In recent years, it is those who pursue machine tool property to rise, company of each big machine tool is developed in effort compound change, much axis is changed, the product that miniaturization, high speed turns. The columnar roller that IKO company develops linear slideway applies already extensively at high-end type, IKO company was analysed at present the demand of machine tool of the high end on the market, in sharp movement structure design respect provided very good reference. Linear slideway comes out earlier, scroll body used the ball that easier product turns, but go after ceaselessly as mechanical equipment high-powered, the columnar roller that has more excellent performance is linear slideway appeared. IKO company in 20 centuries 80 time begin to begin to develop columnar roller linear slideway, after be being innovated via changing a design for many times, the product of newest generation had had a lot of excellent performance. Tall laden tall tigidity pursues the 1 structure that is columnar roller linear slideway. Report to the superior after accomplishing a task of loop of 4 columnar roller is configured, into X model with slippery course 45 ° are contacted, can bear balancedly the bear of each direction. Graph 1 graph the 2 comparison that are basic and rated dead load. Graph 2 graphs 3 it is columnar roller the tigidity of linear slideway compares linear slideway and ball. Can see photograph of as linear as ball slideway compares his laden ability wants a lot of bigger, in maintain laden ability and rigid and changeless circumstance to fall, linear slideway wants columnar roller linearer than ball slideway is small one dimension. While precision of the heavy cut ability that satisfying a machine tool so, tall cutting asks, columnar roller is linear slideway also makes equipment miniaturization becomes a possibility. Accordingly, not only linear slideway got columnar in domain of heavy-duty machine tool, high accuracy machine tool roller apply extensively, portable Plant industry waits in the electron, linear slideway also had columnar roller position. Graph what 3 pairs of feed dictate is tall along with move function cylinder roller linear slideway basically does not produce differential to slide, be in so be pressed beforehand or the coefficient of friction when load is very small also, move especially when direction is changed good along with use a sex, with the high speed reactivity to tiny feed, realized very tall fixed position precision. Graph 4 it is columnar roller linear slideway and ball chafe when linear slideway bear the comparison that power volume changes, can see, linear slideway is in columnar roller when bear change is very big, the change of attrition force is not big however. Such character, raised what its dictate to numerical control to follow use a sex, be in especially finish machining, if circular arc cutting is machined, inside have more on face grinding treatment reflect outstandingly. Graph 4 efficient change columnar roller linear slideway photograph compares linear slideway and ball, what can restrain the generation when device is adding decelerate inside shorter time is oscillatory. Graph the 5 comparison that are earlier amplitude and exhaustion time pursue. In a few treatment that turn to go after high speed, drive equipment used linear electric machinery, columnar roller is linear slideway was to be absorbed quickly more urgent quicken, urgent the vibration that the force when stopping produces, shortened treatment is periodic, rose to machine efficiency. Graph 5 maintenance-free lubricate is linear slideway a very crucial link in using, with bearing, lubricant stand or fall also affected the service life of slideway directly. Below the circumstance with normally lubricant fat, the client uses 3 ～ in equipment between 6 months, need complements grease, but such meetings cause equipment stop production, reduced manufacturing efficiency namely, raised labour cost again; And if use oil-lubricated, need a design to center oil supply unit and oil path, increased to design cost, also created resources waste at the same time. IKO passes old technique to accumulate, developed the buy inside lubricant component successfully model self-lubricating series is linear slideway, graph the 6 internal compositions that are this kind of product. Adopt this kind of new technology, realized 20 thousand Km to perhaps do not need lubricant maintenance-free effect 5 years. Graph 6 graphs 7 it is relevant test result. It is the characteristic of this series product below: Graph 7 self-lubricating the component contains a large number of lubricating oil, can omit the multifarious work that lubricant managing. Distinguish at the tradition self-lubricating principle, self-lubricating the component lubricates directly scroll body, had not produced great attrition resistance, compare with traditional product, saved power. Graph the 8 traditional products with the buy outside lubricant component are different, its exterior dimension and common need are lubricant the product agrees completely, can replace era to use continuously. In process of scroll systematic circulation, lubricant component furnishs only necessary oily quantity, won't create resources waste, more effective protected an environment. For the better performance that improves a machine tool, IKO company rolled out train in excess specified length 2007 model " freeboard precision freeboard is rigid " slide block MX (D) L (graph 8) seal sexual slide block with high density (graph 9) , the client requirement to precision was satisfied on higher administrative levels, increased the dustproof capacity that linear slideway leaves in abominable use condition.
