Punch Grinder

In the punch grinding process, some of the procedures begin with high speed grinding, which loads data first, and then is the rough relief grinding process. During the operation, there may be intermittent heavy sparks emitted from the work piece due to the grinding actions. After the wheel head moves to a safe position, then it is necessary to do a series of safety checks and protocols. After that, the machine will start to finish in less than a few minutes. Punch grinding machines are very custom based and industrial users may have to contact suppliers for detail and profound consultation about the machine specifications as well as the future applications across the variables. For industrial machining, grinding is one of the most important links in the whole process. After forming, cutting, and other complex processing, many work pieces would go to this step for further finishing. The process of 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 (grinding wheel) that cuts chips of metallic or nonmetallic substance from a work piece, rendering a flat or smooth face.

Grinding mechanism

Here let’s talk about the essence of grinding and grinders. Within industrial machining, grinding is one of the most important links in the whole process. After forming, cutting, and other complex processing, many work pieces would go to this step for further finishing. The process of 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 (grinding wheel) that cuts chips of metallic or nonmetallic substance from a work piece, rendering a flat or smooth face.
 
There are several types of grinding mechanisms and grinder models, and among all the grinding processes, surface grinding is the one of the most general one of the various grinding operations. CNC 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 computer numerical control mechanism that is driven by programmed processes. 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 CNC vertical grinders are composed of an abrasive wheel, a controller, a work piece holding device, and a reciprocating table. During machining, the holding device holds the material in place while it is being machined. The clamping mechanism can be done via two methods: one is for the ferromagnetic pieces, which are held in place by a magnetic chuck, while for the non-ferromagnetic and nonmetallic pieces, they are held in place by either vacuum or mechanical means. The clamping mechanism is crucial to the whole processing.
 
Besides the clamping force and clamping parts, critical factors that affect grinding are the material of the grinding wheels and the material of the work pieces. Typically, work piece materials include aluminum, brass, steel, cast iron, and mild steel. Some of them are more stable and will not attach to the wheel during processing, while some are with different physical natures that would lead to corrosion that is not ideal for further application. On the other hand, speaking of the shape of the grinding wheel, the shape is not confined to specific shapes but could be a variety of shapes. Onsite operators can dress the wheels for specific usages and purposes. There is one thing that is noteworthy that, during surface grinding, the wheel shape will be affected to the reverse shape of the work piece, so that operators have to be aware of the change of the shapes in order to instant modifications onto the grinding wheels so that the desired grinding could be continued. Since all the grinders are machine tools utilized to provide precision ground surfaces and the purpose could be of specific size or for the surface finishing, the typical accuracy of a grinding machine depends on the types and usages, however a certain accuracy values should be achievable on most surface grinding machine models.

 

Punch grinding

Back to the topic of this article about the process of punch grinding, and we would see that typically in the punch grinding mechanism, some procedures begin with high speed grinding of the work piece as the first step, and then data loading is undergoing, and after that, it is the rough relief grinding process for the work piece. During this operation, there may be intermittent sparks emitted apparently from the work piece due to the grinding process. Later, after the wheel head moves to a safe position, then it is necessary to do a series of safety checks and protocols. Many punch grinding machines are controlled by CNC programmed system, and the punch grinding machine will start to finish in less than a few minutes. As we have said that since punch grinding machines are very purpose-based grinding and industrial users may have to contact suppliers for detail and profound consultation, it is very likely that most punch grinding machines in the production lines we have seen are under a certain level of custom made process.
