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

Corundum for a variety of carbon and alloy steel processing in general; corundum than corundum hardness, brittleness, grinding heat is small, because of its high price, hours of thermal deformation of the workpiece with the requirements, but also used as an abrasive mix in special materials processing; black corundum low hardness, cutting force is poor, but the prices are cheap; black silicon carbide high hardness and brittleness good, sharp cutting edge, good self-sharpening performance, good thermal conductivity, in processing non-ferrous metals, plastics, rubber, and cast iron and other aspects have the advantage.

Influence the shape of cutting wheel, balance cutting performance

Influence the shape of cutting wheels, balance cutting performance:
(1), large thickness, cut slit width, wheel consumption; when the strength of the guarantee, the thickness as small as possible, saving wheel material is cut and save material; flat shape of large, slit width is determined by the thickest , but the intensity is determined by the thinnest, stone cutting wheel wear large and vibration, it will affect the entire cutting process. Wheel can be made thin in the middle, surrounded by thick is physical status.
(2), when the wheel runout is large, at the beginning of the cutting vibration, could easily lead to wheel off the block, on the strength and cutting, but cutting automatically after finishing a smaller overall impact.
(3) When the wheel side to beat the big time, cutting back and forth, cutting width large. Cut unnecessary material consumption, grinding wheels consumption naturally big, big impact.
(4), when the imbalance in the cutting vibration, could easily lead to wheel off the block, the impact strength.

Tile cutting wheelswidely used in a lot of cutting and metalworking sectors

Tile cutting wheels widely used in a lot of cutting and metalworking sectors slotting process to achieve the thinnest 0.1 mm, it completed the general saw cutting blades can not complete the processing tasks, especially high-speed enhancement after cutting discs are widely used, cutting Wheel requirements increase rapidly. In the grinding process, the surface roughness is conducive to meet higher demand. In the machining process, the grinding and polishing processes more use resin bonded grinding wheels, grinding under the same conditions, the resin abrasive finish higher than ceramic abrasive.

Cutting wheels molding include

Cutting wheels molding include: hot, cold, rolled three methods. Thermoforming law required little pressure. Molding density, high hardness, good strength; Northern China multi-pressing method; the advantages of cold pressing method is not required when the heat source for various combinations of abrasive agent; multi-use cold southern China, France; rolling law to be energy small, green density, low efficiency, are less common. Generally without reinforcing sheet wheel and export network in Bo resin sheet grinding wheel.
Cut off wheel hardening temperature is too low, too high, the holding time is too short, too long and are on the cutting performance disadvantage.

Best results of cutting wheels cutting conditions

Best results of cutting wheels cutting conditions:
1. The grinding wheel cutting line speed must be greater than 80 m / sec;
2. The grinding cutting tools must be water cooled cooling water flow is not less than 2.4 l / min;
3. The grinding wheels cutting depth is determined according to the thickness and cutting material. Usually within a maximum cutting depth of 3 mm;
The selection of films wheel, in order to ensure optimum cutting results, depending on the cutting material should select the appropriate grit size of the grinding wheel.

Improving the performance of the grinding wheel

Improve the performance of the abrasive surface and interface between the resin and bonding to improve bonding capacity, improve the mechanism of the mixing process and the performance of the grinding wheel. By heating, vacuum means of abrasive treatment to obtain a clean surface; for abrasive cutting wheels test results prepared by orthogonal experiment data processing and variance analysis, the results showed that: vacuum and heating can improve grinding wheel performance, vacuum pumping effect in improving the performance of the grinding wheel is more pronounced. By evacuation and heating can improve the surface between the abrasive and adhesive resins - Interface performance, enhance its bonding capacity, improve performance grinding wheel.

Cutting wheel must be carefully checked

Cutting wheels must be carefully checked and identification prior to installation. To check the identification of:
1. Check the wheel grade is correct, it meets all the selection grinding wheel performance, shape and size.
2. Check the appearance of the structure and differential wheel situation. With the eye whether the appearance of damaged wheel (or cracks). The appearance of damage (or crack) the wheel can not be used. Another requirement wheel ends flat surface, no obvious skew.
3. Check the grinding wheel and differential internal cracks. By hand and wheel, grinding wheel with a wooden hammer tapping hear its sound, no crack crackled wheel, the wheel is cracked hoarse voice, which can not be used.

