Angle circular sawmills

Sawmills are one of the best tools for wood processing. This type of technique allows you to quickly and efficiently work with materials of different shapes, lengths and sizes. Sawmills have different types and types of structures, which is due to their scope. Among them are the angular circular sawmills, which will be discussed.

Circular sawmills, unlike standard band models, are equipped with 2 saws. They are in a 90 ° ratio to each other, so they can cut material both horizontally and vertically. Accordingly, the position of these saws is adjusted using the technical devices that are available in each model. At the same time, if the sawmill is equipped with an electronic ruler, then the accuracy of setting the cutting element increases.

First of all, the presence of 2 saws and their location allows you to get wood of different shapes, lengths and sizes.... For example, using the predefined functions, you can make both long and thin boards and square beams of various sizes. And also of the features it is worth noting that it is not necessary to turn the log over in order to saw off a certain part of the trunk. The main advantage of angle circular sawmills, in contrast to standard band saws, is cost-effectiveness

The unique cutting and the ability to manufacture a large number of blanks of various shapes came to the liking of the consumer market, so now coal saw models are in great demand. Naturally, this state of affairs also affected the companies that produce such equipment. The range has expanded, and the number of functions and technologies used during the operation of this type of forestry tool has also increased.

The high quality of wood processing, as well as the ability to manufacture various types of products, make the corner units versatile and at the same time inexpensive. Whereas previously several tools were required for a complete procurement, now all these functions can be performed by one installation. Good margins are important to harvesting and corner models are great for this.

Among the manufacturers, it is worth noting the companies BARS and DPU, whose products are in demand on the domestic market.

• BARS-5 - a two-disk model, distinguished by its configuration, which can be expanded or narrowed, depending on preferences. Radial cutting is possible thanks to 2 cutting elements, each of which is no larger than 550 mm in diameter. As for the diameter of the processed material, the range varies from 100 to 950 mm. An automatic mode is built in, which can be used for fully autonomous operation of equipment. In this case, the maximum material diameter should not exceed 600 mm.

An important indicator is the feed rate, because the performance of the equipment depends on this indicator. For BARS-5, this characteristic is in the range from 0 to 90 m / min, and the total depends on the settings that you specify during operation. In this case, the length of the processed log should be at least 2000 and maximum 6500 mm. As for the preparation of a bar, then a size of 200X200 mm or less is provided for it. The vertical and horizontal saw drives have the same power of 22 kW.

Specific energy consumption is 7 kW / m 3, motors with 2940 rpm. It should be noted that there are 3 complete sets, each of which has its own characteristics. The first is a mechanical system, the second and third are hydraulic, and the latter is equipped with a hydraulic loader... As a result, the weight of each of the models is very different, since in the first case it is 2670 kg, and the maximum indicator is 4050 kg. There is certainly a difference in the total installed capacity.

• DPU-500/600 - domestic angle-turning sawmill, manufactured in 2 modifications. As the name implies, the first has a vertical saw blade diameter of 500, and the second 600 mm. And there is also a difference in size for the horizontal part, which is 550 and 600 mm, respectively. The maximum diameter of the processed log is 800 mm in the first case and 900 in the second.

A key feature of these models is the power of the circular saw motors. For DPU-500 this characteristic is 11 kW, for 600 model 15 kW. It was this change that led to a difference not only in versatility, but also in efficiency. If the motor power of the transverse carriage is the same and equal to 0.37 kW, then the vertical part for a more advanced model was strengthened to 0.55 kW. It should be added that the feed rate of the processed material has not changed either, because 21 m / min is the maximum for both models.

The increase in the capacity of the second unit entailed a change in the possible dimensions of the manufactured products... For example, the maximum dimensions of the exit bar are 210X210 versus 180X180 mm for the first option. The productivity of the edged material is 6–10 and 8–12 m 3 per shift, respectively. The lumber yield is 74% for both models. An important disadvantage of the DPU-600 over its 500 counterpart is its weight of 950 kg, which is 150 more than that of a less powerful specimen.

Thus, having 2 models different in their characteristics, the consumer has the opportunity to choose between performance and dimensions. Of course, a lot also depends on the price of the equipment. If we talk about whether the presented corner sawmills are of high quality and reliable, then it is worth mentioning that this technique is used in a large number of enterprises and factories. This suggests that manufacturers have taken care of the quality and proper operation of their products.

The main area of ​​application of this type of forestry equipment can be called not only industry, but also the creation of various decorative materials, after all, the features of corner models allow you to make small workpieces of different shapes. Of course, such units can be used as classic sawmills for sawing large logs, but this is not their main purpose.
