CNC Roll grinder
A grinder is a powered tool or machine tool that used for grinding process, which is a common type of machining that utilizes abrasive wheel or wheels as the cutting means for processing. Each grain of abrasive on the wheel's surface cuts a small chip from the work pieces through shear deformation method.
There are a huge number of grinding machine inventory. Regarding the grinder inventory, there are belt grinder, bench grinder, cylindrical grinder, surface grinder, tool & cutter grinder, jig grinder, gear grinder, die grinder, angle grinder, and roll grinder, just to name a few.
To be specific, although roll grinding is nearly the same as cylindrical grinding in most of the processing details, there are some critical differences between the two categories. Roll grinding method is developed specifically for certain issues that usually require machines that are designed for such heavy works. Therefore, these machines are larger in size, heavier in weight, and are more rigid if compared with plain cylindrical grinders. As a result, normally these machines have no provision for doing tapered works and tasks.
Usually, rolls are commonly used in many industrial sectors for processing products, for paper, paint, steel, textiles, and rubber material processing. The length of the rolls varies from a few centimeters up to six meters or more, and throughout the length, a highly finished surface is required. In practical usages, these rolls give sheet metal work pieces the high finish, which is required without polishing or further buffing. If the rolls are designed to be used for cold-forming metal, then the great pressure between the work and the rolls would cause the rolls to spring apart at the center. Once if such situation occurred, the rolled metal would be thicker at the center while thinner at the edges if the perfectly uniform diameter rolls were used for this purpose. Therefore, the desirable correct curve of the face of the roll needs to be carefully calculated. In addition, when it comes to roll grinding, machines should occur with a crown or convex surface for precision. Usually roll grinders would have provisions for rotating the rolls on their own bearings. And, they may also rotate on the tailstock and headstock centers.
In Taiwan, there are many cutting edge roll grinding machine suppliers that offers a comprehensive roll grinding solutions to users all over the world, such as PROMA Machinery, GRINDIX Industrial, PRAISE Machinery, WISE Machinery, etc. Many of these Taiwanese grinding machine manufacturers are experienced industrial insiders who know better than their customers about the application and the technical issues that determine the final precision. For example, the CNC Roll Grinder Machinery made by PROMA adopts FANUC CNC-controller and is applied to develop roll grinding process. The operation system of this machine is configured with a humanized operation panel that promises accurate signaling of grinding motions. The friendly human machine interface not only assures precision operation, but also great convenience for users in the manufacturing sites of many different conditions. With modern programming technology, operators of grinders nowadays only need to call the corresponding cutting programs from the machine memory and the machine will process with appropriate motions.
