Difficult-to-machine material forming grinding cooling state monitoring device

Abstract

The invention discloses a forming grinding cooling state monitoring device for a material difficult to process. The forming grinding cooling state monitoring device comprises a temperature measurement part, a coolant pressure measurement part, a data acquisition card and a computer. Signals measured by the temperature measurement part and the coolant pressure measurement part are collected by the data acquisition card and then transmitted to the computer through a data line to be stored and processed. After stored and processed through the computer, the collected data can provide the basis for optimization of grinding process parameters and a cooling mode, the problem of burning of the workpiece molded surface in the forming grinding process of the material difficult to process is further solved, and forming grinding efficiency is improved.

Description

technical field The invention relates to an industrial processing process monitoring device, in particular to a cooling state monitoring device for high-efficiency forming grinding of difficult-to-process materials. Background technique The biggest problem in slow grinding of difficult-to-machine materials is grinding burns, especially sudden burns. At first, this phenomenon was not well explained theoretically. It was not until Professor Andrew of the University of Bristol introduced the boiling heat transfer technology in the field of thermal engineering in the 1970s that this phenomenon was explained. It points out that in the slow grinding process, when the grinding heat flux is close to but not exceeding the critical heat density, the grinding fluid in the grinding arc area is in the stage of nucleate boiling, and the surface temperature of the workpiece at this time can be maintained below 120-130 °C , and when the grinding arc area exceeds the critical heat flux dens...
