Four-sided woodworking machines. Four-sided woodworking machines Control and safety system

Improvement technological processes complicates the equipment, increases the productivity of an individual unit. IN carpentry four-sided machine woodworking combined previously separate operations on one table with a single pass of the workpiece. Cleanliness and precision of processing meets established quality standards.

Possible processing methods

Various heads with blades of different profiles can cut the layer from 4 sides of the blank:

• milling Performs only longitudinal cutting of wood under the groove. A disk-type cutter performs the task of cutting the board. To do this, clamps for the outgoing strips are placed on the receiving side of the table;
• planing;
• jointer

Most industrial models combine several types of cutting simultaneously. Round and square material is processed. Thin sheets of material undergo 2-sided milling and jointing.

Design specifics

The design of a four-sided woodworking machine includes 3 main parts:

• workpiece feeding device;
• spindle section with cutting elements;
• system for setting operating parameters, adjustment, control.

There are models that have several cutting mechanisms installed sequentially along one side of the part (multiple processing).

The speed of the knife shafts is 5000-6000 per minute. In the machines the latest designs knife shafts make up to 9000 rpm.

Processing area

The basic setup includes 2 horizontal shafts (top/bottom) and 2 vertical spindles. A head with a straight or shaped knife is placed on the spindle. The shaft rotation is in the range of 5000 - 9000 rpm.

The specified dimensions of the product are set by corresponding horizontal movement of the spindle, seating/raising of the cutting edge, and tilting the longitudinal axis at an angle of up to 25°. The thickness of the board is set by moving the upper shaft vertically.

The assembly layout may include the installation of a 5th planing shaft in order to obtain a profile along the bottom plane of the part.

Additionally, ironing knives are designed to eliminate waves on the surface of the wood from rotating heads. A block of fixed blades located at an angle of 45° to the table plane removes 0.02 -0.2 mm of wood with each edge. The wave crests from the jointer are cut to a specified cleanliness.

Control

Reducing human influence in the mechanical process of woodworking increases its functions for accurate measurement, calculation of parameters for software, control of each phase of equipment operation, urgent need to correct deviations.

The control points are:

• calculation of the speed of movement of raw materials to maintain the specified processing accuracy;
• placing each individual node in calculated coordinates;
• synchronization of the complex operation;
• cleaning, removal of generated waste.

IN individual production this requires a significant investment of time. At in-line production gives a significant gain in productivity, quality standardization finished products made of wood.

Specialization

Installations for multilateral wood processing are complex enough in design to make one universal unit. Woodworking shops use varieties that are sufficient to quickly and accurately produce a certain range of products.

Having chosen a four-sided machine for profiling the timber, they produce a profile with a groove-tenon connection, two even (semicircular) sides. The planing operation can be combined on one machine after cutting the profile. The variety of beam cross-section geometry options is determined by the configuration of cutting attachments.

A carpenter using a four-sided longitudinal milling machine simplifies the work of producing wooden beams for door and window frames, baseboards, cabinet parts, and flooring.

Lumber after a circular saw has a poor surface quality. At the same time, a four-sided planing machine with the required performance allows you to achieve the required dimensional accuracy. It has from 4 to 10 spindles, on which, if necessary, a knife with a grooved blade for wood is placed. This makes it possible to operate the equipment as a machine for the production of profiled timber, based on production tasks.

Choice

Technical characteristics, electrical circuit, operating modes, equipment, programming - all this must be studied according to the manufacturer’s declared data. Features of automation operation, requirements for personnel qualifications, raw materials, maintenance must be taken into account when organizing production process, compilation technological maps. Quadruple service availability milling machine, spare parts for it will affect the smooth operation.

Four-sided longitudinal milling machines(milling-moulding, planing or planing-moulding) are designed for processing workpieces on four sides in one pass in order to obtain products of precise geometric shape. Used for the production of molded products, lining, floor boards, imitation timber, tongue and groove, eurolining, parquet, parquet boards, engineered boards, parquet boards, decking boards, planken, double timber, profiled timber, solid timber, laminated timber, planed timber, timber taruka, blockhouse, plinth, platband, including MDF platband.

