It is possible to achieve the ideal geometry of the beam only if high-quality woodworking equipment is used. As part of this short note, we will talk about machines for the production of profiled timber, including cup cutters and milling cutters, thanks to which the assembly of a house from finished material can become simple and technological.

List all possible options equipment used for the production of profiled beams is practically unrealistic. Therefore, we opted for the most popular installations from domestic companies. The first three models produced by PP "Diakom".

SPB2

A fairly compact machine (9000 × 1100 × 1200 mm), the design of which includes a 9 m frame and a carriage moving along it, with the help of which two-sided processing of lumber is carried out. Maximum size the section of the workpiece does not exceed 200 × 250 mm, the minimum is 80 × 80 mm. The basic equipment, which does not include knives for planing and profiling, as well as a carriage feed drive, will cost about 200 thousand rubles.

SPB4 Flagman

This machine is classified as a serious industrial equipment designed to solve the problems of small- and medium-scale production of profiled timber. Its dimensions are 5000×2000×1800 mm. The processing of the workpiece is carried out using four blocks with cutters located in pairs in different planes. The maximum size of the workpiece section is a beam of 250 × 250 mm, the minimum is 60 × 100 mm. AT basic configuration such a machine costs about 750 thousand rubles.

OS4-500

This machine is notable for the fact that timber profiling is an additional function for it, the main purpose is log rounding. The issue is solved by replacing the spindle cups with groove cutter cups. The maximum section of the workpiece is 200 × 400 mm, the minimum is a beam of 80 × 80 mm. In the basic configuration, the OS4-500 will cost about 400 thousand rubles.

SF-250

LLC "IzhKomStanko" offers several modifications of machines for the manufacture of profiled beams. The cheapest (economy option) will cost about 180 thousand rubles. The dimensions of the equipment in working form are 9000×1100×1200 mm. The design includes a 9 m bed, a manual feed carriage with two cutters mounted vertically for double-sided processing. For 300 thousand rubles. you can buy a three-sided milling machine equipped with an electric drive for carriage feed. Modification of SF4-250 for 375 thousand rubles. provides four-sided milling of workpieces. This became possible due to the presence of two carriages in the design. In all three cases, the minimum width of the workpiece is 100 mm, the maximum is 250 mm.

Cup cutting machines

One of the most dangerous places in a log cabin is its corners. The danger lies in providing minimum losses through these parts of the house is not so easy. In order for the house to turn out to be truly warm, corner joints must be made through complex locks formed by cutting the bowls.

MChS-B and MChS-2B

We invite you to familiarize yourself with the capabilities of two simple cup-cutting machines from IzhKomStanko: MChS-B and MChS-2B. The difference between them lies only in the fact that the first modification is capable of cutting a one-sided groove, and the second is a two-sided one. The cost of basic equipment is 95 thousand rubles. and 150 thousand rubles. respectively. A change in the configuration endows such equipment with universal features: it becomes possible to drill holes for fastening the beams with dowels, independence from power supply systems. This is one of the simplest and cheapest cup cutters.

WRC-7 and WRC-15

The machine from the company STIN LLC with dimensions of 1850 × 1700 × 1620 mm is used at woodworking enterprises for milling straight corners and dovetail joints - for inserting partitions and floor logs. Minimum dimensions sections - 100 × 100 mm, maximum - 200 × 200 mm. VKR-15 is another machine from the Kirov company, which is used to make horizontal grooves on both sides (bowls). The maximum section of the workpiece is 200 × 200 mm.

cutters

On sale there are cut kits designed to process a beam of a certain width: 85 ... 210 mm - and give the section the necessary geometry of the Finnish or german profile. The wider the possibilities, the more expensive these products. They are supplied assembled in a set of 2 spindles: one cutter cuts the middle part of the timber, the rest are responsible for forming the edge of the profiled part. The cost of sets starts from 45 thousand rubles. and further - as the width of the processed workpieces increases.

