一、前言小深孔加工,尤其是不锈钢一类难加工材料的小深孔加工,是机械加工中的难题之一。本文主要分析了孔径为0.5～1mm、孔深超过6倍的不锈钢小深孔钻削时合适的刀具参数。二、不锈钢小深孔加工的特点不锈钢的强度和45~#钢相差不大,但它具有较大的延伸率和线膨胀系数,较低的导热率,尤其是奥氏体不锈钢1Cr18Ni9Ti有非常严重的加工硬化现象。
I. Introduction Small deep-hole machining, especially small deep-hole machining of difficult-to-process materials such as stainless steel, is one of the difficult problems in machining. This paper mainly analyzes the suitable tool parameters when drilling a small stainless steel deep hole with a hole diameter of 0.5 ~ 1mm and a hole depth of more than 6 times. Second, the characteristics of stainless steel small deep hole processing Stainless steel strength and 45 ~ # steel or less, but it has a larger elongation and linear expansion coefficient, lower thermal conductivity, especially austenitic stainless steel 1Cr18Ni9Ti have very serious Work hardening phenomenon.
