In this paper, plunge grinding experiment was conducted on 20CrMnTi with monolayer brazed cubic boron nitride (CBN) wheel. Surface integrity was evaluated through morphology observing and roughness testing. It is found that surface roughness Ra is lower than 0.8μm. Grinding forces were measured and the effects of process parameters (i.e. workpiece speed and depth of cut) on grinding forces were studied. The changing regulation of specific grinding energy with the increase of equivalent chip thickness was revealed. The result shows that both grinding force and specific energy are lower comparing with white fused alumina (WA) wheels. In general, monolayer brazed CBN wheels perform better in grinding of 20CrMnTi than WA wheels.
In this paper, grinding forces of titanium alloy Ti-6Al-4V are measured during creep feed grinding with brazed cubic boron nitride (CBN) wheels. The effects of process parameters on grinding force, force ratio and specific grinding energy are investigated in detail. The grinding force is low and force ratio is about 1.5, and the specific grinding energy of titanium alloys Ti-6Al-4V is about 65J/mm3. Also, CBN wheels brazed with composite filler of Ag-Cu-Ti and 0.5wt.% lanthanum show better grinding performance than the counterpart brazed with Ag-Cu-Ti filler in this investigation.