Flagship 4x240, timber profiling

Flagship is a specialized four-sided machine for profiling building timber. The enterprise, the only one in the Russian Federation, has mastered the production of a specialized four-sided machine for the manufacture of profiled construction timber (Flagman series). The supply of the workpiece (bar) to the Flagman machine is carried out using a pusher (boom), which allows the processing of a bar of any size and freeform sections, incl. with a very large thickness of the layer of material being removed (up to 50 mm) (for a four-sided machine of a traditional design, this is a cosmic value). Boom pusher provides uniform supply of the workpiece under any conditions, including the workpiece (beam) with a significant deviation in geometry. The machine quadrilateral Flagman 4х240 is intended for profiling of a construction bar. The maximum cross section of the beam is determined by the configuration of the machine. The machine is used as the basis of a high-performance complex for the production wooden houses from glued or massive timber. On the quadrilateral machine it is possible to make building timber various shapes. The cross-sectional profile of the beam is determined by a set of tools installed on a four-sided machine.

Design and operation principle of a four-sided beam profiling machine

Machine Flagman 4x240 belongs to the class of heavy quadrilateral machines. The frame of the machine is welded from a large number large-section square pipes in a special way to ensure maximum geometric rigidity. The design of the frame guarantees the complete absence of excessive vibration during the operation of the machine. The workpiece is processed from all four sides in one pass. The workpiece is fed from the end by a special swept pusher, the speed of the pusher is regulated by the operator. The pusher does not lose contact with the workpiece throughout the entire processing cycle. At the end of processing, the pusher quickly returns to its original position. The guide rail, top pressure rollers and side rollers ensure the stability of the workpiece during processing. The sectional profile of the manufactured products is determined by the tool installed on the machine. Each machining spindle has a chip chute. Working surface tables, machining spindles, guide bar, pressure rollers and rollers - all elements of the machine are adjustable.

Advantages and features of the four-sided machine

• The main advantage of the design of the flagman 4x240 beam profiling machine lies in a very reliable system for feeding the workpiece during processing: a long pusher on the carriage pushes the workpiece through all the spindles, providing a constant force and feed speed, which is impossible to achieve using feed rollers and ripples. Accordingly, a stable surface quality is ensured over the entire length of the resulting timber. A frozen or not too even beam - it does not matter for the pusher, the feed is guaranteed to be stable and clear. The return of the pusher to its original position occurs on top speed in 10-15 seconds. Only such a feeding system makes it possible to produce complex sections, for example, with one or even two side semi-circular sides for a "block house", while guaranteeing an accurate geometry and the complete absence of dents and other marks from the feed rollers on the finished product.
• The feed by the pusher also allows you to increase the "fool protection": the force on the pushing carriage is transmitted by means of a chain (rail) rigidly fixed on the feed table and a drive sprocket. The sprocket is pressed against the chain by a spring, and at a certain rolling resistance (for example, someone forgot to reconfigure the pressure rollers to a larger section), it simply wins back, disengages from the chain and turns. This solution protects the elements of the machine from careless handling.
• The position of all working elements of the machine: spindles, table surface, pressure rollers and rollers, the guide bar is adjustable. You can always adjust the optimal relative position of the elements for a comfortable and quality processing blanks of a wide range of sections.
• The design of the machine frame, in addition to the required rigidity, also provides quick and easy access to all elements of the machine: adjustment, maintenance and, if necessary, replacement of machine parts are not difficult and will not require much time.
• The adjustable workpiece feed rate allows you to select the optimal operating modes depending on various conditions: the size of the workpiece section, the removal depth, rock hardness, etc.

Beam sections that can be made on the machine

The standard machine is designed for the production of profiled timber with a width of 90 to 240 mm and a height of 140 to 200 mm with flat sides. At the request of the customer, the dimensions of the sections can be increased, and the shapes of the sections can be changed. With a certain modification, it is possible to manufacture a bar with one or two radius (or curly) side surfaces. The profile section and the specific size is determined by the tool installed on the machine.

