Blade coating: Some blades come with special coatings, such as Teflon or anti-friction coatings, which can help reduce heat and friction during the cutting process. These coatings can prevent the plexiglass from melting or sticking to the blade, resulting in cleaner cuts.
Manufacturer’s recommendations: It’s always a good idea to consult the manufacturer’s recommendations for blade selection. They may have specific recommendations based on their product’s characteristics and the intended use.
Remember to always prioritize safety when working with power tools. Wear appropriate safety gear, such as safety glasses and gloves, and follow all safety guidelines provided by the manufacturer.
Adjusting the table saw
Before cutting plexiglass with a table saw, it is important to properly adjust the saw to ensure clean and accurate cuts. Here are the steps to adjust the table saw:
- Check the alignment: Start by checking the alignment of the table saw blade and the fence. The blade should be parallel to the fence to avoid any binding or kickback. Use a measuring tool, such as a dial indicator or a specialized alignment jig, to check the parallelism.
- Adjust the fence: If the fence is not parallel to the blade, it needs to be adjusted. Most table saws have adjustment screws or knobs that can be used to align the fence. Loosen the screws or knobs, make the necessary adjustments, and tighten them back to secure the fence in the correct position.
- Set the blade height: The height of the blade should be set according to the thickness of the plexiglass being cut. It is recommended to raise the blade only slightly above the thickness of the plexiglass to minimize the risk of chipping or cracking.
- Install a zero-clearance insert: For cleaner cuts, consider installing a zero-clearance insert on the table saw. This insert reduces the gap between the blade and the table surface, providing more support to the plexiglass and reducing the chance of tear-out.
- Use a push stick: When cutting plexiglass on a table saw, it is crucial to use a push stick or push block to maintain a safe distance from the blade. This will help prevent accidents and keep your hands away from the spinning blade.
