Abstract

The invention discloses a thermoelectric refrigeration grinding wheel and a self-condensation minimal quantity water lubrication precision grinding system with the same. The thermoelectric refrigeration grinding wheel comprises an annular grinding wheel grinding layer, a refrigeration device and a circulation heat dissipation device. Workpieces can be ground by the grinding wheel grinding layer togenerate heat during work. The thermoelectric refrigeration grinding wheel and the self-condensation minimal quantity water lubrication precision grinding system have the advantages that a thermoelectric refrigeration sheet is used as a refrigeration portion, the heat generated during grinding can be transferred to a hot surface by the electrified thermoelectric refrigeration sheet by the aid ofheat pump principles, and heat gathered on the hot surface can be taken away by a circulation heat dissipation system; trace condensed water can be carried to grinding zones under low-temperature condensation effects of the surfaces of the thermoelectric refrigeration grinding wheel, accordingly, minimal quantity lubrication effects can be realized, and self-condensation minimal quantity water lubrication grinding can be implemented; the thermoelectric refrigeration grinding wheel and the self-condensation minimal quantity water lubrication precision grinding system can be mounted on differenttypes of grinding machines including surface grinding machines, cylindrical grinding machines, curved surface grinding machines and the like and can be applied to the different types of grinding machines.

Description

technical field [0001] The invention belongs to the field of precision grinding, and relates to a grinding wheel using a thermoelectric refrigeration sheet for internal cooling and a self-condensing micro-water lubricating precision grinding system comprising the grinding wheel. Background technique [0002] During the grinding process of the grinding wheel, the abrasive grains and bonding agent on the surface of the grinding wheel generate a large amount of grinding heat by scratching and plowing the workpiece material in the grinding area, and the grinding heat will change the surface quality and mechanical properties of the processed material , and even cause burns on the surface of the material; accelerate the wear of the grinding wheel and affect the life of the grinding wheel; cause thermal deformation of the grinding wheel and the workpiece, affecting the accuracy of a few inches or the shape of precision parts on a plane or various curved surfaces, so it is necessary ...
