Abstract

The invention discloses a hydrophilic diamond-suspended grinding and polishing solution and a preparation method thereof. The hydrophilic diamond-suspended grinding and polishing solution comprises the following raw materials in percentage by weight: 0.05-15% of diamond powder, 0.005-15% of suspending agent, 0.005-12% of surfactant, 0.05-60% of friction modifier, 0.0005-5% of pH value regulator and the balance of dispersion medium. The hydrophilic diamond-suspended grinding and polishing solution provided by the invention can keep a stable and uniform state for a long time and can not cause precipitation, sedimentation and inactivation phenomena; and the suspending medium plays a role of a suspending carrier and also has the effects of cooling, lubrication and chip removal in the grinding and polishing process.

Description

technical field [0001] The invention relates to a diamond suspension grinding and polishing liquid and a preparation method thereof, in particular to a hydrophilic diamond suspension grinding and polishing liquid and a preparation method thereof. Background technique [0002] High efficiency, high precision and automation are the goals pursued by modern grinding technology. With the continuous emergence of high-tech products, the machining accuracy and surface integrity are getting higher and higher, and traditional grinding is developing in the direction of ultra-precision grinding, ultra-precision grinding and polishing.
