flat cutting disc Abrasive cutting - cutting grinder Precautions

Wheel of use of certain hazardous. For everyone's safety, use the list below Note: tile granite cutting disc‍ Grinder is one of the most commonly used machine shop equipment flat cutting disc, its installation is reasonable, whether compliance with safety requirements; its use is correct, whether compliance with safety rules . These issues are directly related to the safety of every employee, and therefore the actual use high quality disc‍ must arouse our attention.

LEMAN metal cutting discs Precautions during installation

First, the quality of the grinding wheel to be safe when installing detection method, Nepal velvet hammer (you can also use a pen) tapping the side wheel, crisp sound is no problem. abrasive cutting disc‍ Positioning grinding machines installed in any location, is our first installation process issues to consider only selected reasonable and appropriate location, we can carry out other tasks. Grinder prohibit installed facing or near the equipment and the operator has often been in the past where, generally larger wheel shop should set up a dedicated room. If indeed due to terrain limitations plant can not set up a dedicated wheel room, should be installed in the front wheel drive is not less than 1.8m high protective baffle and baffle requires strong and effective. Unbalanced balance wheel is dominated by manufacturing and installing wheel inaccurate, rotary grinding wheel does not coincide with the center of gravity caused. Harm imbalance mainly manifested in two aspects, one in the high-speed rotating grinding wheel, causing the vibration, could easily lead to the workpiece surface polygonal oscillation marks; hand, unbalanced spindle vibration and accelerated bearing wear, serious when will cause wheel breakage, or even cause an accident. Therefore, requiring great or greater installed directly on the card should be carried out late diamond grinding cup‍ static balance wheel in the plastic trim or discovered after an imbalance in the work, should be repeated static equilibrium 200mm sand office. Matching matching problem mainly refers to the chuck and the wheel mounting support issues. According to standards, wheel diameter not less than chuck is mounted sand office diameter of 1/3, and the corresponding provisions of wheel wear to a larger diameter than the diameter of 10mm chuck should be replaced with a new wheel. Thus there is a matching problem chuck and grinding wheel, otherwise it will be the case, "Mara 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 grinding wheel, one can save the device, cut about materials; hand and meet the requirements for safe operation. Further, between the wheel and the installation of a larger diameter than the chuck should chuck diameter 2mm, 1mm ~ 2mm thick cushion. Protection issues grinder shield is the most important protective device, its role is: When the wheel for some reason destruction at work, covering the wheel fragments can effectively ensure the safety of personnel. The shape of a circular wheel guard and square, which must not exceed the maximum opening angle of 90 °; shield material is not less than 415N/mm2 tensile strength of steel. When replacing the new wheel, protective cover installed to a solid and reliable, and the guard shall not disassemble or discarded. Quiet block panel is one of the main protective accessories grinders, protective cover over the opening in the horizontal axis is greater than or equal to 30 must be set for this device (when it's main function is to block the grinding process of flying quiet to avoid harming operator it being attached to the open end of the shield, a width greater than the width of the grinding wheel guard, and should be firmly secured in a protective cover. Moreover, the circumferential surface of the grinding wheel requires baffle gap should tile granite cutting disc‍ be less than 6mm. problem carriage bracket is one of the commonly used accessories grinders, according to the provisions wheel diameter of 150mm or more grinders must set the adjustable bracket. distance between the wheel and bracket should be smaller than the smallest form grinding every inch piece of 1/2, but the maximum should not exceed 3mm. grounding problem grinder using a power line, so the equipment enclosure must have a good grounding protection device, which is also one of the important factors that could easily lead to accidents.

stainless steel cutting discs Precautions during use

Side of the grinding wheel machine problems in daily use, we can often find some kind of grinding machines, regardless of the operator, regardless of the metal cutting wheels‍ type of wheel stainless steel cutting discs, optionally grinding wheel on the use of the side, which is a serious breach of security operations Statutes illegal operation behavior. Made according to the rules with the circumferential surface of the side face of the grinding wheel should not be used, higher radial strength of this wheel, the axial strength is small, the grinding wheel can cause crushing injuries or excessive force when the operator, the actual the use of the process should prohibit such behavior. Positive operational problems in everyday use, many operators are facing the wheel always used to operate, because this direction can be diamond disc‍ put into effect, in fact, this behavior is the behavior of grinder operation should be particularly prohibited. Follow the rules, the use of grinders grind the workpiece, the operator should stand on the side of the wheel, the front wheel may not operate when the wheel to avoid a failure, or the wheel broken wheel flying 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 behavior. Any wheel body has a certain level of intensity, this could cause the wheel broken, and even flying out of wounding, but also a should be prohibited. Common operational problems in the actual daily operations, there are also so happens, someone to catch production tasks, rob working time, the two share a grinding machine while operating, which is a serious violation of operating behavior, abrasive cutting disc‍ should be strictly prohibited. A grinding machine is not enough time, can be used to add grinders solution, and definitely not at the same time share a grinder.

flat cutting disc Precautions replacement process

Any wheel wear problems have some wear and tear of its requirements, wear a certain extent it is necessary to replace the new wheel. Not in order to save material, it requires the bench grinder wheels‍ use of ultra-wear, which is a very unsafe illegal behavior flat cutting disc. A general rule, when the wheel wear to a larger diameter than the diameter of 10mm chuck should be replaced with new wheel. Valid questions from the Treasury brought out a new wheel is not necessarily qualified wheel, new wheel even buy from the manufacturers are not necessarily qualified wheel. Any wheel has its certain expiration date, within the validity period of use, it is qualified wheel; than valid use, it is not necessarily qualified wheel. Rules of order "wheel should be within the validity period, resin and rubber bonded grinding wheel rotating storage must be approved by the test, those who pass the year before use." Texture problems with the process, if construction cutting blades‍ you find a local wheel cracks, should immediately stop using and re-replacement of the grinding wheel, grinding wheel to avoid crushing injury accident.

flat cutting disc Environmental issues

Environmental issues in general should set up a dedicated stainless steel cutting discs grinder wheel room, and is prohibited in the vicinity of the grinding wheel grinding machine room or stacked flammable items, to avoid fire or explosion, nor should other parts or misplacing items around the grinder. Management grinder should be someone responsible who want non-unit personnel when the grinding wheel machine object, subject to a full-time person in charge of licensing and strict compliance with safety rules, is prohibited without the consent of the responsible officer, unauthorized outsiders mess with grinders. In addition, the replacement of the wheel should also be the person responsible, to prohibit others from unauthorized replacement, installation of wheel. Off the problem of car stops working after the operator should immediately turn metal cutting wheels‍ off the car. Grinder is prohibited in the absence of the use of idling, unattended situation. Furthermore, it should be kept clean shortwave turbine after use.
