Problems solved by technology
Although this structure solves the influence of the error of the cutting tool on the performance of the cutting tool to a certain extent, when the cutting tool bears a large load, the elastic deformation of the blade increases, and the side of the blade is inclined outward relative to the groove, resulting in the The side positioning surface of the body and the blade is separated, the clamping force can only be provided by the fastener, and the fastener must have a large deformation, which will cause a large vibration or even collapse of the blade

The invention discloses a cutter resistant to vibration. A cutter body, a blade and a fastener are included; the cutter body is provided with at least one set of scrap containing groove and a cutter groove; the cutter body is used for fixing the blade in the cutter groove through the fastener; the cutter groove is composed of cutter groove side faces and a cutter groove bottom face; the cutter groove side faces are provided with concave sawteeth, and the side faces are provided with convex sawteeth; the convex sawteeth are correspondingly placed in the corresponding concave sawteeth; and the cutter body and the blade are composed of the following components, by weight part, 15-18 parts of C, 7-8 parts of Mn, 1-2 parts of Si, 1-2.5 parts of Ni, 3-5 parts of Ti, 5-9 parts of rare earth, 2-5parts of N and the balance Fe and inevitable impurities. The cutter resistant to vibration is simple in stable and capable of effectively inhibiting vibration and improving the impacting resisting capacity.
Description
technical field [0001] The invention relates to a cutting tool, in particular to a vibration-resistant cutting tool. Background technique [0002] Cutting tools are generally connected by means of planar contact between the cutter body and the side of the insert. The tool body and blade of this tool are easy to manufacture and easy to process; at the same time, when the side surface precision of the tool body and blade is high, the effective contact area can be increased, the transmitted torque can be improved, the impact resistance of the blade can be strengthened, and the dimensional accuracy of the cutting tool can be guaranteed. ;The large-area contact between the cutter body and the positioning surface of the blade can make the positioning surface of the blade only slightly deformed when the blade bears a large load, effectively ensuring the consistency of the dimensional accuracy of the cutting tool in the static state and during processing, and improving the cutting t...
