Abstract

The invention discloses a heavy cutting waveform guide chip turning and milling compound blade, belongs to the technical field of cutters for heavy cutting, and aims to solve the problems of bad cutter failure, short life and low working efficiency caused by difficult cutter chip breaking, weak heat dissipation and low strength in heavy turning and milling process. The blade takes the shape of a regular four-edge table; negative chamfering cutting edges are respectively machined on the outer edges of four straight lines of the front cutter surface of the blade; triangular reinforced projections with slopes on one side surfaces are respectively arranged on the parts, near four cutter points, of the front cutter surface of the blade; the parts, near the four chamfering cutting edges, of the front cutter surface of the blade respectively provided with multiple strip-shaped projections and multiple spherical projections; a square boss is arranged in the middle area of the front cutter surface of the blade, and is provided with a fastening screw hole in the geometric center; a chip holding groove is defined by the four side surfaces of the square boss and the front cutter surface; and the four side surfaces of the square boss are all waveform chip guide surfaces with slopes. The heavy cutting waveform guide chip turning and milling compound blade is specifically suitable for machining of water chamber seals.

Description

technical field [0001] The invention relates to a heavy-duty turning and milling compound blade, which belongs to the technical field of cutting tools for heavy-duty cutting. Background technique [0002] Nuclear power nuclear island AP1000 evaporator water chamber head (hereinafter referred to as water chamber head) is the most advanced and most difficult part of the third-generation nuclear power plant equipment in the world today, and is the key equipment in the pressurized water reactor nuclear power plant. Large in size and heavy in weight, the purity and density of the material and various physical, chemical and mechanical performance indicators are very high. It is a high-tech product that integrates materials, smelting, forging, heat treatment, flaw detection and measurement. [0003] The material of the water chamber head is high-strength low-alloy 508III steel, which has high plasticity and good high-temperature mechanical properties. Its main processing methods ar...
