The Structural Characteristics of Three sided Milling Cutter with Staggered Teeth in Precision Parts Processing
The structural characteristics of circumferential grooves and cutter teeth in precision parts processing are shown in the figure
The tooth grooves on the circumference are spiral, and have two directions of rotation with staggered intervals. Half of the tooth grooves are right-handed and the other half is left-handed. The teeth of the main cutting edge, the rake face and the rake face with a certain angle are formed by the polygonal tooth back and the tooth space containing the chips. The cutter teeth are also divided into right and left rotation, and the left and right cutter teeth are staggered on the circumference.
The structural characteristics of the end face gear groove and cutter teeth The structural characteristics of the end face gear groove distribution of the staggered three edge milling cutter. Because the circumferential gear groove has left and right rotations, on the same end face, half of them are the end cutting edges with positive rake angle and the other half are the end cutting edges with negative rake angle.
The staggered three side milling cutter retains the end cutting edge with positive rake angle and cancels the end cutting edge with negative rake angle. It is recessed into the two end faces, so as to form the tooth grooves and cutter teeth that are staggered and evenly distributed at both ends of the staggered three side milling cutter. In the process of precision parts processing, the cutting edges at both ends of the cutter have good cutting ability and spacious chip holding grooves.
