▎ 摘　　要

NOVELTY - The tool holder (1) comprises a cutting tool (3) through the thermal transfer interface (4) with having contact with cutting tool with the circulating fluid and nanofluid. The fluid is circulated forcibly by natural convection or by an electric field or magnetic field. The circulation of nanofluids includes base fluid and nanoparticles. The base fluid can be water, ethylene glycol, ethylene, refrigerants, oils and lubricants, biofluids, polymeric solutions. The nanoparticle materials includes chemically stable metals like gold, copper and oxides like alumina, silica, zirconium, titanium , copper, metallic carbides and carbon like diamond, graphite, graphene, carbon nanotubes and fullerene. USE - Tool holder for fixing cutting tool used during chip formation process. ADVANTAGE - Tool holder is made of resistant materials to prevent deformations. Wear and life of cutting tool can be improved. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of tool holder for fixing cutting tool used during chip formation process. (Drawing includes non-English language text). Tool holder (1) Tool bump (2) Cutting tool (3) Thermal transfer chamber (5) Outlet channel (6)
