Product Details

1Cr11Ni2W2MoV/13Cr11Ni2W2MoV is a kind of heat resistant stainless steel, which is widely used as the material of  aeroturbine  blades  owing  to  its  generally  outstanding  mechanical  property  such  as  excellent toughness,  oxidation  resistance  and  corrosion  resistance.  Since  strict  requirements  of  geometric accuracy  and  surface  quality  have to  be  fulfilled,  grinding  process  is  always  applied  as  the  final finishing of the  blades [1].Unfortunately, mechanical properties  of high temperature stainless steel 1Cr11Ni2W2MoV make it difficult to grind and may lead to elevated temperatures at the grinding zone and possible grinding burn on surface of the workpiece during grinding with abrasive wheels, which  deteriorate  the  surface  quality  of  the  workpiece  seriously. Extensive  research  has  been carried out on the surface integrity when grinding high temperature alloy and titanium alloys [2-5], and few studies on grinding burn mechanism of stainless steel was reported. Demands  on  reducing  the  grinding  costs  and  increasing  grinding  efficiency  have  been  posing continuous  challenges  for  the high  temperature  stainless  steel’ grinding technologies.  The  sol-gel alumina abrasive wheel is a new type of grinding wheel developed in recent years. There have been no profound studies reported on the grinding characteristic of high temperature stainless steel with SG wheels.
