               the  edge  corners  of  wetting.  The  wetting  of  38KhN3МFА  steel  surface  by  LCL

               solutions  is  maximum  in  the  case  of  LCLs.  It  beter  penetrates  into  the  "tool-detail"

               contact zone. The LCLs adhesion Wa is about 63,6 ∙ 10  N/m what is less than 1.7 times
               in  comparison  with  water  (110,4·10   N/m).  The  high  wettability  and  adsorption
               increase the hydrophilic of metal surface, reduce the surface energy that facilitates the

               metal machining.

                     Thermo  stability  of  LCLs  is  higher  than  oil-based  LCL  (LCLo):  during

               thermooxidation  destruction  it  is  loses  mass  (weight)  less  intensive.  The  50%  LCLs

               mass loss occurs at 400 С, LCLr at 380 С, and LCLo at 340 С. The main exothermic
               effect of combustion of products of LCLs destruction is shifted to higher temperature
               region in comparison with LCLo, which improves operation characteristics.

                     The  surface  state  estimated  by  scanning  electron  microscope  EVO-40XVP

               indicates  the  about  the  positive  effect  of  LCLs  and  LCLr  on  the  process  of

               38KhN3МFА  steel  samples  processing  after  sharpening  in  LCL.  The  spectrum

               character  and  the  quantitative  composition  of  the  shavings  revealed  Oxygen  and
               Nitrogen atoms on the steel surface what indicates on the coordination bond of valence

               electrons with the metal adsorption centers. As a result a nanofilm is formed the outer
               side of which forms the LCL organic strands.

                     The thermal destruction of LCL concentrates in the contact zone “component-tool”
               and  “shaving-tool”  is  modeled.  It  was  shown  that  the  LCLs  sample  shows  a  higher

               thermal  destruction  resistance  than  the  LCLo  sample:  the  mass  loss  of  50%  has
               observed for LCLs - at 400 C, LCLr - at 380 C, and LCLo- at 340 C.
                     The  results  of  tribological  investigations  and  the  efficiency  of  developed  LCL

               influence on processes of friction, cutting (drilling, turning) are presented. The lubricity

               of the new LCL and LCLo was estimated on R6M5-12Kh18АG18Sh steels friction pair

               by  the  friction  coefficient  between  the  tool  and  the  processed  metal.  The  friction

               coefficient was determined under load Po using the measurements indicators of friction

               moment, which were recorded by an inductive sensor of the SMT-1 machine and fixed

               by mechanical recording. The friction coefficient (under load 300 N) reduces by a factor

               of 2 in the presence of developed LCL as compared with LCLo. The uniform character
