Second-hand woodworking machinery processing characteristics of
woodworking machinery processing object & ndash; 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. 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. Woodworking machinery manufacturing precision is low.
3. Woodworking machinery knife shaft speed is high, the inertia big, brake trapped.
4. In processing manual than major, in the process of labor intensity.
second-hand woodworking machinery operation after the safety of the operation requirements
1, the operation of second-hand woodworking machinery, should cut off power supply, check the Lord. Shaft bearing and switch whether fever, such as found switch fever, may be poor contact or loose connection, should reflect the early take measures to relevant personnel.
2, cleaning machinery and equipment, with the pump or broom to clean up the scene, check whether screw, nut loose or fall off.
