Four-sided longitudinal milling machines(milling and molding, planing or planing and molding) are designed to process workpieces from four sides in one pass in order to obtain products with an exact geometric shape. They are used for the production of molded products, lining, floor boards, beam imitation, tongue and groove, eurolining, parquet, parquet board, engineered board, parquet board, terrace board, planken, double beam, profiled beam, massive beam, glued beam, planed beam, beam taruki, blockhouse, plinth, platband, including - platband from MDF.

Recommendations for choosing 4-sided woodworking machines

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

The price of equipment may vary, because the four-sided for wood is 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 sizing the bar, opening defects, small carpentry tasks. A 4 spindle clapboard machine can be used in most cases, but it is better to buy a 5 spindle or 6 spindle quad.

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, lining, blockhouse, 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 the purchase of the equipment itself, it is necessary to purchase mechanization for four-sided woodworking machines or an automatic feeding system for workpieces.

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

Purchase at a bargain price

How to choose a 4-sided machine? The specialists of the association KAMI will prompt. They will also help you compare v-hold moulders and burrs for lining and other moldings, which have nothing to do with the famous Beaver brand. If you are interested in models from Winner or Weinig, including used ones, then you can pick up any four-sided machine from the Beaver or QUADRO line.

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

Features of 4 Sided Woodworking Machines

According to its functionality, the 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 complicated, and we'll talk about this further.

Machine tools are commonly used to create lumber with a profile or a flat surface. Feature is that all this work can be done in one pass. On these four-sided machines, you can produce such wooden products: floor or parquet boards, glued laminated or profiled timber, skirting boards, lining, imitation timber and any molded or window elements. The four-sided woodworking machine is one of the varieties of longitudinal milling equipment. Therefore, all 4-sided devices on the tree can be conditionally divided into:

• Longitudinally milling.
• Thickness planer.

Planer on wood is used for planing a part to a specified thickness simultaneously from two sides. The four-sided thicknesser is initially planer and additionally has the ability to profile. This machine can produce shallow profiling, with a simple design of a small beam lock.

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

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

Main criteria when choosing a woodworking machine:

• system and speed of feed of a bar;
• section of lumber for possible processing;
• machine weight;
• processing power;
• equipment price.

All four-sided machines can be classified according to the following features:

• presenting material in different ways.

The design of various 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 nodes, the main of which we consider in more detail.

Cast iron bed

At the base of the machine is cast iron, it can have a different alloy and inserts, but it necessarily absorbs a certain amount of vibration during the operation of the equipment and, due to its large mass, almost reduces it to zero. For feeding the 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. Fixed spindles cantilever. The number of spindles depends on the complexity of the profile, the thickness of the wood removal and the needs during the processing of the timber.

In the milling four-sided longitudinal 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 horizontally below and vertically on the right. The exact number of planing and tinting elements provided in the equipment depends on its power, performance and class.

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

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

Feeder

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

Control and security system

The protective cover reduces noise during the processing of the cant, and also protects the operator from various injuries. The sight glass can be additionally equipped with lighting.

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

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

The price of woodworking machines

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

Basic moments, which you need to pay attention to before purchasing equipment, these are:

• Reliability of operation.
• Accuracy.
• Availability after-sales service.
• Performance.
• Equipment price.

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

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

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

It is important to consider at the time of purchase technical specifications, especially the combination different options processing, work speed and weight of equipment.

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

Today, entrepreneurs in the first place is 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 the equipment should be of the highest quality and accuracy. For this, it is important that the device has done static and dynamic balancing all fixing parts: rotating spindles and tools.

There are firms that have just begun to take their place in the domestic market, because the price of 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 their products, the company has located production in China and Taiwan, but the parts for assembly are made in Germany. Buying a little-known Taiwanese or Chinese brand is almost like 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.

Perfection technological processes complicates the equipment, increases the productivity of a single unit. In carpentry, a four-sided woodworking machine combined previously separate operations on one table with a single pass of the workpiece. Cleanliness, accuracy of processing meets the established quality standards.

Possible processing methods

Cut off the layer from 4 sides of the blank can be different heads with blades of different profiles:

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

Most of industrial models combines several types of cutting at the same time. Material of round and square section is processed. Thin sheets of material undergo 2-sided milling, jointing.

Design specifics

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

• workpiece feeder;
• section of spindles with cutting bodies;
• system for setting operating parameters, adjustment, control.

There are models that have several cutting mechanisms installed in series on one side of the workpiece (multiple processing).

The number of revolutions of the knife shafts is 5000-6000 per minute. In machines of the latest designs, knife shafts are made up to 9000 rpm.

Processing area

The basic installation includes 2 horizontal shafts (upper/lower) and 2 spindles arranged vertically. A head with a straight or shaped knife is placed on the spindle. The rotation of the shaft is in the range of 5000 - 9000 rpm.

The given dimension of the product is set by the corresponding movement of the spindle horizontally, landing / lifting cutting edge, tilting the longitudinal axis at an angle of up to 25°. The thickness of the board is set by shifting the upper shaft vertically.

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

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

Control

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

Checkpoints are:

• calculation of the speed of movement of raw materials to comply with the specified accuracy of processing;
• setting each individual node in the calculated coordinates;
• synchronization of the complex;
• cleaning, disposal of generated waste.

In individual production, this requires a significant investment of time. In mass production, it gives a significant gain in productivity, quality standardization finished products from wood.

Specialization

Installations for multilateral wood processing are complex enough in design to make one universal unit. In woodworking shops, varieties are used that are enough to be able to quickly and accurately produce a certain range of products.

Having chosen a four-sided machine for profiling a beam, a profile is produced with a groove-thorn connection, two even (semicircular) sides. Planing operation can be combined on one machine after profile cutting. A variety of options for the geometry of the beam section is determined by the configuration of the cutting nozzles.

A carpenter using a four-sided longitudinal milling machine simplifies the work of obtaining wooden beams for door, window frames, skirting boards, cabinet details, flooring

The lumber after the circular saw has a poor surface quality. At the same time, a four-sided planer with the required productivity can achieve the required dimensional accuracy. It has from 4 to 10 spindles, on which, if necessary, a knife with a slotted blade for wood is placed. This makes it possible to operate the equipment, like a machine for the production of profiled timber, based on production tasks.

Choice

Specifications, wiring diagram, operating modes, equipment, programming - all this must be studied according to the manufacturer's declared data. Features of the operation of automation, requirements for the qualification of personnel, raw materials, maintenance must be taken into account when organizing production process, drafting technological maps. Availability of four-way service milling machine, spare parts to it, will affect the smooth operation.
