Four-sided machines for wood. Specifications of four-sided woodworking machine Homemade four-sided machine translate into English

Multi-spindle machines are very effective for saving time when processing wood in large volumes.

Wooden blanks, after sawing, have defects, such as surface unevenness, cracks, etc., which must be eliminated before proceeding with their further processing.
To eliminate these defects, milling machines are used, by means of which each of the four surfaces of the workpiece is processed separately.
When the volume of processed wood is large enough, it is easier, more convenient and more economical to use multi-spindle woodworking machines.
Such machines are also called. As the name suggests, all four planes of the workpiece are machined, or gouged, at the same time.

It can have from 4 to 10 spindles, depending on the requirements for the final form of your product. Simply put, the number of spindles depends on the complexity of the profile of the product that you want to get at the output of the machine.

consists of the following main parts:

The feeding table has clamping elements and the ability to adjust the frame vertically, which allows you to pass workpieces of various thicknesses through the machine.

For example, in order to make a heavily deformed surface smooth, it is necessary to remove a large amount of wood, on the other hand, direct wood harvesting requires the removal of a very small layer of material (it is enough to remove only traces of a band saw).

In a situation where it is necessary to straighten a piece of wood entering the machine, a pressure roller is used in front of the first upper spindle. An additional clamping block located in front of the first lower spindle is used for thin material that does not need to be dressed. This option can be disabled via the machine control panel.

At the initial stage of passing the material through it is very important to achieve the smoothness of the bottom and right sides of the workpiece, which are the base for further operations to give the desired shape to your product.

Another method of wood straightening, the use of a fluted table, is the most suitable for processing hardwoods. In this case, the first lower cutting unit forms grooves on the underside of the workpiece, shaped like a grooved table, which reduces friction between the workpiece and the tabletop and evenly feeds the material for further processing.

But this method of wood straightening requires that the four-sided machine has another lower spindle, the cutting block of which will remove the intermediate grooves and level the bottom surface of the product. The worktable can be equipped with a manual or automatic feed system for waxilite, a resin-dissolving lubricant, to facilitate workpiece feeding. In the case of processing resinous wood species, an additional lower spindle is also necessary to remove waxilite from the underside of the workpiece.

Feed rollers of a four-sided planer

The feed rollers can be equipped with spring or pneumatic cylinders. Rollers must be properly designed to provide maximum traction and minimum wear.
Vertical spindles of a four-sided planer:
For vertical spindles, a high-quality and flexible tuning system is required, otherwise it will take a lot of time to change the type of profile and, accordingly, the diameter of the tool.

The quick adjustment of the vertical spindles allows optimum contact between workpiece and work table.
When the vertical spindles of a four-sided planer are in a fixed position, the diameter and working height of the cutting tool, as well as the feed speed and pressure of the feed rollers, are adjusted simultaneously through the digital control system panel. High-quality adjustment of the left vertical spindle guarantees high quality gouging, and is especially relevant when working with hardwoods.

Top Spindle Quadruple Planer

The top spindle is the first right vertical spindle of the machine. The cutting tool located at the top position can be used both for planing the surface and for profiling the workpiece. A good four-sided machine should give up to 40 mm of profiling on the upper horizontal/vertical spindle.

Universal Spindle Quadruple Planer

The planer can be equipped with an optional universal spindle to achieve greater profiling flexibility.

Quadruple planer options

The four-sided planer can be equipped with additional optional devices, such as: additional feed device after the upper horizontal spindle, corrugated hardwood work table, extended feed and work tables, increased power of spindle motors and others.

One of the main indicators of modern woodworking production is the quality of work, as well as productivity. To fulfill these conditions, appropriate equipment is required. One of them is a four-sided woodworking machine.

Design and types of machines with multiple processing

Such production centers appeared relatively recently. The specificity of their design lies in the fact that they combine several operations. In this case, the processing of wooden products occurs immediately from four sides.

Most often, with the help of this equipment, jointing or milling operations are performed. Structurally, the model consists of a part feed unit, a spindle section and a control system for equipment parameters. Moreover, there can be several processing heads on one side. This approach to layout allows you to optimize the time to complete the operation, as well as reduce the cost of the final product.

