structure
Diamond wheel construction work generally consists of layers, substrate, buffer layer composed of three parts.
Working layer, also known as diamond layer, made of abrasive, binder and filler, is working part wheel. Also known as non-diamond layer the buffer layer, the binding agent, metal powder and a filler, is fixedly connected to the part of the diamond layer on the substrate.
Substrate for receiving the abrasive layer, and when used with a flange securely held on the grinding machine spindle. General metal binding agent selected steel products, alloy powder as a matrix; resin binder be aluminum, electrical wooden base. It made of aluminum, steel or bakelite processing, support from the working layer and chucking abrasive effect. The quality of the grinding wheel molding and use of precision level and the substrate are a great relationship.
characteristic
Characteristics include a wide diamond wheel diamond abrasive, particle size, density, size and shape of the binding agent.
use
Since diamond abrasive with the characteristics (high hardness, high compressive strength, wear resistance), making it an ideal tool for diamond abrasive grinding hard and brittle materials and carbide in grinding, not only high efficiency, precision high and good roughness, abrasive consumption, long service life, but can also improve working conditions. Low iron content of the metal and non-metallic hard and brittle material is widely used in ordinary abrasive difficult to process, such as carbide, alumina ceramic, optical glass, agate gem, semiconductor materials, stone and the like.

What type of abrasive Grinding wheel is?

Grinding wheel is to add a binder in the abrasive, the porous body through compacts made of dried and calcined. Due to the abrasive, bond and different manufacturing processes, characteristic differences between the grinding wheel is large, so the grinding process quality, productivity and economy have an important impact.

Characteristics of grinding wheel is mainly determined by the abrasive particle size, binder, hardness, structure, shape and size and other factors; abrasive wheel is the largest amount, the most widely used method of using surface rotating at high speed when used, can be of metal or cylindrical, round, flat face and a variety of other non-metallic type workpiece roughing, semi-finishing and fine grinding and grooving and cutting and so on.

The press can be divided into ordinary abrasive abrasive (corundum and silicon carbide) abrasive grinding wheel and the natural and super abrasive (diamond and cubic boron nitride grinding wheel) wheel; according to the shape can be divided into flat-shaped grinding wheel, bevel wheel, cylindrical grinding wheel , cup wheels, disc wheel and so on; press binding agent can be divided into ceramic wheel, resin wheel, rubber wheel, metal grinding wheel. The main parameters of the abrasive wheel, viscosity, hardness, binding agents, shape, size and so on.

In the production process to use diamond grinding wheel on the belt, the general grinding wheel is necessary to remove the cleaning operation for 5-7 days, there is grinding down rubber crumbs above, after the high temperature friction and firmly attached to the diamond surface, it is difficult cleaning.

Cleaning requirements: (1) to environmental protection, non-one can not be a halogenated hydrocarbon. (2) can not damage the diamond grinding wheel.

Gringding Wheel In Mechanical Descaling

This method is currently applied widely as a descaling method, the principle is the use of impact and friction effectively remove rust and dirt. This method is commonly used in portable electric Grinding Wheel, electric brush, brush pneumatic, derusting guns. The advantage of this method is that rust quality, efficiency are high, but the drawback is that these tools also require manual operation, greater labor intensity of geometrically complex parts and precision is not applicable, not suitable for large-scale blasting needs. It is more extensive or spraying and blasting two treatments rust dirty methods currently applied.

(1) This method is mainly blasting sand blasting, shot blasting, vacuum blasting, high-pressure and high-pressure water, sand and water.

(2) This is a high-speed shot blasting iron pellet (pellet or other materials) the impact of a use of high-speed rotating impeller blast wheel thrown, with the friction between the parts of the surface to clean rust and achieve the purpose.

How to prevent the broken 2 wheel in the idling

In grinding operation rules have a provision, requires the operator to install new grinding wheel before grinding should let it idle for a few minutes, the purpose is to observe the possibility of broken. Wheel the reason why the idling broken, mainly because it in the rotation of the front has a crack. Therefore, the prevention of such broken should be to prevent the wheel in the transport, storage and installation of the cracks.

2.1 correct grinding wheel transport mode and method

(1) long distance transport, handling should be complete package, available has no significant impact on the environment of soft materials will wheel fully infilled, to prevent the handling process of vibration and impact.

(2) short distance transport:

A. handling to prevent the wheel from falling or hit by the impact of such impact;

B. must scroll, to spread on the ground to buffer wood, rubber or straw bags such as, in the gently rolling;

C special heavy grinding wheel should be used when handling special handling tools, the use of tools should be equipped with soft materials of the liner, the vehicle should be equipped with inflatable tires.

However in the practical work, we can often see short distance conveying wheel in did not take any protective measures, in the factory on the road rolling wheel, a solid wheel cart to transport the wheel (especially in the trenches cut grinding wheel), they are ignoring wheel transport regulations on the storage, irresponsible to the personal safety of the operators, safety accident hidden trouble.

