Abstract

The invention discloses a gas-liquid parallel tube type grinding wheel double laser trimming device. The gas-liquid parallel tube type grinding wheel double laser trimming device comprises gas-liquidcontrol equipment, a gas-liquid control operating platform, a picosecond laser ablation head, a gas-guide flexible pipe, a grinding machine, focusing lenses, a femtosecond laser ablation head, a femtosecond laser device, a laser device control operating platform, control equipment, a picosecond laser device, a fine water-guide pipe, a superhard grinding-material grinding wheel, a gas column flow,a liquid column flow, laser beams and three-dimensional moving platforms. By means of the gas-liquid parallel tube type grinding wheel double laser trimming device and method, the auxiliary gas-liquidparallel tube type grinding wheel double laser trimming device is provided, the situations that diamond grinding particle chip tolerance space of the grinding wheel is reduced and the height of highlighted binder is not enough caused by plasma particles and phase explosion effect are avoided, and the defects of microcracks, graphite metamorphic layers and the like generated by peripheral heat accumulation during diamond grinding are overcome; and by means of the gas-liquid parallel tube type grinding wheel double laser trimming device and the method, the generation of coulomb explosion can beavoided, the surface grating and micro-cone structure of the grinding wheel are reduced, the utilization efficiency of laser energy is improved, and the grinding wheel trimming efficiency and the trimming surface quality are improved.

Description

technical field [0001] The invention relates to a superhard abrasive grinding wheel dressing device and a dressing method, in particular to a grinding wheel double-laser dressing device with a gas-liquid parallel tube type and a dressing method thereof. Background technique [0002] Superabrasive grinding wheels include cubic boron nitride and diamond grinding wheels. Their wide application has accelerated the development and innovation of grinding technology, and has become an important symbol of technological progress in industrialized countries. Among the superabrasive grinding wheels, bronze diamond grinding wheels are the most widely used. Due to its high strength, high hardness and other characteristics, it is the most difficult to repair after blunting. At present, the mechanical method based on "head-to-head" under the action of force is widely used, but the tool loss and environmental pollution are heavy during the dressing process; the dressing efficiency is low, ...
