Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a three-beam structure of a gantry grinder. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishers. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc.; they can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as high-power grinding.

[0003] Most existing grinders only have one grinding head for grinding workpieces, which results in low workpiece grinding efficiency and a single grinding orientation. The workpiece may need to be disassembled and assembled multiple times, thus reducing the processing efficiency. This needs to be improved. Utility Model Content
