# Brother H550Xd1

Hardware · `H550Xd1` · verification: source checked

The Brother H550Xd1 is a horizontal machining center with a BT30 spindle and a B-axis table. It has 550 mm X, 400 mm Y, and 400 mm Z travels, a 30-tool magazine, and a 400 x 400 mm table rated to 400 kg. The B-axis table uses a roller gear cam and indexes at up to 100 min-1.

## Connected

- Manufacturer: [Brother](https://machineschema.com/manufacturer/brother.md)
- Protocols: [EtherNet/IP](https://machineschema.com/protocol/ethernet-ip.md), [OPC UA](https://machineschema.com/protocol/opc-ua.md), [PROFINET](https://machineschema.com/protocol/profinet.md)

## Safety

- Max. table load inertia is 3.4 kg·m² in standard mode and 5.4 kg·m² in high inertia mode; high inertia mode requires parameter changes.
- When attaching an adjacent tool, the combined diameter of the tool and adjacent tool must be less than 130 mm.
- Maximum tool length is 250 mm, maximum tool diameter is 125 mm, and maximum tool weight is 4.0 kg per tool; total tool weight is 50 kg.
- When the jig area is expanded to ø800 mm, the tool must be moved to a safe position when the B-axis rotates or when tool length is restricted.
- 7 MPa CTS is available only for the BBT specification.
- A relocation detection device may be required depending on destination; machines with it carry the RD suffix.
- Regular air pressure must be 0.4 to 0.6 MPa (recommended 0.5 MPa) and required flow is 45 L/min.

## Study notes

- Horizontal machining center with BT30 spindle; jig area is ø600 x 580 mm and can be expanded to ø800 mm with restrictions.
- B-axis table uses a roller gear cam mechanism and indexes at 100 min-1; clamp torque is 670 N·m.
- B-axis indexing time is 1.0 s for 0→90° and 1.1 s for 0→180° in standard inertia mode.
- Tool change times are 1.3 s tool-to-tool and 2.7 s chip-to-chip; spindle start/stop is 0.15 s or less for the high-torque specification.
- Controller is CNC-D00 with a 15-inch color LCD touch display, 500 MB memory (3 GB optional), and 4,000 registrable programs; only NC language is supported.
- Main spindle motor is listed as 10.1/7.0 kW (10 min/continuous) for 12,000 min-1; optional specs are 12.8/9.2 kW for 10,000 min-1 high-torque and 7.4/5.1 kW for 20,000 min-1.
- Rapid traverse is listed as 50 x 50 x 56 m/min in the overview and 50 x 56 x 56 m/min in the detailed table.
- Accuracy: bidirectional positioning X/Y/Z 0.006–0.020 mm; repeatability less than 0.004 mm; B-axis 28 sec positioning and 16 sec repeatability, measured to ISO 230-2.
- Power capacity is 10.4 kVA continuous; machine height is 2,497 mm; required floor space is 1,557 x 2,743 mm (3,581 mm with control unit door open).
- Network options also list CC-Link master/remote device, PROFIBUS DP slave, and DeviceNet slave, which have no matching protocol ids.
- Optional features include BIG-PLUS dual contact spindle, CTS at 3 or 7 MPa, vibration adjustment, and 20,000 min-1 spindle.
- Tool change time measurement references JIS B6336-9 and MAS011-1987.
