Turbine expansion refrigeration high-speed grinder

Abstract

The invention belongs to the technical field of grinding equipment and discloses a turbine expansion refrigeration high-speed grinder. The turbine expansion refrigeration high-speed grinder mainly comprises three parts, i.e. a high-speed air compressor, a turbine expander and a high-speed motor grinder, wherein air is compressed through the high-speed air compressor, the compressed air is guided into the turbine expander and is cooled to low temperature through the turbine expander, then air with temperature of negative 45DEG C is directly fed into a heat preserving chamber of the high-speed motor grinder and finally an electric spindle is adopted in the heat preserving chamber to drive a high-speed grinding head to realize cooling grinding to an object. The surface precision of the ground object is high, the stability is good, consumables are not needed during grinding, the machining cost is low, the efficiency is high, the turbine expansion refrigeration high-speed grinder not only is applicable to grinding and polishing of hard and fragile materials such as optical glass, ceramic and gemstones, but also is applicable to the grinding and polishing of steel materials with higher hardness, and the precision machining of the object is realized.

Description
