Cylindrical Grinding and Great Productivity

The cylindrical grinder is one of the grinding machines used to shape the outer side of the work piece by the grinding mechanism that is universal to cylindrical work pieces.

The cylindrical grinder is one of the grinding machines used to shape the outer side of the work piece by the grinding mechanism. It can process various shapes, and the object must have at least one central axis of rotation, so that cylindrical grinding machines can rotate concentrically. This grinding inventory includes but is not limited to cylindrical shapes only, but also cam, ellipse, and crankshaft grinding, etc.


Definition of Cylindrical Grinding

The basic definition of cylindrical grinding by cylindrical grinder is that the machine must have four key roles. First, the workpiece must continuously rotate. Secondly, the grinding wheel, ie the tool, must rotate continuously. Third, the grinding wheel moves forward and backward toward the workpiece.

Finally, the cylindrical grinding machines shall move the workpiece relative to the grinding wheel. Today, most cylindrical grinding machines use these four movements, while there are still some cylindrical grinding machines that use only three of these four movements for machining.


Inventory of Cylindrical Grinding Mechanisms

There is a large inventory of grinders. Regarding the inventory of grinding machines, especially the cylindrical grinding machines, there are belt grinders, bench grinders, cylindrical grinders, surface grinders, tool, and cutter grinders, jig grinders, gear grinders, die grinders, angle grinders, and roller grinders.

Although cylindrical grinding and roll grinding is almost the same in most machining details, there are some key differences between the two. The roll grinding method was developed specifically for certain problems, which usually require the design of machines for such heavy work.

Therefore, these machines are larger in size, heavier, and stronger than plain cylindrical grinders. As a result, normally these machines have no provision for doing tapered works and tasks while these are not necessary to cylindrical grinding machines.


Roll and Cylindrical Grinding Machines

In ordinary grinding, rolls are commonly used in many industrial fields to process products, paper, paint, steel, textiles, and rubber materials. The length of the roll varies from a few centimeters to six meters or even longer, and over the entire length, a highly polished surface is required.

In actual use, these rolls can provide a high finish for sheet metal workpieces without the need for polishing or further grinding to meet the requirements. 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.

In addition, when performing roll grinding, the surface with convexity or convexity should be used for processing to improve accuracy. Generally, roller mills have measures to rotate the rollers on their own bearings. Also, they may rotate on the tailstock and headstock centers.

Taiwan’s Grinder Manufacturers

In Taiwan, PROMA Machinery, GRINDIX Industrial, PRAISE Machinery, WISE Machinery, and many other cutting-edge roller mill suppliers provide comprehensive roller grinding solutions for users worldwide.

Many of these Taiwanese grinding machine manufacturers are experienced industrial insiders who understand the application and technical issues that determine the final accuracy better than their customers. For example, the CNC Roll Grinder Machinery made by PROMA adopts FANUC CNC-controller and is applied to develop roll grinding process.


HMI Interface Helps A Lot On Grinding

The operating system of the machine is equipped with a humanized operation panel, which ensures the accurate signal of the grinding movement. The friendly human-machine interface not only ensures accurate operation but also provides great convenience for users in many different conditions of the manufacturing site.

With the help of modern programming technology, today's grinder operators only need to call the corresponding cutting program from the machine's memory, and the machine will be processed with appropriate movements.

In the 1990s, even in the early 2000s, most grinding machines were NC control systems. However, due to the increasing requirements for high-precision machining, more and more manufacturers require CNC controllers for their cylindrical grinding machines.

Although the controller system may vary from system supplier, many Taiwanese grinding machine manufacturers now provide their own CNC systems. These systems are developed by themselves and also provide users with multiple grinding modes to cover their processing tasks and can cope with the execution of multiple tasks simultaneously.

These grinding machine manufacturers do not use German or Japanese controller systems, but their HMI has been well developed in the PLC background. Once the functions need to be further changed, users can easily modify their processes in the future.
