Jirfine VHU-650

VHU-650 uses B/C rotary motion with XYZ travel 660/520/475 mm, B −35° to +110° and C 360°. Its source describes impeller/blisk applications and simultaneous five-axis motion with SINUMERIK ONE. Determine the required tool orientation and full fixture/holder sweep with the exact CAM/postprocessor instead of treating that application list as an accepted process.

The Ø650 mm table lists 300 kg maximum load without the V-400U horizontal/tilted split. Obtain orientation-specific load, centre-of-gravity and moment conditions for the offered rotary build. Do not transfer the other model’s A-axis travel or load rule here. The source describes hollow screw cooling and full closed-loop scales as manufacturer features, not a completed factory audit or guaranteed part result.

The HSK-A63 spindle is listed at 18000 rpm with a 19/28.5 kW motor pair whose duties are not labelled. The 30-tool magazine limits are 8 kg mass, 250 mm length and 75/130 mm full/adjacent-empty diameter. HSK holders and shorter tool-length limits differ from V-400U’s BT40 package. Include wide-tool empty positions in the actual tool plan.

The linear positioning entry is 0.007 mm for all axes, but the B/C positioning row carries an inconsistent unit label; no numerical rotary accuracy is asserted here. Trial the calibrated rotary centre, holder/clamp clearance, actual path and controlled-stop recovery, then inspect after release under agreed conditions. Plan utilities and loading/service access around the 3350 × 4350 × 3400 mm body, with XYZ rapids 36/36/36 m/min distinct from full process time.