Recommended to purchase additional

The capabilities of the machine in the basic configuration can be significantly increased, so we additionally recommend purchasing:

• Workpiece length. If it is necessary to process a beam longer than 6.5 m, the infeed table is extended to accommodate a beam of 8.5 m, 10.5 m, or 12.5 m.
• The maximum width of the processed timber. The width of the beam is the most important parameter that determines the actual thickness of the building wall. In the basic configuration, the maximum width of the finished timber is limited to 240 mm, which is sufficient in 95% of cases. However, if it is planned to manufacture products (beams, or profile carriages) of greater width, this value can be increased.
• The maximum height of the processed timber. The greater the height of the beam from which the structure is made, the less potential places for heat leakage in the walls, the easier it is to achieve high energy efficiency parameters of the structure. In the basic configuration, the maximum height of the finished timber is limited to 200 mm, which is sufficient in 90% of cases. However, if it is planned to manufacture a beam of greater height, this value can be increased.
• Spindle drive power. In the production of profiled timber, the workpiece is based on two planes: right and bottom. On these sides, the minimum removal is adjusted so that the workpiece does not skew. Ideally, material removal from all sides should be minimal, as this is beneficial from an economic point of view, but for a number of reasons, in practice, I will usually eat more from the upper and left parts of the timber. Firstly, most construction timber profiles themselves suggest the greatest removal from above (the cavity for insulation is most often selected from above), and secondly, if the original workpiece has a certain curvature, or is sawn with too much margin, all this removal falls precisely on upper and left spindle, because to the right and bottom, the removal is always limited to a certain minimum value. In this regard, the drive power of the upper and left spindles is usually greater than the drive power of the lower and right spindles. The power of the motors in the basic configuration is optimal based on such parameters as performance, energy consumption, cost, load on the tool. However, if you want to increase the potential productivity of the machine, you can install more powerful motors that will allow you to increase material removal or increase processing speed.
• The cross-sectional shape of the resulting beam. In the basic configuration, the machine is designed to produce profiled timber with straight side surfaces. With a certain refinement of the pressure rollers and the guide line on the machine, it is also possible to obtain a bar with one or two side surfaces of an arbitrary shape. The specific profile of the beam is determined by the tool installed on the machine.
• Tool. The cost of the basic configuration includes side vertical drums with straight blanket knives that process the side planes of the timber. For the manufacture of timber, milling cutters for horizontal upper and lower spindles are also required, which will determine the profile of the finished product. There are several standard kits to choose from: "H" stands for tungsten carbide-tipped router bits. Such cutters are the most affordable, but after grinding the soldering, you need to buy new ones. The letter "M" denotes cutters with mechanical fastening of knives. This type of milling cutter is more expensive, but overall operation will be cheaper in the end. the cost of knives is usually lower than the cost of cutters with t/s soldering. The cutters marked with the letter "P" with t / s cutting inserts are the most serious tool in machines of this class and the cost of these cutters is appropriate, but the operation will also be more profitable in the end, because. the cost of sets of cutting inserts is lower than the cost of whole cutters with soldering. If a special profile of the product is needed, for example with one radius side, then the tool will need to be selected accordingly. Our experts will help you choose the best tool for solving your problems.
• Compensation saw unit. To select a compensation cut, which reduces the likelihood of cracks in the material of natural moisture, an appropriate unit is installed.
• CNC module A1. In real-time mode, it automatically determines the load acting on the tool and, in accordance with the received data, adjusts the processing speed. With a fixed power of the motors of the cutters, the maximum amount of wood removed is limited. Therefore, the greater the thickness of the layer to be removed, the lower the processing speed should be. The Flagman machine, equipped with a workpiece feed drive with the possibility of smooth speed adjustment, allows the operator to control the processing speed depending on how much wood needs to be removed at the moment. But the operator objectively cannot absolutely accurately maintain the optimal processing speed. At some points in time, the speed will be higher, and at some times it will be lower than the maximum allowable speed. At a speed below the optimum, the machine is operating below its capacity, not doing the amount of work that it could do. At a speed above the maximum, an overload occurs, which puts the machine in an "extreme" mode, which negatively affects the life of the main components (tools, motors, spindles). Control system block Module A1 allows you to monitor the current load on the cutter motor and, depending on it, automatically change the feed rate of the pusher. Using this unit is the most cost-effective way to increase machine productivity without increasing power consumption. In addition, the use of this block eliminates the possibility of extreme overloads, which increases the life of the machine and reduces the likelihood emergency situations. Control unit Module A1 is switchable, i.e. The operator can at any time turn off the automatic feedback and continue processing manual mode. One unit Module A1 is connected to only one motor. When profiling a classic beam, the maximum load usually falls on the upper motor, to which the Module A1 should be connected in this case. If the maximum load can often fall on different spindles, it makes sense to install the feedback system Module A1 on several motors.
• Reception table. During processing, the workpiece, passing through the machine, at the exit must be supported by a receiving table, from which the finished product is then removed.
• Sectionalization of the bed. When ordering, you can limit the maximum length of one section of the machine bed so that it can be transported by a certain truck or railway container.