The four-sided machine can perform the following types of operations:

• jointing and planing. You can do it with the help of shafts on which blades of a certain configuration are installed. Due to the design of the machine, roughing and finishing can be performed simultaneously;
• milling. Instead of planer shafts, disc cutters are installed on the working heads. In this case, it is possible to do only longitudinal milling. For processing with finger cutters, it is necessary to periodically stop the part, which is not provided for by the design.

Most models of four-sided woodworking machines can combine these two functions. It is important to determine the mechanism for configuring processing blocks, as well as their impact on performance.

With the help of milling units, it is possible to perform operations on the longitudinal cutting of wooden parts. To do this, the design must provide mechanisms for fixing the formed blanks.

Advantages and disadvantages of equipment

One of the undoubted positive qualities of the operation of four-sided woodworking machines is high performance. To achieve optimal results, a numerical control unit must be present in the design.

In this case, the influence of the human factor will be minimal. It is obligatory to fulfill the conditions for the correct compilation of the program, as well as the accurate measurement of the workpiece being processed. The four-sided machine in the optimal configuration is designed for processing square (rectangular) timber or cylindrical blanks. Milling or jointing of sheet materials can be carried out on a maximum of two sides.

The following factors can be attributed to the features of the operation of equipment of this type:

• preliminary calculation of the speed of movement of the workpiece along the frame. This is necessary to ensure maximum processing accuracy;
• adjustment of each individual milling or jointing unit, as well as the consistency of their functioning with each other;
• timely removal of production waste from the processing area.

The main disadvantage of four-sided woodworking machines is their high cost, as well as the complexity of setup. But in terms of production lines, these indicators are not significant.

To automate the work process, the installation must be equipped with an automatic feed line for workpieces. Additionally, this block can perform the function of positioning the part relative to the machining tools.

Since a four-sided machine for complex woodworking belongs to the category of expensive equipment, it is necessary to take into account all the nuances of the design and technical characteristics for selection.

First of all, it is determined by the performance of the equipment. This indicator depends on the feed rate of the workpiece, its dimensions and the degree of processing. It is also necessary to take into account the weight and dimensions of the wooden part.

When choosing the optimal model of a four-sided woodworking machine, you need to pay attention to the following factors:

• machine design requirements. It must withstand maximum loads, since this type of equipment is often designed to process massive products. The best option is the material of manufacture of cast iron alloy;
• feed system. It is a set of shafts, the surface of which has a corrugated shape. To minimize the appearance of defects, the elements of the system must be rubberized;
• the complexity of setting up the processing unit. Best of all, models that have a CNC cope with this task. Setting of cutters or planer knives is carried out automatically after entering the delivered program;
• the accuracy of the operation.

These parameters should be considered when choosing a four-sided woodworking machine. For the exact position of the workpiece relative to the machining centers, a system of sensors must be provided in the design.

In addition, when analyzing the equipment model, it is necessary to take into account the remoteness of the manufacturer's service centers, the cost of components, as well as the terms of the warranty.

During the operation of the equipment, you should follow the rules specified in the proposed instructions. In no case can workpieces of larger dimensions be processed than stipulated by the rules. It is mandatory to perform preventive and repair work to maintain the normal condition of the equipment.

It is also important to correctly set up the machine. Not only its weight and dimensions are taken into account, but also the dimensions of wooden blanks. The operator should have no difficulty in feeding material for processing.

For example, you can see the work of a professional model of a four-sided woodworking machine:

Four-sided woodworking machines allow quite high-quality jointing of workpieces. The most commonly processed boards. There are different types of modifications on the market. First of all, the separation of devices is carried out according to the position of the caliper.

Also, machines come with two or three guides. Racks they can be wooden or metal. In order to learn more about machines of this type, specific modifications should be considered.

3 kW modification

The 3 kW machine is quite easy to assemble. In this case, the engine is taken as a collector type. However, before installing it, it is important to assemble the bed. Some experts recommend using metal supports, however, are more reliable.

After fixing the frame, it is necessary to proceed with the assembly of the caliper. For this, a steady rest with a rotating flywheel is selected. The cutter in this case must be used of small length. After fixing the caliper, the lunette is attached. In order for the workpiece to be securely fixed, a plate is installed. At the end of the work, it remains only to put the control unit to start the collector engine.

Assembly of the model for 5 kW

Four-sided woodworking machines for 5 kW must be made with rigid beds. To do this, the width of the stop must be at least 2.2 cm. In this case, the plate is used with a small width. However, the bed is installed with additional support. Flywheels are used to adjust the caliper.

