Problems solved by technology

Because the cutting force of rough machining, semi-finishing machining and finishing machining is very different, when the rake angle and rear angle of the tool are too large during rough machining, it will weaken the strength of the blade and reduce the heat dissipation capacity, but the service life will be reduced, so that the tool high cost

Abstract

The invention discloses a corrosion-resistant milling cutter. The corrosion-resistant milling cutter is characterized by being made of a steel bond hard alloy, wherein the steel bond hard alloy powder comprises a hard phase and a steel-based binder. According to the milling cutter disclosed by the invention, the hard phase consists of tungsten boride, silicon carbide, nickel oxide, cerium oxide and Cr, so that the mechanical property of the material is improved; and the components of the steel-based binder have relatively high strength, so that the strength of the steel bond hard alloy is further improved under the action of the hard phase.

Description

technical field [0001] The invention relates to a corrosion-resistant milling cutter, which belongs to the technical field of cutting tools. Background technique [0002] In metal cutting, reasonable selection of tool edge shape (helix angle, rake angle, relief angle, edge inclination angle) is an important condition for giving full play to tool processing performance. Reasonable selection of tool edge shape can improve tool life and achieve high-speed machining. Because the cutting force of rough machining, semi-finishing machining and finishing machining is very different, when the rake angle and rear angle of the tool are too large during rough machining, it will weaken the strength of the blade and reduce the heat dissipation capacity, but the service life will be reduced, so that the tool Costs remain high. Contents of the invention [0003] A corrosion-resistant milling cutter is characterized in that the milling cutter is made of steel bonded carbide, the steel bo...
