final sawn timber is distinguished by the exceptional quality of the sawn surface. Radial and tangential lumber on such a device have a maximum yield.

There are also single-saw devices. In such machines, cutting occurs using one disk, which is mounted on a rotating mechanism in both directions. There is no idle speed. The movement of the saw blade begins in a horizontal position. When moving forward, a horizontal cut is made along the length of the log. At the end of the log, the saw rotates into a vertical position in one movement. When the carriage moves back, the notched part is cut off by vertical cutting. Afterwards, the disk is turned again to a horizontal position and the cutting cycle is repeated. This sawmill quickly cuts the workpiece to produce edged lumber of the required section.

One sawing cycle: moving forward, turning the saw, moving backward for a six-meter workpiece takes 1 minute.

Design of coal disc sawmills

To make it easier for you to understand what this kind of tool looks like, just imagine a machine that actually makes longitudinal cuts in wood. Also important is the fact that it operates from an electric motor (like electric saws).

It is worth noting that the circular sawmill can be represented as two working bodies or as one working body. With one such “organ”, a cut is made in both horizontal and vertical positions. The most unusual thing about this option is that this kind of sawmill does not have an idle direction.

When the sawmill has two disks (organs), then in this case the workpieces are fed in an orthogonal direction. That is, a pair of worker disks have both a vertical and horizontal arrangement relative to each other. Thanks to this kind of feature, high-level performance is fully ensured.

Equipment and operating features

Using a corner sawmill you can create:

edged lumber, including radial
various blanks for molded products
multilayer timber
parquet
individual log cutting map with waste rejection.

The corner rotating sawmill will help to achieve high precision in comparison with the band sawmill. The design of the angular disk machine guarantees an optimal solution to the cutting pattern of the workpiece, a rational output of edged materials and eliminates idle running.

Advantages over band sawmills:

high level of reliability
obtaining high-quality edged boards with the least amount of waste
the log is sawn in one installation, there is no need for turning and turning over
Thanks to the high quality of sharpening of the discs, high cleanliness of processing is ensured.

Control over the cutting process and the state of equipment is carried out by an operator located in a special mobile cabin. The logs are fixed using reliable clamps that firmly hold the workpiece.

Most often, the drives of such sawmills are equipped with motors with a controlled rotation speed using a frequency converter in order to determine the angular speed of the working power plant and automatically control the feed speed of the saw spindle. As a result, the most suitable sawing speed ratio is obtained, taking into account the hardness of the timber and the choice of circular saw.

The best modern models of circular sawmills

Now let’s actually get acquainted with some models of this kind of tool, which are famous not only for their power, but also for being quite practical and productive. Because perhaps among these models you will find the most suitable sawmill for yourself and your professional needs. So let's get started.

If you have just purchased a chainsaw, then the first thing you need to know is how to start it.

If your chainsaw suddenly stops starting, read our article to find out what to do.

Chainsaw attachments are an indispensable thing if you want to use the chainsaw for other purposes than its intended purpose, but, for example, as a mower.

PDPU 550

This model is one of the representatives of radial orthogonal sawmills. It has one disk and its main activity is cutting through the use of a log saw into cut-off lumber.

Moreover, the device has a saw unit that is mounted on a carriage and has the ability to move in both vertical and horizontal positions relative to the wooden material. In addition, the tool can perform sequential cuts in perpendicular planes.

And thanks to the electric drive chain transmission, the saw unit can rotate ninety degrees. The material that actually needs to be cut is attached to the guides using special clamps. Moreover, the peculiarity of this model is that during the process of sawing the log material there is no need to re-fasten it and turn it over.

If we talk about the movement of the vertical carriage, then it is carried out along the portal itself, namely along its rocks through the influence of a chain mechanism that has an electric drive.

And the movement of the saw unit in a relatively horizontal position is carried out thanks to a chain transmission. The highest dimensions of saw material that can be obtained thanks to this model are 180x180x6000 mm.

It is worth noting that the movement of this kind of tool relative to the guides themselves is performed through manual work . But if you, for example, want to significantly increase the actual productivity of the tool, then in this case you can install a sawmill feed of a mechanical nature.

In addition, it is worth noting that this model has a full cutting cycle relative to the reverse and forward direction of movement of the portal itself.

Now let’s actually look at the technical characteristics of this model, so:

Processed log (diameter) – 800 mm;
Processed log (length) – 6000 mm;
Silt disk (length) – 550 mm;
Saw motor power – 11 kW;
Nodal rotary drive power – 0.25 kW;
Motor power when moving the carriage vertically – 0.37 kW;
The final beam (max. dimensions) – 180x180 mm;
Overall dimensions of the machine – 1400x1900x1600 mm;
Rail track (length) – 10,500 mm;
The dimensions of the machine are 600 kg.

WOODVER UDP2-550

This model is universal and is used for sawing round timber. It also produces edged lumber at the highest level through the use of automatic and semi-automatic modes.

