1, Vibration grinder
The deep processing method of using a vibration grinder tool to grind liquid and remove layers of extremely thin surface from the product workpiece is called grinding.
When grinding with a vibration grinder, diamond sand or other grinding fluid is placed in the center of the product workpiece and the grinding disc, and the material surface is crushed by the compression of the diamond sand. When the relative speed between the grinding disc and the product workpiece increases, the irregular abrasive and its rolling on the grinding disc and material surface push the broken slag and abrasive debris away. This process repeats, gradually making the material surface a smooth and precise plane. According to whether cutting fluid is used during grinding, it can be divided into wet grinding and dry grinding.
The wet grinding method has a large processing volume, and it is the initial processing. The wet grinding results in a pear skin like dark surface.
The dry grinding method has a small processing volume and is generally used for deep processing, resulting in a shiny mirror finish.
The vibration grinder is used for grinding with these materials
2, Hand grinding
Manual grinding is usually carried out in a grinding plate. The flat plate is square in shape, with a width of 300 × 300mm or 350 × 350mm. The raw material is cast iron, and the accuracy level should not be lower than - ". The flat plate is usually grouped in several pieces, and regular maintenance is necessary to ensure precision during use. When grinding the product workpiece, it should be evenly ground on the surface of the plate, and several matching flat plates should be repaired and calibrated with each other. Only by regularly maintaining the precision of the plate can good grinding quality be obtained.
3, Grinding machine
In the context of large-scale production and mechanical seal maintenance, it is necessary to use grinding machines. Grinding machines are specialized equipment for grinding flat surfaces, which can be divided into mechanical equipment such as grinding machines and electromagnetic vibration grinding machines according to their structural types. Mechanical grinders include single-sided grinders and double-sided grinders. Some highly automated grinding machines also have automatic pressurization and automatic measurement and control systems for thickness during operation, resulting in higher grinding efficiency.