High strength cutting wheel

Resin binder is an organic binder, this binder manufactured high cutting wheels strength, has a certain flexibility, low heat resistance, good self-sharpening, easy to manufacture, process cycle is short. Work can be produced faster than 50 m / s wheel and thin wheel. Its scope of application after the vitrified widely used rough grinding, snagging, cutting and grinding freedoms, such as grinding steel ingot casting deburring and the like. Can manufacture high-speed, high-quality finish grinding wheels, heavy duty, cutting and grinding wheels of various special requirements.

Granite cutting disc wear problems

Any granite cutting disc has its requirements for the use of certain wear, the wear reaches a certain level it is necessary to replace the new disc. Not in order to save material, it requires the use of ultra-wear, which is a very unsafe violations. A general rule, when the cutting discs wear to chuck diameter larger than the diameter of 10mm it should be replaced with a new disc. Validity of the problem from the Treasury brought a new disc is not necessarily qualified disc, new disc even buy from the manufacturers are not necessarily qualified disc. Any disc has its certain expiration date, in the effective use of the term, it is qualified disc; use over the period, it is not necessarily qualified disc.

Cutting wheel design

Grinding wheels designs should be considered in addition to grains, it must also consider the diamond / CBN cutting discs and SiC / Al2O3 cut difference between the sheets. Due to high grain hardness and fixed with a durable adhesive abrasive, diamond cutting wheel CBN / performance is very durable. Metal disc periphery (continuous rim) just stick a thin layer of abrasive. These are long-term consumable cutting wheel cutting disc. SiC and Al2O3, and other abrasive, wear relatively fast, relatively inexpensive. Thus, the entire body of the abrasive grinding wheel and a binder. This cutting wheel is called the consumable cutting disc.

Select grinding wheel wheel

According to the material to be cut, you may need to use a grinding wheel with different ingredients. Grinding wheel is also affected by the choice of material hardness and toughness. Split carbide ceramic or diamond bonding material need to use adhesive made from metal or Bakelite cut plate.
Bakelite adhesive bonding using aluminum oxide (Al2O3) grinding wheel is a typical choice cut of ferrous materials. Cubic boron nitride (CBN) is also increasingly used in high hardness cutting ferrous materials. Non-ferrous metal grinding should be chosen by the phenolic adhesive bonding of silicon carbide (SIC) grinding wheel.

Defined wheel strength

Abrasives include tensile strength, flexural strength, compressive strength and resistance to funk strength. Strength is the maximum tensile stress being under tensile performance abrasive abrasive, it is abrasive manufacturing, a secondary indicator of use, direct and abrasive is being high speed winding can rupture strength. Abrasives abrasive performance flexural strength maximum bending stress or bending limit promise. Is being abrasive grinding for molding 9 _ way, such as thread grinding, crankshaft grinding and all kinds of plunge grinding, require grinding deposit is being better flexural strength to resist when grinding attack bending stress. Abrasives compressive performance is being abrasive ultimate strength under pressure, such as being flap disc for stainless steel _ blunt fracture and rupture may be the extent of it and the compressive strength is being increased radial load grinding. Anti-funk performance abrasives abrasive strength is being fixed RESISTANCE funk force under load. Abrasives abrasive strength comes from the manufacturing process, the factors linking agents and abrasive performance specifications repercussions abrasive strength are: _ abrasive type, size, variety and performance of the coupling agent, abrasive stance use, organization, density, mixing and heat treatment conditions, abrasive shape, and the aperture ratio of the outer diameter of the wheel. Process is being abrasive characteristics and specifications given current, the coupling agent performance and heat treatment conditions on the most minor of.

Wheel of successful high-speed wheel dressing tips

Wheel good repair skills to the greatest increase grinding wheel performance is a key factor in good shaping and dressing (known as trimming) tools and skilled finishing techniques. In fact, a high quality dressing wheel dressing tools and techniques to master operator can always keep grinding wheel with high performance. Rather than just relying on purchase so-called good wheel. This is very important because the plant can not operate in every individual case, with a special wheel. Dressing is an ultra hard abrasive grit grinding wheel sharp process. In this process, the need to remove the binder and abrasive grains blunt wheel between the flap discs has a strong abrasive grinding performance than outstanding binders to form a sharp cutting edge. Sharpening wheel must be from the surface of the pores, remove small materials, preventing the force acting on the metal cutting wheels on the increase, the grinding wheel on the force increases, will cause vibration and burns caused by parts of the surface.
Without proper dressing, even the best can not get high quality and wheel size consistency machined parts. In fact, when you invest in the quality of the wheel, in order to obtain a high grinding performance, good trimming them is very important.