2.2 correct grinding wheel keeping method

(1) the requirements of the storage environment:

A. grinding wheel should be placed in a dry, temperature change is small, and the room temperature should not be less than 5 degrees celsius;

B. where there is no vibration;

C rubber bonded grinding wheel can not contact with oil, resin bond wheel should not be in contact with alkali;

D. rubber bonded grinding wheel and resin bond grinding wheel storage temperature is best at 5 degrees 20 degrees Celsius, the relative humidity should not be greater than 60%, to avoid direct sunlight and close to the heat sink, drainage device.

(2) requirements for storage space and manner

A, the wheel should not be piled up at random, should be stored within the appropriate stent, cabinets or drawers, should be in accordance with the specifications are placed separately, storage should be with signs, in order to avoid confusion and error.

B. placement method should be considered the shape and size of the grinding wheel, the larger diameter or thickness of the grinding wheel should be upright or slightly inclined placed, thinner and smaller grinding wheel should be stacked, but stacked height not more than 60 a 500 0mm;

C. small wheel diameter (diameter 50 mm below) be used rope on the safe, bowl, cup and saucer shaped wheel should be to the bottom face under a stack, but placed height can not be too high.

D. rubber or resin sheet grinding wheel stack height to below 200 mm, and in the upper and lower put a flat iron plate to prevent deformation of the grinding wheel, with the sharp edge of the sheet wheel shall be stacked and in the middle pad to pad thick paper or other soft material);

E. resin bond, rubber bonded grinding wheel in the process of storage, the bond will be aging to reduce its strength, so the storage period of the grinding wheel generally can not be more than one year. The grinding wheel must be re examined before it can be used after the storage period;

To ensure that vehicle braking performance wheels for processing

To ensure the car has good braking performance, both end surfaces parallel to the brake disc requires a degree of 0.005mm, roughness Ra <0.4μm, both end faces have decorative patterns. In order to ensure equal thickness, parallel and decorative patterns, it requires the use of a fixture pole while turning both end faces, and then double-wheel grinding process while double-end, so far there are no suitable special machine. Manufacturers can only be used after the completion of the common procedure modernization of machine tools, precision machining it is not only low, low efficiency and poor security, labor-intensive. Due to the required accuracy, processing of products barely into two international auto parts market, can not be directly supporting the world's leading automobile manufacturers.

Proper installation and use of the grinding wheel

  It should be carefully checked before installation of the grinding wheel without deformation, hoarse voice, cracking and the maximum line speed indicated whether the angle grinder is consistent with a cutter speed, error-free after installation should confirm mounted flat disc Kafa Lan degree and diameter and gasket meets the requirements. When the ban solid wheel, only allowed to use the specific manual wrench, prohibited the use of clamps or supplement beating tools.

  When tightening, pay attention to the tightness of the nut or screw fastening wheel drive is not enough to produce the degree of slip is appropriate to prevent the tightening force caused by excessive wheel breakage. After tightening the flange after installation Put the protective covers, the operator sideways and rotational direction of the grinding wheel and a certain angle commissioning of power for 30 seconds, no abnormality can be put into use. When using the technological requirements should control the amount of feed can not be forced to feed and impact wheel

Binding agent questions about the abrasive wheel

1) unstable quality resin, the resin of free phenol content fluctuated. That so-called residual free phenol in the resin of phenol, the formula C6H5OH, make long-term heating cleaved from the resin hardened, the impact strength of the wheel;

2) resin powder mixed with hexamine uneven school called methenamine hexamethylene tetramine ((CH2) 6N4), as the resin hardener, methenamine insufficient amount is added, the resin is not cured complete wheel impact strength and hardness; content is too high, the excess hexamine does not bind to the resin, volatile decomposition in the hardening process, the grinding wheel pores increase, reducing its strength and hardness. Hexamine resin powder and uneven mixing, the consequences of high levels of low ie methenamine harm;

3) binding agents granularity is too coarse, the general view size binder to fine is appropriate, which is conducive to the bonding agent is distributed uniformly in favor of hardener full contact.

The particle size is too coarse, the molding material is difficult to mix uniformly, impact strength and hardness of the grinding wheel. Even for coarse-grained resin sheet cutting wheel and cymbals shape grinding wheel in terms of its choice of binder (resin powder) particle size should be finer than 320 #. Wheel manufacturing granular product size requirements for the binder a few microns.

