1, the use of units received abrasive, should be carefully examined for cracks and other damage, and carefully check the abrasive surface of the trademark symbol is correct, clear and complete.
2, abrasive in handling should be handled with care to prevent vibration and impact, and to ban rolling on the floor.
3, abrasive storage should prevent moisture, cold, room temperature should not fall below 5 ℃.
4, resin abrasive contact with alkali substances can not avoid reducing hardness and strength, storage periods exceeding one year, shall be re-rotation strength test, before use.
Correct installation of wheel
1, the installation should be carefully examined before grinding wheel for cracks and percussion hammer with a wooden wheel, listening to whether there is voiceless, if found to have cracks and voiceless, install and use is strictly prohibited.
2, proofreading and the wheel spindle speed is the maximum safe use of face indicated speed match.
3, when the wheel is installed, you should use the chuck fastening, two chuck diameter size must be equal. Two end faces of the chuck and the grinding wheel should be placed on an elastic material having a thickness of 1-1.5 mm asbestos pad, rubber board or cardboard.
4, an outer diameter of 150 mm and above grinding wheel, mounted on card late static balance should be done first; then install the grinder to be trimmed, trimmed should be balanced again before use.
5, wheel diameter and spindle (or sleeve) of the elastic to fit properly, the gap is not easy to be too large.
6, fastening wheel, only allows the use of dedicated manual nut wrench, prohibited the use of clamps or banging supplementary tool, if multiple compression screw, they should be diagonal sequence tighten tightening force should be uniform. Fastening, attention should nut or screw tightness, tighten wheel drive does not produce enough to slide the extent appropriate, caused by excessive clamping force to prevent wheel breakage.
Safety wheel
1, in the starting machine, you should check the machine guards and a variety of actions to adjust the reset switch is in place and secure.
2, using a protective cover, covering at least half the diameter of wheel.
3, wheel mounted on the grinding spindle, you must be idle, idle time less than 5 minutes.
4, not specifically to work with the end face grinding wheel, prohibit the use of grinding wheel face.
5, during the grinding process to prohibit the use of leverage to push the workpiece increases the pressure on the wheel.
6, or grinding wheel dressing, the cutting depth should be appropriate, and the use of specialized dressing tool wheel dressing.
7, the wheel stops rotating before the coolant off, so as not to affect the wheel balancing.
8, prohibit the use of binders for abrasive grinding fluid destructive.
