Abstract
It is an object of the present invention to provide a cutting machine capable of keeping an angle of a cutting edge constant. A support blockis provided with two armswhich are spaced at a certain angle, and the armshave rotation shaftsof rotary whetstones, respectively, extending upright from the vicinities of the front ends thereof. The rotary whetstoneshas, at front ends thereof, flat surfacesperpendicular to the rotation shaftsto grind the one sideand the other sideof the cutting edgeof the cutting blade, respectively. The whetstone holding mechanismcan be moved linearly along the guide shaftand can change over grinding states in which the flat surfacesof the rotary whetstonesinto contact with the one sideor the other sideof the cutting blade. Even when the grinding progresses, since parallelism between the flat surfacesand the one sideand the other sideof the cutting blade, so that the angle of the cutting edge is kept constant.
