Grinding wheel dressing? Jiaxing bearing group co. , LTD

There is rotational, have HRB bearing ( ) Grinding wheel dressing? Jiaxing bearing group co. , LTD. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. With grinding wheel dressing tool grinding wheel working surface has a dull surface take go to, to restore the geometry of the grinding wheel cutting performance and the correct process, known as the dressing of grinding wheel. When grinding wheel in use after a period of time, will in the process of grinding wheel grinding wheel working surface grinding grain under the effect of friction, extrusion, it gradually rounded edges and dull, or when grinding material toughness, abrasive dust often embedded in the pores on the surface of the grinding wheel and the grinding wheel surface jams, finally make the loss of grinding wheel cutting ability. At this time, between grinding wheel and workpiece produces skid phenomenon, and may cause vibration and noise, bring down the grinding efficiency, surface roughness. At the same time due to the increase of grinding force and grinding heat can cause deformation of workpiece and grinding precision, serious when still can make grinding burn surface and small cracks, so this needs to dressing grinding wheel working surface. 1, diamond knife cutting method: is the diamond welding on large particles on the special tool rod. The tip of the diamond grinding into a 70 - 80° Angle, dressing grinding wheel abrasive diamond solid Angle, will break formation micro blade. This method is a kind of widely used. That should be paid attention to when using diamond dressing grinding wheel knife from several aspects: 1) , should choose the size of the diamond particles according to the diameter of the grinding wheel. In general, grinding wheel diameter & phi; 100 mm, optional 0. 25 - carat diamond; Grinding wheel diameter & phi; 300 - φ 400 mm, can choose 0. 5 - 1 carat diamond. 2) , because the diamond is expensive, before the use should check whether the welding is firm, so as not to fall off. When dressing grinding wheel or intermittent for cooling, so as to avoid the diamond fracture. 3) Installation Angle, diamond generally take 10 & deg; - 15° The installation height is lower than grinding wheel, diamond center 1 2 mm, and the clamping wants firm, to prevent vibration or into the bond diamond grinding wheel; 4) , must choose finishing allowance according to the processing requirement. Coarse Hugh, turning and longitudinal feed rate may be increased; When finishing the opposite. General 2 - to do Three turning, and then without turning on reciprocating nap again; 2, diamond pen repair method: diamond pen is a relatively small particles or diamond powder, with a strong adhesive force alloy combination and made into metal tool rod. Based on the distribution of the diamond case, there are three kinds of diamond pen: layered, chain, diamond powder. Its usage is the same as the diamond tool, low requirements in some process can replace knife dressing grinding wheel, diamond but the diamond powder is mainly used for dressing pen fine-grained grinding wheel. 3, roller cutter roller method: cutter were multi-disc carburizing and quenching steel metal plate. Metal plate when its shape is pointed horn, finishing with grinding wheel high-speed rotation, and the grinding wheel surface rolling. This tool is used only for large plastic rough dressing of grinding wheel. 4, diamond roller grinding method: we also called king kong roller, uniform cementation is the small diamond grains on the roller body, generally USES the electroplating method, can be made more complex shapes, shape of roller is of high precision finishing. But the price is more expensive, only used in large batch and high value-added products grinding, general situation is generally not used. 24-hour customer service hotline: if you are more interested in jiaxing bearing the author introduced the industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: jiaxing bearing sourcing consultant LTD.
