High-speed CNC machining centres put different demands on way-protection than conventional machines. The continuous wave (sinus) profile of a Sinus Armour Joint is designed specifically around those demands.

Lower friction, smoother travel

Because the sinus profile flexes continuously rather than pivoting at discrete hinge points, it moves with less resistance, which can help maintain smoother axis travel at higher speeds.

Reduced operating noise

Fewer moving joints means less mechanical noise during rapid traverse.

Long fatigue life

Manufactured from spring or galvanized steel selected for repeated flexing, sinus covers are built to hold their shape over extended duty cycles.

For machines running long shifts at higher speeds, this profile is worth considering over a traditional hinged cover.
