Description

Technical Field

[0001] The invention relates to the technical field of grinding, and in particular to a gear grinding device with an adjustable grinding roller. Background Art

[0002] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough objects to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness. Grinding can be divided into manual grinding and mechanical grinding. Manual grinding refers to the method in which workers use handheld grinding tools to grind workpieces. This method is suitable for small products or workpieces with complex shapes. The main tools are sandpaper, grindstones and polishing paste. Manual grinding needs to pay attention to maintaining a certain pressure and angle to ensure uniform grinding effect. Its advantages are flexible operation and precise control of details, but the efficiency is relatively low. Mechanical grinding is a method of grinding workpieces through mechanical equipment. It is suitable for mass production or processing occasions requiring high efficiency. Common mechanical grinding equipment includes grinding wheels, polishing machines and grinders. The advantage of mechanical grinding is that it can grind quickly and efficiently, but it is relatively difficult to operate for workpieces with complex shapes.
