DEAD-LENGHT COLLET SYSTEM UNILOCK COLLET-CHUCK FOR C.N.C. LATHES clomping solutions THE ACCURACY OF MECHANICS, THE HUMAN TOUCH.

SMS - COLLET-CHUCK DEAD-LENGTH COLLET SYSTEM With this system the collet remains stationary coupled to the spindle clamping nut while the rear tapered cylinder advances for tightening. The collet is changed quickly by simply loosening the front clamping nut. The collet closes parallel to the bar without interfering on its position. Main uses Applied to the lathe counter-spindle, tighten the piece without loading the spindle axis and do not trigger the alarm of the C.N.C. Suitable for bar and secondary machining, with excellent tightening repeatability. Available in following models: SMS 45 -...

SMS - CLAMPING COLLETSDEAD-LENGTH COLLET SYSTEM SMS clamping collets are made up from metal inserts, units of vulcanised rubber. This allows the collet to close radially in a perfect manner, blocking the piece along the entire length of the hole and eliminates the intrusion of shavings to pass inside the spindle. Applied to the lathe main spindle it is suitable for bar machining. Moreover, the construction flexibility of the system allows easy specific solutions (drawn bars, rectified items, rolled items, pipes). All the UNILOCK SMS COLLETTS are COMPATIBLE with FB, BA and DIN 6343. UNILOCK SMS...

High friction coefficient SUPER GRIP The "dynamic friction coefficient" is determined on the basis of the roughness present inside the collet and must be considered according to the type of material to be machined (e.g. stainless steel, steel, brass).

COLLET-CHUCK DEAD-LENGTH COLLET SYSTEM TECHNICAL FEATURES SECONDARY MACHINING A seat for a retainer with adjustable tip to use in secondary machining has been realised inside the collet sleeve. Adjustable retainer QUICK CHANGE CLAMPING NUT Just loosen the clamping nut to remove it and change the collet. Quick change clamping nut BAR MACHINING A seat for a bar orientation bush has been realised inside the collet sleeve. Via the automatic loader, the bush allows the orientation with the closing collet, in the loading phase. Ideal for hexagonal, square or profile bars. Bar orientation bush www.unilock.it...

SMS - CLAMPING COLLETS DEAD-LENGTH COLLET SYSTEM TECHNICAL FEATURES TAPERED COUPLING CLOSURE This feature allows each individual sector if the collet to close radially, thus clamping the piece along the entire length of the hole and developing a clamping force from 5 to 10 times greater with respect to “traditional mono-cone” collets, which only close on the front edge. They replace the double cone collets. The strong clamping force of the Unilock collet greatly reduces vibrations and resonances. BAR CLAMPING WITH STATIONARY COLLET The Unilock collet closes parallel to the bar axis without interfering...
