What do woodworking mills have?

Everyone in the woodworking industry knows very well that the polishing of wood is very torturous. Today, I will introduce several commonly used polishing power tools to you. I hope these things can completely get rid of the pain of polishing.

1, electric mill

Commonly known as grinding head, electric grinder and electric grinder, it is an electric tool that uses grinding wheel or grinding disc to polish. The real charm of die electric grinding is that it can cut, trim, reshape, grind and polish metal and nonmetal materials with multi-purpose abrasive tools. Its main abrasives are:

(1) Cutting categories: resin high-speed cutting sand, net-laying cutting sand and emery cutting sand.

(2) Grinding: various special-shaped ceramic grinding heads, sand rings, sand cylinders, and page wheels with handles.

(3) Polishing category: wool felt wheel, felt sheet, cloth wheel, wire brush and copper wire brush (polishing paste for various purposes).

2. grinder

It is mainly used for grinding narrow, complex and inaccessible grinding parts, and is widely used for grinding die-casting products such as bicycles, aluminum alloys and zinc alloys. Advantages: large cutting capacity, high speed, convenient operation, small and difficult-to-grind surface, perfect solution, and easy operation for grinding with small angle and dead angle.

Matters needing attention in work

Check the work pressure, wear a mask at work and maintain it regularly.

Tool maintenance and maintenance

1, pneumatic tools focus on maintenance.

2. The air source of the tool must be treated to ensure cleanliness and dryness.

3. Please use the oiler to lubricate the tool and adjust the flow rate to 2 drops per minute. If the oiler is not used, 3-4 drops of lubricating oil must be injected from the pipe joint every day. Do not use high viscosity oil, which will make the tool rotate abnormally.

4. Don't throw or knock tools.

3, special-shaped grinding

Sander with special-shaped replaceable bottom plate. The use probability is not high. Suitable for some corners and difficult places. Special-shaped grinder is a common grinding tool. Because of its fine technology, the polished products are delicate and smooth, so today I will tell you about its polishing skills!

1, when grinding, grind along the grain, never grind vertically and horizontally, otherwise the grain will tear and the painted furniture will leave permanent defects.

2. When grinding with a special-shaped grinder, it is necessary to reasonably choose sandpaper with different thicknesses: a. It should not be too thick, and it is not appropriate to use one model too much; B. Don't jump sand (referring to the model of sandpaper), jump from 200# to 600# or 800#.

3. When grinding, generally use four fingers to grasp and thumb to hold sandpaper. When polishing furniture in a large area, you can pad square battens and polish them along the wood grain.

4, sand drum machine

Sand drum machine, the main shaft drives the sandpaper ring to move up and down, and the sandpaper ring rotates at a high speed, with the maximum sanding height of 98 mm The machine adopts a 450W high-power magnetic steel motor with a rotating speed of 2000 rpm. High grinding efficiency, smooth grinding surface, and create your perfect surface. Machines can be used to polish wood, metal, etc. The machine is equipped with cast iron table top, and the weight of the whole machine reaches 16 kg, which is heavy and stable.

5, sand table machine

Sandtable machine-sharp tool for corner grinding. A sand table machine belongs to woodworking machinery. It consists of a bracket, an abrasive belt working part, a grinding disc working part, an abrasive belt adjusting mechanism and a vacuum cleaner interface, and an anchor bolt is installed on the supporting leg of the bracket. The belt adjusting mechanism consists of a handle, a bracket, an eccentric sleeve, a turntable, an adjusting shaft, a turntable mandrel and a fine-tuning handwheel. The center of the bracket is sleeved on the eccentric sleeve, one end of the bracket is provided with a turntable shaft, and the other end is connected with a handle; The turntable shaft is installed in the long hole of the turntable; One end of the adjusting shaft is connected with the abrasive belt driven roller, and the other end is connected with the turntable; The inching handwheel is installed on the abrasive belt workbench. Turn the handle to change the abrasive belt quickly.

6. Belt sander

The belt sander comprises an abrasive belt, an abrasive belt shell for accommodating the abrasive belt, a motor, a motor shell for accommodating the motor, a handle, a driving wheel, a driven wheel and a transmission device for connecting the motor and the driving wheel, wherein the motor shell and the handle are integrally connected to form a unit, and the connecting device connects the unit to the abrasive belt shell. The unit body can rotate around its belt shaft, which is convenient for the belt sander to be in a comfortable operating position and can reduce the fatigue of operators working for a long time.

7. Circular saw lumber mill

Woodworking must be a good tool. It is not easy to buy in China at present. Its polishing effect is better. The disadvantage of 1 is that sandpaper is expensive, and the disadvantage of 2 is that it can't polish corners.

Characteristics of circular mill:

1) high grinding speed, effectively shortening the operation time.

2) Light weight, high balance and no fatigue after long-term use.

3) The dust suction type can effectively achieve the dust suction effect without dust flying.

The purpose of the circular mill:

1) automotive sheet metal painting operation.

2) Metal plate repair grinding, trimming and burr grinding.

3) Woodworking furniture, rims and metal polishing.

8. Square mill

There are a large number of substitutes in China, which have no patent influence. Ordinary sandpaper can be used and it is easy to buy. However, the quality is poor. I suggest buying Bosch or vauxhall.

Matters needing attention in operation:

Check the working air pressure; Please wear a mask at work; Regular maintenance.

Tool maintenance and maintenance:

1, pneumatic tools focus on maintenance.

2. The air source of the tool must be treated to ensure cleanliness and dryness.

3. Please use the oiler to lubricate the tool and adjust the flow rate to 2 drops per minute. If the oiler is not used, 3-4 drops of lubricating oil must be injected from the pipe joint every day. Do not use high viscosity oil, which will make the tool rotate abnormally.

4. Don't throw or knock tools.
