NEW BABY CHUCK are capable of achieving high spindle speeds as required fordrilling and end milling with smaller diameter cutting tools. Collets of the highestprecision achieve close to sub-micron concentricity, compatible closing nuts andover 250 versions of the chuck bodies are available in the standard range. TheNEW BABY CHUCK is the most reliable solution for high precision machining.COLLETCollets for New Baby Chuck arespecially processed to achieve a superhigh precision never before possible.Runout of collet1µ 3µMAX.20,000min -1BT30/BT40/DV40COOLANTTHROUGH HOLENUTA 45° trapezoidal screw thread offers less friction when clamping colletand provides better balance with automatic centering force of collet nut.High accuracy of collet nut thread is produced by unique precisionfinishing process after heat treatment. Accordingly, this minimizesvariations in accuracy and allows for more powerful gripping force.All collet nuts incorporate Ball Thrust Bearings which prevent stress tothe collet, thus allowing a smooth gripping force to the collet.Original internal construction retains steel balls at high centrifugal force.45°45° trapezoidalscrew threadEach collet is inspected anddouble checked to meet maximumrunout tolerance permitted, i.e.,100% check & re-check.4dMax.

Therefore, this system is ideally suitablefor machining centers; turning, grinding, milling anddrilling machines; and variety of other applications.COLLET6 different collet series ......6, 8, 10, 13, 16and 20 covers any size diameter between0.25 and 20.SYSTEMBODYThese include integral tapered and straight styles in short, long and extra long length to meet allproduction and workshop requirements.For HSK shank style, please refer to Catalog No.181.COLLETDouble rib design (PAT.) assuresfast and easy insertion andremoval of collet.Push gently at designatedmark for removal of collet.After mounting, collet will remainsecurely within nut and will not fallout and be lost. Damage due topoor or loose mounting iseliminated.COOLANTCollet will not drop out by shakingMax. 70kg/cm 2SYSTEMWith larger angles, the collapsibility range of the collet ( d) willincrease, but gripping force will decrease.With smaller degree of taper, the projection length (A) of colletwould have to be extended to enable the collapsibility range ofcollet to increase. This, however, reduces rigidity andaccuracy.The NEW BABY CHUCK SYSTEM solves these problemsby utilizing a 12fl taper with a minimum collet projection length(A) and a longer collet gripping length (B), thus assuring rigidity,a powerful gripping force, a large collapsibility range and highaccuracy.ClampingLengthB12° taperProjectionLengthAdCollapsibilityCoolant supply through tool tipCollet-through coolant supplySealed Collet Nut design preventscoolant from leaking through colletand directs coolant through the toolto the tool tip.No scattering of coolant suppliedto the cutting spot via coolantgrooves on the collet periphery.SYSTEMSuperior gripping force permits the applications to drilling,milling, tapping and reaming. Therefore, simple toolingprograms are easily adaptable.Standard NBC colletP6P5DRILLEND MILLTAPREAMERCENTER DRILLSynchronized tapping of M12 to M20 is available bylocating the tap square in the Tap Driving Back Stops.

COLLET COLLET SETWOODEN BOXNew Baby Collet "AA" classification guarantees ultra accuracy of 0.001 at the nose.This is achieved through as pecial manufacturing process. As part of the last phase ofmanufacturing, the collets are carefully tested for accuracy. Finally, the collets arethen passed through a high precision lab inspection and only those collets measuringless than 0.003 at 4 times diameter are permitted to be marked "AA", thus assuring thehighest possible quality and accuracy available in a collet.Complete Collet Set includes all diameter collets within each collet series and a wooden box.A1µApplicationsBModel DescriptionNBC 6 - 0.5 AA3µØdReamer, Center drill, Carbide smalldrill, End mill, Internal grinding wheel,High frequency motor tool, Tap,Boring tool and Turning tools.Collet ClassMax.
