# Brother M300Xd2-5AX

Hardware · `M300Xd2-5AX` · verification: source checked

The Brother M300Xd2-5AX is a multi-tasking CNC machine that combines milling and turning on a tilting rotary table. It has five control axes (X, Y, Z, A and C), 300 x 440 x 380 mm linear travels, a standard 12,000 min-1 spindle and simultaneous 5-axis machining capability. It uses the CNC-D00v (DB) control and lists OPC UA communication.

## Safety

- Tools 200 mm or longer may contact the jig when the magazine turns, depending on jig height.
- For the 28-tool magazine, turning tools cannot be set in adjacent pods.
- Maximum tool length, diameter and weight are limited by spindle speed, machine configuration and center of gravity; confirm details with the distributor.
- The jig area has interference areas depending on axis movement and tool size; refer to Brother external views or interference diagrams.
- Pallet clamp selection changes the table-top-to-spindle-nose distances; refer to Brother interference drawings.
- A relocation detection device may be required depending on destination; machines with it carry the RD suffix.
- Regular air pressure is 0.4-0.6 MPa with 0.5 MPa recommended; set pressure higher than recommended depending on machine specifications, program or peripherals.

## Study notes

- CNC-D00v (DB) control; simultaneous 5-axis machining is available only on the M300Xd2-5AX.
- Spindle options are 10,000 min-1 high-torque, 20,000 min-1 and 27,000 min-1; the standard spindle is 12,000 min-1.
- Tool storage for the M300Xd2-5AX is 21 or 28 tools; the 64-tool magazine belongs to the M300Xd2-64T variants.
- Table work area is 140 mm diameter with C-axis standard and 170 mm diameter with C-axis high-torque.
- Maximum table load is 40 kg table side with C-axis standard, 75 kg table side with C-axis high-torque, and 19 kg tail side.
- A-axis indexing feed is 60 min-1 with C-axis standard and 50 min-1 with C-axis high-torque; C-axis indexing feed is 200 min-1.
- Required floor space is 1,590 x 2,697 mm for 21 tools and 1,300 x 2,667 mm for 28 tools, excluding coolant tank and chip conveyor.
- Bidirectional positioning accuracy on X/Y/Z is 0.006-0.020 mm per ISO 230-2:1988; repeatability is less than 0.004 mm per ISO 230-2:2014.
- Power capacity is 10.4 kVA continuous; air supply is 0.4-0.6 MPa at 165 L/min.
- OPC UA is listed; Ethernet and USB are standard, RS232C is optional, and PROFINET/EtherNet/IP are optional slaves.
