2010 Full-Line Drill Catalog - Desanto

Our 4-point-clamping sets for minimum quantity lubricationMQL or conventional cooling are compatible. They aresuitable for radial manual clamping. Primarily designedfor installation in spindles (short drilling spindles, multiplespindledrilling heads). Most prominent features: manufacture bearing spacing.Two clamping segments displaced by 180° with 2clamping planes each are uniformly moved outwards witha differential threaded spindle, thereby generating thenecessary clamping force.Thanks to their identical fitting contour, the 4-point clampingsets for MQL - especially developped for the applicationwith minimum quantity lubrication (MQL) and with MQLoptimisedtools - offer the following special features andadvantages: a consistent internal diameter ensures a MQL coolantdelivery to the tool without coolant pockets and offersquick operating times.Toolholders➀ We recommend M Amax. for rough machiningand milling operations. For drilling and reamingoperations a lower deviation of M Amax. up to30% is permissible. Please check the torque witha torque wrench.➁ Depending on temperature and lubricatingconditions these values can be up to 15% lower.➂ Due to the screwed connection, M Tmax. canbe lower with adaptors.HSK-CtorqueM A[Nm] ➀Keysize lineardrawing force bending moment[kN] ➁ M B[Nm] ➁ transferabletorsional momentM T[Nm] ➁ ➂32 3 2.5 8.5 72 10540 6 3 12.5 135 18050 14 4 24 330 39063 24 5 32 570 68080 40 6 45 1000 1570100 54 8 60 1620 4200Installation and principleof operationM ASWThe tool is ejected automatically by the ejectorbeing activated by the clamping jawsDirection ofdynamic effectMinimum lubricationdelivery274
