4 Must-Know Grinding Machines

Any industry or business that needs to reduce the particulate size of any given material accurately needs a top-notch grinding machine or grinder. These machines come with rotating abrasive wheels that enable experts to get rid of or cut rough surfaces from a workpiece. Grinding, in simple terms, is an essential finishing process that allows manufacturers to provide products with accurate shapes, precise dimensions, and high-quality surfaces. If your operations require the use of a grinder, consider choosing any or a combination of the following: 

1.       Die grinders

A die grinder is a handheld power tool that you can use in numerous applications, including sanding, polishing, machining, honing, and grinding materials. This machine is equipped with a spindle that rotates at high speeds and removes materials. Although manufacturers primarily design die grinders for grinding, they can do various other tasks if they have appropriate attachments, such as carbide burrs. One such job is polishing metal like stainless steel. A die grinder should be your go-to tool if your industry polishes vast metal surfaces to improve their appearance. You can also use it to smooth out final products made from wood, hardened steel, etc.

2.       Surface grinders

The main types of surface grinding machines available in the market include horizontal spindle grinders, single disc grinders, double-disc grinders, and vertical spindle grinders. These machines facilitate abrasive machining processes. Therefore, you can use them to ensure items have accurately-finished surfaces. All you have to do is place any abrasives on the corners and exterior of the grinding wheel and fire up the surface grinder. It will effectively grind down the metal surface until it's perfectly level and flat.

3.       Centerless grinders

Choose a centerless grinding tool if you want to work on any workpiece with a significantly intricate shape. As the name suggests, these machines have no fixed center, meaning they don't need fixtures designed to hold the workpiece in a fixed position. There are two types of centerless grinders popular in most industries today: thru-feed and in-feed machines. A thru-feed grinding machine is ideal for tubular workpieces of any size. On the other hand, in-feed grinders can effectively work on workpieces with unusual or complex shapes. For instance, you can apply in-feed grinding when working on a component with a portion that's larger or smaller than another.

4.       Cylindrical grinders

Cylindrical grinders work on an object's outer surface like other grinding machines. But, although these tools can grind items with different shapes, they must come with central rotation axes. That means they are suitable for cylindrical, crankshaft, cam, and ellipse shapes. When using these grinding tools, expect the cylinder to rest between two predetermined centers and rotate in a specific direction. In addition, the grinding wheel(s) will approach and turn in a direction opposite to that of the rotating cylinder.
