I. Functional role
Slideways are the “track” between the guide rail and the moving parts. They convert the rotary (or linear) thrust of the servo motor into precise linear motion of the machine table, spindle box or turret, while withstanding cutting reaction forces, shocks and vibrations. Once the slideway fails, the positioning accuracy and surface quality of the whole machine will drop directly.
II. Common structure family


Linear ball slideway
Steel balls are in point contact with the raceway, low friction and fast response, suitable for high-speed and light-load Swiss-type lathes or vertical machining centers.


Linear roller slideway
Cylindrical rollers are in line contact with the raceway, high rigidity and large load capacity, the first choice for heavy-cutting equipment such as turn-mill centers and gantry five-face machines.


Dovetail slideway
Triangular interlocking surface, extremely strong lateral force resistance, often used in grinders or ultra-precision machining units that require micro-feed.


Hydrostatic/hydraulic slideway
Oil film supports moving parts, almost zero wear, used for mirror grinding or heavy-duty boring machines, but demanding on the oil supply system.
