Abstract
Comparative cutting tests have been carried out on a horizontal milling machine, having the worktable fitted, in turn, with pressurized oil "single phaseflow"bearings,pressurized mixture flow, and a conventional lub-ricational system. Special table and saddle for that machine were designed and manufactured to be capable for applying all methods of lubrication. Awide range of depth of cuts and feed rates were used. Both surface roughness and vibrational parameters were measured. The use of pressurized oil and mix- ture flow bearings slideways increase the machine stability and produced more fine surface roughness than conventional lubrication slideways.
