Milling – an effective high-precision method of processing a tree
Wood is widely used in all spheres of our life: from large-scale construction and production of furniture, to the manufacture of small crafts and souvenirs in craft shops. Wood is the first material that a person has learned to apply to improve the quality of his life, yet his popularity has not diminished until now. In addition to attractive appearance, wooden products have strength, durability, practicality and, importantly, safety for health.
Milling – a universal way of processing wood, allowing you to work with billets of all sizes and shapes. Using this technology, they produce joinery, interior items, three-dimensional decorative elements, as well as small souvenirs and children’s toys.
Features of milling of wood materials
The tree is well machinable, but natural wood is characterized by a heterogeneous structure, a different direction of fibers in the layers, and each rock differs in its hardness and density. In addition, raw materials for useful things in everyday life can be not only an array of wood, but wood-based board materials. The technology of milling each of them has features, so the processing mode and cutting tool is selected individually depending on the material properties and the thickness of the workpiece.
Thus, MDF, which is a pressed fine-dispersed shavings, has an average density and a homogeneous structure. These properties of the material allow the performance of artistic milling, the production of three-dimensional elements (letters, images, signs, decorative grilles …)
Particleboard also consists of wood residues, but a larger fraction, glued together with synthetic resins. The material is loose, contains large inclusions of chips, which negatively affects the quality of the edges. Therefore, it is impossible to perform fine milling operations, the use of the router is limited to straight and figured cutting.
Plywood has a layered structure, in which for strength each layer of veneer has a different direction of fibers. Given this feature when selecting the processing mode, you can easily carry out various operations – to make patterns, perform complex cutting, including openwork, to decorate the surface with engraving.
Some nuances of technology
Milling takes place in several stages. First, roughing (one or several passes) is performed, at which a significant layer of material is removed. The final stage (finishing) is necessary to give the surface to be treated with the necessary cleanliness. Solid wood in the first stage can be milled at higher speeds, and for finishing, use a moderate mode and special cutters. Soft rocks are not processed in high-speed mode. If you correctly use the structure, take into account the processing features along or across the fibers, you can achieve an excellent result when performing even fine artwork.
What can be made by milling
Advantages of milling are a huge range of operations, high speed and accuracy of work. In addition, this technology ensures high quality of finished products – compliance with sizes and proportions, clear cutting lines, absence of deposits, chips and other defects. Technological possibilities of milling are not limited to straight or figured cutting. Mills are used for cutting depressions, seats, holes, edge processing. On the milling equipment it is possible to produce shaped products, carrying out relief or sculptural carving, applying patterns, ornaments, and inscriptions on the surface of the workpiece.
All these possibilities of milling are widely used in construction, furniture production, carpentry, in the manufacture of advertising structures, volumetric decor elements for exterior and interior design. Using CNC machines allows you to perform with a high degree of detail workpieces of any complexity, including 3d parts.
