Abstract

The invention relates to a flexible polishing head. The flexible polishing head consists of a main material and an auxiliary material, wherein the main material comprises silica gel, a silica gel curing agent and a wetting agent; the auxiliary material comprises monocrystal diamond, cerium oxide, silicon carbide, aluminum oxide and magnesium oxide; the weight ratio of the silica gel to the auxiliary material is 1 to (1-3); the weight ratio of the silica gel curing agent to the silica gel is (1-5) to 100; the flexible polishing head is prepared from the following raw materials in parts by weight: 0.5-1 part of the wetting agent, 10-15 parts of the monocrystal diamond, 31-37 parts of the cerium oxide, 20-25 parts of the silicon carbide, 20-25 parts of the aluminum oxide and 3-4 parts of the magnesium oxide. The flexible polishing head has high structure homogeneity and polishing consistency, can be applied to ultra-precise polishing of glass materials, and is high in polishing performance.

Description

technical field [0001] The invention belongs to the technical field of soft polishing grinding heads, and in particular relates to a soft polishing grinding head for grinding, polishing and deburring hard and brittle materials such as glass and gemstones and a preparation method thereof. Background technique [0002] Glass materials are typical hard and brittle materials with poor processability. The strength limit of glass is very close to the elastic limit, and fracture failure will occur when the glass bears a load slightly exceeding the elastic limit. The polishing process is the last processing process of glass products, and the ultra-precision polishing of glass now requires a bright surface effect, without scratches, chipping, non-transparent, fragments and other adverse effects. [0003] The main economic and technical indicators of glass product polishing are characterized by polishing efficiency, dimensional accuracy of the processed glass edge, brightness, consum...
