Centerless grinders are one of the newest forms of metalworking technology and have rapidly become popular with hobbyists, professionals, and the “do it yourself guy”. They are a more cost-effective alternative to traditional milling machines. They offer several advantages over older designs such as the hammer drill press and bench mounted lathes. They also allow for precision and accuracy unlike many other types of machinery. One thing they lack however is the safety aspect that the older machines are known for. In this article we’ll take a look at what makes them safer to use and some considerations before using them.
The most important advantage of a centerless grinder compared to other types of milling machines is their speed and the quality of the grinding product it produces. By designing the frame of this type of machine with high rigidity, they are capable of achieving speeds far in excess of 300 revolutions per minute. This is close to the world record for high speed grinding. In addition, because the bearings are so tightly spaced, the grinding wheel doesn’t have to work as long.
Centerless grinder designs are sometimes utilized in applications where greater fatigue tolerance is required. An application example would be an auto body shop or automotive shop that needs to create auto panels that are heavy weight and strong. Because the bearing centers are so tightly spaced, the grinding wheel can only work at a maximum rate of about two hundred revolutions per minute, well within the tolerances needed. This application example is the perfect choice for the centerless grinder because the fatigue tolerance is high and the precision and accuracy are exceptional.
Centerless grinders can also be used in situations where high accuracy and/or precision are required. This type of machine is often utilized to build components that are heavy enough such as tubes, valves, rings, nuts, bolts and many others. The large roundness of the components prevents the machine from working properly if the roundness is not maintained at its highest potential.
The in-feed grinding wheel and the centerless grinder are both designed with high quality output devices. Both machines have excellent output capabilities because the workplace, or bearing assembly, is able to withstand large fatigue loads. These types of bearing designs also allow for the high accuracy that is necessary in these applications. The in-feed grinders are normally used to cut soft metals; however they are capable of cutting more difficult metals such as steel when the workplace is fastened at a right angle. Also, both the in-feed and the centerless grinder are designed with high performance output capabilities and superb finishing capabilities.
The above application examples clearly demonstrate the superiority of the centerless grinder. The machine is the perfect choice for high quality precision machining applications. It can cut through all types of material with high accuracy and it delivers exceptional finishing capability. The grinding capability of the centerless grinder is therefore very high and it will cut through all types of materials at its maximum potential. Moreover, both the in-feed and the centerless grinders are perfect for use in all kinds of automotive applications including automotive stamping, cooling towers, automotive door faces, automotive fasteners, spring packs, timing and electronic components.
