Automatic Control Technology of Grinding Zone Temperature in Grinding Hardening

Abstract:

In grinding hardening process, part’s surface (grinding zone) temperature directly affects the quality of surface layer of heat treatment. The high temperature heat pipe is very good device of control heat transfer. In order to make the grinding zone temperature slightly change in grinding process, this paper describes a design of temperature automatic control technology. A high temperature heat pipe contact with the part’s grinding zone. The zone temperature is measured using infrared radiation pyrometer and the temperature data will be used to control the high temperature heat pipe’s thermal resistance through the PID controller. That is that the PID controller will adjust the contact area between part and high temperature heat pipe, thus achieves control of part’s surface hardening requirements.
