The article is devoted to the improvement of circular saw machines with pneumatic drive of cutting mechanism. Currently, circular saws are widely used for producing of sawn timber because they have high productivity. The drive of saw blades more often is carried out by electric motors through additional transmission (gear, belt, etc.). In the recent literature are offered technical solutions, in which as a drive of circular saws provided by using of pneumatic. Energy source interacts with the circular saw will all...

One of the main factors influencing the accuracy of the obtained lumber is the rigidity and stability of saws. In the process of sawing woodcutting tools heated. This phenomenon can cause a loss of rigidity and stability of saws. A log frames and band saws negative influence of heating can be compensated the additional tension and setting directing. Particular importance is the heating of circular saws due to the appearance of a temperature gradient along the radius in the process of sawing wood. Upon reaching the...
