The electric angle grinder is a power tool for grinding. Because the axis of the grinding wheel is at right angles to the axis of the motor, it is especially suitable for applications where the position is limited and the ordinary sander is not used (such as corners, floor edges, component corners, etc.).
The electric angle grinder is an abrasive tool used for FRP cutting and grinding. The machine can be equipped with a variety of work heads, such as coarse grinding wheel, fine grinding wheel, polishing wheel, rubber wheel, cutting wheel, wire wheel and so on. The electric angle grinder is a grinding, cutting, descaling and polishing process of a metal member by using a high-speed rotating thin-plate grinding wheel, a rubber grinding wheel, a wire wheel, and the like. In 1906, Germany FEIN invented the world's first hand-held angle grinder; in 1987, Germany FEIN invented the world's first safe angle grinder for quick clamping system and brake system.
composition
1 motor, 2 large pulleys, 3 small pulleys, 4 belts, 5 bearing boxes, 6 quick joints, 7 soft shafts, 8 grinding head boxes, 9 grinding wheel pieces, 10 grinding head handles. The motor drives a bearing housing through the belt. After the speed is increased by the bearing housing, the driving shaft rotates rapidly, and then the soft shaft drives the grinding wheel (rotation) to work. The utility model has high working efficiency, long service life, low production cost and easy implementation.
Classification and model
Electric angle grinders are classified as compact angle grinders and large angle grinders, compact angle grinders: ultra-light, with or without safety configuration - meeting the requirements of diagonal grinders; large angle grinders: powerful, Suitable for difficult grinding and cutting operations.
According to the diameter and range of the grinding disc, the compact angle grinder models are divided into: WSB10-115T, WSG10-115, WSG10-125S, WSB14-125T, WSG14-125, WSG14-125S, WSG14-70E, WSS14-125 , MSFV649-1, WSG14-150.
According to the diameter of the grinding disc and the scope of application, the compact angle grinder models are divided into: WSG20-180, WSG25-180, WSB20-180, WSB25-180x, WSG20-230, WSB20-230, WSG25-230, WSB25-30x .
use
1. Different metal grinding and cutting and rust removal can be carried out by replacing different grinding wheel pieces;
Second, replace the stone cutting blade to process ceramic tiles, stone, and also cut wood small materials and thin wood boards (safer than cutting wood with a small saw blade mounted on an angle grinder);
Third, replace the hundred-page wheel, polishing wheel for metal polishing.
Operating specification
1. Be sure to check whether the angle grinder has a protective cover before use, whether the protective cover is stable, and the grinding plate of the angle grinder is installed securely.
2. It is strictly forbidden to use the worn-out grinding wheel. When cutting, it should prevent Mars from splashing, prevent splashing others, and keep away from inflammable and explosive materials.
3. Wear protective goggles and wear suitable overalls. Do not wear loose overalls. Do not wear jewelry or long hair. Do not wear gloves and cuffs.
4. When the angle grinder is just opened, there will be a large swing, and it should be firmly held.
5. After opening the switch, wait until the grinding wheel rotates stably before working.
6. The cutting direction cannot be directed to the person.
7. Stop after working for half an hour for 15 minutes, and then use it after cooling. After long-term use, the machine should run at no-load speed for a short period of time to cool the motor.
8. When cutting or grinding with an angle grinder, hold the angle grinder handle evenly.
9. Do not hold small parts by hand to machine the angle grinder.
10. If there is abnormal sound, or excessive vibration or leakage, stop the inspection immediately; before repairing or replacing the accessories, you must cut off the power supply and wait for the saw blade to stop completely.
11. When using a cutting machine, such as when working in a wet place, it must be carried out on an insulating mat or dry wooden board. Safety measures must be taken when climbing or in hazardous areas such as explosion protection.
12. The carbon brush of the angle grinder is a consumable item, so be careful to replace it after using it for a period of time. Be careful to make good contact when replacing.
13. When power is cut off, rested or left the workplace, the power should be cut off immediately.
14. Conscientiously clean the work environment after the work is completed.
