I believe we all know the difference between wired rail and hard rail CNC lathe, what is the difference between the two?
Linear rail CNC lathe usually refers to the rolling guide rail, is now the machine tool industry often used in the linear module used in the kind; Hard rail CNC lathes refer to the cast parts where the guide rail and the bed are integrated, and then the guide rail is processed on the basis of the casting. That is, the shape of the guide rail is cast on the bed body, and then the guide rail is processed by quenching and grinding. The bed and the guide rail are not necessarily integrated, such as the steel insert guide rail, which is nailed to the bed body after processing.
Now many machine tools work fast, especially space speed, this is largely relying on the line rail credit; The line rail can reach the zero gap between the tracks by pretightening treatment, with high precision; In terms of service life, wire rail is much higher than hard rail. Line rail to withstand the cutting force related to the hard rail is smaller, only for the hard rail, its end in many machine tools of the line rail has greatly improved its bearing capacity. The application of line rail CNC lathe is suitable for high-speed machine, high-speed cutting, suitable for processing products, small molds. Now more processing is the use of line rail CNC lathes.
Hard rail sliding touch surface is large, good rigidity, seismic can be strong, bearing can be strong, suitable for heavy load cutting. Hard rail attributed to dry resistance, because the touch surface is large, so that friction resistance is larger, the speed of movement can not be too fast. Together prone to crawling phenomenon, there is a gap in the moving surface will lead to processing errors. Machine tool track is the priority among priorities in maintenance, once the track smooth is not sufficient, it will cause track burn or wear transition, these are fatal injuries to the accuracy of the machine tool. The use of hard rail CNC lathes is suitable for heavy cutting, large molds, high hardness workpiece, workpiece with general accuracy requirements.
