PCT No. PCT/SU86/00039 Sec. 371 Date Feb. 11, 1988 Sec. 102(e) Date Feb. 11, 1988 PCT Filed Apr. 30, 1986 PCT Pub. No. WO87/06512 PCT Pub. Date Nov. 5, 1987.A method of thermal deburring of metal parts which is carried out in a chamber in two stages. The chamber is initially filled with a mixture of a combustible gas and air, the amount of each component in the mixture and the pressure thereof being dependent on the necessity to ensure the burning-out of oils and evaporation of moisture from the surface of parts being treated. The mixture is subsequently ignited. As a result, the moisture evaporates, and the oils burn out. Products of combustion are then expelled from the chamber. Then the chamber is filled with a mixture of a combustible gas and oxygen and the mixture is ignited, and the burrs on the parts are burnt down.
