3 1.Particleboard Forming method: Particleboard is made of wood or other lignocellulosic material made of scrap, after the application of adhesive under the action of heat and pressure glued synthetic wood. Uses: mainly used in furniture manufacturing and construction industry and trains, carriages manufacturing. Features: The price is cheaper, and the horizontal bearing capacity, sound-absorbing and sound insulation performance is good; but due to particleboard particle structure gap (density), generally not easy to mill and do coated surface treatment. Surface treatment: The general surface can be affixed melamine finish, plastic edge available edge banding. Particleboard conventional thickness range (in mm): Particleboard is more affordable type of plate, plate thickness and the price is proportional to. Note: If there is customer need thickness of non-normal thickness, we can press two conventional thickness of board adhesive to customers the desired thickness size, for example: customers need a thickness of 28mm board, We can glue with a 21mm board and a 7mm board to get a 28mm board. 2. MDF Formation: High-density board is made of wood fiber or other plant fiber as raw material, applied urea-formaldehyde resin or other suitable adhesive made of artificial board. Uses: MDF and particleboard use is similar, but also for the furniture and construction industry and train, car car manufacturing. Features: MDF surface is smooth, not easily deformed due to external reasons, more suitable for all types of surface treatment (such as paste melamine skin, coating surface treatment, etc.); However, MDF easily deformed with water, and holding the nail poor, If the side of the thin MDF wood received teeth, MDF can easily be opened by the screw. MDF due to high density, will be heavier than the particleboard and other panels. Surface treatment: surface available paste melamine finish, can also be painted surface treatment, plastic edge can be used on the side or coated surface treatment. MDF conventional thickness range (in mm): Note: If you meet the needs of the board thickness is not normal, but also to use two or more conventional plate pressed into customers need the thickness.

4 3. Plywood Formed by: three or more layers of one millimeter thick veneer or sheet glued hot pressing, usually with an odd number of veneer, so there are three, five, seven and other odd-layer plywood. Uses: used in furniture and construction industry and trains, carriages and so on. Features: The texture of the plywood surface is very natural, not easily deformed and easy to process, but the price of plywood expensive than the particleboard and MDF. Surface Treatment: Generally take more coated surface treatment can also be polished. 4. Solid wood panels Formation: natural growth of trees, solid wood panels of various types, most of the solid wood prices are very expensive, such as rosewood, pear and so on. Uses: Solid wood are generally used for decoration, furniture manufacturing. Features: As solid wood is a natural growth of wood, so the structure of durable, natural lines, some wood can be said that the best wood decoration, but because of the high cost, very few people in the decoration on the extensive use of solid wood, except Tyrant. Surface treatment: As most of the solid wood has a beautiful natural wood, so many people are generally painted with a transparent way to deal with the surface, you can retain goodlooking wood but also moisture-proof. Common surface treatment details: Melamine finishes: The texture or color of the decorative paper into the melamine liquid inside the bubble, and then through the hot, the bubble over the melamine decorative paper pressed onto the plate. Melamine finishes a wide range of applications, less demanding on the board density, you can use particleboard, MDF and other man-made board surface, melamine finish can scratch, moisture, fire. Painted paint: Painted paint treatment is generally used in the relatively high density of the board, the general is the higher the density, the better the effect of paint. Such as MDF and plywood, solid wood panels and other sheet surface can be painted paint processing, but different methods of painting the board will be different, such as solid wood panels, solid wood panels to paint, you must first use coarse sandpaper to the surface of solid wood Polished more smoothly, and then the initial painting, the first painted paint to dry again after the repeated steps to use again, but the second grinding to use fine sandpaper. Edge: There are two kinds of machine edge sealing and manual edge sealing, machine edge refers to the use of automatic edge banding machine to carry out edge sealing, the machine edge sealing generally only straight edge; when faced with arc or other shapes need edge sealing When we usually will be artificial Edge. Artificial edge details: the plastic edge of the wood and wood contact surface adhesive, and then paste, and then hit the plastic jumper can be, regardless of the machine Edge or artificial Edge, Edge Edge generally have to edge deal with. I know there are a lot of wood used in the market. At present, only the wood and surface treatment are learned in the process of learning. I hope to have access to and learn more about the wood and its processing technology in the future.

5 1. Automatic feeding machine: According to the request automatically cut the board into several equal shares. Automatic feeder can cut different sizes of sheet, you can accurately grasp the opening size, tolerance can even be controlled to 0.2mm or less. Automatic feeder for different materials used by the knife is not the same, the general can cut wood and acrylic, PVC and other materials, it is practical. 2.polishing machine: When the wood surface is not smooth, polished by polishing machine, in order to achieve the desired smoothing effect. For example, the feeder opened a long piece of material, but the incision a lot of flash, can not meet customer requirements, then we can use the polishing machine to the side of the plate polished in order to achieve smoothing effect. 3. Angle cutting machine: When the edge of the wood needs splicing, the machine cuts the edges of the wood at different angles. For example, at the corner of some cabinets, it is necessary to cut the two connected plates into a 45 degree splicing effect and use the angle cutting machine to cut the edge. 4. Automatic feeder: Feeding can be done automatically. (Because at that time did not see Master Liu started the machine, so the use of this machine to understand the use of less)

6 5.CNC machine: Plank can be a plane drilling, carving patterns, straight lines and curved cutting, more comprehensive functions, but also to other materials such as plastic sheet metal processing. CNC CNC machine can be very precise control of product size, usually can be controlled to 0.2mm or less. CNC machining is done by rotating a circular knife at a high speed. When an internal gong is empty for some of the plates, an R corner is usually found where there is an inner corner. The size of the R corner depends on the diameter of the knife used by the CNC at the time. 6. Automatic drilling machine: Generally used for perforating the side of the plate. Place the board on the machine countertop, clamp it, and punch the sides of the board from the machine head. Bit position 7. Platen machine: Can be two or more different thickness of the board to form a plate of non-conventional adhesive pressure plate thickness of nonconventional, very practical equipment. For example, we said earlier encountered an unconventional thickness of the plate, you can use the plate press to complete the different thickness of sheet metal synthesis. 8 double-headed processing machine: Can both sides of the board at the same time cutting and other processing machines. 9. Automatic edge banding machine: You can quickly edge straight wood board edge, fast, the disadvantage is that the curvilinear edge Edge. So some curved desktop still need manual edge banding.

7 Rounded cutting machine The fillet cutter's knife is also a cylindrical drill similar to a CNC, cut at high speed. The fillet cutting machine has a section of the head is smooth, used to avoid (not cutting) mold plate. Generally use the fillet cutting machine to round the plate prior to cutting, must first nailed a plate used to fix the plate and mold the border, and then to be processed at the right angle plate and mold plate part of the corner overlap, and Edge alignment, push the right angle to the cutter back and forth rotating cutting, to ensure that all parts cut in place. The bottom is the mold plate, the size of the fillet R made depends on the size of the mold plate fillet R.

8 Example: We want to do the effect of the plate, 25% thick 2. Take one of the plates, CNC CNC machine with a good material Internal gongs, the same with CNC Machine again into the external shape of the plate Line processing obtained around the shape of rounded corners, U-shaped gap in the middle at the same time using CNC gongs Shape, the last punch directly It's finished Note: Internal machining of CNC machining The corner is generally R angle, R angle The size depends on the CNC machining time The diameter of the knife used. 1. Take a piece size of 2440 * 1220mm The whole board, with the feeder out 4 size is 1020 * 610mm (leaving margin) Around the board, and no R around the corner, Thickness of 25mm
