The invention discloses an automatic irrational number speed ratio grinding and polishing machine. The automatic irrational number speed ratio grinding and polishing machine comprises a traditional grinding machine, a connecting seat, an X-axis movable sliding table, a Y-axis movable sliding table, a Z-axis movable sliding table, a driving rotation motor, a driving synchronous pulley, a driven synchronous pulley, a motor driving shaft, a driving shaft, an upper grinding and polishing disc, a lower grinding and polishing disc and a movable plate. According to the automatic irrational number speed ratio grinding and polishing machine, irrational number rotation is conducted through the driving rotation motor, the driving shaft is controlled to conduct irrational number rotation, the requirement of the upper grinding and polishing disc and the lower grinding and polishing disc for the irrational number speed ratio can be met, thus, the problem that grinding paths of grinding particles on a workpiece are repeated under the condition of the rational number speed ratio is solved, the surface quality of planar grinding machining is improved, and ultra-smooth and low-damage machining of the surface of the workpiece is achieved; and through a strip-shaped hole in the motor driving shaft, the situation that an upper grinding disc spindle and a lower grinding disc spindle are locked when the feeding amount is too large can be effectively prevented, and the safety of grinding and polishing is improved.

Description

technical field [0001] The invention relates to the technical field of ultra-compact grinding and polishing, and more specifically, relates to an automatic grinding and polishing machine with an irrational number speed ratio. Background technique [0002] The current ultra-precision machining technology is based on the premise of not changing the physical properties of the workpiece material to obtain very high shape accuracy, dimensional accuracy, surface roughness, and surface integrity (less surface damage, including residual stress, tissue changes, microcracks, etc.) and other defects) as the goal, it is an important support for cutting-edge technology industries such as aerospace, weapons and national defense, and optoelectronic information. As an important means of ultra-precision machining, grinding and polishing uses fine abrasive grains as the processing medium. Grinding is usually used as a process before polishing. The purpose is to improve the surface accuracy o...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that traditional plane grinding and polishing generally adopts rational number rotation speed ratio trajectory for grinding and polishing processing. When the workpiece is processed, the grinding trajectory of the abrasive particles on the workpiece is repeated, which may easily lead to a decrease in the roughness of the surface of the workpiece. Defects such as corrugation and orange peel are formed on the surface, and an automatic irrational number speed ratio grinding and polishing machine is provided. Through irrational number rotation, the problem of repeated abrasive grain trajectory is solved, and uniform grinding without dominant direction is obtained on the surface of the processed workpiece. track
