Technical Manual KM4X™ System Overview 2. KM4X™ System Overview • Rigid configuration through optimum interference and higher clamping force. • Evenly distributed clamping force. • Simple design allows for front-loaded spindle configurations. Technical Manual • Balanced-by-design for high spindle speed capability. • Designed with turning, boring, drilling, and milling in mind. • Capable of performing in a wide range of operations from low speed to high torque or high speed to low torque. • Easily adaptable into spindles currently using HSK. — Same ATC gripper design. • Higher mechanical advantage yields greater clamping force without requiring elevated levels of pull back force. • Minimal loss of clamping force after continuous use. • Eliminates concerns of fatiguing and sticking fingers. • Higher maximum speed capabilities — Maintains taper contact at high speeds due to the use of interference. KM4X™ three-surface contact for improved stability and accuracy, optimized clamping force distribution, and interference fit provides higher stiffness. kennametal.com C3 KMT_KM4X_Catalog_C002_C003_EN.indd 3 L V i KMT KM4X C l C002 C003 EN S b 1 20169/1/16 12 442:04 PMPM
