What are the woodworking grinding tools, and what tools are used for wood grinding and polishing?

Woodworking Grinding Tools:

1. Electric grinding. Commonly known as grinding head machine, electric grinder, electric grinder, is a kind of power tool that uses a grinding wheel or grinding disc for sanding. The real charm of electric die grinding lies in the fact that it can be used with multi-purpose abrasives to cut, dress, shape, grind and polish metallic and non-metallic materials.

2. Sand strip machine.

It is mainly used for grinding parts that are narrow, complex and difficult to enter the grinding, and is widely used in the grinding of bicycles, aluminum alloys and zinc alloy die-casting products. It has a large cutting capacity, fast speed, easy to operate, narrow and difficult to grind surface, which can be perfectly solved, easy to operate, suitable for grinding at small angles and dead corners.

3. Special-shaped grinding.

A sander with a special-shaped replaceable base plate. The probability of using it is not high. Suitable for some corners and places that are not easy to handle. The special-shaped grinder is a common grinding tool, because of its fine process technology, the polished product is delicate and smooth. Woodworking grinding skills:

1. Reasonable selection of sandpaper with different thicknesses: should not be too coarse, should not use too much of a model, should not jump sand.

2. When polishing, polish along the wood grain, never grind vertically and horizontally, otherwise the wood grain will crack, and the painted furniture will leave permanent flaws.

3. The corners and edges of the polished object should not collapse, and the action should be light, and the original round or square outline must be maintained. The decorative line must be kept straight and not bent, broken or deformed.

4. When grinding, generally press with four fingers and palms, and hold the sandpaper with your thumb. When polishing furniture with a large area, you can cushion square wood strips and polish along the wood grain.

5. Brush while grinding, you must use a dry brush to brush off the dust and ash at any time when grinding, and brush while grinding until the surface is flat and smooth.

The tools that are generally needed are: cleaning tools, washing machines, water tanks, water suction machines, high-speed polishing machines, air dryers, wax mops or tiger clips, towels, water presses, rags, etc.

The speed of the turntable can be appropriately increased during fine polishing, and the polishing time is appropriate to throw away the damaged layer of rough polishing. The polished surface is as bright as a mirror, and scratches are not visible in the microscope's bright field of view, but they are still visible in phase contrast lighting.

Classification of polishing discs

According to the connection between the polishing disc and the polishing machine, it can be divided into the following three types: bolt disc: suitable for polishing machine with bolt joints. Nut disc: suitable for polishing machines with nut joints.

Suitable for polishing machines with suction cups. That is, the head of the polishing machine is fixed with a hard plastic polyester chassis (also known as a tray) with screws, and the working surface of the chassis can stick to the object with a nylon easy-to-stick plane, so that you can choose a variety of suction cup type polishing discs according to your needs, and you only need to stick this kind of polishing disc on the chassis, which is extremely convenient to use.

Grinding methods include dry grinding, water grinding, oil grinding, wax grinding, and toothpaste polishing. Dry grinding is divided into coarse grinding, flat grinding and fine grinding, of which coarse grinding is generally used to remove wood wool, scars, glue marks and pencil marks and other dirt in the pre-treatment, while flat grinding is usually wrapped in a small wooden block or hard eraser of the abrasive cloth, sandpaper to polish the large plane, so that the leveling effect is better, fine grinding is generally used in scraping putty, sealing paint, color matching and complementary color after the middle layer of each middle treatment, sanding requires careful care. Water grinding is sanding with water dipped in water (or soapy water).

Water grinding can reduce wear marks, improve the smoothness of the coating, and save labor and sandpaper.

Sandpaper commonly used in construction includes wood sandpaper, water sandpaper, iron sandpaper, etc. Generally, the putty sanding with partial filling should be made of No. 1 or 1 wood sandpaper; The full scraped putty and primer layer should be sandpaper No. 0, and the middle layers of paint film should be finely sandpapered No. 00. Some paint films are dry ground with sandpaper, and friction and heat will cause the paint film to soften and damage the coating film, so water sandpaper should be used for wet grinding.

