Problems solved by technology

[0003] Due to the small thermal conductivity of oil and PEG, it is not conducive to heat dissipation of the workpiece
It is difficult to clean the workpiece surface with oil cutting fluid, which requires pickling, which wastes resources and pollutes the environment. PEG is water-soluble and easy to clean, but its suspension system is dynamic and stable. Once it is still, it will precipitate and stratify. At this time, it is difficult to Disperse to form a homogeneous suspension
In addition, the suspension and dispersion of hard material particles in oil or PEG is based on their viscosity, and the viscosity of oil or PEG is usually determined, so that when cutting, the cutting speed is relatively fixed. If it is higher than this speed, it will smoke, Carbonization, so the variety and range of applicable crystals for this type of cutting fluid are limited
[0004] When the hard material particles are recovered, a large amount of oil or PEG is discharged, which is wasteful and not conducive to environmental protection

Abstract

The wettable grinding powder includes assistants and granular hard material in the weight ratio of 1 to 1-5. The assistants include wetting agent and dispersant in the weight ratio of 1 to 1-2 and slow releasing agent accounting for 0.5-1 wt%, the wetting agent is white tea seed residue, tea seed residue and / or gleditschia horrida powder; and the dispersant is anionic surfactant and / or non-ionic surfactant. The granular hard material is selected from titanium nitride, alumina, silicon carbide, diamond, etc and has fineness not lower than 1200 mesh. The wettable grinding powder is added with pure water to compound suspension liquid in the concentration of 20-50 wt%, and the suspension liquid has high grinding efficiency and wide application in cutting, polishing and hard stratum drilling.

Description

1. Technical field [0001] The invention relates to an auxiliary material for mechanical precision cutting, especially wire cutting, in particular a wettable grinding powder. 2. Background technology [0002] Cutting fluid and polishing fluid are indispensable auxiliary materials for mechanical precision cutting and polishing. Cutting fluid and polishing fluid are usually suspensions composed of solvents and dispersion media. For example, wire cutting of crystals traditionally uses cutting fluid composed of hard material particles dispersed in oil, but currently commonly used is a cutting fluid composed of hard material particles dispersed in polyethylene glycol (PEG). The sawdust suspension for cutting wafers as disclosed in CN1180726A is to disperse hard material particles in PEG. [0003] Due to the small thermal conductivity of oil and PEG, it is not conducive to heat dissipation of the workpiece. It is difficult to clean the workpiece surface with oil cutting fluid, wh...
