Description

Technical Field

[0001] The utility model relates to the technical field of mirror inner circle polishing machines, in particular to a mirror inner circle polishing machine. Background Art

[0002] In the early days, internal machining relied primarily on traditional lathes and grinders, resulting in low process efficiency and uncertain surface quality. Smooth surfaces often relied on manual polishing, which was inefficient and inconsistent. With the advancement of automation and mechanization, polishing machines began to be introduced, but most equipment was still manually controlled, resulting in complex processes and limited production. At this time, polishing machines primarily used abrasives. The introduction of CNC technology has greatly improved the automation level of internal polishing machines, significantly enhancing their accuracy and repeatability. Simultaneously, the development of computer-aided design (CAD) and computer-aided manufacturing (CAM) has facilitated the optimized design of equipment structures. A mirror internal polishing machine consists of a mainframe, worktable, drive system, spindle, grinding head, and feed system. However, existing mirror internal polishing machines produce a blurred, horizontally streaked finish on the inside of the mirror surface during use. Therefore, a solution to these technical issues was needed. Utility Model Content
