COMPENSATING CHUCKS OVEKA & KA Information on guarantees: SwissChuck.com/warranty

COMPENSATING CHUCKS For centric cylindrical, orbital pin or form grinding of complex shaft-type components, the workpiece is generally ground between centers. The challenge faced by the workholding device is to transfer the necessary torque, and thus the rotational movement to the workpiece, without deforming it by excessive lateral loads. SwissChuck’s high-precision OVEKA/KA compensating chucks have been originally designed for the machining of crankshafts, a task for which they have amply proven themselves. Over the years, these chucks have undergone continuous improvements such that today,...

EXAMPLES OF APPLICATIONS 2OVEKA 140 Gear shaft: Clamping between centers of a gear shaft – Grinding the outer diameters – Typical application of grinding between centers – High roundness and concentricity accuracy 3KA 140 Ball screw shaft: Clamping of ball screw shafts between centers – Grinding of the ball screw track – Accurate and firm positioning of shaft to the center point – Very short and thin-walled clamping location 2OVEKA 140 Camshaft: Clamping camshafts in the pitch circle of the gear profile – Form grinding of the cam geometry – Angular pre-alignment with special positioning mechanism...

2KA 170 Capto tool holders: Clamping of different Capto tool holders – Grinding polygon and face – Stable and powerful clamping – High flexibility based on multiple adjustable jaw concept – Minimum of interchangeable parts – Only 2 sets of clamping jaws for the clamping range of ø 10 to 80 mm – Short changeover times – Clamping on tapered diameters with compensation of angular differences 4OVEKA 206 Crankshaft: Clamping of crankshafts between centers – Grinding of crankpins and main bearing journals – Generally suitable for automotive crankshafts (up to 6 cylinders) – Meets highest requirements...

TOP JAWS The top jaws are designed workpiece specific by SwissChuck. In this way, the clamping function of the chuck will be perfectly transferred to the workpiece. The generally hardened jaws can be given an additional PVD coating at the clamping contact locations. This permits an even higher transmission of torque, or alternatively, the clamping force for sensitive workpieces can be reduced. CENTER POINTS As a rule, the wear-resistant center points are fitted with tungsten carbide inserts. The conical or spherical centers are designed and produced according to requirements. Some chucks are...
