Lexan sheet, also known as polycarbonate sheet, is an incredibly versatile material that is renowned for its exceptional transparency and impact resistance. Its applications span a wide range of industries, from construction and glazing to automotive and aerospace. However, cutting Lexan sheet can be a daunting task if you don’t have the right tools and knowledge. In this comprehensive guide, we will explore the various methods for cutting Lexan sheet, providing detailed instructions and tips to help you achieve precise and clean cuts.
The most common method for cutting Lexan sheet is using a circular saw. This method is ideal for straight cuts and can be used to cut through thick sheets of Lexan. When using a circular saw, it is important to use a fine-toothed blade designed specifically for cutting plastic. Additionally, it is essential to clamp the Lexan sheet securely to prevent it from moving during the cutting process. It is a convenient and efficient method if you have a circular saw and the appropriate blade. However, it is worth noting that circular saws can generate dust and noise, so it is crucial to wear proper safety gear, including a dust mask and hearing protection.
Another method for cutting Lexan sheet is using a jigsaw. A jigsaw provides more flexibility than a circular saw and is better suited for intricate cuts or cutting curves. Similar to using a circular saw, it is important to use a blade specifically designed for cutting plastic. Additionally, it is essential to support the Lexan sheet adequately to prevent it from flexing or vibrating during the cutting process. Jigsaws offer greater precision and versatility compared to circular saws, making them a preferred choice for complex cuts. However, they can be slower and require more control during operation.
Sanding and Finishing the Edges
Once you have cut your Lexan sheet, you will need to sand and finish the edges to remove any sharp or rough edges. This will help to prevent the edges from becoming damaged and will also give the Lexan sheet a more finished look.
Sanding
To sand the edges of the Lexan sheet, you can use a sanding block or sandpaper. Start with a coarse grit sandpaper and gradually work your way down to a finer grit until the edges are smooth and free of any sharp edges.
Finishing
After you have sanded the edges of the Lexan sheet, you can finish them by applying a clear sealant. This will help to protect the edges from the elements and will also give them a glossy finish.
Additional Tips for Sanding and Finishing Lexan Sheet Edges
Here are a few additional tips for sanding and finishing the edges of Lexan sheet:
- Use a sharp blade when cutting the Lexan sheet. This will help to create a clean cut and will minimize the amount of sanding that is required.
- Wear safety glasses and a dust mask when sanding the Lexan sheet. This will help to protect your eyes and lungs from the dust that is created.
- Use a light touch when sanding the Lexan sheet. Applying too much pressure can damage the material.
- Allow the sealant to dry completely before handling the Lexan sheet.
| Sandpaper Grit | Use |
|---|---|
| Coarse (80-120) | For removing large burrs and imperfections |
| Medium (150-220) | For smoothing the edges and removing smaller burrs |
| Fine (240-320) | For polishing the edges and removing any remaining scratches |

How to Cut Lexan Sheet
Lexan is a polycarbonate thermoplastic that is known for its strength, durability, and clarity. It is often used as a replacement for glass in a variety of applications, such as windows, skylights, and machine guards. Lexan can be cut using a variety of methods, including sawing, drilling, and water jet cutting.
Sawing
Lexan can be sawed using a variety of saws, including circular saws, jigsaws, and band saws. When sawing Lexan, it is important to use a sharp blade and to cut slowly and carefully. Lexan can be difficult to cut, so it is important to be patient and to take your time.
Drilling
Lexan can be drilled using a variety of drill bits, including twist drills, spade bits, and hole saws. When drilling Lexan, it is important to use a slow speed and to apply light pressure. Lexan can be brittle, so it is important to avoid over-drilling.
Water Jet Cutting
Water jet cutting is a process that uses a high-pressure stream of water to cut through materials. Water jet cutting is a precise and efficient way to cut Lexan. However, water jet cutting can be expensive, so it is important to weigh the cost of water jet cutting against the cost of other cutting methods.
