Embodiment Construction

[0015] The method of the invention is a polishing method capable of processing polygonal or curved workpieces. As shown in the figure, when the polygonal or curved surface workpiece 2 is ω 工件 When rotating at a certain speed, the linear velocity of each polishing point changes due to the change of its radius R; at the same time, when the workpiece 2 pushes the polishing wheel 1 and polishing wheel 3 away, the polishing pressure F will also change, thus affecting the workpiece. The power of the rotating servo motor changes. The method of the present invention utilizes the polishing wheel driven by the air cylinder to act on the workpiece, utilizes the computer to collect the load signal of the servo motor that drives the workpiece to rotate, and controls the rotational speed of the workpiece through the numerical control program ω 工件 and the polishing pressure F of the polishing wheel on the workpiece; make the polishing pressure F and the workpiece speed ω 工件 respectively sa...

Abstract

The invention discloses a polishing method for polygonal or curved workpieces. The polishing method is characterized by comprising the steps of utilizing a numerical control program of a computer to collect the load signal of a workpiece rotary servo motor, and respectively controlling the rotary speed omega of the workpiece and the polishing pressure F of a polishing wheel for the workpiece. The polishing method belongs to a continuous soft shape-following constant pressure variable speed control method and is suitable for the polishing of the polygonal or curved workpieces, the glass is uniform in polishing without lines and the polishing precision and polishing efficiency are improved.

Description

technical field [0001] The invention belongs to a numerical control polishing method, in particular to a polishing method for a polygonal or curved workpiece. Background technique [0002] With the continuous popularization of mobile phones and the rapid development of electronic products such as LCD TVs, the application of glass grinding and polishing machines has grown rapidly. The display glass of the mobile phone, the casing of the mobile phone, and the casings of MP3 and MP4 are all processed by polishing machines. [0003] At present, the polishing method for products such as mobile phone glass basically adopts a flat polishing machine, that is, the polishing disc is a circular flat structure. Mobile phone glass mainly polishes its periphery, and the polishing must be done in steps, that is, after polishing one side, turn the workpiece at an angle, fix it and then polish the other side, so that the workpiece can be processed repeatedly. The existing polishing method ...
