Grinder cutting use precautions

Grinder cutting use precautions

Side grinding problem in everyday use bench grinder wheels, we often can find some operator, regardless of the type of grinding machines, regardless of the type of wheel, grinding on the use freely the side of the wheel, which is a serious violation of the security operation rules of conduct illegal operations. By regulations do with the circumferential surface of the side face should not be used for grinding wheels, large radial strength of this wheel, axial strength is small, will cause the wheel broken, even wounding the operator the force is too large, the actual The use of the process should prohibit such behavior. Positive operational problems in everyday use, many operators facing the grinding wheel always used to operate, because this direction can pull its weight, in fact, this behavior is the behavior of operating wheel should be particularly prohibited. Follow the rules, the use of grinders grind the workpiece, the operator should stand on the side of the wheel, can not operate on the front wheel, when the wheel in order to avoid failure, or the wheel broken wheel fly flying wounding. Operational problems in the use of force grinder, some operators, especially the younger operators, for the sake of grinding speed, force too much too fast, this is a very unsafe behaviors. Any wheel body has a certain level of strength, doing so will likely result in broken wheel, and even flying wounding, but also a behavior should be prohibited. Common operational problems in the actual daily operations, there are also so happens, was in a hurry production tasks, grab working hours, the two men share a grinder while operating, which is a serious violation of operating behavior should be strictly prohibited. A grinder is not enough time, it can be used to add grinder solutions, and definitely not at the same time share a grinder.

Grinder cutting installation Notes

bench grinder wheels installation Notes
First of all to the quality and safety wheel while installing detection method, with Nepalese cashmere hammer (you can also use a pen) tapping wheel side, the sound crisp, no problem. Location problem grinders installed in any position, the installation process is that we first of all Issues to consider only selected reasonable and appropriate position, we can carry out other tasks. Grinders prevent the installation of the device in the vicinity of and facing the operator or where in the past was often generally larger wheel workshop should set up a dedicated computer room. If indeed due to terrain limitations plant can not set up a dedicated wheel room, shall be installed in the front of the wheel height of not less than 1.8m protective bumpers and tailgate require a solid and effective. Unbalanced wheel balance problem mainly by wheel manufacture and installation of inaccurate center of gravity so that the wheel does not coincide with the rotary shaft caused. Harm imbalance mainly manifested in two aspects, one at the wheel rotating at high speed, causing the vibration, could easily lead to the workpiece surface polygon oscillation marks; on the other hand, unbalanced spindle vibration and accelerated bearing wear, serious When will cause wheel breakage, and even cause accidents. Therefore, it requires a lot greater than or equal loaded directly on the card should be static balance after-hours, when after a plastic wheel trim or find an imbalance in the work, should be repeated static balance 200mm of sand building. Matching matching mainly refers to the chuck and thecutting wheels mounting support issues. According to standards, wheel chuck diameter not less than the diameter of the building is mounted sand 1/3, and the corresponding provisions of wheel wear to chuck diameter larger than the diameter of 10mm should be replaced with a new wheel. Thus there is a matching chuck and wheel, otherwise it will happen, "big horse car" wasteful equipment and materials; "small horse cart" do not meet the safety requirements, could easily lead to accidents. Therefore, a reasonable match chuck and wheel, on the one hand can save equipment, cut about material; the other hand, compliance with the requirements for safe operation. Further, between the grinding wheel and chuck chuck should install a diameter greater than the diameter of 2mm, 1mm ~ 2mm thick cushion. Protective shield problem is the most important grinding machine guards, whose role is: When the wheel for some reason destroyed at work, covering the grinding wheel fragments effectively ensure the safety of personnel. The shape of the wheel shield round and square, the maximum opening angle must not exceed 90 °; shield material is not less than the tensile strength of 415N / mm2 of steel. When replacing the new wheel, shield installed to solid and reliable, and the shield must not disassemble or discarded without. Quiet block panel is one of the main protective accessory grinders, protective cover over the opening in the spindle level greater than or equal to 30 must be set for this device (when. Its main function is to block the grinding process flying quiet, so as not to hurt operator. It is attached to the positive terminal of the protective hood opening, the width should be greater than the width of the wheel guard, and should be firmly secured protective cast. In addition, the peripheral surface of the grinding wheel requires clearance baffles should be less than 6mm. carriage problem bracket It is one of the common attachment grinder, according to the provisions wheel diameter of 150mm or more grinders adjustable bracket must set distance between the wheel and bracket should be less than the workpiece to be ground to make the smallest form factor of 1/2 inch, but the maximum One of the important factors should not exceed 3mm. Grounding grinder using power lines, and therefore the equipment housing must have a good grounding protection. It is also easy to cause

Selection cutting wheel

Selection cutting wheel
1, cutting wheels no crack no damage.