Recommendations for choosing 4-sided woodworking machines

In order to buy a four-sided machine, you need to decide on the type of product being manufactured. If you want to buy equipment for lining, then the basic four-sided machine is a five-spindle Beaver machine.

The price of the equipment may vary, because the quadrilateral for wood can be four-spindle, five-spindle, six-spindle, seven-spindle and multi-spindle. Depending on the client’s task, the required number of spindles is selected: a 4-spindle machine is suitable for calibrating bars, opening defects, and small carpentry tasks. A 4-spindle lining machine can be used in most cases, but it is better to buy a 5-spindle or 6-spindle quadrilateral.

There are different technologies for the production of lining and other moldings, but a 4-sided machine will be used everywhere. And if the client has a large production volume, it is worth buying a high-speed model, which is in demand in the production of floorboards, linings, blockhouses, imitation timber and must be equipped with a jointer and counter supports and have a feed speed of 60 m/min. Jointer in a four-sided machine – required condition for the production of moldings High Quality. In addition to purchasing the equipment itself, it is necessary to purchase additional mechanization for four-sided woodworking machines or an automatic workpiece feeding system.

The beam machine is a heavy and complex device. Therefore, the Kami Association offers to familiarize yourself with Beaver machines for profiled and laminated timber, which comply with GOST and have a 1-year warranty. Therefore, Beaver and Quadro machines are the best four-sided machine in terms of price-quality ratio.

Buy at a good price

How to choose a 4-sided machine? Specialists from the KAMI association will advise you. They will also help you compare v-hold planing and molding machines and Borovichi for lining and other moldings, which have nothing in common with the famous Beaver brand. If you are interested in models from Winner or Weinig, including used ones, then you can choose any four-sided machine from the Beaver or QUADRO line.

Among the huge amount of woodworking equipment, there are machines that can process parts simultaneously from four sides, and they are called four-sided planing machines. The working element of this equipment is rotating cutters or heads with knives. Since processing occurs simultaneously on four sides, at least four working elements can be installed. Why is it profitable to buy a four-sided wood saw, what is its main difference and what is the price of the equipment? Let's figure it out.

Features of 4 Sided Woodworking Machines

In terms of its functionality, a four-sided woodworking machine can perform several jobs at the same time: jointing, milling, profiling and thicknessing. That is, as you can see, the design of the machine is quite complex, and we’ll talk about this further.

The machines are typically used to create profiled or flat-faced lumber. Feature is that all this work can be done in one pass. These four-sided machines can be used to produce the following wooden products: flooring or parquet boards, laminated or profiled timber, skirting boards, lining, imitation timber and any moldings or window elements. A four-sided woodworking machine is one of the types of longitudinal milling equipment. Therefore, all 4-sided wood devices can be divided into:

• Longitudinal milling.
• Thickness planer.

Thicknesser on wood is used for planing a part to a specified thickness on both sides simultaneously. Quadruple thickness planer initially it is planing and additionally has the ability to profile. This device can perform shallow profiling, with a simple design of a small timber lock.

Longitudinal milling is designed for cutting material along the length to a specified size. This woodworking machine can perform profiling of any complexity. Taking into account the thickness of the wood being planed, the lower shaft of the knife moves in the vertical direction simultaneously with the table top of the device.

Simultaneous processing of wood from four sides significantly reduces time consumption and, accordingly, increases the productivity of any production. It is this difference that makes the four-sided wood saw the optimal equipment in the construction and furniture industries.

Main criteria when choosing a woodworking machine:

• timber feeding system and speed;
• cross-section of lumber for possible processing;
• machine weight;
• processing power;
• equipment price.

All four-sided machines can be classified based on the following characteristics:

• presenting material in different ways.

Design of different components of a four-sided machine

To understand how the equipment works, it is necessary to consider the design features of the machine, which includes a large number of components, the main ones of which we will consider in more detail.

