Space saving

While ensuring large jig area,
the space-saving design makes
factory
machinery layout easier and maximizes
the effective use of installation space.

*1 Dimension including coolant tank

*2 Compared to BT40 horizontal MC with equivalent travels

Energy saving

Achieves exceptional low power
consumption
through diverse functions enabled by accumulated technology.

*Compared using a sample program created by Brother

Air saving

By optimizing air-related functions such as air purge and spindle air blow, and reducing wasted air consumption, it achieves both energy savings and high reliability.

*Compared using a sample program created by Brother

Energy savings mode

Added a function to turn on/off energy-saving functions simultaneously.
Items to be turned on/off can be customized.

Work light, coolant pump, etc. are turned OFF simultaneously.

2 Comparison with
multiple 3-axis
machining centers

Enables process integration

Process division

For 3-axis and 4-axis machining
Process division is required,
resulting in mounting error.

Cycle time is short,
but balancing the machining time is necessary.
The impact of process changes is significant,
requiring time-consuming process design.
Technical expertise in jig design is required
to ensure machining accuracy.

Process integration

Process integration with 5-axis
machining ensures
highly-efficient machining.

Cycle time is longer, but
machining time balance adjustment is easy.
Shorter process design time.
Equipment can be increased in minimal units
based on production fluctuations.
Reduce workpiece mounting frequency and
ensure multi-face machining accuracy easily.

High-speed,
high-accuracy
simultaneous
5-axis machining

High-speed, high-accuracy simultaneous
5-axis machining is realized with an algorithm
that enables maximum acceleration and deceleration at all times.

Tool center point control

Machining is performed by changing the tool direction relative to the workpiece.
Optimal acceleration/deceleration are performed by
look-ahead up to 1,000 blocks.

Processing speed of
minute line segments

CPU performance has been greatly enhanced, and processing speed is now four times faster, enabling
high-speed processing of CAM data with small
tolerance.

Vertical machining center +
tilting rotary table

Interference occurs with the base of the tilting rotary table when the rotary axis is rotated 90° or more.

Jig design is restricted by areas of interference.
The support is different for
the machine body and rotary table.

HU550Xd1

Fewer interfering areas
means fewer jig constraints.
The integrated rotary table enables
centralized support.

High-accuracy tilting rotary table designed for large jigs

Brother’s original large tilting rotary table with a roller gear cam mechanism and tandem control,

achieving both high speed and high accuracy.

Roller gear cam mechanism

A roller gear cam mechanism is used for A and B axes, achieving both high speed and high accuracy.

Flexibly adaptable
to complex jig configurations.

Allowable inertia	Standard	High inertia mode
Around A-axis	6.0kg・㎡	-
Around B-axis	4.1kg・㎡	8.8kg・㎡^*1

*1 Parameter adjustment is required.

Tandem control

Tandem control using two motors is used for the A-axis. This suppresses distortion in the large tilting rotary table, enabling high-speed indexing.

Synchronous control of two motors
contributes to high productivity.

Axis	Indexing time [90°]	Max. indexing feed rate
A-axis	1.2sec	50min^-1
B-axis	1.2sec	75（60^*2）min^-1

Reliability

Stable production
with diverse functions

High chip evacuation

Optimal machine design ensures efficient evacuation
of chips during machining,
maintaining stable production.

Approx. 98% or more of chips are evacuated

Center
trough structure

The inclined base and the center trough structure effectively evacuate chips that fall on the base to the outside of the machine.
Head shower
(option*2)

A head shower is available to remove chips from the spindle head.
Magazine cover
ATC shutter

The magazine is separated from the machining chamber by a shutter to minimize the effect of chips on tools.

*1 Value based on our in-house tests.

*2 Included with the coolant nozzle (optional).

Stuck chip detection function

Equipped with a stuck chip detection function, widely used in our vertical machining centers. Machining defects are prevented by detecting the stuck chips that caught between the spindle and the holder during ATC. Troublesome short-period stoppages can also be reduced by automatically cleaning and retrying.
