Embodiment 1

[0032] Embodiment 1 (exploring the relationship between foaming agent addition and polishing effect)

[0033] Explanation: The proportion of binder and abrasive in this formula is determined by mixing the binder and abrasive in different proportions and making splines for curing, then testing the mechanical performance indicators such as elastic modulus, tensile strength, elongation at break, etc. It is determined by screening out a large number of experimental data.

Abstract

The invention discloses a grinding-material-based foaming-agent-contained grinding wheel which is made of raw materials comprising a grinding material, a foaming agent and a binder. The polishing effect and the grinding efficiency of the grinding wheel can be controlled by adjusting the proportion of the grinding material and the foaming agent.

Description

technical field [0001] The invention relates to a grinding wheel based on abrasive materials and containing a foaming agent, which belongs to the field of abrasive tools. Background technique [0002] Various polishing and grinding tools currently produced have the following defects: compact structure, poor heat dissipation, such as resin grinding wheels (due to hydraulic molding, compact structure). [0003] General resin-bonded grinding wheels (bonded abrasives) are mainly made of abrasives and resin binders after mixing, molding, and heating and hardening. The use of this type of grinding wheel has problems such as the need for large cutting forces and serious heating of the workpiece. defect. [0004] The pores in the large porous grinding wheel (bonded abrasive) are generally filled with fillers (such as walnut shells, refined naphthalene, etc.) that can be burned (ie carbonized) at temperatures above 130 degrees during hardening treatment. fall into. However, natura...
