CNC Profile Grinder GuideCNC profile grinder is the grinding machine that can do profile grinding with the guide of CNC programs. Regarding the working mechanism, it is much like angular grinding or angular cylindrical grinding. In the subsidiary sector of grinding machines in the machine tool industry, the design of angular cylindrical grinding eliminates contact friction between metal materials without the need to replace parts. For an angular cylindrical grinder to work well, the spindle has to be rigid, accurate, and with lower vibration and heat growth.
Many angular cylindrical grinding machine manufacturers design their machines in custom model, and the close-Loop Linear Motor CNC profile grinder and electronic system producing equipment are also developed under rigid standards. Generally, a cylindrical grinding machine is one of the grinding machines that are used to shape the outer side of work pieces through the grinding mechanism.
The Essence of Cylindrical Profiling
Cylindrical grinding machines can process a variety of shapes. The object must have at least a central axis of rotation so that it can be spinning concentrically. This includes but is not limited to such shapes as cylindrical, but from such as cam, ellipse, crankshaft, etc. Now grinding machines are used in many processing procedures in order to further perfect the final quality of the work pieces.
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 machine.
Cylindrical grinding is different from other grinding mechanisms. To compare with other similar models such as roll grinding, it is obvious that even though roll grinding is nearly the same as cylindrical grinding in most 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 processing missions. Furthermore, 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 cylindrical grinding is similar to roll and surface grinding, the categorization separates them respectively. There are some critical differences between these categories. For instance, surface grinding method is developed specifically for certain issues that usually require machines that are designed for such machining works.
Grinding of Work Piece Surfaces
Surface grinding is one of the most important parts in the whole finishing process. After forming, cutting, and other complex processing, many work pieces would go to this step for further finishing. The process of surface grinding is used to produce a smooth finished surface on either flat or other specific surfaces. It is a widely used abrasive machining process by which a spinning wheel is covered in rough particles that cuts chips of metallic or nonmetallic substance from a work piece, rendering a flat or smooth face.
Among all the grinding processes, surface grinding is the one of the most general one of the various grinding operations. CNC surface grinding is a finishing process which utilizes a rotational abrasive wheel to smooth the surface of metallic or non-metallic materials in order to deliver a refined physical situation by removing the layer and impurities on the work piece surfaces under the control of programmed cutting routes that is driven by professional grinding systems. Therefore, these processes will attain a desired surface for functional purposes that are planned and programmed by engineers. Regarding the mechanical composition, the mechanical structure of surface grinders are composed of an abrasive wheel, a work piece holding device, and a reciprocating table.
The works of profile grinding is complicated and the process is often long. Those working steps programmed with the CNC work efficiently with the complex machining and make those steps integrated into one. It is expected that with the demands for complex processing grows, there will be more and more diversified profile processing machines developed for the market demands.
