China Professional Horizontal Gantry Milling Machine With The 4
Axises For Machining Railway Boggie
CKM 6232 CNC Gantry/Bridge Milling Machine with movable work-table
adopts Japanese advanced technology of dynamic stiffness, which has
high vibration absorption, more high accuracy, high precision, high
rigidity and stability even under a large torque and heavy cutting.
The machine has multi-functions of milling, boring, drilling inner
holes, ex-circle, flat surface, bench, cone, spherical surface,
grooves etc with a high speed and accuracy. This machine is widely
used for Energy, aerospace, automotive, printing, fabrication,
transportation, military project, rubber, molding, food industry
and so on.
Machine Overall layout
The overall layout is the movable gantry work table of symmetric
structure,including working table base,working table ,left and
right column, beam, slide carriage, Hydraulic system etc.
It’s a is a frame structure made from the left and right column,
the beam and the working table
is equipped with high rigidity iron with adopting resin - coated
sand shell casting process, after casting process, do artificial
aging annealing treatment for the part, after rough machining, do
the second vibrating aging treatment.
The casting has high quality without crack,stomata,shrinkage and
White tissue.After two artificial aging treatment, the casting has
a stable structure and ensure the chemical composition,rigidity and
stability of the material.Product quality certificate provide the
analysis of chemical composition of cast iron,heat treatment report
and heat treatment temperature time curve.
The machine has three CNC feed axis and three axis linkage
achieving high speed and high precision mold processing and also
large torque and heavy cutting machine processing.
The three axis of the machine tool has strict hard and soft limit
double insurance,safety protection to To ensure the safe and
reliable operation of the machine tool.
The machine has a metal telescopic protective cover and the guide
of the cross beam is used in the protection of the accordion.
The machine has automatic chip removal function
The machine has automatic temperature control function
All parts of the machine tools are compulsory and automatic
lubrication
Working table base and working table
The working table is used to reinforce the square box To increase
the density of the tendon of the junction of the base and
column.Greatly improve the rigidity of the machine tool and machine
tool's ability to resist distortion.
We Install vertical high density reinforcing bar below the track
directly undertake the weight of the workpiece and table to avoid
the entire machine in a suspended state and improve the bearing
capacity and deformation capacity of the machine.
The working table uses high density square box and reinforced bar
made from special selection of high strength cast iron. We increase
the height of the work table to avoid the deformation of the beam .
Spindle Motor
The spindle motor is a broadband speed AC servo motor, which
realizes high torque output with low speed and high speed
processing to finish a good roughness, so that it is particularly
suitable for heavy cutting machine and mold parts machining.
The spindle uses Japanese famous brand bearing—p4 grade precision.
It ensures a high accuracy, durability and stability.
Hydraulic System
This machine adopts independent hydraulic station, the main pump,
valve, hydraulic parts are all made of imported products with high
stability, low failure rate, low noise. The hydraulic circuit is
simple and unblocked, which is equipped with automatic temperature
control device to ensure the working stability and extend the using
life.
Control System
The machine is equipped with FANUC CNC Control system. It has high
speed, high precision and high stability features and widely used
for machining complex surface of work-pieces. The machine has X,Y,Z
three feed axis, which can realize three axis association.
