Application and advantages of PMT waterjet
cutting:
PMT Waterjet Cutting Machine is an effective tool
for any shape of artistic creation. The
traditional cutting method is saw cutting only in
a row. When cutting the curves, the model should
be made according to the size and then polished.
Waterjet Cutting Machine can cut any shape of
models under the control of the CNC
program.
1. Smooth cutting
quality is
perfect.
2.The cutting accuracy of waterjet
cutter is up to 0.1mm. Edge joints are
regular, and water jet cutting can also
make very complex puzzles and
murals.
3.Cutting speed is fast, and product
consistency and interchangeability are very
good.
4. Drilling, cutting and forming can
be done at
once.
5. Improve the working environment
and reduce the impact of dust and noise on
the
operator.
6. Waterjet cutting is a cold cutting
that does not damage the internal structure
of the
material.
7. It is the only machine for
processing composite materials and fragile
porcelain.
8. Waterjet Cutter can cut metal,
rubber, foam, plastic, composite materials,
stone, ceramic tile, marble,glass,
etc.
Product Description
50HE High presssure pump structure includes water
supply system, hydraulic system, and the intensifier system
(or named high pressure system).
water supply system
The main engine needs two water sources for cutting and
cooling, thus we need two drainages: the
cooling water drainage and the water leakage drainage.
Special definition is listed below:
Cutting water: The intensifier must be supplied with water
of 20-1000psi (1.4-6.9bar). The input
water should not less than the output water by 1.5 times.
If the water source contains dissolved
solid(esp. silicate and calcium), the orifice life would be
shortened. If the filter system cannot
correct the water quality, extra water treatment facility
must be installed.
Cooling water (for the heat exchanger): The heat exchanger
is used to adjust the accumulated heat
in the hydraulic oil. The hydraulic oil functions the best
at the temperature of 40 ºC.The cooling
water is first led to the heat exchanger for the
intensifier and then to the exchanger for the
hydraulic oil pump. The cooling water flow should be enough
as to ensures that the temperature in
the oil tank is lower than 43 ºC. The standard water flow
is 11 lpm for each power horse at
15ºC.The water contains a little minerals and acid will be
helpful to thermal transmission and the
prolongation of the heat exchanger life.
Hydraulic system
The hydraulic system consists of pressurization,
filtration, and cooling systems. The
intensification principle is: a motor of 37kw drives the
hydraulic pump, then the pump will
pressurize the hydraulic oil up to 20Mpa max. The
pressurized oil is pushed into the oil cylinder
through the electro-hydraulic directional valve. There is a
sensor on either side of the oil cylinder.
The directional valve will receive a signal when the piston
inside the cylinder is approaching to
one end of the cylinder. The piston will travel to and fro,
making the high pressure water
continuously.
The filtration system is three steps filtration. They are
oil filling filtration, outlet filtration, recycle
filtration.
waterjet Intensifer system
The intensification system mainly refers to the
intensifier, but it also includes other components in
the water circuit that make the lower pressure water into
high pressure water. Specifically, it
includes intensifier, accumulator, high pressure tube,
connector etc.
Intensifier is main part of the intensification system. A
section for the intensifier 's principle,
structure, and maintenance is contained in this manual.
Electrical control system
The electric control system is integrated into the control
panel, including PC, control circuit. This
control system is used to start/stop the main engine and
adjust the speed.
The function of the display, buttons and knobs on the panel
is listed below.
"power indicator" controls the power.
"voltage meter" indicates the working status of the PC.
"currency meter" displays the currency of the motor of
18kw.
"master switch" switch for the general power supply.
"Pump & main engine switch" start/stop the main motor
"high pressure/abrasive switch"
"emergency stop"

Cutting Table
Attributes:
PMT waterjet cutting table consists of transmission part
with X axis, Y axis and Z axis, water tank, cutting head,
lubrication part and servo driving system. Gantry
mechanical structure is fit to large size machines, long
running distance of X and Y axis, suitable for processing a
variety of complex big size parts.
The cutting table is a 2-D pc-controlled table, consisting
of Y-axis, catcher, X-axis, Z-axis (cutting
head rest), cutting head, high pressure hose, and the
abrasive box. Both the X-axis and the Y-axis
are installed with linear guide and ball screw. The control
system instructs the servo motor which
drives the ball screw. The cutting head assembly (Z-axis)
is installed on the ball screw, so that it is
realized to start, stop, shift, and change the speed of the
cutting head rest. The X-axis travels
alongside with the Y-axis, and the Z-axis travels alongside
with the X-axis. The positive and
negative direction is defined as follows: standing in front
of the cutting table, your left-hand side
is negative direction of X-axis, the opposite direction is
positive; the X-axis 's advancing direction
is positive, and the opposite is negative. Being instructed
by the control panel, the X and Y axis
moves together, leaving the sophisticated picture on the
workpiece accordingly.
Y-axis is actually working as the base of the cutting
table. It is welded with a polished surface, on
which the linear guide and the bearing housing for the ball
screw are fixed. The linear guide is
used to guide the X axis's travel and support it. The
servo-motor is installed on the driving end of
the screw ball and the decorative panel is also attached to
the Y axis.
The linear pair and the ball screw pair ensure the accuracy
of the travel and make the action of
starting, stop, shift and speed change highly reliable. In
order to ensure that the cutting head rest
travels accurately, the X axis is also equipped with linear
pair, ball screw pair, and servo motor.
PMT waterjet cutting machine suitable glass cutting,marble
cutting ,ceramic tiles cutting,and metal cutting , that
real one good cutter machines for many materials.
