Grinder (grinding machine) is a machine tool that uses abrasive tools to grind the workpiece surface. Most grinders use high-speed rotating grinding wheels for grinding, and a few use oilstone, abrasive belt and other abrasives and free abrasives, such as honing mill, superfinishing machine tool, abrasive belt grinder, grinder and polishing machine.

In terms of structure - the main castings of the machine are made of high-grade cast iron and annealed to eliminate internal stress, so as to ensure high precision, high rigidity and prolong the service life of the machine.

In terms of slideway - the left, right, front and rear double V slideways of the machine are pasted with wear-resistant resin turcite-b, and are precision spaded. It not only slides smoothly but also is wear-resistant. It is most suitable for molding and grinding.

In terms of spindle - the direct spindle with elastic barrel integrated design is used, and P4 grade ultra-precision inclined roller bearing is adopted. Under high-speed rotation, it has low noise, no vibration and large torque. It is suitable for heavy cutting and all kinds of forming grinding
