CNC water-jet cutting machine composed of cutting table, high-pressure pump, CNC control system with cutting software, cutting head, high-pressure water valve, and sand controlling system.
Auto abrasive feeding system and water cooling system are included.
Optional systems available: water softening system and auto sludge removal system.
Cutting Table
Structure Feature
Cast beam and Y-axis base frame provide excellent precision and stability.
Table body and water tank are sub-aspect structure, lessening pressure of sands and machined parts on moving parts.
X-axis and Y-axis transmit to rolling nut ball screw mandrel.
Controlling System
Naiky controlling system with Mitsubishi AC servo digit driving system and AC servo motor.

Transmission System
Hiwin (Taiwan) lead rail and TBI (Taiwan) ball screw to ensure accuracy and quality.
Prevention System
Over travel auto spacing function and soft spacing function.
Unique prevention design: new mazy protection and Z-axis totally enclosed design prevents sand and water from eroding the guide screw and lead rail.
Lubrication System
Auto mass lubrication system to make oil reach every oil site on time and make table steadier and easier.
Cutting Head Assembly
Cutting head assembly with rectification function to lessen assembly time; changing wear parts is simple.
High-pressure water switch: air valve can open and close the HP water valve instantaneously; with CNC, HP water can be controlled automatically; blockage pressure can be adjusted for low-pressure operation.
Abrasive feeding system: dynamic sand feeding; manual sand makeup for the feeder (assisted with sand meter; auto feeder can realize automatic feeding).
High Pressure Pump
Intensifier Systems
HP generator: single pole two-way plunger type intensifier; major parts imported from the USA (Accustream/Hypertherm) including check valve body, high-pressure cylinder, check valve repair kit, on/off valve repair kit, high-pressure seals.
Major motor: Siemens; USA pipeline; single-row type water filtering system (5 micron, 1 micron, 0.45 micron parallel); manual pressure regulation function; extra pressure auto stop and protection; three-ply safeguards.
Tools: special tools (list 1).
Random fittings: additional wear parts (list 2).
Hand-book included.
Technical Parameters
General data: maximum output flow 3.7 L/minute; maximum orifice 0.3 mm; maximum output pressure 420 MPa; intensifier configuration single; pressure control manual; shifting control electro-hydraulic control.
Pump power: motor power 37 kW/50 HP; voltage 380 V/50 Hz (220 V available); options air cooling/water chiller.
Cnc Controlling System
Cnc Configuration
17-inch LCD liquid crystal display.
DNC on-line working function.
Functions of returning arbitrary point, bending, and circular arc working auto deceleration.
Function of cutting figure imitation display.
80 GB memory hard disk.
Mitsubishi AC servo driver and motor.

Software
Change DXF document from AutoCAD into numerical control process.
Serial communications between PC and CNC.
Open database can shore parameters; just click the material, parameters will be loaded automatically.
Calculate length of line and time automatically.
Control cut-out and cut-in automatically.
Cutting track auto imitation function.
Functions of lessening speed on the corner, remanding material bridging, and lancing.
Auto Abrasive Feeding System
Abrasive Meter Regulator
Dynamic sand feeding; dynamic type comes over traditional type; manual type makes operation easier; with CNC, abrasive can be controlled automatically.
Abrasive Hopper
Side-hanging sand hopper; window on side face reminds workers when to feed sand; provides sand consumption every time after it is filled up.
Abrasive Tank
Provides functions of shoring and sanding sands for the machine; improves automation and lessens labor intensity; capacity 170 liters; high accuracy.
Auto Cooling System
Auto Air Cooling System
Working environment is clean and tidy; good control of hydraulic system oil temperature.
