It is possible to achieve ideal beam geometry only if you use high-quality woodworking equipment. In this short note, we will talk about machines for the production of corrugated timber, including cup cutters and cutters, thanks to which the assembly of a house from finished material can be simple and technologically advanced.
What equipment is needed for production
To manufacture such products you need the following equipment:
- Disc sawmill.
- Profile beam cutting machine.
- Four-sided milling machine.
- A machine for cutting cups in timber or manual cup cutters.
To produce this profiled lumber, you first need a sawmill. Here a four-sided beam will be cut from solid wood. Already from this blank a mold with a groove and a tenon is made on a four-sided machine. And, of course, a cup cutter, which will be used to cut out connecting parts at the last stage of manufacturing.
If the company produces not only profiled timber with natural moisture, but also dried timber, then special drying chambers will also be needed. And production will take place on the same machines as for material with natural moisture. Simply, before profiling, the workpieces will undergo chamber drying. And we have already talked more than once about the advantages of building from dried profiled timber.
Today, equipment for the production of such material is constantly being modernized. And machines are becoming increasingly popular - universal ones, which perform most of the work on the manufacture of such goods and make it possible, by purchasing just one equipment, to perform all the work from wood processing, splitting and milling at the same time.
Profiling – cantering machine Wood-Mizer MP-100
This technique is necessary for companies that have small production of profiled lumber. It has a bed where the workpiece is loaded using a saw carriage, and a cutter log. There is no need to load the workpiece onto such a machine manually, since it is automated.
Since the cutters of this technique are adjustable, you can get up to 10 types of profiles. This provides production with an immediate increase in choice, which means increased consumer interest. And due to the automation of loading and unloading of the machine, labor productivity will be increased by approximately 30%. Characteristic feature Value Number of cutters 4 pcs. The frequency at which the cutter rotates is 4890 rpm Required electrical power 4x2 kW Machine size 9500x11500x1000 Weighs 10 tons
Purchase this equipment in the Russian Federation from companies engaged in forest processing automation. This kind of car costs from 350-400 thousand rubles.
If we talk about the costs 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 provide a quick payback for the enterprise itself.
Sawmills for the production of profiled timber
At the first stage of production, the wood goes to the sawmill. Here it is sawed and filed, giving the correct quadrangular shape. The round timber will fall onto the beam, where it will unravel into a beam of a given cross-section.
Choosing high-quality equipment for such production seems to be simple, although many companies offer band sawmills of different configurations and at different price categories. But not every equipment produces high-quality timber, which means the finished product will be of low quality. This means losing customers and creating a bad reputation in the market for these products. When purchasing a sawmill, you don’t need to skimp. With cheap equipment it will not be possible to produce products that meet all standards and qualities.
When choosing a sawmill, pay attention to the following elements:
- Sawmill portal.
- Vertical guides.
- Mechanism for moving in a vertical plane.
- Pulleys and rollers for band sawmills.
The portal of a high-quality band sawmill should be made of a square pipe and have reinforcing elements. If there are no reinforcing elements, then the equipment will be cheaper, but problems may arise in operation. Wood is a fairly heavy raw material, and during operation, a portal that does not have amplifiers can quickly become deformed. A sawmill is purchased for more than one year and must serve its owner for a long time and produce high-quality profiled material.
Vertical guides must be made of solid metal and ground. In inexpensive equipment, the guides are made of pipe, which quickly deforms.
The pulleys on which the saw blade moves must have a diameter of at least 50 cm. The engine pulley is at least 14 cm. In this case, the rollers for moving and guiding the saw blade must be adjusted, and the more adjustments there are, the better the machine.
Distinctive characteristics of corrugated timber production
The production of corrugated timber is a very multi-stage process and not an easy one. To carry it out, you need a machine to make it. Such a product is made from coniferous wood, for example, larch, cedar, spruce, pine.
In the first stages, all raw materials are sorted in production and selectively supplied to the frame machine. There the tree trunk is peeled and sawed.
Often, more than one type of technology is used to produce. One of these machines is a machine for corrugated timber. The log is sawn on four sides and then profiled. To obtain a dry bar before profiling, the raw material enters special chambers. And only then is it profiled.
