FIELD: machine engineering, namely trimming openings and burrs remained on edges after mechanical working.
SUBSTANCE: apparatus includes base 1, working chamber with sealing lid 11 and heat-removing sleeve 3 with bottom 4 arranged in said chamber. Bottom of sleeve 3 may perform axial motion relative to sleeve. There is cavity between sleeve bottom and bottom portion of chamber body; said cavity is communicated with inter-jacket space filled with liquid and arranged between outer wall of sleeve and inner wall of chamber body. Annular protrusion is formed on inner wall of sleeve directly over its movable bottom. Annular flange 7 is formed in mean portion on outer surface of sleeve for dividing inter-jacket space by upper and lower cavities. One-way valves 8 are mounted in body of flange. Release valve 12 is mounted in outer wall of housing. Floating ring 9 is arranged in upper cavity of inter-jacket space and floating ring 5 is arranged in lower cavity of said space.
EFFECT: enlarged manufacturing possibilities of apparatus.
