An OD grinder machine, also known as an “outside diameter grinder” or “cylindrical grinder,” is a type of machine tool used for precision grinding of cylindrical or circular workpieces. It is typically used to grind the external surface of a workpiece to achieve high dimensional accuracy and surface finish.

OD grinder machines are commonly used in manufacturing, machining, and metalworking industries for a variety of applications, such as grinding cylindrical shafts, rods, spindles, bearings, and other precision components. They can be operated manually, semi-automatically, or fully automatically, depending on the level of automation and complexity of the machine.

OD grinder machines typically consist of a wheelhead, which holds and rotates the grinding wheel, a workhead, which holds and rotates the workpiece, and a tailstock, which supports the workpiece during grinding. The grinding wheel removes material from the workpiece as it rotates, and the workpiece is moved longitudinally against the rotating wheel to achieve the desired shape and size.

OD grinder machines come in various configurations, including plain cylindrical grinders, which have a fixed wheelhead and a movable workhead, and universal cylindrical grinders, which have both a swiveling wheelhead and workhead, allowing for greater flexibility in grinding different types of workpieces. OD grinder machines may also include additional features such as automatic in-process gauging, CNC controls for precise positioning and grinding, and various attachments for specific grinding applications.

Overall, OD grinder machines are widely used in the manufacturing industry for achieving precise and high-quality cylindrical grinding of workpieces, making them an essential tool for many machining operations.