This kind of tool is widely used in various enterprises whose main activity is woodworking. And also in companies, the basis of work is the workpiece, which in turn is used in the manufacture of molded products, furniture panels, laminated veneer lumber.

If we talk about the sawing process itself, it consists of the following: the log must be installed and securely secured on the machine , namely on its frame using centering screw clamps. After which you need to set the necessary parameters for the sawing itself using a special remote control, and only after that you can start the mechanism itself.

It is important that sawing of the material is carried out in a systematic manner through the use of both discs. One of which is located on the plane vertically, and the second - on the horizontal. A special feature of this device is that it does not produce idle strokes. It is for this reason that the sawing itself is carried out both in the forward and in the reverse direction.

After you remove the board, the automatic disc positioning cycle will begin feeding the cut again . As for the microprocessor system, which is actually installed by the manufacturer on the machine itself, it makes it possible, within acceptable limits, to control what size you set.

Since there are special sensors on the device itself, which actually have accurate cutting data. The sawmill produces a yield that is eighty percent.

It is worth noting that the size of the timber, namely the most permissible one, is 180x180 mm , and if we count with the disks included, then the parameters are 220x220 mm. Moreover, one cannot ignore the fact that this model has cards designed for cutting material. And besides, they are quite convenient to use.

In addition, everyone has the opportunity to choose for themselves the most effective and convenient cutting options with the maximum yield of final material. You can see a demonstration of the work in the video:

Ts2UBS-2

First of all, I would like to draw your attention to the very cost of this instrument, which is significantly lower than that of its “brothers”. Since it has constructive solutions and production organizations, when other models are equipped with operating and technical parameters.

Moreover, it has a small weight and dimensions of the machine itself .

It is for these reasons that this model is widely used in the mobile field. Since you can install the tool on a subframe, specially made for transportation using a drag along the plot itself.

Therefore, you simply do not need to install the tool, and all that is required of you is simply to connect the electrical power.

It has a significant size of lumber, which is 200x200 mm, given that it is equipped with saws of small diameter, which is only 550 mm. In addition, each tool assembly is adjustable, so you can easily control the gaps and backlashes.

DIY corner sawmill

A corner circular sawmill, the self-made drawings of which are available in large numbers on the Internet, is an indispensable device for those who want to start building a house or connect their life with woodworking.

Buying a corner sawmill is an expensive business. Therefore, for personal needs, it is more advisable to make it yourself, especially considering that a drawing of a corner sawmill is not difficult to find on specialized sites. However, you can independently draw up such a drawing, design the device and assemble the structure.

Important steps in assembling a homemade circular sawmill:

you need to create a strong metal frame, for example, from any metal pipes or guides
so that the pipes are connected in the most reliable way, it is better to weld them
Experts advise using high-quality rails without external defects as guides, otherwise the carriage wheels will always jump off and get stuck.
the carriage can be assembled from metal parts
When creating a sawmill, be sure to pay attention to the fact that the geometric shape of the frame with built-in rollers or wheels must fully correspond to the distance between the finished rails. This way the carriage will move smoothly and freely
Any gasoline engine can be used as a motor. The power unit must have high power
To avoid the possibility of motor overheating, it is worth replacing the chain drive with a more reliable and durable analogue. After this, the machine will become safer and its service life will increase.

Advantages of the SEVER 550 circular sawmill over similar competitive machines:

Sever 550 disk corner sawmill over other single-disc sawmills with a rotating mechanism is the well-thought-out ergonomics of the machine, which entails an incomparably higher level of ease of use on the sawmill, which in turn, naturally, directly affects the productivity of the machine.

The operator working on the Sever 550 walks inside the frame on a special flooring, which ensures comfortable and free movement even in winter.

The rotating mechanism is designed in such a way that the circular saw is rotated with one movement of the operator’s hand, unlike models of single-disc rotary sawmills from other manufacturers, in which, in order to rotate the saw, the operator needs to approach the saw unit from the side, unscrew the lock, rotate the unit, tighten the lock (all this occurs in a dangerous inclined position above the saw) and only after all these by no means instantaneous manipulations is the carriage ready for the next cut. The operation of turning the disk on such sawmills takes from 10 to 15 seconds, while on the Sever 550 , moving the disk from a horizontal to a vertical position (or vice versa) takes no more than 1 second!

Sever 550 corner disc sawmill is equipped with a special adjustable movable limiter for the lateral movement of the saw unit, which allows you to literally move the saw unit to the side with your eyes closed, setting the next thickness or width of the board, while guaranteeing absolute stability and identity of these dimensions. Operating principle: the limiter is adjusted to the appropriate size (taking into account the thickness of the cut) of the board, for example, a thickness of 50mm, and when subsequently moving the saw unit, simply move it all the way and you can cut the next board. While the cut is being made, the limiter moves further to the side until it stops and is fixed. The saw unit can again be moved until it hits the stop to get a board exactly the same size as the previous ones. This device allows you to significantly reduce the likelihood of operator error and always obtain products of accurate and stable dimensions.
