METAL POWDER PROCESSING EQUIPMENT

摘要

In metal powder processing equipment where metal powder is sequentially laminated on a table of a chamber and laser beam melting or electron beam melting is performed or cutting and shaping are performed by a rotating tool subsequent to the melting, a first temperature adjusting unit is placed at a lower bottom portion of the table and a second temperature adjusting unit is disposed with the state of contacting to said outer wall around all outer wall of the chamber and both units are simultaneously heated or cooled. Further, a room partially enclosing a metal powder reserve tank and a metal powder supply pipe is provided with a third temperature adjusting unit, and temperature of the third temperature adjusting unit is set to average temperature of the second temperature adjusting unit before the second one actuates. Consequently, deterioration of dimensional precision in processing and deterioration of metal powder quality can be prevented by keeping heating temperature constant.
