Fixturing for Components of Hybrid & Electric Vehicles

SOLUTIONS TO SUIT YOUR EXACT REQUIREMENTS You define the task; we develop and implement the solution! Special chucks are designed and manufactured to your specific requirements. The design of those chucks is matched to the workpieces and to the individual machine tool construction. Moreover, SwissChuck offers you the benefit of their know-how gained over decades and from using up-to-date technology. SwissChuck aims to minimise your manufacturing processes, your production costs, enhance your performance and increase productivity. This is most effective by involving us right from the start...

Automotive Components Electric drives Rotor shafts Thumbnails of sample workpieces

Electric drives Rotor shafts Rotor shafts for motors of electric cars Workpiece: Clamping Automation: Workpieces must be loaded by means of a gantry loader Performance: Grinding of all OD diameters in one holding operation, complete machining in < 5min Reference: Pitch circle diameter of gear Clamping: Concentric on gear’s pitch circle Compensating in bore Steady-rest on opposite side - No deformation of thin-walled tube section - Clearance of the outside diameter on right side of gear section - Compensation of out-of-roundness of gear section and bore

For E-motor shaft: – Holding on the gear pitch circle – Low distortion holding due to 6 holding bolts – Compensation function between 2 adjacent holding bolts – Steady-rest on opposite side – Grinding of the complete outside contour on right side of gear section – Compensating internal holding in bore – Releasing of OD holding when retracting the chuck by 35 mm – Grinding of end section on left side of gear section Electric drives Rotor shafts

For CVT gear component: Compensating holding between centers when the chuck is extended, face driven when the chuck is retracted – Complete machining, including holding location as chuck is retractable – Secure grinding of previous holding position due to face driver – Highly accurate roundness 3VKH 100 For gear shafts: Concentric holding of shaft Steady-rest for large gears Integration of the chuck into central drive unit – Synchronous grinding of external and internal shaft end positions – Highly accurate roundness – Extremely compact design · Outside diameter of chuck body ø100 mm ·...

SwissChuck Precision Workholding For gears: Concentric holding on the gear pitch circle - Grinding the bore and taper - Holding by means of flexible rack segments ■ Compensation for pitch errors ■ Compensation for helix errors - Pre-centering for manual loading - Highly accurate concentricity Transmissions Hybrid 3VMCHP 240 So Helical gear: Holding on pitch circle with retraction to axial end-stop - Grinding of the bore and the clutch diameter - Fast change-over of holding jaws, radially accessible mounting screws - With radially adjustable pre-centering location pins

Hybrid Transmissions Operations: Synchronous grinding of bores, tapers, gear faces and outside diameters Clamping - Holding on the gear pitch circle - Axial end-stop on face - Integration into hydrostatic central bearing - Automatic part loading - Sufficient clearance for grinding wheels Workpieces: Automotive crankshafts Operations: Synchrone Bearbeitung der beiden Wellenenden Task - Allow vertical loading in holding position - Referencing of the crankshafts between centers (on machine) - Steady-rest support for crankshafts possible on both sides of the - Torque transmission on thrust face...

For camshafts: 2(3) OVK: concentric holding 2(3) OVEKA: compensating holding – or 3-jaw chuck – Grinding of the cam geometry – Concentric holding with additional steady-rests – Compensating holding between centers – High roundness accuracy For Crankshafts: Holding of crankshafts between centers – Grinding of main journals and crank pins – In general, for automotive crankshafts with up to 6 cylinders – Highest requirements for radial and axial run-out accuracies – Low maintenance operation, hence best suited for high-volume production – Chucks with minimal

3ZLHV 200 For fuel injection bodies: Concentric holding with retraction to axial end-stop – Grinding of the bore for the fuel injection needle – Absolut precise positioning on the axial end-stop – Highly accurate run-out Automotive Components Workpieces: Operations: Range of injection nozzle bodies for rough and finish drilling of injection holes on nozzle body’s nose Holding task – Holding on the body’s outside diameter – Axial end-stop on shoulder – Automatic loading with part presence sensing – High repeatability: With multiple reciprocations – using a test shaft with 60 mm distance to...

SwissChuck Precision Workholding 3KCHP160 Fuel injection nozzle body: Holding of nozzle body with axial end-stop against the bore taper - Grinding the nose of the nozzle body - Axial end-stop on tungsten carbide pin - Concentric holding on outside diameter Hydraulic holding system for steering screws Workpieces: Range of steering screws Operation: Grinding of the ball screw thread
