Tool Grinder

Tool grinding is considered very economic in the manufacturing sites for the recycling of the cutters and tools. In the machine tool and other machinery industry, tool grinding is a must have for all the manufacturing sites due to the cutting accuracy and processing repeatability. There are many kinds of tool grinders in the industrial market. Each of them performs different advantageous within different models. Let’s take a look of some famous models in the industry.

Multiple Axis Tool Grinder

5 axis tool grinder refers to the design that there are five axis installed onto the tool grinders that can grind tools with a specific axis design in the tool grinding industry.  It is the condition that recognizes the machine as a 5 axis grinder in the tool grinding category. The design contains five movable axis at the same time that can coordinate with synchronized works. The structure is similar with the de-burring process in some extend if one consider the working mechanisms. Furthermore, besides the five axis model, there is six axis as well, which are also tool and cutter grinders that can grind tools with its specific axis design. It is recognized as a great help with its additional one axis compared to the five axes. With another movable working track for the grinding process, things are easier to do. 

In the metal working process, tool grinding processes are sometimes similar to de-burring, as metal burrs are raised edge or small pieces of materials that remains attached to a work piece after a modification process, and such conditions are not ideal to the performance of the work pieces. As a result, the mechanism of removing those un-wanted edges is considered very important for the following process, and it is usually an unwanted piece of materials and is removed with a de-burring tool at first and later by the machine in a process called de-burring procedure.


Essence of Tool Sharpening

The tool and cutter sharpening of working tools is a big thing, which is more economic and environmental friendly. Since the disposable cutter may cause more trashes that lead to unwanted industrial wastes, the reason for re-sharpening the existing tools is obvious, and the essential definition of grinding is that, this is one of the power tools or machine tools which are utilized, and is a type of machining using an abrasive grinding wheel as the cutting tool for the processing of other processing tools. During the cutter sharpening, each grain of the abrasive on the wheel's surface cuts a small chip from the work piece through shear deformation.

Consider the surface grinders and cylindrical grinders, the works of grinding is adopted to refine the work pieces that are useful to show high surface quality and high accuracy of shape and dimensions. However, because the accuracy in dimensions in grinding is generally of the order standard of 0.000025 mm, in most applications, it tends to be a finishing operation and removes comparatively little metal. This is about 0.25 to 0.50 mm depth as the standard scale. Furthermore, there are a few of classifications of those grinding methods to be discussed with, and we will take a look of them in the present article.


Belt Grinding

The belt grinding is an abrasive machining process and people use them on metals and other materials as well. This is typically utilized as a finishing process in the industry in which an industrial belt is coated in abrasive material and is run over the surface to be processed in order to remove materials or produce the desired finish. The idea of wide belt grinding is a familiar process in the industry as well as home applications. There are several basic methods introduced here for belt grinding category. They are stroke belt, platen belt, wide belt, back-stand (pressure), Portable (manual), and Centre-less method respectively. Generally speaking, grinding head, regulating head, and work rest support are three fundamental elements of the belt grinding.

For these three components, they are distinguished from all the other methods. But in regular condition, the work pieces are pressed in between the grinding head and the rest support unit. The objective of the regulating head is to coordinate the belt pressure as planned.


Tool Grinding Applications

The grinding of tools and cutters vary in the industry. The work pieces may be sawing blades, milling tools, turning tools, boring tools, or many other cutting based tools. For instance, in the example of sawing blades, no matter it is a circular saw or a band saw, all the sawing materials will eventually come to wear out due to the constant contact. After a longer period of uses, those sawing blades or discs will need to be re-sharpened in order to be reused again in the manufacturing plant for constant quality performance. This situation, i.e. re-sharpening the tools, is the same with the turning tools, even though many onsite operators use disposable cutter pieces now, there are still many traditional uses of lengthy steel cutters that need to be re-sharpened after machining. The existence of the tool cutter is a must have for all the manufacturing sites in the world. Their existence can help manufacturers to save both expenses and resources, and at the same time, sharpen their operators’ professional skills.
