Modular Adaptation System A clamping screw pushes the shank of the tool through a narrowed opening, forcing elastic deformation of the steel holder. As the steel contracts around the tool, contact is made around slightly more than a full 180°. The result is rigidity comparable to a solid part. Modular Adaptation System CLICKFIT Clamping Enhances the Tool's Performance Material: Alloy Steel Weldon Clamping CLICKFIT Clamping Depth of Cut = 40 mm Larger Depth of Cut Smooth Operation!

INTRODUCTION Balancing Definitions Balancing Elements Introduction Balancing is the process of equalizing the mass distribution of a body so it rotates in its bearing without unbalanced centrifugal forces. Balancing causes reduced vibration, lower spindle strain, improved machining qualities and allows for higher cutting parameters. The measuring equipment available today enables unbalance to be reduced to low limits. However, it would be uneconomical to exaggerate the quality requirements. It has therefore become necessary to determine to what extent the unbalance should be reduced and...

INTRODUCTION Balanceable Collet Chucks Balancing Elements Example 1 U=2 g x mm can be treated as an unbalance mass of m=2 g in radial distance of r=1 mm or as a mass of m=0.1 g in radial distance of r=20 mm, etc. Example 2 The residual unbalance is independent of the speed. This value reflects the unbalance mass and its distance from the true center of mass. The residual unbalance value is measured on balancing machines. U 4 U = m x r = >m = = = 0.2g r 20 G value reflects the balancing quality of a toolholder according to its rotational speed (N) πx N U Ux Nx π G = Ω x e = 30 x M = M x 30 G...

INTRODUCTION Balanceable Collet Chucks e in g x mm/kg or eccentricity in µm Balancing Elements N in RPM Short Formula U= M . 9,545.G N U = Residual unbalance (gr x mm) M = Tool mass (kg) G = Balance grade N = RPM Please note: The values on the balancing rings are indicated in metric values. Therefore all guidance examples for balancing are in the metric system. ISCAR can commit only on unbalance values larger than 1grxmm A8 ISCAR • ETM Value examples M = 1 kg G = G2.5 N = 15,000 RPM U= 1kg . 9,545.2.5 15,000 =1.59 gr x mm

INTRODUCTION Balanceable Collet Chucks BALANCIN Collet Chuck & Top Nut Operating Instructions The following procedure should be adjusted according to the specific type of balancing machine being used. 1. Loosen the 3 locking screws on the angle reference ring (blue). Align the two balancing rings (gold-colored) to the ‘0’ position on the angle reference ring. After the rings are all aligned, tighten the 3 locking screws. 2. Insert the collet chuck into the spindle and tighten it using the pull stud. Insert the cutting tool into the collet chuck, adjust to desired projection and clamp it. 3....

INTRODUCTION Power Chucks With this tool, only a small tightening torque compresses the frontal nose, providing an extremely high gripping force. It is designed for roughing and finishing applications in milling where high torque transmission, maximum accuracy, compactness and easy operation are required. Features • The clamping nut is not threaded (as in ER collet chucks) • Designed for direct chucking of the tool shank – no need for intermediate collet for maximum gripping force • Sealed nut construction • No axial drawback of the tool shank • as chuck is tightened • Thick wall...
