Embodiment
[0016] Examples: The following specific examples illustrate the implementation of the invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.
[0017] The indexable rack milling cutter disc is composed of a cutter body 1, an outer ring tooth blade 2, an inner ring tooth blade 3, an intermediate tooth blade 4 and a blade pressing screw 5. Cutter body 1 has ten middle-level cutting teeth 105 and ten non-middle-level cutting teeth 104, and there are two equal-sized insert grooves on the non-middle-level cutting teeth 104, which are respectively the outer ring tooth insert groove and the inner ring tooth insert groove, and the outer ring tooth The blade groove is located on the top of the rack, and the inner ring blade groove is located at the root of the rack. The outer ring blade 2 and the inner ring blade 3 are respectively installed. Both blades are LNE434-02 type blade...

The invention discloses an indexable rack milling cutter disc, which comprises a cutter body, outer ring tooth blades, inner ring tooth blades, middle tooth blades and blade pressing screws, wherein the cutter disc has ten middle layer cutting teeth and ten non-middle layer cutting teeth, LNE434-02 type outer and inner ring teeth blades of the same specification are arranged on the non-middle layer cutting teeth; an LEN446R01 type outer ring tooth blade is arranged on the middle layer cutting teeth; the planes of the three blades are inclined and stagger with one another and are fixed together with blade pressing screws of the same specification; a central hole for mounting a rotating shaft is formed in the middle of the cutter blade; a thread hole is formed in the central hole in the up and down manner and a screw for fixing the cutter blade on a rotating device is arranged in the thread hole. The indexable rack milling cutter blade adopts vertically mounted blades; cutter edges are relatively great in bearing force, relatively strong in strength and impact resistance; as a product workpiece is large in mold number and deep in tooth groove, the cutter disc is designed by adopting single angle tooth surface machining and twice rough milling is adopted, and thus the difficulty of large mold number rack machining is solved.
Description
technical field [0001] The invention relates to the technical field of machining cutters, in particular to an indexable rack milling cutter. Background technique [0002] When processing M24 large-modulus racks, because the racks are long and thick, and the hardness is high after quenching and tempering, cutting the racks with ordinary high-speed steel tools wears quickly and the efficiency is low, and it takes time to adjust the position of the machine tool and the tool, which will affect the normal production activities. How to design a rack milling cutter with wear resistance, high efficiency and easy tool setting is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to propose an improvement plan for the problems of low wear resistance and difficult tool setting in the existing M24 rack milling cutter tool, and an indexable rack milling cutter disc is designed, which improves the wear resistance, and the tool Th...
