Abstract
The invention discloses a nano ceramic cutting tool for processing automotive axle shafts. The nano ceramic cutting tool is characterized in that during manufacturing of the nano ceramic cutting tool, 2% of TiN nanoparticles are added into a matrix TiC, major reasons of refinement of a metal microstructure and improvement of mechanical property are related to motion that TiC crystal particles can be effectively pinned by the TiN nanoparticles distributed in positions of crystal boundaries of the matrix TiC, a nano TiN reinforced metal ceramic mechanism has functions of refinement, diffusion, reinforcement and solution strength, and nano can modify the metal ceramic cutting tool and is high in cutting property and wear mechanism; compared with YT15 hard alloy and a YG 8 hard alloy cutting tool, nano-modified metal ceramic cutting tool is remarkably longer in service life when cutting 45# steel, alloy steel, quenched steel, stainless steel and highly hard cast iron.
Description
Technical field
The present invention relates to process tool, be specifically related to a kind of automobile axle shaft processing Nano-scale Ceramic Tool.
Background technology
The material of automobile axle shaft is generally 45 steel and steel alloy, the YT series hard alloy that traditional process tool adopts, the operation of roughing section adopts YT5 type tool sharpening, and the operation of semifinishing section adopts the hard alloy cutter of YT15 type, the employing YT30 type carbide alloy processing of finishing section.YT type cutter still relatively adapts at the not treated semiaxis of processing, but at present along with the speed of automobile and the raising of moment of torsion, automobile axle shaft need improve through heat treatment mechanical performance and the mechanical strength of automobile axle shaft, and tungsten titanium class cutter can not adapt to the performance requirement of machining for processing the after heat treatment semiaxis of high rigidity, the alternative tungsten titanium class cutter of novel cutter was constantly being tested, sought in the manufacturer of automobile axle shaft in recent years.
Summary of the invention
The object of the invention is to: a kind of automobile axle shaft plus nano pottery process tool is provided, utilizes the modern high-intensity automobile axle shaft of this Nano-scale Ceramic Tool processing, can improve significantly crudy and production efficiency.
The technical scheme that technical solution problem of the present invention adopts is: a kind of automobile axle shaft processing Nano-scale Ceramic Tool, the nano TiN particle of the main cause that cermet structure refinement and mechanical property improve and the distribution of matrix TiC grain boundaries can effectively pin TiC crystal grain motion relevant, nano TiN strengthens ceramic-metallic mechanism refinement, disperse, the function of strengthening and solution strengthening, nanometer can modified metal-ceramic cutter and higher cutting ability and abrasion mechanism, at cutting 45# steel, steel alloy, hardened steel, when stainless steel and high hard cast iron, compare with YG8 hard alloy cutter with YT15 carbide alloy, the ceramic tool life-span of nano modification significantly improves.
The invention has the beneficial effects as follows: nano ceramics process tool long service life, can cut high hard hardened steel, good product quality, operating efficiency is high.
The specific embodiment
When ceramic tool is manufactured, in its matrix TiC, increase by 2% nano TiN particle, the nano TiN particle of the main cause that cermet structure refinement and mechanical property improve and the distribution of matrix TiC grain boundaries can effectively pin TiC crystal grain motion relevant, nano TiN strengthens ceramic-metallic mechanism refinement, disperse, the function of strengthening and solution strengthening, nanometer can modified metal-ceramic cutter and higher cutting ability and abrasion mechanism, at cutting 45# steel, steel alloy, hardened steel, when stainless steel and high hard cast iron, compare with YG8 hard alloy cutter with YT15 carbide alloy, the ceramic tool life-span of nano modification significantly improves.
The invention has the beneficial effects as follows: nano ceramics process tool long service life, can cut high hard hardened steel, good product quality, operating efficiency is high.
