Limited company of development of business of Shanghai female peaceful is a large investment accuses model group company, register fund 60 million yuan of RMBs. It is collect equipment of nonferrous metal and mine product, Electromechanical and its spare parts and the foreign trade of all commodity, rare precious metal, mineral products resource is developed, nonferrous metal smelt, the business such as integrated commerce is the diversity group company of an organic whole. Company of female peaceful of the Shanghai at the beginning of 2004 grows limited company to begin to sell guide screw of ball of Ke Er spy in Chinese area, female peaceful company became area of China of product of guide screw of ball of group of Ke Er spy formally to always act as agent in April 2005. The company of big, heavy-duty machine tool that so far already more than 20 have larger force in industry of Chinese machine tool becomes the faithful user of guide screw of Ke Er spy. Spanish Er stalking or branch is special the company already had 30 perennial to produce the history, it is at present Spain produces ball guide screw to specialization largely company, take the first place that market of machine tool guide screw sells in Spanish home at present, one of the mainest suppliers that have international major level also are on the international market. The respect such as the design of company of Ke Er spy in guide screw, production and market has very rich experience. Have international to can carry sacrificial vessel to domestic and international client the product of advanced level, they try hard ceaselessly, test and verify its product has achieved international on quality top level. No matter product of company of Ke Er spy is in the price, there is absolutely advantage on quality and date of delivery. At present the sale network of company of Ke Er spy pervades 5 continent of world make multilateral home: Spain, france, italy, korea, japan, australia, south Africa, india, the United States, finnish, argentine, china. Exit product occupies the 70% above of company total sales. Guide screw of ball of Ke Er spy is having distinctive market product to locate, its product includes guide screw of high accuracy ball, big norms not to have guide screw of ball of carry on one's shoulder of guide screw of butt joint ball, burden and nut to come back transition ball guide screw. Guide screw of high accuracy ball: The diameter that normally we offer for domestic leader business is in the guide screw of 63-125mm, its sheet root can achieve 13m without butt joint length, precision is between IT3-IT5. One is in in production domain of ball guide screw cannot evasive difficult problem is as guide screw length increase, corresponding guide screw precision can drop. For example, in cover with tiles with Dalian at first in the arrange with process of limited company of machine tool of Ding Xishi of machine a place of strategic importance, they also showed this kind of concern, with the machine tool because of production exit the precision to guide screw of big norms ball asks very tall. Examine except the requirement the journey error of groovy Lead/300, the error to every lead also can raise corresponding requirement. The tall disappear of the precision of guide screw of ball of Ke Er spy the trouble back at home besides the user, in the use requirement of the machine tool. No matter the guide screw of ball of big norms high accuracy that company diameter is 63-100mm series is quality or price have very strong competition ability. Guide screw of big norms ball: The odd root of 11m of the diametical 100mm that factory of heavy-duty machine tool uses Qinghai China vessel, length does not have guide screw of butt joint ball, be a model need not the guide screw of ball of train in excess specified length of the butt joint, no matter be,ask in precision and the Dou Yuangao on product life receives guide screw at be opposite. Weigh load ball guide screw: Guide screw of heavy load ball expands as the development of domestic leader business, level of design research and development also rises ceaselessly, in ball guide screw choose on gradually incline to high accuracy, heavy load, train in excess specified length is spent and big lead. Guide screw of ball of Ke Er spy complied with the Spain that has experience of guide screw of 30 old production ball just about the demand of home market, provide the product with excellent quality and good service for domestic leader business, continue to hold lead dominant position in domain of big norms guide screw. The diametical 160mm that in Wuhan milling machine of boring of shift of door of double dragon of numerical control of factory of heavy-duty machine tool offers, length 7.
The guide screw that 7m, precision is IT5 class is the product of ball guide screw of the biggest specification that provides for domestic user up to now, its dead load amounts to 250t, move load to amount to 52t. Guide screw of ball of nut transition coming back: As the advance rapidly of modern production technology, emerge as the times require of a batch of another batch machine tool of high speed numerical control. Its ask to function tells main shaft outstandingly not only, and also put forward to feed system very tall. Guide screw of high speed ball deputy it is to point to can get used to high speed to change requirement, contented bear the weight of requirement and the ball guide screw of can exact location deputy, it is the first selection drive that high speed of machine tool of implementation numerical control changes and fixed position component. The ball guide screw in numerical control machine tool often is in predicting load big, rotate speed is high and medicinal powder the job below the condition of hot difference, because this guide screw is easier calorific. The consequence that ball guide screw heats up production to cause is very serious, it is especially in open loop system, this meeting makes feed system loses fixed position precision. Traditional ball guide screw drives nut and workpiece movement by the guide screw of drive of servo electric machinery. To get used to market demand, company of Ke Er spy developed nut to come back transition ball guide screw and hollow model ball guide screw. Guide screw of ball of nut transition coming back is servo electric machinery drives nut to rotate directly, drive workpiece is mobile, reducing calorific, reduce moment of inertia and the performance with reduce the respect Dou Youliang such as noise good. Heightening effect of feed career side especially very remarkable. When engineering personnel is being designed, classics regular meeting encounters such situation: The working distance that asks as a result of machine tool place is greater, be in normally 7m above, considering the self-prossessed problem of itself of common ball guide screw, guide screw moment of inertia is too big, because this must take the kind of gear rack drive. And as it happens of guide screw of ball of transition of nut of Ke Er spy coming back can overcome guide screw self-prossessed the flagging problem that pose, take the reasonable kind that prop up, guide screw of ball of theoretic nut transition coming back can grow indefinitely, be restricted to exceed equipment offerred perfect transmission solution.
