New Size: KM4X63 KM4X™ The KM4X system is the best large, heavy-duty spindle connection for rigidity because it has superb balance between bending and torsion capabilities from the machine tool. Choosing What’s Right HSK 7/24 Taper 7/24 ISO Taper Face Contact • Two surface contact. • Higher axial and radial accuracy. • Less mass — faster quick change and • One surface contact. • Two surface contact. higher speeds. • Relatively low stiffness. • Higher static and • Higher stiffness • Possible runout due dynamic stiffness. than 7/24 tapers. to taper fitment. • Higher axial and • Low axial accuracy. radial accuracy. • Rigid system.