There are also modifications with roller devices. However, making them yourself is quite difficult. In this case, it is more appropriate to use a drive shaft. The engine must be installed at the bottom of the structure. You should also provide a place for the control unit. To protect the caliper, experts recommend using casings. If desired, you can make a shield. The cutter is installed on the machine last.

10 kW devices

Woodworking machines four-sided 10 watts are common. In order to assemble the device, it is necessary to make a frame for four supports. It is also important to choose a wide plate for the rack. In this case, it is more expedient to install the caliper over the stops. To fix the rack you need to use

Many experts also recommend using screws to improve grip. The guides in the device are attached behind the caliper. Ultimately, it should not touch the center plate. Guides can always be trimmed if necessary. To fix the protective shield, you will have to use a welding machine. It is more expedient to select CNC. They are quite expensive. At the end of the work, it remains only to fix the cutter.

Upper caliper device

To make a quadrilateral, you must first deal with the rack. In this case, the legs can be made from metal profiles. Many experts recommend against using steel sheets. Directly the working plate is selected from cast iron. In order to fix the rack, a metal corner should be welded. It should be located at the edge of the bed.

In this case, it is important to calculate the distance to the cutter. The protective plate is installed last. To secure the caliper, many recommend attaching additional screws. The flange must be away from the caliper. After fixing the steady rest, flywheels are installed. They are needed to set up the cutter. At the end of the work, the motor is put together with the control unit.

Bottom caliper model

A home-made four-sided woodworking machine with a lower caliper has large dimensions. However, such models allow you to process long boards. In this case, motors are installed of an asynchronous type with a power of 5 kW or more. CNC blocks are used to control the processing process. Racks in devices are often made of steel angles. Modifications are rare. In order to make a model yourself, you need to choose a high-quality plate.

Many experts recommend choosing a small length. It should weigh no more than 15 kg. Then there will be no strong pressure on the racks. The caliper in this case is installed next to the pin. Directly guides are mounted in a horizontal position. In order for the cutter not to rub against the work area, a steady rest is used. In many modifications, it is used cam type.

Modification on a movable plate

It is quite difficult to make four-sided woodworking machines with movable plates on your own. In this case, a roller mechanism is selected that is able to withstand a large load. The bed must be made at least 30 cm wide.

Side supports can be fixed on metal corners. In order for the roller mechanism to be stationary, a pulley is used. In this case, the caliper must be installed after the motor. CNC devices are very rare. The most commonly used conventional control units. Directly the lunette is used cam type. After fixing it, a cutter is installed.

Model with two quills

The model with two quills allows you to process boards of large widths. To make a four-sided woodworking machine (photo shown below) with your own hands, you need a long plate. In this case, it is more expedient to make racks from metal corners. Metal corners are also used to fix the plate. The caliper must be installed above the quill.

Flywheels in this case will be on the sides of the bed. Before installing the motor, a steady rest is attached. Screws are used to fix it. Legs are usually made of metal corners. Many motor experts advise using a collector type. Its rated power must be at least 5 kW. The control unit is standard installed contact type.

Machines on two guides

It is quite easy to assemble machines on two guides. The support in this case can be installed under the work plate. The motor is allowed to use small power. It is more expedient to select a lunette with a through drive. The flywheels are directly mounted on the side of the steady rest. Many experts advise soldering the work plate to the frame. In this case, the cutter is adjusted with screws. The motor must be installed from the side of the caliper. The control unit can be used with CNC.

Model SCH-1

The four-sided woodworking machine SCH-1 is very popular. In this case, the guides are installed near the steady rest. The bed has a small height. Flywheels are located on the caliper side. If we talk about the parameters, then the motor is used at 5.5 watts. The limiting frequency of the model is 55 Hz. In a minute, the cutter is capable of making more than 2 thousand revolutions. The quill of the model is provided with

Handwheels are used to adjust the cutter. The stand in the device is set to 45 cm. The carrier plate of the model is used without stops. Directly the control unit is located next to the motor. There is a lining under the lunette. A holder is used to fix the workpiece. These four-sided woodworking machines (Borovichi, Russia) stand on the market in the region of 230 thousand rubles.

A four-sided woodworking machine is a specialized equipment that is used for profiling natural timber. Its samples are indispensable machines in woodworking enterprises, they are also currently used in the furniture and construction industries.

It is with their help that today they produce some types of parquet, as well as moldings, door furniture. Let's look at the four-sided machine in more detail.

