What issues should you pay attention towhen using
green cutting disc? Here are some points for everyone:
Protection problem--The protective cover isthe main protection device of the grinder. Its function is: When the cutting
piece is damaged due to work, it can effectively cover the grinding wheel
fragments and ensure the safety of personnel. The shape of the wheel guard is
round and square, and the opening angle is not allowed to exceed 90°; the
material of the shield is steel with a tensile strength of not less than 415
N/mm2. When replacing a new grinding wheel, the protective cover should be
installed firmly and reliably, and the protective cover should not be
dismantled or discarded.
Blocking the screen is one of the mainprotective attachments of the grinder. The opening of the guard above the
horizontal plane of the main shaft is greater than or equal to 30 (this device
must be provided. Its main function is to block the flying during the grinding
process, so as not to hurt The operator is installed at the positive end of the
protective cover opening, the width should be larger than the width of the
wheel guard, and should be firmly fixed to the protective cover. In addition,
the clearance between the circumferential surface of the grinding wheel and the
baffle should be less than 6mm.
Bracket problems - brackets are oneof the commonly used attachments for grinders. Adjustable brackets must be
provided for grinders with a specified grinding wheel diameter of 150 mm or
more. The distance between the grinding wheel and the bracket should be less
than 1/2 of the size of the workpiece to be ground *, but * should not exceed 3
mm.
Grounding problems - The grinder usespower lines, so the enclosure of the equipment must have good grounding
protection. This is also one of the important factors that cause accidents.
