Design of Automatic Control System of Grinding Zone Temperature in Grinding Hardening

Abstract:

The grinding hardening is a new technology which utilized thermal of grinding zone to heat-treat the workpiece surface layer. In grinding hardening process, 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 workpiece’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 workpiece and high temperature heat pipe, thus achieves control of workpiece’s surface hardening requirements.