All production of corrugated timber can be divided into stages:
- Finishing raw materials on a multi-rip machine.
- Finishing on a four-sided milling machine, where the block is planed and profiled.
- Marking and trimming of ready-made corrugated timber.
- The cup and inter-crown connection are cut out.
Four-sided machines
[ads1]On a four-sided machine, a profiled beam acquires a groove and a tenon, as well as two smooth planed sides. These two sides can be either flat or semicircular for block houses. First, the timber is profiled and then planed. But there are machines that perform these actions simultaneously. Such machines are called universal. It is best to purchase such equipment, it will greatly increase labor productivity.
The quality of such equipment depends on the quality of the cutter that will process the profiled timber. The more attachments a machine has, the greater the range of timber that can be produced on it. This means attracting more buyers with different requirements.
Typically, when choosing this equipment, you should pay attention to:
- The presence of several cutting cutters. The more attachments on the cutter, the larger range of profiled timber you will receive.
- Carriages feeding material. It can be automatic or manual. There is no need to explain how to increase labor productivity by having automatic material feeding.
Machine for the production of profiled timber SPB-200A
This technique is used for processing and profiling the bar on 4 sides. This version of the machine is intended for finishing material with natural moisture or dry workpieces measuring 200x250 mm. Suitable for both small private farms and large sawmills. The machine is small in size, which makes it possible to place it on an area of 11 meters.
Important properties of the machine can be presented in the form of a table: Characteristic feature Value Number of cutters 2 pcs. The frequency at which the cutter rotates is 4580 rpm. The required electrical power is 7.5x2 kW. Machine size 10500x1300x900. Weighs 760 kilograms.
Advantages of this machine model:
- Calibrated guide frame.
- Easy replacement of one attachment for another.
- Not very difficult to operate and maintain.
- Low cost.
The average cost in the Russian Federation is 150-165 thousand rubles. The operation of such a machine can be seen in the proposed video:
Machine or hand tool for cutting cups
Equipment for the production of profiled timber includes cup cutters. They are used to make reliable and aesthetically beautiful connections between materials. High-quality cup cutters allow you to make connections professionally. Of course, such connecting connections can be made using available tools, but this is quite difficult. And if the connecting parts are not done correctly, you may end up with parts of the material that do not fit together or fit poorly. And this will undoubtedly have a detrimental effect on
Manual chakshkorez differ from machine tools primarily in their mobility. And this is convenient when building a house from profiled material.
Using cup cutters you can do this job perfectly. This equipment must have different attachments: straight and oblique cups, different angles of inclination. Cutting with cup cutters usually has a range from 3.8 – 24 cm. This is quite enough when building a house from timber.
Machine for profiling bars SPB-200
This technique is necessary for processing and profiling natural moisture and dry raw materials. Used for woodworking with a width of up to 220 mm.
This mechanism consists of:
- Bar stand.
- Stops and clamps.
- A carriage with traverses placed on it.
- Motor.
- Milling cutters.
Important properties of the SPB-200 machine can be presented in the form of a table: Characteristic feature Value of quantity many most 2 pcs. The frequency at which the cutter rotates is 4500 rpm. The required electrical power is 7.5 kW. Machine size 9000x1400x1200. Weighs 550 kilograms.
The advantages of this equipment:
- The cost is low when compared with similar devices.
- You can finish either a dried bar or one with natural moisture.
- Unlike 4-sided machines, it corrects the curvature of the workpiece.
- Can be placed in a small area, 7 meters.
- Replaceable cutters.
- Has a great payback.
Watch the video for work on SPB-200:
The cost of such a machine in the Russian Federation is now on average 145-250 thousand rubles.
Universal machines
Today, technical progress has stepped far forward and there are machines for the production of universal type profiled timber. Such equipment occupies the entire set of equipment with one machine. The wood enters the universal milling machine as a log and ultimately comes out as a finished profiled beam. Replaceable copying knives on such equipment allow you to obtain various types of timber profiles.
Of course, such equipment is not cheap, but if you count how many machines it replaces, the price is quite reasonable. Such equipment has a huge advantage - it can be placed in a small area. And high-quality cutters, which have several adjustable positions, allow you to obtain high-quality products.
