How To Cut Acrylic Sheet With A Circular Saw

A Circular saw is a tool available for cutting acrylic sheet, if it is to cut a straight line, then use a circular saw is better.

This is very professional equipment, so we have to prepare before we start. You have to prepare:

  • Circular saw with the best circular saw blade
  • All necessary protective equipment, such as goggles
  • A few clips
  • Piece of straight wood

First of all, you have to confirm the thickness of the acrylic sheet you need to cut. The blade used to cut thin plexiglass is different from the blade used to cut thick plexiglass. For thick plates, please use a carbide tip. These blades are more durable and sharper than other blades, so they are suitable for their work. For thin slices, choose a sharp blade.

When you are sure that everything is ready, we can start.

  • You can put the acrylic board on the table and use the clamp to fix it because it can make it firm;
  • Make a mark on the part you want to cut. In order to get accurate results, please use the ruler to draw a straight line on the field and repeat the process on the other end of the acrylic sheet;
  • After that, put a piece of wood on the line you drew. This wood should be very straight. Use a clamp to fix the wood and the line together, so that it will be more stable when cutting.
  • The cutting speed should be kept slow but stable because the acrylic plate will melt when cutting at too high a speed, so the cutting speed should be at least four to three inches in one second, and this speed should not be exceeded, because if it is cut very fast When cutting glass at a speed, the edges will also crack. Therefore, if you want to get straight, smooth edges, keep the same rate throughout the process.
  • The blade should be sharp and should not be bent. If you find a bend, sharpen it or replace it with a new blade.
  • If you want to cut two or even more pieces at a time, then you also need to use coolant, because, with a large number of cutting processes, the acrylic sheet will also generate super high heat.
  • After cutting, please use 180 grit waterproof sandpaper and rub it on the cutting edge until the edge becomes smooth;
  • After softening, start polishing. Apply polish to the edges. After polishing, you will get a very beautiful gloss and the appearance will look very good.

How To Cut Acrylic Sheet With A Jigsaw

You can also cut acrylic products through a jigsaw,In fact, the basic steps are similar to the previous method. When using this tool, in order to prevent chipping, there is a technique to stick the tape on the cutting line. To prevent the saw from tilting to the left or right during straight cutting, please using the clamp-type guide. This will give you a more professional appearance. Also, don’t forget the blades: find uncoated (ie unpainted) fine-toothed sheet metal puzzle blades (for example, DeWalt’s 32 TPI). You can do some exercises on some scraps first, so let’s get started.

  1. Place the acrylic board on a flat workbench or table;
  2. Use a ruler to roughly measure the length you want to cut.
  3. Mark the cutting line with a grease pen;
  4. Paste the tape directly on the cutting line to cover the cutting line;
  5. Measure again and mark another cut line atop the painter’s tape;
  6. Snap the jigsaw’s plastic base and insert it into place;
  7. Place the blade of the jigsaw at the edge of the cutting line;
  8. Turn on the jigsaw and slowly cut the first few centimeters of the Plexiglas. After the first few centimeters, the blade will begin to heat up and will glide more easily along with the sheet; at that point, you can cut a little faster. When you near the end of the cut, grab the overhanging section of Plexiglas before it falls. Do not put your hand near the blade.

How To Cut Acrylic Sheet With A Knife

It is one of the easiest methods to cut acrylic tabletops. The process doesn’t demand to use of a power saw or any other heavy-duty electrical equipment. However, the process requires the following steps:

  • Mark the area of the sheet you want to cut.
  • Use a scoring knife to cut a narrow groove in the acrylic sheeting
  • Scoring preferably works on sheets less than ¼” (6.35mm) in thickness.
  • Place the sheet over the hard edge with groove-side up.
  • Clamp the sheet if needed.
  • Bend the overhang side of the sheet with quick and even motion.
  • As the sheet bends, the groove will deepen as the crack propagates throughout the sheet.
  • Bending will result in the separation of two pieces (polycarbonate sheet) with relatively straight and clean edges.

How To Cut Acrylic Sheet By Hand

Most people prefer to cut acrylic using a hand saw. However, this technique demands more concentration when compared with electrical saws. To achieve the best result it is advisable to use a saw that has uniform teeth.

Cutting Acrylic Sheets By CNC
