Professional CNC machining center: what is the hard track? What is rail?


Hard rail is a casting that guides the rail and the bed are integrated, and then the rail is machined on the premise of the casting. That is to say, the shape of the guide rail casting in the bed, and then according to the quenching, cutting and processing of the guide rail, the bed and guide rail is not necessarily integrated, such as steel guide rail, after processing nailed to the bed.


Application of hard rail machine tools, line rail generally refers to the flip guide, is the current field of machine tools often used in the linear module used in the kind, we usually call this component "linear guide".


1.cnc CNC machining center: the advantages and disadvantages of hard rail and application


Hard rail rolling contact surface is large, good rigidity, vibration resistance, strong load-bearing capacity, suitable for heavy-duty cutting.


Due to the contact surface friction, due to the contact surface is larger, friction resistance is also larger, the movement speed can not be too fast. At the same time prone to crawling phenomenon, moving the surface layer there are gaps will cause processing deviations. The maintenance of the machine tool track is the first priority. Once the track wetting is not enough, it will lead to track burning or damage to the connection, which is a fatal damage to the accuracy of the machine tool.


Suitable for heavy cutting, large molds, high hardness workpieces, and workpieces with general accuracy requirements.


2.cnc digital control machining center: the advantages and disadvantages of the line rail and the use of


Nowadays, many CNC machining plant machine tools run very fast, especially the air travel speed, which largely depends on the contribution of the track; track pre-tensioned to achieve zero clearance between tracks and high precision; as far as service life is concerned, the track is significantly higher than the hard track.


The wire rail bears the cutting force is relatively small compared to the hard rail, just for the hard rail, in fact, the wire rail of many machine tools now has long been greatly enhanced its ability to bear the weight.


Suitable for high-speed machinery, can be high-speed cutting, suitable for processing goods, small precision mold. Today more precision machining centers use the line rail.
