Lumber machine: high-quality processing of timber - the key

The processing of timber is an important work, it will depend on its quality in many respects how much the product will serve you. There is a wide range of woodworking products on the market of construction equipment, you can purchase a lumber machine for tonnier and for thicker blanks - it all depends on your needs.

In this article we will talk about such equipment, its advantages and how to get it.

Design features

For more detailed acquaintance we suggest you to consider the quadrilateral machine for a bar the Leader 4 * 240. This model belongs to the heavy class of machines, and its frame is made of square pipes of large cross-section. This is done to ensure maximum rigidity of the structure. The frame design of this equipment gives a full guarantee of the absence of vibration.

During the work on the machine preparation is processed from all directions for one pass. It is served from the end using a special arrow-shaped pusher, the speed of its movement is controlled by the operator. Throughout the cycle, it is in contact with the wooden workpiece. After the processing, it returns to its original position (10-15 seconds after the start). (See also the article cut timber and its role in civil construction)

Side rollers, clamping upper rollers and guide bar ensure the stability of the position of the workpiece during processing. The cross section of manufactured products depends on the installed tool.

Important. Chip removal is due to a special socket, which is provided on the machining spindle.

Features and benefits

1. The main advantage is the extremely reliable feeding of wooden workpieces. During processing, the pusher on the carriage moves the timber through all the spindles and thus provides the same force and feed rate. This quality of feed cannot be obtained using ryabuh and rollers. Working on this equipment, we get a high and stable surface quality of the treated timber along the entire length. It will not interfere with crooked or frozen timber, because there is not much difference for the pusher;
2. Thanks to such a pusher, the logging machine has the so-called protection against "fool". The pushing carriage gets effort thanks to a rigidly mounted rail on the feed table, as well as a drive sprocket.

The latter is pressed by the spring to the chain and, with a small rolling resistance, it disengages (turns) with the chain. Such a constructive solution saves the machine from careless handling;

1. This machine for the manufacture of timber has an adjustable position of all work items: rollers, rollers, table surface and spindles. If necessary, you can at any time adjust the location of these elements for high-quality and comfortable processing;
2. The frame structure, in addition to the required rigidity, also provides convenient and quick access to the components of the equipment; therefore, replacement of individual parts, maintenance and adjustment are simple and do not require much time;
3. The feed rate is adjustable and allows you to select the necessary modes of operation based on such conditions: the hardness of the material, the depth of the shooting, the size of the cross section, etc.

Machine selection

The machine for the production of timber has some parameters that you need to focus on when buying:

• The largest cross-section of the bore. For construction needs need from 30 * 40 to 20 * 20 cm;
• Manufacturer. One brand can be very different from another, therefore, in the selection process, you need to focus on feedback from the owners of such equipment;
• View of the bed. It can be of two types: welded and cast. Experts advise to purchase equipment with a cast bed. What are the differences between these types you ask. Welded less reliable and has less weight, and the cast has more weight and is not subjected to corrosion processes. In general, machines with a cast bed more reliable and quality;
• Spindle mounting section. In the considered machine, it varies from 3 to 5 cm. The higher this number, the less load the bearings and the spindle shaft receive. In addition, the larger the spindle's mounting section will be, the greater will be the possibility of choosing a planer head (material of manufacture);
• With counter support or cantilever type. The difference is that the cantilever type lumbering machine has one point of support for the spindle shaft, and two with counter-supports. In the first type, blanks with dimensions of up to 23 * 23 cm with a length of up to eight meters and low humidity can be processed, and on machines of the second type it is possible to work with dry and wet materials; (see also the article Dry planed timber - scope)

• The number of spindles. It is best to take the equipment with the number of spindles from six pieces for machining a timber. Due to this choice, the load will be redistributed between the engines, thereby increasing their lifespan. In addition to load sharing, there is an improvement in processing quality;
• Feed rate This component plays a big role when buying a machine, and the price will depend on it. We strongly advise you to purchase machines at a speed of more than ten meters per minute, as the quality of work is noticeably reduced.

Important. With a great desire, you can make a logging machine with your own hands. This will require materials, desire and working drawings, which are freely available on our portal.

Results

A lumbering machine is a useful tool not only for professional carpenters, but also for ordinary home craftsmen. Thanks to him, it is possible to significantly improve the quality of the work produced, as well as reduce the time spent on them. (See also the article How to use unplaned timber)
