Grinding is an essential process for many industries for various reasons. First, it allows manufacturers to produce items with quality surface finishes. Experts also use it to shape products accurately and guarantee precise dimensions. And, unlike conventional machining, this technique ensures experts enjoy longer tool life and enables you to work on difficult-to-machine materials like carbide-impregnated metal alloys. If your company heavily relies on grinding and you need an effective and efficient technique, try outside diameter (OD) grinding. Here's all you need to know about this method:
1. Done in simple steps
As the name suggests, outside diameter grinding involves working on and removing material from a particular item's external surface. It's one of the primary cylindrical grinding techniques. Therefore, when using this grinding method, you'll work with a constantly rotating workpiece and grinding wheel. The workpiece should rest between two centers and turn opposite to the grinding wheel. You can use outside diameter grinding to grind rods and cylinders, among other items with cylindrical surfaces.
2. It demands special equipment
Outside diameter grinding requires you to use a cylindrical grinder. This machine uses various parts to shape an object, including the grinding wheel, headstock, chuck, and foot stock. The grinding wheel comes with abrasive grains and layers of rigid materials like fiberglass. Technicians design it to remove materials from the workpiece, consequently refining and shaping it. On the other hand, the headstock houses the motor that drives the object undergoing grinding. Quality equipment also comes with a chuck installed to hold the workpiece in place and a supporting foot-stock you can use to adjust the equipment's ability to hold objects of different lengths or sizes.
3. It's ideal for a variety of materials
One of the advantages of using OD grinding machines is that they let you work on different materials, the most suitable being mild steel and cast iron. These are commonly used materials in most industries because they are stronger than alternatives like aluminum. That means products or components made from them withstand higher internal pressures when installed in car engines, etc. Although outside diameter grinding works best on metal items and surfaces, you may apply it effectively on other materials, including plastic and ceramics.
4. You can use it to fix imperfections
Manufacturing processes are fraught with issues like faulty machines and unskilled workers, which often facilitate the production of defective items. Fortunately, if your industry produces metallic and non-metallic objects with cylindrical shapes, you can use an outside diameter grinding machine to fix this problem. That is so because the grinding wheel on OD grinders is designed to make exterior surfaces smoother and more rounded. Therefore, if you have a slightly oval-shaped item that needs to be rounder, OD grinding will help you remedy the situation.
