Lathe numerical control lathe and hard line rail rail

believe that it is often heard a hardened rail and rail line nc lathe, the choose and buy will involuntarily asked: how hard track is still line rail good? What is the difference between the two? Hard rails CNC lathe refers to the guide rail and the lathe bed is the integration of casting parts, and then on the basis of casting processing guide. Cast out the shape of the guide rail, the bed body again after quenching, grinding processing into the guide rail, also have a lathe bed and guide rail is not must have a body, for example with guide rail, steel is processed the nail on the bed. CNC lathe generally refers to the rolling guide rail line rail, machine profession is now frequently used linear module used in the sort of, let's call this kind of element for linear guide '. Linear guide is divided into two parts: the slide rail and sliding block. Slider inside the inner loop of ball or roller, the length of the slide rail can be customized, is a kind of modular components, there are specialized manufacturer to produce standardized series of products, alone can device on the machine tool, can tear open come down to replace after wear and tear. A lot of finishing in the field of machine tools, most of them are with high precision line rail as a machine tool guideway, it also ensure the machining accuracy of machine tools. About two kinds of nc lathe of said no good and bad, can only say that right is not appropriate, because of the different emphasis. 1. Numerical control lathe hard hard rail rail sliding contact area is larger, good rigidity, seismic ability strong, strong bearing ability, suitable heavy load cutting. Belong to dry hard rail conflict, due to the contact area is large, the friction resistance is bigger also, movement speed cannot too fast. Is used for creep phenomenon, with mobile appearance exists gap will cause processing error. Machine tool trajectory is the key of the maintenance, once smooth trajectory is not abundant, it could cause burned or wear track transition, these are killed for the precision of the machine tool damage. Hard track of CNC lathe using appropriate heavy cutting, large mold, high hardness of the workpiece, the general accuracy of workpiece. 2. Line rail now a lot of numerical control lathe machine running speed, especially in idle speed, the is largely dependent on line rail merits and accomplishments; Rail line through preloaded processing can reach zero gap between trajectory, high precision; In terms of using full, hard line rail and much higher than the rail. Related to the cutting force under the hard line rail track are smaller, only for hard rails, its end line rail in many machine tools have greatly boosted its load-bearing ability. Line rail in CNC lathe using appropriate high-speed machine, can high speed cutting, appropriate, small precision mold processing products. Now more and more fine machining center using CNC lathe is the line rail.
