Woodworking machinery processing process four big characteristics
Woodworking machinery processing object - Wood, a special non-metallic materials is a god of nature. Wood is made up of wood fiber, pectin, etc, between strong cohesive force, also contain moisture, such as wood section. Wood is a kind of heterogeneous structure material, therefore in the process of machining showed many complicated mechanical and physical and chemical now, such as elastic deformation, bending, compression, crack, burr, etc. In addition, the hardness of wood is not high, Except a few) , has the good separability, wood processing can't exceed its carbonization temperature, About 100 - 120℃) 。 All these factors, constitutes the woodworking machinery compared with metal cutting machine tool processing, have different characteristics. The specific performance the following: 1. Woodworking machinery in machining, the tool when the workpiece cutting speed is higher, big vibration and big noise. 2. In processing manual than major, in the process of labor intensity. 3. Woodworking machinery manufacturing precision is low. 4. Woodworking machinery knife shaft speed is high, the inertia big, brake trapped.