Cast iron bed

At the base of the machine there is cast iron, it may have a different alloy and inserts, but it necessarily absorbs a certain amount of vibration during equipment operation and, due to its large mass, almost reduces it to zero. For feeding timber, the material from which the loading table is made is also important. For more convenient work, there may be auxiliary elements on the table: pressure rollers, a ruler, and so on.

Tools

The number of spindles in a woodworking machine can be set from 4 to 8 or more. All of them, taking into account the model, are installed in different working units with independent electric motors. The spindles are fixed in a cantilever manner. The number of spindles depends on the complexity of the profile, the thickness of the wood removed and the needs during processing of the timber.

In a four-sided longitudinal milling machine there are working rollers, which are divided into: right and left, upper and lower. The main ones in the design are rollers with spindles, which are located below horizontally and on the right vertically. The exact number of planing and shaping elements provided in the equipment determines its power, performance and class.

IN model range From different manufacturers of four-sided machines, there is universal equipment with an element that can replace any of the vertical or horizontal spindles. It can process the product at an angle, that is, it acts as an inclined roller.

At the customer's request, a saw shaft can be installed on some equipment models. This device can cut a wide product to length, which allows you to create material with correct geometric shape and the required section.

Feeder

Pulling, feeding and unloading of products in four-sided woodworking equipment is driven. All work is done using pressure and toothed rubberized rollers. This system can be controlled from a remote control, but the price for these computerized devices is higher.

Control and security system

The protective cover reduces noise during timber processing and also protects the operator from various injuries. The sight glass can be additionally equipped with illumination.

The woodworking four-sided machine is controlled from the panel. Depending on the equipment model, you can perform several actions from the control panel: feed speed products to tools, setting the dimensions of the processed timber, setting the position of the spindles relative to the diameter and part of the nozzle (if the equipment is fully automatic), turning it on and off.

The type of equipment depends on the presence of a hydraulic spindle and joyter in the kit and the number of working tools. These devices sharpen knives directly during processing of the product.

Price of woodworking machines

You can purchase a four-sided longitudinal milling machine for wood in specialized construction stores. But the most profitable option would be to buy the machine directly from the manufacturer. Naturally, this applies only to domestic units; purchasing foreign ones (Italian, German, Chinese, Thailand, etc.) directly is more expensive, because the price of its transportation will cost more than the cost of the equipment itself. In large cities, for example, St. Petersburg, Moscow, Nizhny Novgorod or Kazan, it is possible to rent equipment from industrial companies or in installments directly from the manufacturer.

Basic moments The things you need to pay attention to before purchasing equipment are:

• Reliability of operation.
• Accuracy.
• Availability of service.
• Performance.
• Equipment price.

If a woodworking four-sided machine is planned as an addition to an already operating line, then the size of the equipment must also be taken into account.

The price of a four-sided woodworking machine depends on the following factors:

• functionality;
• Class;
• remoteness of the manufacturer;
• manufacturing plant.

It is important to consider when purchasing technical specifications, especially the combination of different processing options, operating speed and weight of equipment.

Any electrical equipment is a machine that over time can break and wear out. Therefore, when purchasing, it is advisable to select the most durable and wear-resistant machine. This way you will have to pay less often service maintenance, and there will be much less interruptions in work. And the profitability of the work will directly depend on this.

Today, entrepreneurs prioritize not only profit, but also the safety of employees. Therefore, it is important that the equipment has a metal protective casing with sound insulation, limit switches, electric brakes, etc.

Processing of products on equipment must be of the highest quality and precision. To do this, it is important that the device has statistical and dynamic balancing all fixations of parts: rotating spindles and tools.

There are companies that have just begun to take their place in the domestic market, because their price for this equipment is lower, and the quality is at the proper level. For example, these companies include the German brand beaver. To reduce the cost of its products, the company located production in China and Taiwan, but parts for assembly are made in Germany. Buying a little-known brand made in Taiwan or China is practically a lottery. Moreover, it will be very difficult to find spare parts for this model. Therefore, cheap models do not even need to be considered.
