Sawblade for high-grade import description. Grinding

时间 : 2020-06--22
      At present, there are many saw blades for the market of small factories, lapping manual workshop; Grinding of the blade just anterior horn, serrated simple rough treatment, the blade has changed the original perspective, saws, side Angle after Angle, and tooth room there is no processing conditions, polishing, after its processing is simply not true the products detection, calibration, etc. According to customer reflects our grinding fees taller; Grinding is longer wait for a circumstance, do an illustration, introduce our grinding process flow and testing technology, and related technical standard etc.    A. when we received customer's need, the first after lapping blade, establish the customer product folder, put all the blades in the warm water 50 degrees Celsius soak 30 minutes, then cleaning, derusting, except that preliminary intuitive handling adhesive, the inspection obvious flaw cannot again grinding products, after cleaning good customers Numbers, mark directly on return but zone, stay after completion to grinding product mailed to customers together.    B. and then used for Angle qianbanbiao, including tooth test anterior horn; Foot; Side Angle of detection (see whether have crack, missing Angle etc), then put the projector on 50 to 100 times, enlarge to determine the serrated blade Angle and the original wear; Such as tooth missing Angle is lesser, we can appropriate amount to improve the grinding, reduce customers' production cost.    C. if alloy, the need to change gear with Germany KAHNY automatic brazing machine for tooth exchange operations.    D. then saw blades stress calibration, this step is grinding sawblade critical processes; Needed by very experienced technician to complete in high-speed operation blades in external process, because, under the action of the stress has blade has changed, so it appeared saw road greatens; Rough surface etc. Phenomenon; Our stress adjustment in 2 times above all requirements; If can correction in standard range (refers to Japan and the production technical standard room saw blades, then into within next procedure, conversely, we will and customer contact, consult customer comments, such customer requirements, we are for precision lapping grinding, however, we might be in after the completion of the package, attach blade specific data that the deviation of the blades, etc. Our grinding first is to use Japan imports on diamond wheel granularity of 200 coarse grinding, next reoccupy 600 grit grinding wheel for precision grinding.    E. The next step is the vibration rate after the check, qualified by B paces again make final inspection processes, and fully qualified after delivery area, work orders placed on to finish the whole grinding process business

China launched "diamond tool industry TuWeiZhan" United States

时间 : 2020-06--22
With China's enterprise more and more deeply into the international economic arena, international economic frictions and disputes of also increases. Although American federation of diamond saw blade production enterprises to American government, South Korea filed two countries for the diamond sawing the anti-dumping and components, but so far unresolved for Shanghai stone industry associations, and other intermediary institutions in the first time organization since robbed of jiangsu, zhejiang, Shanghai dozens of Chinese enterprises, three to deal with the us antidumping pressure, and mechanical and electronic import and export Chambers of commerce in China, Chinese stone material industrial association and other related organizations, in the full study based on U.S. indictment, find out the case the breach. At present, China industry already hired sino-us legal and accounting, and actively responding anti-dumping experts try to win of the Chinese government and the support of U.S. partners. At present already off to a spearhead of commerce. American diamond saw blade production enterprise confederation prepare eight months, raising $1.2 million on May 3, submitted to the American government in China, South Korea and components in diamond sawing the anti-dumping application. As of May 31, China is already the U.S. prosecution from the original enterprise May 3rd 23 home when up to 53 home, including jiangsu, zhejiang, Shanghai enterprise 60%, with illegal money $26 million. China diamond saw blade production enterprise is the cause of their American counterparts prosecution: American firms think that low-cost imports from China already cause of diamond circular saw blades on American domestic industry substantial damage. The United States quoted the customs statistics sources, said the two countries, South Korea's exports to the United States diamond circular saw blades from 2002 870 million increase to the 2004 46,657 million, causing the United States to enterprise fails to enjoy the benefits of construction industry boom, instead of U.S. companies can compress the profit space, cause home 1 enterprise bankruptcy, many enterprises market share narrowed, their American counterparts caught by "steel and energy costs and product prices falling embarrassing position". On May 3, 2005, the international trade commission received U.S. producers in the so-called "in China, because the United States anti-dumping" apply to the United States international trade commission diamond sawblade manufacturers association ShenSuZhuang "whether to have submitted the necessary industry support" doubt, hence decided to extend questionnaire single, collecting relevant industrial support information, embark on "damage" investigation, questionnaire recovery on May 25, already submitted by complete. A source says the us international trade committee is expected to "damage" held recently about the first hearing problems on June 17 will make preliminary ruling. Diamond circular saw blades has become China's export international tool market's flagship product, domestic numerous enterprises and some listed company ambitious, the production line in preparation in the two years to put into production, the United States if the implementation of the "anti-dumping", for the enterprise is undoubtedly preoccupied. According to the Shanghai stone industry association secretary-general dr FanLinGen introduced, the global diamond saw blade production since 2000 mass shift to Asia, China enterprise production of products mainly facing ZhongDiDuan market. According to us statistics, from 2003 to 2004, China lost 20 diamond circular saw blades quantity annulus beautiful increase in more than 30%. To this, the United States the prosecution presented litigation material seems very is confidently, says our products are exported to USA price far below the normal cost, dumping of 298.39%, namely the United States customs for Chinese products if 39% of how levy 298. Tariff, just not for dumping. China's involved or not, and if not responding enterprise involved in the future, the product exports to the United States by anti-dumping case ruling the highest tax rate after taxes. For American counterparts wishful "count your chickens before they hatch," dr FanLinGen refute, China products shall be determined according to the cost of computing is factors of production, such as working hours, raw material consumption, energy consumption, etc TiDaiGuo (this case selection multiplied by the unit price reflects Indian) real production cost, plus fixed convert the management expenses, profit, etc. As a developing country, China's artificially and material cost advantages are obvious, simply does not exist in the so-called "dumping the myth of 298.39%".       At present, the diamond saw blades are become China's emerging export growth point, normally, investment of diamond materials and set of high-grade production equipment need to millions of yuan blades of f

