HIGH RIGIDITYCROSS BEAM
The cross beam is designed with high
strength “Internal Circular Wall”,which
features excellent torsion-resistant
capability,and suppresses cross
beam’s structural deformation caused
by the big span between slideways.

HIGH RIGIDITY TABLE
The table is double-wall constructed to
enhance its rigidity and effeceively
increases machining stability.

X,Y-AXIS ROLLER WAYS Z-AXIS BOX WAYS
The X and Y-axis are mounted with high
speed heavy duty roller ways ; while the
Z-axis is box way designed for heavy load.
OVERSIZED BALL SCREWS
The X and Y-axes ball screws are Φ63mm
resulting in enhanced regidity.
RIGID SADDLE
The cross beam saddle is equipped with 5 slide
roller blocks to enhance cutting rigidity and
capacity of the Z-axis.
The Z-axis is designed with box ways to
ensure outstanding stability during cutting.

CONTROL PENDANT
The ergonomic design of the control pendant
provides added convenience of operation.
CENTRALIZED PNEUMATICCOMPONENTS
The pneumatic systems are deployed
together for convenient air regulating
and easy maintenance.
ABSOLUTE POSITIONINGCONTROL
The 3 axes are installed with external
position encoder, providing a
close-loop positioning control.
HIGH STRENGTHSTOP BLOCKS
The 3 axes ball screw seats are supported
with stop blocks to increase axial rigidity
and enhance accuracy.
TWO HYDRAULIC CYLINDERSFOR COUNTER-BALANCE
The Z-axis gas is counter-balanced
by two hydraulic cylinders.
Automatic counter-balanced adjustment
assures high accuracy.
LED WORKING LAMP
The standard LED lamp features high brightness,
long life and is water-proof, IP67 protection grade.
The LED working lamp is directly mounted
above the spindle providing a clearer
operating space.

STEPPED CROSS BEAM
The slideways on the cross beam is
developed in step manner,capable of
sustaining heavy load , and increased
axial motion stability.
POWERFUL GEAR-DRIVE SPINDLE
The spindle is driven by a powerful gearbox
with 30mm thick gear (conventional gear
thickness is 20-25 mm)resulting in heavy
cutting capability.
COOLANT STOPPLATE ON X-AXIS
The telescopic guard on X-axis is equipped
with an additional plate that reduces the
possibility of chips and coolant entering into
the machine interior.
AUTOMATICLUBRICATION SYSTEM
The centralized automatic lubrication
system features pressure detection to
prevent oil blockageand to avoid severe
wear caused by lubrication failure.
LINER SCALES ONTHREE AXES (OPTIONAL)
Heidenhain or Fagor linear scales are avaliable
to achieve higher positioning accuracy.
COOLANT THRUOGHBALL SCREW
Coolant through ball screw is utilized to
limit thermal deformation on the ball screw
caused by thermal growth,resulting in higher
precision machining.

SIDE-MOUNTEDCHAIN TYPE ATC
32 tools (Standard)
40 / 60 tools (Optional)
The ATC with automatic door is dependently
mounted to avoid contamination from cutting
chips and coolant.
The magazine accommodates
BT 50 tool shank.
Random tool selection allows
tool change to be accomplished
quickly in only 8 seconds.

the sales personal of Maxmill.
The heigten of vertical working area calculates by spindle nose
to table.The working heighten will be reduced according to the
using tool length.D&E : Table center to Spindle Nose.If inqiury
tavel is big than D&E, Please contact our sales person
firstly.Horizontal machining (for X axial) : Working area is
between both spindle noses.Horizontal machining of “C” is 90 degree
