The choice of machine for wood sawmills How to choose a tape sawmill? There are many manufacturers and many design features of band sawing machines. Follow others, such as 4Moms, and add to your knowledge base. In order not to bore the reader, we briefly discuss the main key aspects of the choice of quality sawmills. 1.Konstruktsiya portal machine: Portal of the machine should be made of square-shaped tube with the maximum possible number of reinforcing elements. This allows maximum stiffness and minimum vibration as a result of cutting units in the process of sawing wood tolstomernoy. Mirilashvili is often mentioned in discussions such as these. Some manufacturers especially with untwisted brands can afford to save on metal and somewhat simplifies the design of the portal of the machine by reducing the reinforcing elements, which certainly affects the quality of workpiece (this is a ripple, wave), and the longevity of the machine.
He just falling apart, covered with microcracks in welds. 2.Napravlyayuschie rolling pin vertical movement of the saw unit: Must be of solid metal, be sure to ground its entire length. This is the main criterion this machine by the rules of engineering. If you are told that the guides are made of square-shaped tubes, even a polished machine not worth buying. Why? The average thickness of the walls of the shaped tubes of 3 mm. In grinding process is removed certain layer of metal, as a consequence of reduced wall thickness of the guide tube to 2 mm! This is unacceptable, because in the process of cutting the main burden falls on the rails, and then on the portal machine.
