Resin grinding wheel manufacturing process of introduction
 Resin wheel with good elasticity of shock, shock, lateral pressure sensitivity of small advantages. The next Xiaobian to introduce resin wheel production mixing process. As follows:First abrasive grain size is typically mixed for pre-mixing, and then adding the wetting agent, even after wetting the abrasive, and then has to be mixed with other particulate fillers good powdery resin is added, and mixing continued until homogeneous. Good to have a good mix of abrasive plasticity and mobility, material can not be too wet, or easy to agglomerate, but can not have the dough, while ensuring good liquidity to ensure adequate injection molding, commonly used screening approach remove lumps. Resins are generally considered to be a normal metabolite plant tissue or secretions, and volatile oil often exist in the plant secretory cells, resin ducts or conduits, especially perennial woody parts of the catheter heartwood. A mixture composed by a variety of ingredients, usually amorphous solid, surface slightly shiny, hard and brittle, a small number of semi-solid. Insoluble in water, nor swelling, soluble in alcohol, ether, chloroform, etc. Most organic solvents. Heated and softened, and finally melting, burning smoke, and have a special aroma or odor. Natural and synthetic resins into two categories.The importance of resin grinding wheel manufacture one kind of demand for larger tool. It is the use of benzoic acid and polyamide, or other resin as a binder, by the diamond or cubic boron nitride abrasive glued with an inorganic filler made ​​of a tool. This tool is currently being effectively used in various grinding operations, such as surface grinding, cylindrical centerless grinding, grooving and internal grinding and so on. It is used for super alloys, cermets, ceramic products, glass products, limonite, high speed steel, alloy tool as well as many other new superhard materials ideal grinding tool.

Resin wheel scrap reasons and measures
1, the material does not match the size, hardness match. Measures: single-ingredient calculated strictly according to the ingredients, is a key program review;  2, mixed. Before mixing with the mixing process, with tooling equipment into the cleanup. Ingredients, first check whether the impurities of various raw materials;  3, mixing uneven. Mixing mixing time according to process requirements. Replace any worn parts too big blender. Powdered resin material according to process requirements and frequency of screening mesh number;  4, tissue heterogeneity, uneven hardness imbalances. Adjust the mix dry humidity, it has good formability. Amortized according to process requirements for materials and scraper operation. First with horn according to process requirements, maintaining the accuracy of the press; when feeding material scraper unevenly spread, mixing humid, or material agglomerate, feeding inequality, die wear, leakage of material seriously, need to replace the mold;  5, forming adobe cracks. Pressing temperature is too high, the product thermal shock, de-core when the temperature is too low, should be de-core type, raw material moisture deterioration, or with mixing errors; 5.1 end cracks. Molding material plasticity is poor, improper discharge mode to take blanks. Mold base plate is not parallel uneven or too large. 5.2 peripheral cracks. Badly worn die sets, die sets when unloading is too skewed. 5.3 aperture cracks. Blank low intensity, unloading mold too much vibration, wear too big or taper mandrel is too small, the order does not match the mold unloading process requirements. 5.4 pairs of corner cracks. Optional spring horn, leaving the mold deflection elastic compression produces inconsistent diagonal pattern. Fine abrasive Liaoduo suppress excessive speed, maintain the pressure a short time, the mold with the gap is too large. 5.5 crack precautions: Speed ​​is good plasticity mixture, forming tooling shall not exceed the prescribed wear standard templates and horn maintain good flatness, the choice of the thickness of the horn, spring horn elastic to be consistent, according to the process prescribed order unloading mode;  6, the end faces are not parallel. Suppression of Taiwan to maintain the accuracy of the press, according to the technical regulations operation;  7, uneven surface. Tooling equipment maintenance within the required accuracy;  8, forming hardness match. Suppression of the first pieces will be seized, each consisting of not less than 30% of the sampling blanks, often check weighing unit weight, often observe whether the change in pressure;  9, the bridge flute uneven. Cooling requiring uniform; workpiece surface "warping" There is no flat surface called a bridge shocked. This is due to uneven cooling contraction leaving parts of the plate is inconsistent or uneven loading furnace caused. More from thin sheets and fine-grained sand wheel products.  flap wheel flakes easily when the cooling too quickly produce bridge flute waste;  10, blistering. Hardening curve by product specifications for controlling the temperature hardening of the mixing process with strict quality control; molding temperature is too high or too low, you need to adjust the temperature. Curing temperature, curing oven temperature is out of control. Binders mismatch; superhard abrasive localized deformation or the entire surface of the convex surface of the expansion, and was shiny resin, with some turtle-shaped cracks. Cause: 10.1 warming up too fast or temperature fluctuations, easy to make fine grain size, hardness, organizational tight parts blistering and swelling. Because this type of multi-dose combination product containing or porosity is small, if the temperature control is not exactly the heating rate is too fast, it will cause fierce response binding agent, the amount of volatiles surge adobe products leaving the internal gas pressure, blistering and swelling. 10.2 uneven mixing type material, the material has a binding agent pimple or contain more low boiling point solvent (such as ethanol, acetone). 10.3 mixing, molding process error caused by the parts combined dose increased, unit weight increases, the pressure increased and so on.
wheel in use ten notes
 Wheel Caution:A  grinding wheel  should be checked before installing the fan, to see whether there are cracks and percussion hammer with a wooden wheel and listen to whether there were unusual voiceless, and if so, the cooling fan can not be used in order to avoid the consequences of injuries caused by broken wheel.2 newly installed or every other day using wheel, you should use idle more than a minute and then, if everything is normal, you can follow the grinding machinery related to safety regulations.3 due to wheel brittle and fragile, do not let by the impact, collision, but can not fall. Storage should be frost, moisture, keeping cool and ventilated room, placed flat, stacked neatly against dust, remains unused wheel cleaner, non-stress.4 wheel installation, you must find positive wheel center, but should be fastened with flange, flange mounted on the wheel should be checked after any discussion with the spindle concentric cylindrical grinding wheel with at least one side of the vertical centerline of the spindle.5 After installing wheel, for safety reasons, do not pass protective cover must be installed properly, and then start the machine to use.After doing the above steps, the wheel can be used. It should be noted when it is used:1 wheel speed shall not exceed the safe operating speed.(2) does not specifically use the wheel face work, do not work with grinding wheel face.3 workpiece during grinding wheel, do not push the workpiece leveraged to increase the pressure on the wheel.4 wheel dressing dressing tools should be used exclusively. Trimming, the operator must wear protective glasses.5 In the grinding process, should be the correct selection of the coolant; coolant if not, there must be dust-proof devices.6 Use the wheel customers, should be familiar with wheel installation, operation process.
