Due to various processing requirements, the design and development of cylindrical grinders have been very successful in the industrial market. At the same time, the basic definition of cylindrical grinding is still the same, and four key measures must be taken:
1. Workpiece must be constantly rotating
2. The grinding wheel must rotate continuously
3. The grinding wheel moves forward and backward to the workpiece.
4. Move the workpiece relative to the grinding wheel.
These operations are controlled under the experienced operation of small cylindrical grinders, while for traditional models, they are usually controlled by manual operation. Today, most cylindrical grinders utilize all four movements listed above, while there are still some grinders that use only three of the four movements to grind, but still provide the expected quality.
In order to understand the subject in more depth, we first studied the cylindrical grinding method. We must understand the difference between the cylindrical grinding method and the roll grinding method. Although there are some similarities between these two, these two are different from them.
Although roller grinding is almost the same as cylindrical grinding in most processing details, there are still some critical distinctive features between the two grinding machine models. In fact, the roll grinding method was developed specifically for certain problems that usually require machines developed for such heavy tasks. In fact, these roll grinders are larger in size, heavier and stronger than small cylindrical grinders. The arrangement of the basement cases is also important for grinding stability, and these machines are not prepared for tapered work and tasks. Generally, rolls are commonly used in many industrial sectors to process products, such as paper, paint, steel, textiles and rubber materials.
In the metal processing industry, there is a huge number of grinding machine inventory. Regarding the inventory of grinding machines, there are belt grinder, bench grinder, cylindrical grinder, surface grinder, tool & cutter grinder, jig grinder, gear grinder, die grinder, angle grinder, and roll grinder. Although surface grinding is similar to cylindrical grinding in most machining details, there are some key differences between the two types. Surface grinding methods are developed specifically for certain problems that usually require a machine designed for such machining work. Therefore, compared to plain cylindrical grinders, these machines are larger in size, suitable for weight and stronger. Therefore, normally these machines have no provision for doing tapered works and missions.
In addition, the length of the rolls varies from a few centimeters up to six meters or more, and over the entire length, a highly finished surface is required. In actual use, these rolls give the sheet metal workpiece a high finish, without the need for polishing or further buffing. If the roll is designed for cold forming metal, the huge pressure between the workpiece and the roll will cause the roll to spring apart at the center. Once this happens, if a roll with a completely uniform diameter is used for this purpose, the thickness of the center of the rolled metal will become thicker and the thickness of the edges will become thinner. Therefore, it is necessary to carefully calculate the ideal and correct curve of the roller surface. When performing roller grinding, the surface with crown or convexity should be used for processing to improve accuracy. Generally, roll grinders have measures to rotate the rollers on their own bearings. All the grinding components are to be estimated properly.
Looking back at the past, it is clear that the historical traces and real time development of grinding are closely related to the development of lathes and milling machines. Because grinding has been integrated into a processing technology in modern metal processing procedures, and achieve the purpose of finishing. For the production line, it is important to have a well-developed grinding station to handle all its milled and turned workpieces, so that the following assembly, boring, or other processes can be well performed later. With regard to outer diameter grinding, OD grinding is a grinding process that occurs on the outer surface of a workpiece. The center is the end unit with a point that allows the object to rotate. Similarly, when the grinding wheel is in contact with an object, the grinding wheel also rotates in the same direction. This process effectively means that when making contact, the two surfaces will move in opposite directions, making the operation smoother and less likely to get stuck. In contrast, inside diameter grinding refers to grinding inside the object.
