KM4X63 Speed Capability KM4X™ uses more interference between the male and female taper leading to: • Higher rigidity – Better distribution of clamping force between face and taper. – More rigid connection that allows for higher bending and torsion loads. • Higher spindle rotating speed – As RPM increases, the spindle taper expands at a faster rate than the tool taper. – Higher interference allows for a higher RPM before the two tapers lose contact. KM4X63 Features The KM4X system’s superior rigidity and accuracy is gained by optimized interference ISO standardized V-flange (HSK) levels. Three-surface contact areas develop when and features for automatic clamped, resulting in superior performance. tool-change arms. Four locking elements for power, drive, and uniform rigid locking. HSK-A form protection Provides even distribution of forces. zone (Rotating). HSK-T form protection zone (Static). Two keyways used for location, secondary drive, and orientation.
