Woodworking machinery CNC lathe processing material what are dry processing methods

Woodworking CNC lathe in machining after or before processing to the processing of materials to do some dry processing craft, so made products can accord with the requirement of consumers, the processing of products is also can be used longer. So for the material drying technology we is necessary so the processing method which have some of it. Wood drying means mandatory for wood with natural and artificial method of evaporation from water, make the moisture content of lumber moisture content down to conform to the requirements of the use, avoid the wet material in the process of storage, transportation of hyphal corrosion and reduce in the process of using numerical control woodworking lathe processing wood splitting, deformation phenomenon, advances the quality of wood products to lengthen service life. Wood is a kind of natural drying method using gas convection drying. Artificial convection heating and drying methods are so important in the dielectric heating, the former has a dry kiln, solar drying, drying too dry and water liquid centrifugal force; The latter has a microwave drying, high frequency drying. And infrared radiation heating drying and belong to contact heating drying. At present both at home and abroad is given priority to with convection heating air drying and kiln dried, especially dry kiln as the major method. Wood drying is first wood surface evaporation, the moisture content of surface layer is lower than the wood interior, internal moisture move to the surface under the effect of moisture content gradient. At the early stage of the drying speed depends on the speed of wood surface evaporation, the middle and late drying, drying speed depends on the internal moisture movement speed, is inversely proportional to the plate thickness and wood specific gravity. In addition, sapwood drying speed is faster than heartwood. The strings of the hard wood panel dry faster than diameter panel; But softwood string diameter surface is not very significant difference. Tree species for drying effect, easy dry wood have Korean pine, scales spruce, fir, pine, fir, red one spruce, masson pine, fir, mongolica, basswood, paulownia, polishing the wood; Not easy to dry wood have cypress wood, color wood, maple wood, yellow pineapple, walnuts, camphor, catalpa wood, Chinese catalpa, elm katus, persimmon, liquidambar, etc; Difficult to dry wood are larch, manchurian ash, beech, cyclobalanopsis, German oak, lotus, cocobolo wood, oak, oak, etc. Above is to dry the woodworking CNC lathe materials used in some of the ways to step in and some basic knowledge of material drying is necessary step for the use of woodworking CNC lathe will have certain influence, also has a great influence for processing the finished product.
