After the selection of the advertising engraving machine tool is always broken?

If you eat the knife too deeply, it will break. If you go too fast, it will break. If the knife is too fast, it will break. If the knife is too long, it will be shaken. If the tool is used incorrectly, the knife will be broken, and all kinds of breaks will depend on the hardness of the material. Urgent. Novices prefer to use a single-edged milling cutter. This knife is not enough to make a dense material (such as bakelite, fiberglass, or composite). According to the material selection tool, the double-edged or corn knife can be used for the high density. According to the minimum size of the drawing, you can also choose a larger knife, 4MM/6MM, not necessarily 3.175. For workpieces with a thickness of more than 20 mm, the tool must be long, and the principle of leverage will be broken or shaken when it is long. The depth of each knife is set to about 1 mm and then layered down. In addition to the above-mentioned several seconds, the fatigue of the metal is predictable: the sound is heard during the processing, and the sound of the normal cutting is relatively clear, relatively sharp, carefully discerned, and has a flawless cutting sound. It is very turbid with vibrating Weng Weng, and it is necessary to quickly slow down the feed rate, otherwise it will break the knife. If you can't hear it, touch the workpiece with your hand, and the vibration will be broken.

Advertising engraving machine tool selection engraving 20mm plexiglass?

1, can be carved with a 3.17 knife.

(1) Fix the material to be engraved on the engraving machine, and use screws and press buttons. Note: Try to make the horizontal and vertical directions perpendicular to the horizontal and vertical directions of the engraving machine.

(2) installing a milling cutter;

(3) Open the operating system of the engraving machine (here, the Weihong system is taken as an example);

(4) Load the engraving file (file type is NC) that needs to be engraved.

(5) Start and finish.

2, you can also use a single-edged cone knife (flat-bottomed sharp knife).

Ad engraving machine tool selection considerations?

Pay attention to the influence of the cutting edge angle and the blade width on the machining accuracy and progress. If the cutting edge angle and the blade width are large, the machining speed is fast, but the machining pattern is not fine, and the cutting edge angle and the blade width are small, the machining speed is slow. However, the graphics are fine and the durability of the tool is relatively poor.

The main purpose of advertising engraving machine?

1. Cross-section planing: The undulating organic plate section can be flattened with a plane, and the electric planer can be roughly ground by a grinder, and then placed on the belt machine to smooth. The thin plate is clamped together by a pressure iron clamp at the same time, and straightened by an electric planer or a belt machine. In this way, ergonomics can be improved, and the consistency of the multi-plate size is also ensured. Professional manufacturers generally have special iron clips, which clamp the large pieces of organic pieces and then flatten them with electric planers. For small-area boards, it is good to clamp the flat with a bench vise.

2, cutting and cutting: plexiglass board conventional size is 1830mm × 1220mm, 2160mm × 1220uum, etc., according to the drawings provided by the customer, draw a cutting line on the board, the size of the drawing should be larger than the actual size of 0.5 ~ 3mm. The plate of 5mm or more is directly cut by a saw. Under 5mm, the shallow groove can be hooked out by a hook knife, and then the plate is broken by a knife. When using a chainsaw, you should pay attention to safety, and the two steps in the same direction, and strive to maintain balance. It is very important to cut this process. It is related to whether the following processes can be carried out smoothly. Must be done: the marking is accurate, the cutting is reasonable, and the sawing line is straight.

3. Bending: It is often necessary to bend the plates into various angles by processing various display frames with organic plates. According to the length of the bending line, a plurality of heaters of different lengths can be made, and the heater is made of flat aluminum alloy profiles. Method: Firstly, a 3~5mm groove line is opened on the aluminum profile so that the heat of the heating pipe overflows from it, and the two sides of the groove line are attached with hard wood board, which can function as a heat-insulating non-stick plate. Then, the quartz heating tube is fixed in the aluminum tube with an iron clip, and the power cord can be connected. Where the organic plate is bent, a shallow line is drawn with a hook knife, so that the folded corner line can be both square and accurate. During the heating process, the heating line of the organic plate must be pressed by the square wood, so that the heating wire is heated and balanced, and the folded corner line will be straight, without the occurrence of pile meat or local cracking. For different bending angles, wooden molds with different angles are also required.

4, polishing and polishing: the role of polishing is to restore the radiant brightness of the damaged organic plate section. The already flattened sheet is further ground with water sandpaper and then polished with a polisher. During the polishing process, some polishing soap (green soap, white soap) should be rubbed on the cloth wheel from time to time to speed up the polishing. Various scratches are often found on transparent organic boards and are also polished prior to printing or bonding. The flame polishing machine has become an indispensable auxiliary equipment for carving crystal characters. Its official online shop has also received a lot of attention: http://shop61207369.taobao.com/ With the advent of engraving machines, the organic plate section also uses flames. The processor performs the bright processing, but the effect is not satisfactory. It is best to use a laser cutter for a plate with high quality requirements.

5, slotted drilling: signage panel or display rack often need to open the slot, slotted with vertical milling machine, 冉 equipped with a variety of tools; open hole need to buy a set of hole opener, hole opener The hole can be completed on the table drill, and the ordinary drill bit can be used for the hole below 13mm.

6. Adhesion: The more commonly used binder is chloroform solution. The solution is sucked into the needle tube by the injection needle tube, and the bonding effect is good in the welding gap. For the large-area bonding, the crystal glue can be used, the bonding position is high, and the car is still good, and the use is also used. Strong adhesives such as 502, 110, etc., are also very convenient to bond, but the price is slightly more expensive. In the advertising system, there are many enterprises that focus on screen printing and plexiglass carving and processing. They have also achieved good economic and social benefits.