Profiled timber is made according to the technologies of our time, using modern equipment. Log houses are environmentally friendly and have high-quality thermal insulation. His correct form in geometric terms, it makes it possible to build from this material, both large cottages and small structures. All this makes the production of repair profiled beams now very cost-effective. The machine for the manufacture of profiled timber, although expensive, is instantly reimbursed. This makes everything much more interesting for individual traders like this business. What equipment is needed for the production of corrugated timber and how much does a machine for the production of corrugated timber cost, let's look at it in detail.

The production of profiled timber is a very multi-stage and not an easy process. For its implementation, a machine is required in order to manufacture. They make such a product from coniferous wood, for example, larch, cedar, spruce, pine.

In the first stages, all raw materials are sorted in production and are already selectively fed to the frame machine. There, the tree trunk is peeled and sawn off.

Often, more than one type of technique is used to make. One of these machines is the apparatus for profiled timber. The log is sawn from four sides and then it is profiled. To obtain a dry bar before profiling, the raw material enters special chambers. And only then profiled.

All production of profiled timber can be divided into stages:

1. Finishing raw materials on a multi-blade machine.
2. Finishing on a four-sided milling machine, where the bar is planed and profiled.
3. Designation and trimming of a ready-made profiled beam.
4. A cup is cut out, an interventional connection.

Milling woodworking machine

But there are machines that allow you to do all these stages on one machine with one log installation. Machines of this type are called milling multifunctional devices. This technique is equipped with removable tools that change before each new finishing step. The quality of the resulting profiled timber is affected by the quality of the cutter used on similar equipment.

Grooving knives on a similar machine are of a removable type and have a different profile. Therefore, without much effort, you can get a thermal lock from a conventional single-groove to a complex “comb” shape. This provides an increase in the range of goods in production to the limit and increases the profitability of production.

It is necessary to consider briefly the very popular models of machines for the manufacture of profiled timber.

If we declare the cost of machines for the production of profiled material, then they depend on the power and practicality of the equipment. But the more purposes such equipment has, the more profitable the production will be. And this will attract customers and give a quick payback for the enterprise itself.

1. The main advantage of the design of the flagman 4x240 beam profiling machine is very reliable workpiece feeding system in processing: a long pusher on the carriage pushes the workpiece through all the spindles, providing a constant force and feed speed, which is impossible to achieve using feed rollers and ripples. Accordingly, a stable surface quality is ensured over the entire length of the resulting timber. A frozen or not too even beam - it does not matter for the pusher, the feed is guaranteed to be stable and clear. The return of the pusher to its original position occurs at maximum speed in 10 - 15 seconds.

Only such a feeding system makes it possible to produce complex sections, for example, with one or even two side semi-circular sides for a "block house", while guaranteeing an accurate geometry and the complete absence of dents and other marks from the feed rollers on the finished product.

2. Feeding by a pusher also allows you to increase the "fool protection": the force on the pushing carriage is transmitted by means of a chain (rail) rigidly fixed on the feed table and a drive sprocket. The sprocket is pressed against the chain by a spring, and at a certain rolling resistance (for example, someone forgot to reconfigure the pressure rollers to a larger section), it simply wins back, disengages from the chain and turns. This solution protects the elements of the machine from careless handling.

3. The position of all working elements of the machine: spindles, table surface, pressure rollers and rollers, guide rails are adjustable. You can always set the optimal relative position of the elements for comfortable and high-quality processing of workpieces of a wide range of sections.

4. The design of the frame of the machine, in addition to the required rigidity, also provides quick and easy access to all elements of the machine: adjustment, maintenance and, if necessary, replacement of machine parts are not difficult and will not require much time.

5. The adjustable feed rate of the workpiece allows you to select the optimal operating modes depending on various conditions: the size of the workpiece section, the removal depth, rock hardness, etc.
