Honing machine produces residual stress is what causes
abrasive cloth belt   produces residual stress is what causes? It noted broaching, honing machine when cutting the inner surface of the metal layer in the processing of plastic deformation occurs, so that the surface of the metal increased hematocrit. Only due to plastic deformation of the metal surface, the metal surface is increased and the specific volume, the volume expansion is inevitable to be blocked in the metal layer is connected with it, and therefore the surface of the metal layer to generate residual stress, and in generate a residual tensile stress in the metal layer.According gear chamfering machine understanding cutting, the cutting area will be a lot of cutting heat generated. Different microstructure having different densities, also have a different specific volume. If the metal in the surface layer microstructure changes, changes in the specific volume of metal bound to the surface is hindered base metal connected thereto, and thus there is residual stress.
Determination of resin abrasive formula
Accurately measure the finished recipe abrasive cloth belt research, design, development plays a decisive role, but artificial test data to calculate complex and cumbersome and error-prone, to make abrasive formula becomes simple and accurate measurement, easy one article on computer-aided measurement ordinary resin abrasive finished formulations preliminary exploration. Abrasive formula is based on the manufacturing process, is the key to the production of abrasives. Abrasive formula prescribed ratio of abrasives, binders, fillers, coloring agents of raw materials, feeding unit weight, molding density and other parameters, the decision abrasive performance. Unknown to the finished abrasive formulations were determined formula, mainly for the development and design of products, developed with its own characteristics abrasive products. Determination recipe can be used for abrasive waste analysis, waste generated guide to find the causes and solutions, to create a product to meet user requirements.
Vitrified bond diamond abrasive applications the problems
Because the characteristics of the diamond , making it to the performance of ceramic binders have special requirements , and therefore the current domestic vitrified diamond grinding tools have not been widely used. Mainly for the domestic diamond  abrasive cloth belt  binder resin and metal , vitrified bond amount is also small.The main reason is : 1 ] due to the production of diamond abrasive low temperature bonding agent , in order to reduce the refractoriness , combined with the introduction of a large number of basic materials agents , so the resulting low temperature ceramic binder , its performance ( low refractoriness , low thermal expansion coefficient , strength, etc. ) is difficult to control ; [ 2 ] during manufacturing, since the inert superhard material , the bonding agent bonding the abrasive grains and the wetting ability, the binding agent reduces the bonding strength of the abrasive grains , grinding when grinding tools , abrasive falling fast , wear big ; [ 3 ] in the grinding process , due to the brittleness of ceramics , abrasives in the use of impact resistance , fatigue resistance are poor, easy to use embrittlement phenomena occur , thus affecting the characteristics of abrasive grinding and poor thermal conductivity of ceramic grinding area of high local temperature , so that heat loss is easy superabrasive grains also affect abrasive grinding characteristics . This directly affects the vitrified bond diamond abrasive used.
Mesh and pocket the difference Shabu
Chinese name translation : English translation mesh name: Glass  abrasive cloth belt  is made ​​by weaving , the coating material is subjected to surface treatment using a grid -like braid. Item Unit Technical performance indicators / ( standard mesh ) mesh center distance MM 4 ~ 6 mass per unit area of ​​the fracture strain G/M2 ≥ 160 % ≤ 5 Alkali breaking strength retention ( warp and weft )% ≥ 50 Alkali breaking strength retention value N/50MM ≥ 750 alkali wave fiber network across the fabric ( gel content )% ≥ 8 alkali -type wave fiber network across the fabric ( gel content )% ≥ 20 emery cloth ( paper ) shabu (zhi) emery cloth ( paper ) abrasive cloth or paper with adhesive to adhere to the abrasive cloth or paper -like substrate coated abrasives page . Emery cloth and sandpaper is coated abrasives in a long history, the largest amount of a kind widely used in a variety of hand- sanding operations. Emery cloth ( paper ) standard specifications for the 230 × 280 mm, dry grinding , water , gold equal to the principal varieties. ① dry scrub cloth : also known as sand paper to cloth as matrix to gelatin as a binder to corundum abrasive made ​​, mostly for rust and polishing metal materials , but also for sanding wood. ② dry sanding paper : also known as wood sandpaper to paper as the substrate to gelatin as a binder , glass sand or natural sand abrasive just made ​​more for sanding wood. ③ waterproof sandpaper : paper as a substrate to varnish binder to green silicon carbide abrasive corundum or made ​​of metal used for polishing and sanding paint putty . ④ metallographic sandpaper : the paper as the substrate, adhesive resin as a binder to make abrasive silicon carbide powder is made more for metallographic grinding and polishing precision . Variety of emery cloth ( paper ) their use can be made of different size requirements for different products to abrasive grit that their thickness.
