EPB 5672 High precision collet chucks EPB 5672 External presentation EPB 5672 High precision collet chucks Longer tool life time, better surface finish due to a max. 3µm at 3xD run-out, Higher transmittable torque and rigidity: higher productivity and process security, Suitable for HSM (High speed machining), Wide range offering optimised solutions, whether you privilege accessibility, rigidity or the best compromise between both, Easy assembling of a large range of collets, including sealed collets. © 2018-09-21, all rights reserved

Product description Global overview Maximum run-out with a new generation type 5672 collet is 3μm measured at 3xd gauge length in relation to the external shank taper Top of the collet at the same level as the top of the nut: no loss of rigidity 3 projections: short, medium and long, allowing optimized solutions to every needs   Coolant delivery through the tool, using sealed collets Strong design (OD chuck body = OD nut) providing an optimized compromise between high rigidity and work-piece accessibility   Axi-symmetrical design = perfect balancing Fine balanced at 3g.mm/kg (3g.mm for holders under 1kg; for holders <=HSK50: 1g.mm/kg, but 1g.mm when holder <1kg) Designed for HSM Wide offerof machine side connections (HSK-A, HSK-E, DIN, BT, CAT, Graflex, Seco-Capto) © 2018-09-21, all rights reserved

Product description Collet chucks body High flexibility regarding the positioning of the tool shank in the collet → possibility to reduce the overhang of the tool in order to increase the rigidity of the assembly. Collet fully seated in the pocket = perfect clamping of the tool, all along its shank. The chucks internal central bore allows to insert the tool deeply in the holder=high flexibility regarding the depth positioning of the tool EPB 5672 Other collet chucks © 2018-09-21, all rights reserved

Product description Conventional collets Blue ring = identification of high precision ER HP collets Overall high precision ground Reduced number of slots (12 vs. conventional 16 slots) thanks to specific steel and heat treatment specific steel and heat treatment) => reduced deformation of the collet Nominal clamping only, for an optimal contact surface between the tool and the collet’s bore, providing perfect positioning of the tool, concentricity and stability Polished for a better clamping Direct, manual fitting of the collet into the nut (no need for additional equipment) Collets design = “damping” effect © 2018-09-21, all rights reserved

Product description Sealed collets Same features as the ‘non-sealed collets’ Seals to plug the splits © 2018-09-21, all rights reserved

Product description Locking nut Two cylindrical guides for a perfectly concentric clamping of the nut on the chuck With trapezoïdal thread and extra-long guiding pads= perfect centring of the clamping nut on the chuck Perfectly Axi-symmetrical design (no asymmetrical clic-fit) © 2018-09-21, all rights reserved

Advantages and benefits (1/2) Longer tool life, better surface finish Run-out max. 3µm at 3xD, Reduced tooling cost and tool changing time, making it a great a solutions for large series, Better surface finish and tight tolerances machining possible, limiting the need for finish operations. Suitable for ‘fragile’ modern cutting tools (CBN, PCD…)   High productivity, as a result of: Higher transmittable torque and rigidity (tool clamping force up to more than double vs. existing collet chucks), Designed for HSM: Axi-symmetrical by design and fine-balancing guaranties a perfect balancing. Reduced spindle load Vibration damping effect resulting from the ‘collet’ design. © 2018-09-21, all rights reserved

Advantages and benefits (2/2) Universal chuck offering very high flexibility Suitable for all kind of machining operations (drilling, reaeming, milling…), Allows to clamp several tool shank diameters on the same holder, using a combinaison of nuts, Perfect combination between rigidity and accessibility to the workpiece, Suitable for all possible methods of supplying cooling lubricant (AD, B, air cooling…). Perfectly safe production process High quality design and manufacturing of the collet chucks, collets and nuts provides: Extremely high clamping forces=no risk of tool sliding out of the toolholder, Reliable and performant positioning of the tool (axially and radially), Accurate repeatability. Dynamometric spanner guarantying the transmittable torque.   User friendly, long lifetime Easy assembling of a large range of collets, for tool shanks Ø 1 to 20 mm (1/8" to 3/4"): low setting time and accurate repeatability Dynamometric spanner preventing damages to the collet chucks. Chrome coating ensuring protection against corrosion. © 2018-09-21, all rights reserved
