To meet the requirements of surface quality and machining precision stainless steel parts, usually by grinding method Coefficient of thermal conductivity small because of the large stainless steel toughness modulus of elasticity is small, so the problems are as follows: in grinding wheel adhesion jams easily; Machining surface is easy to burn; Severe hardening phenomenon; It is not hard to see that the selection of grinding wheel and grinding fluid directly influences the grinding efficiency and machining accuracy. This paper studies the factors that influence the adhesion and surface roughness

Experimental conditions and methods: choose 1 gr18ni9ti specimen material, its mechanical properties: sigma b = 530 mpa sigma = 40% hardness HB = 187. The specimen size phi phi 50 mm in length 300 mm diameter cylindrical surface finish turning 50, two end centering on MGB1420 experiment on the cylindrical grinder, grinding wheel for P400 40, 203 for vertical cylindrical grinding grinding way, in order to improve the reliability of the test results, the repeated test, the average effect observation, to eliminate the influence of random factors, at the same time keep the grinding conditions, by changing the grinding wheel abrasive grain hardness, replace the dosage of grinding fluid to check for grinding effect

Experiment results analysis of the grinding wheel grain size effect on the rate of adhesion: choose white corundum hardness 60 80 K size 36 46 respectively four wheel, the specimen longitudinal grinding, cylindrical grinding length is 600 mm, the detection rate of adhesion, the grinding wheel is fine, adhesion, this is because there is a hole between abrasive grain and grinding chip can deposit in empty; And the smaller the grinding wheel, the smaller the hole, the grinding wheel quickly loses the space, causing the blockage
