US Patent 6352395B1 
Nikken's Revolutionary 3Lock SystemThe 3Lock System uses expanding internal pressure to achieve full contact of the toolholder flange to the face of the spindle, therefore producing unsurpassed cutting performance and cutting tool life. The 3Lock Holder compensates for centrifugal forces produced by the rotation during high-speed machining. Vibration is eliminated, promoting smooth cutting and longer cutting tool life. Expanding Internal Locking SystemThe 3Lock System captures the maximum pulling force generated at the split second of tool clamping. 
Dampening EffectThe dampening effect extends the cutting tool life by 3-5 times. Eliminating vibration helps to achieve excellent machining results in aluminum, steel, and alloy steel. |
3Lock Technical InformationWhen a 3Lock Holder is inserted into a 3Lock Spindle (before clamping), the gap between the spindle flange and the tool flange is 0.2mm for a 40 taper, or 0.5mm for a 50 taper. When the tool is clamped, the taper cone preloaded by the disc springs deforms radially and slides axially to create contact between the spindle face and the tool flange. 
When the tool is clamped, the taper cone preloaded by the disc springs deforms radially and slides axially to create contact between the spindle face and the tool flange. 
3Lock ConstructionThe 3Lock System consists of a main body with an internal taper configuration housed inside a taper cone. The taper cone is shaped to deform to a 7/24 external taper. This taper cone is pre-loaded on the body with the disc springs. The combination of the taper cone and the disc springs create a dampening effect reducing cutting vibration, thus extending cutting tool life. 
High-Speed and Extended LengthThe 3Lock Holder is ideal for high-speed and extended length applications. It is available in a range of styles and may be compatible with your existing machines. |