Broken two reasons leading to the wheel
Date: 2012-06-08
First, the linear velocity is too big wheel1, when the rotational speed of the wheel shaft is too high, control wheel shaft speed to achieve their desired comply with the requirements of the processing speed.2, wheel diameter is too large .. Date: 2012-06-08

 First, the linear velocity is too big wheel

 1, when the rotational speed of the wheel shaft is too high, control wheel shaft speed to achieve their desired comply with the requirements of the processing speed.
2, grinding wheel diameter is too largeWheel diameter is too big line speed will be big, this time to rationally adjust the wheel speed, to match processingRequirements; or using smaller diameter grinding wheel to be processed.
Second, the work is often caught between the grinding wheel and the workpiece holder
1, there is no established side grinding workpiece carrier side grinding is performedFlat-shaped grinding wheel ban for side grinding wheel side grinding bowl should be used for processing. To correctTo set up workpiece holder.
2, the workpiece holder and the workpiece support wheel adjustment bad interval between these two sides to adjust to less than 3 mm, the gap is too large will cause the workpiece card phenomenon. Unfortunately, it would cause the wheel to break.

 3, between the workpiece and the workpiece support tough load wheel support of the workpiece by the workpiece holder can not be tough mount between the grinding wheel and workpiece holder.

V-groove forming Grinding wheel

balance scaffold made of high quality material for the balance shafts, the heat treatment and high precision machining and assembly therefore precision, stable performance is an ideal machine tool accessories. larger than 125mm diameter wheel must be balanced so that its center of gravity coincides with the axis of rotation of the wheel.Unbalanced wheel at high rotational vibration occurs, affecting the processing quality and precision machine tools, it can also cause serious damage to the machine and wheel fragmentation. Caused by an imbalance of the original storm largely uneven density portions of the wheel, asymmetric geometry and installation eccentricity. Therefore, before installing the wheel must be balanced, the balance wheel static balance and dynamic balance are two kinds. Under normal circumstances, just as static balance, but in high-speed grinding (speeds greater than 50m / s) and high speed grinding, it must be balanced.When the balance wheel mounted on the mandrel balance, then install the kind of wheel axle flat onto the balance wheel balance rail bracket, the wheel will swing back and forth, until the swing stops. If the grinding wheel imbalance, it always goes below the heavier portion. In this case the position of the movable balancing blocks to reach equilibrium.

Factors which can affect the grinding wheel speed

Grinding has a long history, with the emergence of a large number of fresh material and application has brought an unprecedented breakthrough for the future of the show. Diamond grinding process is a more complex process, multivariable interaction process, always changing them, diamond grinding wheel is removed quantitative workpiece material to obtain a higher surface quality and precision.

Wheel speed on the line is more complex when the wheel was increased from 28.8m / s to 33.6m / s when the speed increased only 16%, while the blocked amount increased threefold. Because of the increased wheel speed of the abrasive grains of the maximum depth of cut is reduced, chip cross-sectional area decreases, while the number of cutting and grinding heat increased so that clogging increases. But when high wheel speed to a certain extent (eg reach 50 m / s or more), the amount of clogging wheel but declined significantly. So choose the best to avoid wheel speed 20m / s to 50m / s this speed grinding.

Practice has proved that diamond grinding wheel speed to prepare, wheel loading increased threefold, so the higher the speed of the workpiece, abrasive load rain, abrasive cut more shallow depth, the cutting cross-sectional area decreases, while grinding thickness increases, heavier abrasive passivation, increase the grinding wheel on the workpiece extruded layer, a diamond wheel corresponds to harden characteristic change occurs, thus resulting in the clogging of the grinding wheel.

Wheel size, hardness, structure and wheel speed grinding methods to optimize the grinding process to establish a reasonable grinding parameters and summed up the law, it is an effective way to guide the production, but also grinding technology research should focus on the content.

Grinding Wheel for polishing

What Are Superabrasives?

Superabrasives make up a special category of bonded abrasives designed for grinding the hardest, most challenging work materials.

Because carbides, high speed steels, PCD, PCBN, ceramics and some other materials used to make cutting tools can be nearly as hard as conventional abrasives, the job of sharpening them falls to a special class of abrasives-diamond and the CBN, the superabrasives.

These materials offer extreme hardness, but they are more expensive than conventional abrasives (silicon carbide and aluminum oxide). Therefore, superabrasive grinding wheels have a different construction than conventional abrasive wheels. Where a conventional abrasive product is made up of abrasive all the way through, superabrasive wheels have abrasive on the cutting edge of the wheel that is bonded to a core material, which forms the shape of the wheel and contributes to the grinding action.

Superabrasive wheels are supplied in the same standard grit range as conventional wheels (typically 46 through 2,000 grit). Like other types of wheels, they can be made in a range of grades and concentrations (the amount of diamond in the bond) to fit the operation.

There are four types of bond used in superabrasive wheels. Resinoid bond wheels are exceptionally fast and cool cutting. They are well-suited to sharpening multi-tooth cutters and reamers, and for all precision grinding operations. Resin is the "workhorse" bond, most commonly used and most forgiving. Vitrified bond wheels combine fast cutting with a resistance to wear. They are often used in high-volume production operations. Metal bond wheels are used for grinding and cutting non-metallic materials, such as stone, reinforced plastics and semiconductor materials that cannot be machined by other cutting tools. Single-layer plated wheels are used when the operation requires both fast stock removal and the generation of a complex form.
