Understanding the Basics of Sharpening with an Angle Grinder
Sharpening tools with an angle grinder is a straightforward process commonly used by DIY enthusiasts and professionals alike. It involves grinding a metal surface at an angle using an abrasive wheel to achieve a sharp edge. However, to get a clean and razor-sharp cutting edge, you need to understand the angle, grit size, and wheel type, among other factors.
Choosing the Right Angle Grinder
The first step in sharpening tools using an angle grinder is selecting the right grinder for the job. Typically, you should choose an angle grinder with adjustable speeds since different tools require varying speeds for optimal sharpening. Likewise, selecting the right wheel diameter is crucial, with larger diameters being better suited for larger tools.
Preparing the Grinder and Tools
Before getting started, ensure that your angle grinder and tools are suitably prepared. This involves attaching the appropriate grinding wheel, adjusting the guard to protect yourself against flying debris, and wearing protective gear such as goggles, gloves, and a dust mask. You should also clean the tool’s surface to avoid any grit or debris compromising the sharpening process.
Sharpening the Tools
The sharpening process involves positioning the angle grinder’s abrasive wheel at the correct angle and grinding the tool’s cutting edge against it. Start with a coarse grit wheel to remove any sharpened or damaged parts, then switch to a finer grit wheel for a smoother finish. Depending on the tool and the type of edge you want to achieve, you may need to reposition the angle grinder or adjust the grinding angle several times to get the desired sharpness.
Cleaning and Maintenance
After sharpening the tools, it’s essential to clean them thoroughly to remove any grit, oil, or debris. This will prevent any cross-contamination when using the tools, eliminate any risks of rust, and prolong the tool’s lifespan. Additionally, you should maintain your tools regularly by sharpening them periodically, storing them in appropriate conditions, and verifying their sharpness before use.
