GH4169 Multi-step Deep Hole Tool Design and Test Research
摘要
Abstract
Aiming at the problems of difficult to ensure coaxiality,large cutting force,high cutting temperature,difficult to control chip shape,low tool life,difficult chip removal,large work hardening tendency and difficult to observe in the machining process of difficult-to-machine material GH4169 multi-step deep hole parts,the machining process of multi-step deep hole is formulated,including the selection of appropriate machining equipment,machining system,tool size,tool material,cooling and lubrication methods.At the same time,considering the coaxiality problem of multi-step deep holes,a front positioning push-boring tool with internal chip removal mode is designed.The orthogonal test method is used to carry out the GH4169 multi-step deep hole boring test.By changing the three parameters of spindle speed,feed rate and cutting fluid flow,the machine tool state,vibration tool condition,chip removal condition,tool wear condition,guide block wear condition,chip shape,hole axis line deflection and other parameters in the process of deep hole boring are analyzed.The best parameter combination for boring is 40 mm inner hole,spindle speed is 225 r/min,feed rate is 0.04 mm/r,cutting fluid flow is 120 L/min.关键词
