Description

Technical Field

[0001] The utility model relates to the technical field of glass turning, in particular to a turning structure for uniform-speed grinding of glass. Background Art

[0002] Grinding is a common finishing method in mechanical processing. It uses high-speed rotating grinding wheels and other abrasive tools to cut the surface of the workpiece. It has the characteristics of small processing volume and high precision. In the mechanical manufacturing industry, grinding is widely used. The objects of grinding mainly include carbon tool steel and carburized quenched steel parts that have been heat-treated and quenched. However, glass workpieces, such as mobile phone screens and computer screens, are small in size, brittle in texture, and high in hardness. During the grinding process, a slight shake of the grinding head may cause uneven force on the glass, resulting in cracks or even breakage. Generally, slow feed is used during processing to avoid shaking of the grinding head, which results in low grinding production efficiency.

[0003] When grinding glass, it is necessary to turn the glass over. However, when some devices grind glass of different sizes, it is necessary to consider that different sizes of glass need to be adapted to different device structures. Therefore, it is necessary to propose a turning structure for uniform speed grinding of glass. Utility Model Content
