Problems solved by technology
[0007] Aiming at the deficiencies of the prior art, the present invention provides a double-sided groove-type indexable cutting insert for finishing, which solves the problem that after a long time of workpiece cutting, the four or three cutting edges on the surface will be worn and damaged. It is necessary to replace the cutting blade as a whole, resulting in high material cost and a waste of material

A mounting mechanism comprises a connecting block, the right surface of the connecting block is rotationally sleeved with a pin column, the left surface of the connecting block is sleeved with a bolt in a threaded mode, the cutting blade comprises a cutting blade body, a groove is fixedly formed in the bottom of the cutting blade body, and a through hole is fixedly formed in an inner cavity of the cutting blade body. Sliding blocks are symmetrically and fixedly connected to the surface of the cutting blade, the limiting mechanism comprises a sleeve, a first spring is fixedly connected between the bottom of a telescopic rod and an inner cavity of the sleeve, trapezoidal blocks are symmetrically and fixedly connected to the surface of the telescopic rod, and sliding grooves are symmetrically and fixedly formed in the opposite faces of an extrusion plate. According to the double-sided groove type indexable cutting blade for finish machining, the problems that after a workpiece is cut for a long time, four or three cutting edges on the surface of the workpiece can be abraded and damaged, the whole cutting blade needs to be replaced, the material cost is high, and more materials are wasted are solved.
Description
technical field [0001] The invention relates to the technical field of cutting processing, in particular to a double-sided groove-shaped indexable cutting insert for finishing. Background technique [0002] With the continuous development of mechanical cutting in the direction of automation, high speed and precision, higher requirements are put forward for the machinability of materials, and the requirements for CNC tools are also getting higher and higher. The following mainly introduces the machining of two typical parts: In the first case, the blanks of the slender shaft parts are made by the precision forging process, and the machining allowances reserved for the blanks and the processed parts are getting smaller and smaller. The requirements are also getting higher and higher, and the tool is required to not only withstand the impact of the black oxide skin on the surface of the processed blank, but also have the sharpness of the cutting edge of the tool in the processi...