Before wet grinding, put the water sandpaper in water to soak, then wrap it outside the neatly folded cloth, and then dip it in soapy water to sanding on the paint film, so that the water sandpaper is wrapped outside the cloth, which can expand the area of sanding and use force. In order to improve work efficiency, electric grinders can also be used in large-area grinding construction, generally there are disc type, vibrating type, belt type and drum type.

The following points should be paid attention to when sanding:

1. Blanks that have not been coated with any paint, plain wood, furniture, musical instruments, handicrafts, etc., should be wiped with a damp cloth before polishing construction, and after the moisture is dry, use No. 1 sandpaper to sand along the wood grain (note that it must follow the wood grain);

2. Where the wood is not flat enough, you can use sandpaper wrapped in small wooden blocks or hard rubber to polish, and do not grind vertically and horizontally when grinding, otherwise the wood grain will be broken, and the painted furniture will leave permanent flaws;

3. When polishing the edges and corners, pay attention to light grinding, the edges and corners can not collapse, and be sure to maintain the original round or square outline. The decorative line must be kept straight, not bent, broken, or deformed;

4. Grinding should be brushed while grinding, because the wood sandpaper sand particles are easy to fall off, there is a possibility of grinding the wood grain after rubbing the surface of the object. In addition, the dust from sanding is easy to embed in the bristles, so it is necessary to brush off the dust with a dry brush at any time during sanding, brushing while grinding until the surface is flat and smooth;

5. When grinding the surface of the thicker putty, it is necessary to adhere to the principle of "based on the high and smoothing with the plate", and must not be blindly sanded; The closer to the surface of the paint layer, the higher the quality requirements, the finer the sandpaper used for sanding should be, and sometimes the old water sandpaper can be used for sanding, which is economical and does not hurt the paint film.

Money-saving sanding techniques - carpentry.

<> "1. What tools do you need for wood polishing?

Sandpaper can be used, but there are many types of sandpaper, such as wood sandpaper, water sandpaper, iron sandpaper, and so on. Part of the polishing can be equipped with No. 1 wood sandpaper, putty and primer can be equipped with No. 0 sandpaper, the delicate paint film in the middle needs to be prepared with No. 00 sandpaper, some paint film rubbing with sandpaper will cause local heating and softening damage, so in this case, water sandpaper needs to be configured.

Second, what are the points to pay attention to in carpentry construction?

1. Before construction, the corresponding materials must be prepared, and they must be purchased in regular shopping malls, so as to ensure that the products purchased are qualified, reduce decoration pollution, and the actual construction must control the wild track and budget, but the standard of materials cannot be discounted, and it is forbidden to cut corners.

2. Carpentry construction must do a good job of corresponding moisture-proof and anti-corrosion measures, such as the wardrobe near the washing machine wall and the hollow-making type wall, must be painted with two o'clock and moisture-proof paint to continue the construction, and the original wall wood decorations must be paved with moisture-proof paper.

3. The configured wood must be dry, if the wood is not dry and used in the project, it will crack and deform due to the reduction of its water volume. Therefore, it is necessary to give preference to materials that are less affected by moisture, such as cabinets can be equipped with ecological boards, and floors can be equipped with composite flooring, the properties of these materials are stable and will not be easily disturbed by weather changes.

4. In addition, in order to ensure that the quality of the project is up to standard, the closing of solid wood door covers, window covers, closing edges, and decorative boards must be tight, firm and smooth.

<> tools: hand-held electric drills, grinders, wire sawing machines, sanding disc machines, etc. A hand-held electric drill is mainly a machine used to carry out perforation and punching by hand.

The grinding machine, there are two kinds of round and square, the machine is highly efficient, easy to operate and fast, and is very suitable for grinding work in large areas. Wire sawing machine, a kind of curved woodworking table used to make a large degree of shape change, is one of the indispensable operating tables for manual work. The sand disc machine is used to carry out punching operations on the wood, and is suitable for holding the wood by hand for further operation, and is a tool with high safety performance.
