# Brother R650Xd2

Hardware · `R650Xd2` · verification: source checked

The Brother R650Xd2 is a CNC machining center with a QT (Quick Turn) 0°/180° turntable pallet changer. Its X/Y/Z travels are 650/400/305 mm and its standard spindle speed is 12,000 min-1. The two-face pallet changer allows workpieces on one pallet to be changed while the other pallet is being machined.

## Safety

- Maximum tool length, diameter and weight are limited by spindle speed, configuration and center of gravity; the document figures are for reference only.
- When using the hydraulic rotary joint, Y-axis travel becomes 290 mm.
- Air supply: 0.4–0.6 MPa; recommended value 0.5 MPa; set pressure higher than the recommended value.
- Max loading capacity can be increased to 300 kg per face by changing a parameter; consult separately.
- For the 40-tool magazine, ATC monitoring and stuck-chip detection are not available.

## Study notes

- CNC unit: CNC-D00. Control axes: 7 (X, Y, Z plus four additional axes); simultaneously controlled positioning axes: 5 (X, Y, Z, A, B).
- Tool storage capacity is listed as 14/22/28 tools; a 40-tool magazine is also listed for R650Xd2 and gives Z travel 435 mm.
- QT table: 0°/180° turntable, one-face table dimension 800 x 535 mm, work area 800 x 400 mm.
- Max turning diameter: ø1250 mm standard, ø1300 mm with turning diameter enlargement option; max jig height 350 mm standard, 450 mm with low table option.
- Table change repeatability: 0.005 mm in X/Y/Z directions at 335 mm from the center of rotation.
- Bidirectional axis positioning accuracy: 0.006–0.020 mm (ISO 230-2:1988); repeatability of bidirectional axis positioning: less than 0.004 mm (ISO 230-2:2014).
- Spindle motor ratings (10 min/continuous): 12,000 min-1 spec 10.1/7.0 kW; 10,000 min-1 high-torque 12.8/9.2 kW; 20,000 min-1 7.4/5.1 kW.
- Power supply: AC 200–230 V ±10%, 3-phase, 50/60 Hz ±2%; continuous power capacity 10.4 kVA.
- External communication: USB memory interface, Ethernet, RS232C (optional); OPC UA listed; optional fieldbus slaves include PROFINET, EtherNet/IP, PROFIBUS DP, DeviceNet and CC-Link.
- Memory capacity: 500 MB, 3 GB optional; up to 4,000 registrable programs.
