Zero clearance between reference hole by expansion locating pin!! • Durability of ten million cycl es!! * when using VRA Line-up from pin diameter 03mm!!

Zero clearance between reference hole by expansion locating pin!! Durability of ten million cycles!! X; when using VRA When released (workpiece is loaded / unloaded) When expanded (work is located) Enough clearance Zero clearance Unstable locating accuracy (depends on clearance) Stable locating accuracy by zero clearance When released : Easily loaded/unloaded When expanded : Strong holding force by zero clearance

Action description Application sample Model No. Indication External dimensions Cautions Quality improvement Cost reduction Improvement in expansion locating pin allows high accurate processing / cost reduction in alignment equipments Locate with high accuracy by expanding pin Zero clearance Expansion locating pin expands and the clearance between pin and reference hole become zero which leads to locate with high accuracy. Also locking from the inside of the hole leads to zero backlash. When expanded Cost reduction in accuracy-alignment equipments Improvement in locating accuracy leads to...
