Problems solved by technology

Most of the grinding wheels using these binders are used for fast cutting. These grinding wheels have the characteristics of large diameter, coarse abrasive grain size, high hardness, fast cutting speed, good wear resistance but poor heat dissipation, so in use Coolant must be added during operation, so it is only suitable for grinding in industrial fields

Abstract

The invention relates to a formulation of a grinding wheel and a production method thereof, in particular to a formulation of a miniature rubber binder grinding wheel and a production method thereof. The formulation of the miniature rubber binder grinding wheel breaks through the formulation of the convention grinding wheel; on the basis of the conventional formulation, chloroprene rubber and butadiene rubber are added, so that the grinding wheel is better in flexibility and has greatly-improved self-sharpening performance and heat dissipation, therefore, in the false tooth polishing process, the grinding wheel can polish a false tooth brightly and does not destroy the shape and the size of the false tooth and the false tooth is polished until a gloss effect of a real tooth is approached; in a production method, the conventional post-curing temperature is changed, and in a low temperature curing way, the grinding wheel is not burned out on the premise of completely curing the grinding wheel and hardness and toughness in the curing moulding process are maintained, so that wear resistance of the grinding wheel is improved.

Description

technical field [0001] The invention relates to a grinding wheel formula and a production method thereof, in particular to a rubber bond miniature grinding wheel formula and a production method thereof. Background technique [0002] The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing. Grinding wheels belong to the field of abrasives and are the most important type of abrasives in grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, bond, hardness, structure, shape and size. The characteristics of grinding wheels vary greatly depending on the abrasive, bond and manufacturing process. Commonly used bonding agents for existing grinding wheels include metal bonding agents, vitrified bonding agents, and resin bonding agents. Most of the grinding wheels using these binders are used for fast cutting. These grinding wheels have the characteristics of large diame...
