CARBURIZING HARDENING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To shorten time required for carburizing hardening treatment of a treatment object.SOLUTION: Carburizing hardening equipment 1 is provided that includes : a treatment chamber for performing treatment on a treatment object W; a transport device for transporting the treatment object W; a placing and holding table 30 disposed in the treatment chamber and on which the treatment object transported in the treatment chamber is placed and held; and a lifting device for ascending and descending the placing and holding table 30, the transport device having a transport arm 40 for transporting the treatment object W. The carburizing hardening equipment 1 further includes: a rotary table 60 disposed in the treatment chamber and receiving and delivering the treatment object W from and to the placing and holding table 30 and the transport arm 40; and a rotary table drive device. The rotary table 60 comprises: a first support part 63 for supporting the treatment object W which has been already subjected to treatment; and a second support part 64 for supporting the treatment object which is subjected to treatment next. The first support part 63, a column support 62 of the rotary table 60, and the second support part 64 are linearly arranged in such a way that the first support part 63 and second support part 64 sandwich a rotary shaft R of the rotary table 60 in planar view.
