CNC Water Jet Cutter

General Description
The CNC water jet cutter is mainly constituted by the CNC cutting platform, high pressure system, CAD or CAM software system, cutting head, high-pressure water switching valve, sand control system and the other components. You can also configure it with other optional systems like the automatic grinding material supply system, water softening system, oil cooling system, etc.

Regarding to the export packing mode, we usually apply the honey comb pallet box to pack the high pressure system and the control system. As for the other systems and components, nude packing is our practice.

The automatic centralized lubrication system ensures that the lubricating oil timely reaches each lubricating point of drive system, thus this machine can work stably and reliably with simple maintenance.

Abrasive Cutting System
This system of CNC water jet cutter is mainly comprised of the all-in-one abrasive cutting head, high pressure water switch, grinding material gauge, control valve and the sand hopper.

1. All-in-one Abrasive Cutting Head
This independently developed cutting head is a high-efficient one in the current water jet cutting industry. It comes with automatic adjustment function to save the assembly time. All the quick-wear parts can be easily replaced.

2. High Pressure Water Switch
a. This switch utilizes a pneumatic valve that can realize instant opening and instant or delayed shutting of high-pressure water flow. The CNC auxiliary function helps to achieve automatic control of high-pressure water.
b, The blockage pressure can be freely adjusted to achieve low-pressure perforation.

3. Sand Feed System
The CNC water jet cutter adopts the self-suction continuous sand feed mode. Manual sand supplying is achievable. Automatic sand feed will be available if the automatic sand feed system is configured.

4. Sand Control Valve
a. The electric sand supply mode is used to overcome the defects of traditional self-suction sand feed mode.
b. Instead of the electromagnetic valve, a pneumatic valve is adopted. Thus, sand blockage or stoppage caused by failed magnetism can be avoided.
c. Manual operation of sand flow via the speed regulating motor is attainable, allowing for easy operation.
d. With the CNC auxiliary function, the supply of grinding materials is automatically controlled.

5. Sand Hopper
The side hanging sand hopper utilized by the CNC water jet cutter comes with a side window for observing grinding material using conditions for informing the operator to timely supplement the sand. A fully loaded sang hopper can afford sand consumption of continuous 15 to 30 minutes.

High Pressure System (Optionally KMT or Accustream)

1. Technical Features
Conforming to the CE standard, the high pressure system stably and continuously works for 24 hours with stable pressure without fluctuation. The perfect automatic diagnosis and protection function is available. What’s more, the key components are introduced from American or German brands.

2. Safety Protection System
The hydraulic system enables double filtration to ensure the operation safety and the water inflow adopts 3-level fine filtration from 5μm, 1μm to 0.45μm. Thanks to the oil temperature detection and protection device, the CNC water jet cutter will automatically stop once the temperature is over 60°C. In addition to the oil temperature alarm, multiple alarm devices are configured, including the underpressure, overpressure, blockage and over hydraulic alarm devices.

3. Main Configurations
The low pressure oil pipeline adopts the imported reliable C type conical connector which is high pressure resistant and easily maintained. The ceramic piston as well as the imported original high pressure and low pressure oil seals are equipped to ensure the stability and life span of the whole system. The high pressure oil pipeline is equipped with a stiff conical seal and the sealing effect is remarkable.

4. Automatic Air Cooling System (Optional)
This system performs forced cooling towards the hydraulic oil and improves the running conditions of the hydraulic system, thus the continuous working time and the service life of the CNC water jet cutter is extended.

5. Cooling System of Circulating Water (Optional)
This system better guarantees the continuous working condition of hydraulic system, saves the precious water resource, and also ensures that the oil temperature is below 55°C.

6. Automatic Grinding Material Conveying System (Optional)

This system is simple, reliable and free from maintenance. The high-sensitivity sensor and the signal light inform the operator of adding the sands into the container at the right time. 170L sand is enough for 500 to 800 minutes cutting processing. Besides, this system enables to simultaneously and automatically supply the sands for two sets of CNC water jet cutters.

7. Water Softening System (Optional)
