IMPROVING THE QUALITY AND REDUCING THE ENERGY INTENSITY OF SHARPENING FLAT WOOD-CUTTING KNIVES

The quality of sharpening of flat wood-cutting knives in a certain way affects the quality of the parts obtained. The sharpening process is carried out by a grinding carriage performing a rectilinear reciprocating motion relative to a fixed knife. When the massive carriage is reversed, free oscillations (transients) occur, which

leads to a violation of the straightness of the cutting edge of the knife, limited by the requirements of GOST. Reducing the vibration activity of the process and achieving the required quality of knife sharpening provides a constructive solution for reversing the movement, in which the reverse is performed by a lightweight node-a base table with a knife fixed to it, and a massive sharpening carriage is stationary.
