1. The method is to put the ruler on the plate to be cut and fold it: This is a straight-line cutting method for acrylic. The edge of the ruler coincides with the cutting line, and the ruler is fixed. Drag and draw along the edge of the ruler with a hook knife, and a thin groove will be drawn at the place where the sheet is to be cut. When the depth of the thin groove is about half the thickness, you can move the sheet to make the thin groove drawn by the hook and The edges of the table coincide, one hand presses the plate inside the table, and the other hand holds the plate outside the table, pressing down quickly with the palm. The acrylic will snap off neatly from the hooked position.
2. The cutting route can be straight and flexible. There are special vibration saws, saws: use a saw to cut materials or shape. For micro saws, hacksaws and wire saws can also be used. When using a saw to process acrylic, you should try to make the sawdust fall off, because the sawdust will melt on the friction-heated saw blade and stick to the saw teeth, which will make the saw teeth useless. You can slow it down to prevent the saw blade from overheating and sticking to the sawdust or brush Go to the sawdust. Because the edge of the sawn material is rough, it must be smoothed with a file and sandpaper. Common data for cutting pipes and bars.
3. There are the following three situations that need to be filed: 1 saw the edge of the data. 2 The rough embryo made is slightly larger but convenient for sawing. File: The file is filed with a file. Use a file to match the required size. 3 Remove the sharp edges and corners to make it smooth and feel good.
4. Is there a special vibration saw, hot cutting: If the cutting route is curved and complicated. It can be cut with a hot cutting saw, but pay attention to the thickening and uneven edges of the acrylic cut with the hot cutting saw, so the hot cutting can only be rough embryos, which should be hot cut outside the waste specification line to leave room for fine processing , Otherwise it will be smaller than the required size after fine processing.
5. Put the material to be folded on the hot bender and bake it softly. Hot bending: If you want to bend the plate to a certain angle. For example, to bend at a right angle. A hot bender is necessary. Then bend it on the edge of the table, and the angle will be fixed after cooling.
6. Cutting with a lathe can ensure that the cross section is perpendicular to the axis. Cutting: Acrylic can also be cut with a lathe like copper, aluminum and other metals. For example, it is required to accurately cut a section of plexiglass or plexiglass tube. And the size is more accurate. Another example is the use of lathes to process workpieces such as small pulleys, cones, and truncated cones from bars. It is necessary to pay attention to the cutting debris at any time with a brush to avoid friction between other tools and materials sticking to the tools, affecting the speed and quality of processing.
7. Wrapped drill bit, drilling: drilling on acrylic is more troublesome than drilling on metal and wooden materials.
It mainly lies in the following two aspects: 1. The heat generated by the friction between the drill bit and the acrylic makes the drill cuttings melt and stick to the drill bit. No good holes can be drilled. 2. When the hole is about to be drilled, the drill bit will drive the data to rotate together, especially when the drill bit with a diameter of 4 mm or more is used to drill the plate. If you are not careful, you will hurt your hand. Pay attention to the following points during operation: ①It is better to wear gloves on your left hand to prevent the data from rotating and hurt your hand. ②First, drill small holes with a small drill, such as a drill with a diameter of 23 mm, to ensure that the position of the hole is accurate. ③Using intermittent drilling, that is, operating the drill rod to drill the bit and then immediately raise the bit to cool down, so as to prevent the bit from overheating and melting the drill chips. ④Remove drill chips with a brush. ⑤When the hole is about to be drilled, the depth of each drilling should be small to prevent the drill from driving the data to rotate together. ⑥Choose a drill of the right size. Sometimes it is necessary to drive a metal rod into an acrylic hole, and it is required to be stable, the diameter of the hole should be 0.10.2 mm smaller than the diameter of the metal rod. If the metal rod is to be flexibly rotated in the hole, the diameter of the hole should be 0.10.2 mm larger than the diameter of the metal rod.
8. You must first drill a screw in acrylic that is slightly smaller than the screw (smaller 1/102/10 screw, the bigger the screw, tapping: tapping is to open the thread on the material. Sometimes I want to screw the screw into the plexiglass. Less The more) holes, and then use the corresponding taps (tools for screw threading, available in the tool store) to screw into the holes, the holes will have threads. For example, to make a hole for screwing a screw with a diameter of 5 cm, first Use a drill with a diameter of 4 cm to make a hole, fix the M5 tap on the tap holder, screw the tap into the hole, and tap the thread.
9. Therefore, the mutual bonding between plexiglass does not require other adhesives, bonding: because acrylic is soluble in chloroform. Just use a small syringe (usually 5ml to suck a small amount of chloroform liquid, gently and evenly squeeze the chloroform onto the surface of the plexiglass to be bonded, immediately press the bonding area, and wait for the liquid to evaporate, the plexiglass Just stick it together. Pay attention to the appropriate amount of chloroform. If it is too small, the bonding area is too small and not strong; if it is too much, it will flow to other surfaces, which will leave stains, affect the appearance, and foam the data. Deformation will also affect the quality. If you want to increase the area of the joint, you can sprinkle some plexiglass powder (the powder collected when you file the plexiglass) around it and then drop it into chloroform. In addition, chloroform is toxic Chemicals, if you have a wound on your hands, you can't handle it, so as not to penetrate the body from the wound.
