How to Resharpen Cutting Tools for Extended Life and Improved Performance

Resharpening is a process of re-sharpening a dull or worn out cutting tool by grinding it to restore its original shape and sharpness. This process can be done using various types of grinding machines, such as a bench grinder, a cylindrical grinder, or a surface grinder.

The goal of resharpening is to extend the life of the cutting tool, improve its performance, and reduce the need for frequent replacements. It can also help to reduce costs associated with purchasing new tools and improve productivity by reducing downtime for tool changes.

Resharpening can be done on a variety of cutting tools, including drill bits, saw blades, milling cutters, and lathe tools. The process typically involves the following steps:

1. Inspection: The cutting tool is inspected to determine its condition and identify any damage or wear.
2. Cleaning: The tool is cleaned to remove any debris or contaminants that may interfere with the grinding process.
3. Measurement: The tool is measured to determine its original dimensions and shape, and to ensure that it is properly aligned for grinding.
4. Grinding: The tool is ground using a grinding wheel or a diamond wheel to restore its original shape and sharpness. The grinding process may involve multiple passes, depending on the severity of the wear and the desired level of sharpness.
5. Polishing: After grinding, the tool may be polished to remove any scratches or imperfections and to improve its surface finish.
6. Testing: The tool is tested to ensure that it is properly sharpened and functioning as expected.

Overall, resharpening is a cost-effective and efficient way to extend the life of cutting tools and improve their performance. It can help to reduce waste, improve productivity, and increase profitability in a variety of industries, including manufacturing, construction, and woodworking.