High-speed grinding wheel classified information

Grinding wheel classification

Grinding wheel variety.
Press the abrasive can be divided into ordinary abrasive (corundum and silicon carbide, etc.) and natural ceramic diamond disc and superabrasive (diamond and cubic boron nitride) grinding wheel;
According to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel, tile granite cutting wheels, disc wheel and so on; by binding agent can be divided into pottery wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters of the grinding wheel abrasive, grain size, hardness, binding agents, shape, size and so on.
Since the wheel typically operate at high speed, before turning test should be carried out so that the use of (guaranteed at the maximum operating speed of the wheel, do not break) and static balance test (when working to prevent vibrations caused by the machine). Grindstone at work for some time, it should be trimmed in order to restore the grinding performance and correct geometry.

Special introductory wheel transport situation

1, the metal grinding disc must complete packing and shipping and collision avoidance can not be long-term bare moisture, does not contact with the bases;
2 wheel neatly stacked in flat way, not long diagonal and pressure, prevent deformation;
3, avoid direct contact with the ground, must Gechao wooden pallets stacked with care, 10-15cm ground clearance is appropriate, stacking height of not more than one meter;
4, first with the implementation of advanced principles to ensure the best use of the product;
5, the product may use more than one year should be re-tested after rotation strength and appearance.

High-speed grinding wheel hardness

Domestic and international data show that high-speed grinding infeed amount than ordinary grinding doubled. Better conditions for cooling high speed cylindrical grinding, the infeed amount than ordinary grinding infeed amount slightly increased a little. In developing this specification, the amount of selected infeed infeed grinding in general within the range of 1.52 to the amount of times.
No feed diamond polishing cup speed V at the time of sand to improve the conditions, make the contact time of the grinding wheel and the workpiece becomes shorter, so that the elastic deformation of the workpiece will be reduced, thereby eliminating the time of elastic deformation of the workpiece will be reduced.
Therefore, compared with the conventional grinding without feed grinding time, no time should be shorter feed grinding at some of the high-speed grinding.
Centrifugal wheel wheel operation is selected as F = mV2 sand r (2) From (2), the centrifugal force is proportional to the square of the speed V and the wheel sand. When the wheel speed increases from 35m / s to 60m / s, the centrifugal force will increase 2.93 times, which requires high-speed grinding wheel should have sufficient strength at that high speed grinding wheel binding agent should have sufficient bonding capacity . Therefore, when selecting the high-speed wheel-binding agent in the choice of the adhesive ability of vitrified (V). Workpiece material to be ground due to hardened bearing steel GCr15, abrasive should use strong anti-burn ability, toughness large brown corundum (A) and white corundum (WA) mix. High-speed bench grinder wheels hardness than ordinary sand 185 wheel bearing 62001.l.6 hardness 12, so not only can increase the intensity of the grinding wheel, and can meet the requirements of high efficiency, high durability. High-speed grinding wheel size should have better formability than ordinary wheel size fine 12.

. f wheel rotation speed is high, the tile cutting wheels hardness optional software 1-2 small stage;
g. high hardness dry grinding wheel coolant used during grinding than 1 to 2 hours class.

Cutting grinding blades

Manufacturers typically offer diamond blades at various quality and cost levels, ranging from basic economy to top-of-the-line premium or professional versions. Generally the key difference among these options is the diamond content, which is the greatest raw material cost in manufacturing the blade. Moving up from a standard to a premium blade may boost the cost 20% or more, but you'll get a higher construction cutting discs and significantly longer blade life.
Basically, you need to decide what's more important: the initial cost of the blade or total sawing cost. For small cutting jobs where you won't be giving the blade much of a workout, you may save money by going with the economy blade. For large jobs or frequent use, a top-quality blade may actually be less expensive in the long run based on a cost-per-cut breakdown.
A premium-quality diamond reinforced conrete isn't cheap. Expect to pay several hundred dollars or more, depending on the stainless steel cutting wheel. If that's more than you're willing to invest for an occasional cutting job, consider hiring a professional sawing contractor to do the work. To locate a contractor in your area.
