These power drawbars provide high static and dynamic stiffness generated by the high retention force and face contact of the tooling. Higher spindle speeds with greater axial and radial repeatability of hollow shaft tooling is achieved due to the face contact and clamping forces. Drawbar package includes gripper unit, drawbar, clamping cartridge, three position sensing signal ring, rotary union and machining of drawbar contour in spindle shaft. | | | | | | | | | | | | | | | | | | | | | | | | | Rear Bearing* | | Type '2KL' | Type '2KA' | | | | | Size | RPM (max) | Retention Force (N) | U-1 | L | U-1 | L | C (min) | | | | HSK 40A | 55 | 10,000 | 6,800 | 55 | 101 | 60 | 115.5 | 270 | | | | HSK 50A | 55 | 10,000 | 11,000 | 55 | 101 | 60 | 115.5 | 280 | | | | HSK 63A | 55 | 10,000 | 18,000 | 55 | 101 | 60 | 115.5 | 340 | | | | HSK 80A | 65 | 10,000 | 28,000 | 55 | 101 | 60 | 115.5 | 380 | | | | HSK 100A | 65 | 10,000 | 45,000 | 55 | 101 | 60 | 115.5 | 535 | | | | | | | | | | | | | | | | | | | | | | | | *Minimum rear bearing bore size (mm) | | | | | | | | | | | | | | | | | | | | | | | | | Rear Bearing* | | Type '2KL' | Type '2KA' | | | | | Size | RPM (max) | Retention Force (N) | U-1 | L | U-1 | L | C (min) | | | | HSK 50B | 55 | 10,000 | 6,800 | 55 | 101 | 60 | 115.5 | 270 | | | | HSK 63B | 55 | 10,000 | 11,000 | 55 | 101 | 60 | 115.5 | 280 | | | | HSK 80B | 55 | 10,000 | 18,000 | 55 | 101 | 60 | 115.5 | 340 | | | | HSK 100B | 65 | 10,000 | 28,000 | 55 | 101 | 60 | 115.5 | 380 | | | | HSK 125B | 65 | 10,000 | 45,000 | 55 | 101 | 60 | 115.5 | 535 | | | | | | | | | | | | | | | | | | | | | | | | I_-----"—_I___I__ *Minimum rear bearing bore size (mm) | | | | | | | | | | Rotating Cylinder Power Drawbars — are available upon request.