1 Technical features of the equipment

The four-sided woodworking machine works on the principle of a milling machine. The clamping chuck feeds the necessary element for processing into the four-sided machine, which is then finished on four sides with special milling cutters and protrudes back with perfectly smooth surfaces.

1.1 How to choose a machine for yourself?

When buying a 4-sided milling machine from options 4015, 26, 13, 160, 15, 51 and others, you need to pay attention to such design aspects:

1. Power. Here, to be guided by the rule, the higher the better, it is not necessary. Some models may have low power, but the quality of processing makes this indispensable at home. But samples with a high given parameter should be considered mainly as professional equipment.
2. The type of CNC provided by the SFC. The best option for today is eta. But if this type of CNC is not convenient for you personally, you can choose an alternative option. Fortunately, PFS produces four-roll models of various types of CNC.
3. The structure of the bed. It is desirable that the four-roll samples have a solid element. This improves the quality of their balancing and overall reliability.
4. The cost and quality of components. Remember, you will have to change knives from time to time, like other consumable items. It is desirable that they be affordable for you.

Also, in all models, regardless of PFS and CNC type, you need to pay attention to functionality. The general advice here is don't go for very complex versions. Often, four-roll models with a minimal but well-established set of options perform better.

Especially at the moment, attention should be paid to those who take the product for home use.

2 Popular Four Sided Roll Forming Machine Models

Today, the four-sided planer is on the market in a large number of designs from various PPS. The most popular among them, worthy of your attention, are the following models:

• four-sided machine sch 1 milling. One of the most popular types for the production of profiling timber. Does not require special installation conditions, has a simple CNC, reliable chuck. For one supply of material can remove up to 5 mm from the bar. Designed for processing parts with a length of 1 meter;
• model s26 2H. Another option for processing the profiling beam, thanks to the efforts of PFS, has a universal chuck. C26 2H makes it possible to work with samples from 63 cm. C 26 has an average power, thanks to which it can be used for homework, and for large furniture production. Like other roll forming patterns 26 or 13, extremely easy to use;
• four-sided milling machine s20 4b - a model of turning equipment designed for processing both coniferous and deciduous trees. Like the c26, 13, 15 model, it has a fairly high processing speed, a universal cartridge, which is why it can also be used in woodworking enterprises. And like c26 2H, it guarantees high quality output, regardless of the processing parameters set;

• version c16 1a. A type of turning equipment for home and factory woodworking. The advantages of this option include the maximum ease in managing the sample c16 1a, its reliability, as well as a wide enough range of applications, which provides a universal cartridge, as in models 26, 13, 160, 15. The maximum volume of the workpiece for it will be 160 x 80 mm. C16 1a it will be especially convenient for beginners;
• Hold MB 4015 is one of the most reliable models of equipment with a solid frame. Designed milling Hold for workshop processing;
• Beaver 520 is one of the most modern versions of equipment. Has, like Hold, quality software. Compact yet powerful enough. Recommended for industrial use.

2.2 Do-it-yourself four-sided machine

Of course, for many private households who want to start producing lumber, a four-sided machine, for example, Hold MB 4015, c 26, c16, 13 and other models, from the manufacturer is a rather expensive purchase.

The question arises - is it possible to make such equipment with your own hands. There really is such a possibility. In order to make a homemade milling machine, you need to purchase a set of cutters (here it is advisable not to save, since the level of wood processing by a ready-made structure depends on the quality of these components).

Next, you will need to assemble the body, the supply line of the type that is installed on the factory models. You can even make a cartridge from a regular profile. Structurally, the cartridge in home and factory models, including 4015, 26, 13, 160, 15, 51, does not differ.

It is also better to take the engine ready, and not to do it yourself. You can purchase a unit of the required power from similar equipment, replace flexible parts and gears on it, and install it for work. Next, you will need to make a homemade control unit, taking into account the number of operating modes.

If you are taking on this case for the first time, stop at a simple scheme, which will only turn on and off.

You can assemble a home-made milling machine according to the general scheme for such products, for example, used in versions 4015, 26, 13, 160, 15, 51. At the end of the work, you must make sure that the fasteners are secure, especially the cutters themselves.

Only after you make sure that the home-made analogue of factory equipment is working properly, you can start processing wood with it.

Don't forget about safety rules. Those who choose a homemade option, they need to pay special attention.
