FIELD: process engineering.
SUBSTANCE: invention relates to grinding and may be used for sharpening of saw chains. The chain and sharpening disc are relatively positioned to set the tooth sharpening angle in plan, tooth cutting angle and sharpening direction angle. The latter is produced by sharpening of saw chain LH and RH teeth by different zones of sharpening disc spaced apart in the circle arc to make the angle equal to twice the sharpening direction angle. Chord connecting said different disc zones is located behind the tooth blade parallel with the chain lengthwise plane. Claimed chain sharpening device provide for high efficiency of sharpening and longer life thanks to ruled out damage of the chain drive link.
EFFECT: higher efficiency of the process.
