Abstract
A cutting processing method for a room temperature vulcanization (RTV) silicon resin part containing hollow glass beads comprises performing cutter selection by trial cutting; determining a cutter for processing an RTV silicon resin coating; selecting a lathe device; determining cutting parameters which comprise a rotating speed, a cutting depth and the feeding amount; performing trial cutting on a plurality of cutters, comparing the cutting parameters and the influences on luminosity of the surface of the part, adjusting the cutting parameters again if the parameters are not reasonable and layer flaking and bubbles occur so that inaccuracy of dimensional tolerance, high roughness and coating damage are caused; or else directly performing cutting processing of the part. According to the cutting processing method for the RTV silicon resin part containing the hollow glass beads, the bottlenecks that an RTV silicon resin material can only be formed by pouring, the dimensions are inaccurate and performances of an engine are influenced are solved. After on-site application, the processing effect of the coating is extremely good, the state is stable, the application prospect is wide, and the coating can be used on engines of other models.
