KM Quick Change KM Mechanical Advantage WIDIA The KM Mechanical Advantage A comparatively increased mechanical advantage is one of the central reasons In the following sections, you’ll find expanded information about the KM Quick Change why the KM Quick Change Tooling system is superior to other tooling methods. Tooling system’s mechanical advantage and how enhanced levels of these forces The high mechanical advantage is achieved through the system’s rigid interference make WIDIA tooling superior to other quick-change systems. fit that is generated by additional forces in the clamping mechanism. A clamping device with greater than ordinary mechanical advantage offers many benefits in regard to tool life, downtime, and overall machine cost. Front-Loading Spindle Design The KM Advantage KM spindle designs are front loading; this enables easy access to the KM spindle if repairs are necessary. The Competitor Disadvantage Most other spindle systems are not a front-load design, and when repairs are necessary, the entire spindle must be removed. This causes the machine to be down for an extended period of time. Mechanical Advantage in Clamping Force The KM Advantage The KM design is an interference fit that enables the KM system to generate 4:1 and upwards of 7:1 mechanical advantage in clamping force. The Competitor Disadvantage CV, BT, HSK, and PSC mechanisms requires a high degree of pull-back force to generate clamping force. The design generates a high amount of pent-up force within the spindle. When a crash occurs, the forces are released and could possibly damage the entire spindle mechanism. Mechanical Advantage Provides: Lower tool release forces. Smaller clamping mechanism envelope Resultant Clamping Force 5,000 LBF 22 kN
