Used Grinders

Grinders or grinding machines are used for achieving tight dimensional tolerances and high-quality finishes on metal parts. These finishes are made by the use of an abrasive wheel grinding against a workpiece. Due to the wide variance in part designs, there is a variety of grinders utilized for finishing parts. These include but are not limited to cylindrical grinders, centerless grinders, profile grinders, and surface grinders. Our company buys and sells all of these used grinders from such brands as Blanchard, Okamoto, and Harig.

    Different Type of Grinders Used in Metalworking

    Metalworking grinding machines are tools that are used to shape and finish metal materials. These machines come in various forms and designs, each with its own unique set of capabilities and features. Some of the most commonly used types of metalworking grinding machines include surface grinders, cylindrical grinders, centerless grinders, and internal grinders.

    What Are Surface Grinders?

    Surface grinders are used to grind flat surfaces. They consist of a rotating grinding wheel, a work table, and a device that holds the workpiece in place. These machines are typically used to remove small amounts of material from a workpiece, such as removing rust or preparing a surface for painting. Surface grinders are also commonly used to grind flat surfaces on machine parts, such as gears and shafts.

    How a Cylindrical Grinder Works

    Cylindrical grinders are used to grind the outside or inside of cylindrical shapes, such as shafts, rods, and cylinders. These machines consist of a rotating grinding wheel, a work table, and a device that holds the workpiece in place. Cylindrical grinders can also be used to grind the inside of a hole, such as grinding the bore of a bearing race.

    Uses of Centerless Grinders

    Centerless grinders are used to grind cylindrical parts that do not have a central axis of rotation. These machines consist of a rotating grinding wheel, a work table, and a device that holds the workpiece in place. Centerless grinders are commonly used to grind cylindrical parts that have been turned on a lathe, such as bearings, bushings, and shafts.

    How Internal Grinders Work

    Internal grinders are used to grind the inside of a cylindrical shape, such as the bore of a bearing race or the inside of a pipe. These machines consist of a rotating grinding wheel, a work table, and a device that holds the workpiece in place. Internal grinders can also be used to grind the inside of a hole, such as the bore of a valve or the inside of a pipe.

    Additional Grinders in the Metalworking Industry

    In addition to these types of machines, there are also specialized grinding machines, such as tool and cutter grinders and jig grinders. Tool and cutter grinders are used to sharpen and grind the cutting edges of tools, such as drill bits, milling cutters, and reamers. Jig grinders are used to grind complex shapes and precision holes, such as those found in jigs and fixtures.

    All of these metalworking grinding machines are powered by a motor that rotates the grinding wheel. The speed of the motor can be adjusted to suit the material being worked on and the type of grinding being done. Some machines also have a cooling system to keep the workpiece and the grinding wheel cool during the grinding process.

    In summary, metalworking grinding machines come in various forms and designs, each with its own unique set of capabilities and features. Surface grinders, cylindrical grinders, centerless grinders, and internal grinders are some of the most commonly used types of metalworking grinding machines. Additionally, there are specialized grinding machines, such as tool and cutter grinders and jig grinders. All of these machines are powered by a motor that rotates the grinding wheel and have a cooling system to keep the workpiece and the grinding wheel cool during the grinding process.
