grinding power tools

People in the wood industry are very clear that the grinding of wood is very afflicting people. Today we introduce nine kinds of commonly used grinding power tools. I hope that these things will allow you to completely liberate and polish.


1, electric grinder

Commonly known as grinding machine, electric grinder and electric grinder, it is a kind of electric tool that uses sand wheel or disc for sanding. The true charm of the die grinder is that it can be used for cutting, trimming, sculpting, grinding and polishing of metal and non-metal materials in combination with various abrasives. Its main abrasive abrasives are:

(1) Cutting class: high-speed resin sanding, cutting sand with cloth, diamond cutting

(2) Abrasives: Various special-shaped ceramic grinding heads, sand rings, sand drums, and handles

(3) Polishing class: wool felt wheel, felt sheet, small cloth wheel, wire brush, copper wire brush (with various uses of polishing paste)


2, sand machine

The grinding power tools are mainly used for grinding small, complicated and hard to enter the grinding area. It is widely used in the grinding of bicycles, aluminum alloys and zinc alloy die castings. Advantages: Larger cutting capacity, fast speed, easy operation, narrow and difficult to grind the surface, can be perfectly solved, the operation is easy to be suitable for small angles, grinding at dead ends.


Work Precautions

Check the working air pressure, wear masks, regular maintenance and maintenance when working.

Tool maintenance and maintenance

1, pneumatic tools focus on maintenance and maintenance.

2. The gas source of the supply tool must be treated to ensure it is clean and dry.

3. Use a lubricator to lubricate the tool and adjust the flow rate to 2 drops per minute. If you do not use a lubricator, you must inject 3-4 drops of lube each day from the fitting. Do not use high-viscosity oils that will cause the tool to turn abnormally.

4. Do not throw or hit the tool.


3, shaped grinding

Shaped sander with replaceable floor. The probability of use is not high. Suitable for some corners and difficult to handle places. Profile grinding machine is a common grinding tool. Because of its fine process technology, the polished product is exquisite and sleek, so today we tell you about its grinding skills!

1, polished along the wood grain, never rub randomly, otherwise it will tear the wood, painted furniture will leave a permanent flaw.

2, when the profiled sander is polished, it is necessary to use a different thickness of sandpaper: a. It should not be too thick, it should not be too much with a model; b. Should not jump sand (refers to the sandpaper model), jump from 200# To 600# or 800#.

3, when grinding, generally use four fingers and palm press, thumb grip sandpaper. When grinding a furniture with a large area, the mat can be polished along with the wood grain.


4、Drum machine

Sand drum machine, the main shaft to drive the sandpaper ring to move up and down, coupled with high-speed rotation of the sandpaper circle, the maximum sanding height of 98mm. The machine uses 450W high-power magnet steel motor, the speed reaches 2000 revolutions per minute, sanding efficiency is high, speed is high, the sanding surface is very smooth, creating your perfect surface. The machine can be used to sand wood, metal, etc. The machine is equipped with a cast iron countertop. The machine weighs 16 kg and is heavy and stable.


5, sand disc machine

Sand disc machine - angle grinding tool. Sand disc machine is a woodworking machine. The utility model is composed of a bracket, an abrasive belt working part, a sand disc working part, an abrasive belt adjusting mechanism and a vacuum cleaner interface, and anchor bolts are arranged on the bracket legs. The belt adjustment mechanism consists of a handle, a bracket, an eccentric sleeve, a turn plate, an adjustment shaft, a turntable spindle, and a fine adjustment hand wheel. The middle of the bracket is set on the eccentric sleeve, one end is equipped with a rotating plate spindle, and the other end is connected with the handle. The rotating plate spindle is installed in the long hole of the rotating plate, one end of the adjusting shaft is connected with the passive roller of the abrasive belt, and the other end Connected to the turntable, the micro-motion handwheel is mounted on a belt worktable. Swivel handle can quickly replace the belt.

6, belt machine

Sanding belt machine, including abrasive belt, abrasive belt housing containing abrasive belt, motor, motor housing accommodating motor, handle, driving wheel, driven wheel and transmission device connecting said motor and driving wheel, motor housing A unit body is integrally formed with the handle, and a connecting device connects the unit body to the belt housing. The above-mentioned unit body can be rotated about the axis of its belt, which facilitates the belt machine to be located in a comfortable operating position, which can reduce the operator's long-term fatigue.


7, round grinding machine

Woodworking essentials. It is not easy to buy at present in China. It has a better sanding effect. The disadvantage is that the sandpaper is expensive, and the disadvantage 2 is that it cannot polish the corner.

Circular mill features:

1) The grinding speed is fast and the working time is shortened effectively.

2) Light weight, high balance, and no fatigue for a long time.

3) The vacuum cleaner can efficiently achieve the vacuum effect without scattering of dust.

The use of round mill:

1) Automotive sheet metal coating operations.

2) Grinding, trimming and feathering of sheet metal.

3) Woodworking furniture, rims, and metal grinding.


8, grinding machine

Precautions during operation:

Check the working air pressure; work masks, regular maintenance and maintenance.

Tool maintenance and maintenance:

1, pneumatic tools focus on maintenance and maintenance.

2. The gas source of the supply tool must be treated to ensure it is clean and dry.

3. Use a lubricator to lubricate the tool and adjust the flow rate to 2 drops per minute. If you do not use a lubricator, you must inject 3-4 drops of lube each day from the fitting. Do not use high-viscosity oils that will cause the tool to turn abnormally.