When choosing such a machine, you need to pay attention that the equipment has a speed controller. This will help you choose the right mode for a particular type of wood and will give smoothness and accuracy when processing the workpiece.
Which equipment is most suitable for your production will depend on both the amount of money available and the area where you plan to locate your enterprise. When choosing, it’s worth remembering one thing: the purchased equipment should last more than one year, which means you shouldn’t save.
VPK340 and VPK beam profiling machine
This complex includes two machines. They both have four horizontal milling heads. The material is profiled using a similar technique on 4 sides. In the machinery mechanism itself, milling heads first process the block vertically and then horizontally. Machines in pairs are used to finish 4 workpieces at once.
Important properties of the machine complex can be viewed in table form: Characteristic feature Value VPK340 Value VPK Number of cutters 4 pcs. 4 things. The frequency at which the cutter rotates 4700 rpm 4750 rpm Required electrical power 2×110 kW 2×75 kW Machine size 13500x11000x1000 14500x11500x1000 Weight 10.4t 14.4t
The advantages of this complex:
- You can finish 4 workpieces in parallel.
- Processes the block from four sides to depth and adjustable height.
- Has good power.
Each machine from the complex costs 100-150 thousand rubles, which means the cost of the complex will be approximately 300 thousand rubles, but since the productivity will also be twice as high, the payback is relatively rapid.
Production room
Woodworking workshop
To organize the process of manufacturing laminated veneer lumber, it is necessary to take into account fire safety requirements - the cladding of walls and floors must be made of fireproof materials - brick, tile, concrete. It is necessary to maintain the air temperature within 18 ° C. The room must have a powerful ventilation system, a three-phase electrical network, water supply and sewerage. It is necessary to consider convenient access roads for unloading materials and loading finished timber.
Features of house kits
The construction of timber houses from ready-made house kits has become especially popular. They are a set of elements that allow you to assemble the entire structure without special preparation and processing. Essentially, it is a prefabricated house, made in a factory according to a specific design, but then disassembled into its component parts for ease of transportation. Each part has clearly defined dimensions and connecting elements (tenons, grooves, “bowls”, holes for dowels, etc.). The timber is trimmed and has undergone special processing.
A typical house kit consists of the following elements:
- a set of beams for assembling the external walls of the log house and internal partitions;
- lower (flashing) crown;
- kit for installation of subfloor, floor joists;
- floor beams and support pillars;
- roofing details, incl. rafters and sheathing;
- ceiling cladding;
- connecting parts (dowels, staples, etc.);
- additional elements (waterproofing, insulation, etc.);
- impregnation compositions (bioprotection, fire protection).
Assembly instructions must be included.
House kit assembled
Sometimes the manufacturer offers an extended house kit, including additional parts:
- elements and materials for building a foundation;
- roofing;
- stair elements;
- window and door blocks;
- external and internal finishing, decorating elements.
Important! In the production of wooden elements, 3 main types of wood are usually used: pine, cedar and larch.
What does the production process include?
First, let's look at what operations the production of profiled timber includes:
| Procurement of material | Everything here is extremely simple - for work you need wood, which is harvested by specialized forestry enterprises. The best types of wood for timber are pine, spruce, larch and cedar, so work should begin where there are no problems with wood, otherwise transport costs will significantly increase the cost of production |
| Preparing elements | It is impossible to cut a finished product from a log; you need to cut the round timber into pieces of the required size, and for this purpose special installations are used, which can have very different designs. It is important that the prepared elements are cut as accurately as possible, without distortions or distortions |
| Drying of raw materials | In order for the product quality to be at the highest level, it is necessary to properly dry the workpieces. This can be done in two ways - either naturally (in special stacks under canopies without access to direct sunlight), or in a chamber that provides better drying conditions and allows you to maintain optimal parameters of the elements |
| Profiling | At this stage, the products are given the desired configuration, this can be done either in one or two passes, depending on the type of equipment, after which the timber can be used to build a wide variety of structures |
Important! It is not necessary to have all the equipment described above; some manufacturers simply purchase prepared and dried workpieces and process them. Profiled timber costs much more than regular timber, so this option is also profitable and economically feasible.
Drying is a complex process in which it is important to maintain optimal temperature and air humidity parameters
