Description

Technical Field

[0001] The utility model relates to the technical field of sword grinding, in particular to a sword grinding machine. Background Art

[0002] In ancient times, swords were the main weapons, but nowadays, swords have come into people's sight again, such as the elderly using swords to strengthen their bodies, or swords have become home decorations. The sharpness of a sword depends on the sharpness of the blade, so when processing a sword, the blade needs to be sharpened, and the grinder has gradually replaced manual grinding. The grinder is a grinder that grinds the surface of the workpiece with a grinder coated or embedded with abrasives. It is mainly used to grind high-precision planes, internal and external cylindrical surfaces, conical surfaces, spherical surfaces, threaded surfaces and other surfaces in the workpiece. The grinder is controlled by a stepless speed regulation system, which can easily adjust the grinding speed suitable for grinding various parts. Its main types are disc grinders, shaft grinders and various special grinders.

[0003] For the grinding during the sword processing process, the grinders are mostly disc grinders. The current disc grinders require technicians to manually control the inclination angle of the blade based on their experience during the grinding process. Grinding machines that are independent of manual labor can only adapt to blades with a single inclination angle, and have poor applicability. Utility Model Content
