Cylindrical Grinding Machines

To be specific, the essential definition of cylindrical grinding is that the machine must have four critical actions: Firstly the work piece must be constantly rotating; secondly, the grinding wheel, i.e. cutter, must be rotating constantly; thirdly, the grinding wheel is fed forwards and backwards towards the work piece. Last, work pieces are traversed with respect to the grinding wheel. The majority of cylindrical grinders nowadays utilize all the four movements, while there are still grinders that only utilize three of the four actions to process. To compare with other similar model, even though roll grinding is nearly the same as cylindrical grinding in most of the processing details, there are some critical differences between the two categories. 

In fact, 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.

Comparison

To compare with other similar model, even though roll grinding is nearly the same as cylindrical grinding in most of the processing details, there are some critical differences between the two categories. In fact, 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. There is 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.

That is to say, although surface grinding is similar as cylindrical grinding in most of the processing details, there are some critical differences between the two categories. The surface grinding method is developed specifically for certain issues that usually require machines that are designed for such machining works. Therefore, these machines are larger in size, appropriate 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.

What are the differences?

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. First of all, roll grinding method is developed specifically for certain issues that usually require machines that are structured for such heavy duty works. Accordingly, 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.

Applications

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. In addition, 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.

Grinding methodology

In fact, the development of grinding goes with the development of lathe and milling machines as grinding is integrated as one of the machining process in the modern metalworking procedure, achieving the finishing part. It is important for a production line to have a well developed grinding station to deal with all their milled and turned work pieces so that the following assembly, boring, or other process can be well done afterwards.

Regarding the outside dia. Grinding, the (OD grinding) is a grinding process occurring on external surface. The centers are end units with a point that allow the object to be rotated. Similarly, the grinding wheel is also being rotated in the same direction when it comes in contact with the object. This process effectively means the two surfaces will be moving opposite directions when contact is made, and that allows for a smoother operation and less chance of a jam up.

On the contrary, inside diameter grinding is the grinding occurs on the inside of an object. The grinding wheel is always smaller than the width of the hole being ground. In this case, the object is held in place by a collet, which also rotates the object in place. Just like the OD grinding, the grinding wheel and the object rotated in opposite directions giving reversed direction contact of the two surfaces where the grinding occurs.