Alloy blades were industry

时间 : 2020-06--22
A, alloy circular saw blades when many factors in the grinding to be ignored      1. The matrix deformation big, thickness not consistent, inner pore tolerance is big, the matrix congenital defect problems, no matter use that type of equipment, there are grinding error. Matrix deformation of two side Angle large produces deviation, substrate inner hole diameter jump to produces deviation; After inconsistent base thickness of blade Angle and anterior horn are produces deviation, if there are cumulative work too poor quality and precision blades have been affected.      2. Gear grinding machine structure on the grinding of gears influence, alloy circular saw blades gear grinding machine structure and assembly quality lies in the market now about class type: one kind is Germany's vision, which float type by vertical grinding machine, the advantages all adopt hydraulic steplessly movement, all feeding system adopts V type guideway and ball screw work, grinding head or big arm with the feed slow retreat quickly into, recede cutter, clip piece oil cylinder regulation center, a piece flexible reliable, dial the tooth accurate positioning, blades set position center firm automatic aleatoric Angle adjustment, center, reasonable, realize the cooling flush with human-machine interface, grinding accuracy, high pure grinder reasonable design; Second, such as Taiwan is currently horizontal machine, mechanical transmission Japanese existing gear and mechanical clearance coattails "sliding precision is poor, clip piece smoothly, a poor performance piece center adjusting difficulty big, pull teeth institutions or poor reliability, plane after both sides and angles are not in a center around grinding, produce big deviation, Angle difficult to control, abrasion distress ensure accuracy.      3. When soldering alloy welding factors, for moderate deviation is big, influence, grinding accuracy caused side grinding head pressure big, side after pressure small, also produce the above factors, corner soldering Angle is poor, artificial inevitable factors of grinding wheel, such as when the factors arise unavoidable influence.        4. Grinding wheel quality and granularity width influence, choose one hour, pay attention to grinding wheel break-in gold particle, particle size too thick grinding wheel grinding wheel trace, produced chosen fine granularity easily blocked grinding quantity is little, easy to burn knife. Grinding wheel diameter and thickness is according to the width of length of size or not alloy tooth shape and alloy each face up, not a corner after corner like norms or before grinding can be, can be arbitrary grinding different serrate type, must have targeted to choose suitable for specifications grinding wheel.      5. Grinding head into to speed grinding, alloy blades or fully determined in grinding head into relevant to speed, the general alloy circular saw blades into to speed 6 mm/SEC cannot speeding this value, namely every minute should be in 20 teeth every minute, within 20 teeth at the feeding speed is too big, can have serious sarcoma or burn alloy wheel sword produced affect concavo-convex surface grinding gears precision, waste the wheel.        6. Grinding head feeding, choose grinding wheel granularity is extremely important to feed amount significance, general grinding wheel the proposal chooses 180 # to 240 # extremely quantity choose 240 # to 280 #, do not grant to choose 280 # to 320 #, or to adjust the feeding speed.      7. Grinding center, all saw blades for the center with grinding the matrix, not a knife as the center, plane grinding center after take not to come out, the anterior horn horns, with processing center cannot grind a saw blades, grinding three process should not be neglected in blade center. Grinding side Angle was still careful observation of alloy thickness, thickness different grinding center change, no matter how thickness, grinding alloy wheel with flanking centerline should keep welding bits in a straight line, or produce Angle cutting greatly affected.      8. Dial the tooth institutions can not be ignored any gear grinding machine no matter how and, dial the tooth structure design involves coordinate accuracy grinder, made in adjustable unit dial quality of gear tooth surface pressure in the needle, not reasonable position of mobile is also and key and withdrew tooth, dial the tooth claw to be flexible and reliable.        9. Clip piece structure: clip piece structure fatigue solid stable and reliable, and the main parts is sharpening quality, any sharpening your piece structure not any loose, no side grinding of gears deviation serious abuse.        10. Grinding trip, regardless of any part of the grinding sawblade grinding head grinding trip is very important, general requirements than 1 mm grinding work or quit 1 millimeter advisable, or to other tooth influence.        11. Program choices: sharpening general equipment is rough and fine, grinding three
