I. Hardware polishing equipment
1, polishing machine
Polishing machine, also known as grinder, is often used for mechanical grinding, polishing and waxing. Its working principle is that the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Because the polishing disc and polishing agent work together and rub against the polished surface, the paint surface pollution, oxide layer and shallow marks can be removed. The rotating speed of polishing disc is generally 1500-3000? R/min, mostly stepless speed change, can be adjusted at any time according to needs during construction.
(1) Power sources are pneumatic and electric. Pneumatic type is safer, but it needs air source; Electric power supply is easy to solve, but we must pay attention to the safety of electricity use.
(2) According to the function, there are two kinds of dual-function industrial grinding and polishing machines and simple polishing machines. Dual-function industrial abrasive polishing machine can be equipped with grinding wheel to polish metal materials, and can also replace polishing disc to protect car paint. This machine is heavy, 2-3? Kg, but it works very smoothly and is not easy to be damaged. This model has adjustable rotating speed and is suitable for professional beauty care personnel. A simple polishing machine is actually a drilling machine, which is small in size and cannot adjust the rotating speed, so it is difficult to grasp the balance when using it. Professional beauty care workers generally don't use this kind of machine.
(3) According to the rotating speed, there are three types of polishers: high-speed polishers, medium-speed polishers and low-speed polishers. Speed of high-speed polisher 1750-3000? R/mAn, adjustable speed; The rotating speed of the medium-speed polishing machine is 1? 200— 1? 600? R/rain, adjustable speed; The rotating speed of the low-speed polisher is 1? 200 rpm, the speed is not adjustable.
Second, the difference between hardware grinding and polishing
Grinding: refers to grinding off the big burr and welding slag on the surface of the workpiece with a grinder and grinding wheel or shutter;
Polishing: after polishing the surface of the workpiece with a polishing machine and further processing such as installing cashmere polishing sheets, a smooth surface can generally be obtained, and some demanding ones can achieve a mirror-like finish, but generally they cannot;
At present, there are some industrial robots in the market that integrate grinding and polishing, such as Yuyang Industry, which specialize in processing hardware, replacing manual efficient operation, intelligent programming operation, and cooperating with double-station workbench, automatic grinding system, intelligent vision system and intelligent control system to realize full-automatic processing.
The above introduction about the difference between hardware grinding and polishing tells us the difference between them, and it is not difficult to know that polishing is relatively more delicate, which is one of the operation steps and methods that must be referred to in the pursuit of high-quality products. In addition, the above first involves the knowledge of equipment. We take the polishing machine that plays an important role in it as an example, and analyze its product category, application scope and advantages according to its basic knowledge.
