Results of experimental research on the cutting of highly abrasive materials with abrasive reinforced circles

In order to carry out experimental studies of the process cutting highly abrasive materials with reinforced wheels, a dynamometer stand for registering force load author's design KNUCA was modified, which made it possible conduct full-fledged taking into account all valid factors interaction working environment and body during supply water zone dedust The use refractory bricks is proposed as environment, wheel strength up 60MPa used body. As result research conducted dynamometric registration study an wheel, tangential forces that perform work destruction overcoming friction between side surfaces material were analytically determined. According results theoretical studies, established limits change in resistance cutting, determined natural installation (refractories) laboratory stand, are same, nature their also similar related by similarity coefficient.
 check adequacy calculations, temporary uniaxial compression rock σв=60 MPa carried on stand. fully confirm comparison determining showed sufficient convergence and, accordingly, legitimacy using analytical expressions when calculating power parameters machines tool. maximum value error theoretically experimentally bench recording wheels Δδ=13,8%.
