Summary

The guideway is utilized to make sure moving of the cutting tool or machine tool operative element along determined path. Slide-ways and anti friction slideways are two sorts of guideways. Slideway is mainly designed for wear resistance and stiffness. The pressure acting upon mating surfaces create wear. Therefore it is necessary to resist wear. The design for stiffness specifies that the deflection of cutting edge because of contact deformation of slideways should not exceed permissible value, which is needed to maintain the accuracy. Spindle is usually used for centering and clamping the workpiece, and imparting rotary motion. Spindle is mainly designed for bending stiffness.
