Experimental study of the effect on the structural characteristics of the tool shank chuck

The article considers the influence of the parameters of the tool on the characteristics of the tool сhuck, depending on the clamp pressure and friction. The objective of this research is to study the effect of diameter deviations and shank stiffness on characteristics of high-speed tool chuck with tapered elastic sleeve clamping system. It was found that the problem was not resolved completely and are not considered at all for some cases. The experiments to determine the pushing force and scrolling torque for shanks with nominal diameters and deviated. The chuck gain factor for both cases are calculated. The effect of gap between the clamping element and the tool shank for shank various diameters at various clamping pressures on scrolling torque and pushing force are described.
