The YJ-4020-3L Water Jet Cutting Machine is a large-format, three-axis CNC system manufactured by Yongtao in Foshan, Guangdong, China. It provides a 4000 × 2000 mm cutting area for processing large glass panels and flat sheets without repositioning the workpiece.
Equipped with X-, Y- and Z-axis motion, AC servo control and a vertically oriented cutting head, the machine performs straight 90-degree cutting, curves, internal openings and custom two-dimensional profiles. Its bridge structure, protected linear motion components and ultra-high-pressure system are designed for stable industrial production.
The YJ-4020-3L Glass Waterjet Cutter is primarily configured for flat glass processing. With appropriate cutting parameters, abrasive settings and consumables, it can also process stone, marble, granite, quartz, ceramics, stainless steel, steel plates, alloy steel and aluminum.
The YJ-4020-3L is a 4020 Waterjet Cutting Machine with a maximum cutting range of 4000 × 2000 mm, a 130 mm Z-axis travel and stated cutting accuracy of ±0.1 mm. Its maximum system pressure is 420 MPa, while the normal operating-pressure range is 300–380 MPa.
This model is suitable for manufacturers that need a Large-Format Glass Waterjet Cutter for flat panels, holes, curves and irregular two-dimensional shapes. Because it is a three-axis model with a vertical cutting head, it is intended for straight 90-degree cutting rather than angled or bevel cutting.

Specifications describe the standard configuration currently listed for this model. Final cutting thickness, speed and edge quality depend on the material, glass condition, pump configuration, abrasive specification, nozzle condition, cutting path and required finish. A sample cutting test is recommended before final production parameters are confirmed.
The 4000 x 2000 Waterjet Cutter provides enough working space for large flat sheets and glass panels. Processing a large workpiece in one setup reduces repositioning, protects alignment and makes it easier to nest multiple parts within the available cutting area.
Compared with a smaller table, the 4m x 2m Waterjet Cutting Machine is better suited to factories that regularly receive large panels or need to arrange several components in one cutting program. The 4100 × 2100 mm waterjet cutting table supports a stated effective working range of 4000 × 2000 mm.
The YJ-4020-3L 3 Axis Water Jet Cutter controls movement along the X, Y and Z axes. The cutting head remains vertically oriented, allowing the machine to produce straight 90-degree cuts, curves, holes, slots and irregular flat profiles.
This configuration is appropriate when angled cutting is not required. It also avoids unnecessary multi-axis complexity for factories whose work consists mainly of two-dimensional flat-sheet processing.
The 4020 3 Axis Waterjet Cutting Machine is therefore a practical choice for buyers who prioritize a large working area, straightforward operation and stable CNC path control.
The YJ-4020-3L Gantry Waterjet Cutter uses a crossbeam supported at both sides. This bridge-type arrangement distributes the moving structure across two supports and helps maintain consistent motion over the large cutting area.
High-precision ball screws and linear guides support controlled axis travel. AC servo drives respond to commands from the CNC controller, producing coordinated movement along the programmed cutting path. The rigid structure is intended to reduce unwanted movement during acceleration, positioning and continuous contour cutting.
Water, abrasive particles and cutting residue can shorten the service life of exposed motion components. The machine therefore uses a labyrinth-style waterproof and sand-resistant rail design with dual protective curtains.
Stainless-steel protective covers help shield the guides and transmission components from water, abrasive contamination, rust and corrosion. These protections also simplify routine cleaning around the cutting table.
Protective covers must still be inspected regularly. Accumulated abrasive, damaged curtains or contaminated lubrication should be corrected before they affect axis movement.
The 4020 CNC Waterjet Machine combines an AC Servo CNC Controller with coordinated X-Y-Z movement. The operator prepares the required part geometry, checks the dimensions and cutting path, and transfers the processed program to the CNC control system.
The typical production sequence is:
Prepare and verify the two-dimensional drawing.
Confirm the workpiece dimensions and material condition.
Set the cutting path, lead-in position and part spacing.
Select pressure, cutting speed and abrasive settings.
Position the sheet securely on the cutting table.
Confirm that the nozzle path is clear.
Perform a controlled trial or edge test when necessary.
Start the CNC cutting program.
Inspect the finished dimensions and edge condition.
The AutoCAD-Compatible Waterjet Machine workflow allows drawings created in CAD software to be prepared for CNC cutting. File conversion and toolpath generation should be completed with the software supplied or approved for the machine’s control system.
The standard production system consists of the main cutting units required for abrasive waterjet operation:
4000 × 2000 mm CNC cutting table
Ultra-high-pressure intensifier system
CNC control cabinet
Automatic abrasive feeding system
Cutting head and abrasive delivery components
Recirculating cooling tower
High-pressure tubing and connections
Electrical and servo control system
The high-pressure system delivers a maximum rated pressure of 420 MPa. Normal operating pressure is listed at 300–380 MPa and should be selected according to the material, thickness, piercing method, cutting-speed requirement and desired edge quality.
The 420 MPa Waterjet Cutting System uses a 0.33 mm gem orifice and a 1.0 mm abrasive nozzle in the stated configuration. Maximum water flow is 11.1 L/min, while maximum abrasive consumption is listed at 190 g/min.
The automatic abrasive feeding system and sand valve are designed to maintain stable abrasive delivery. Clean, dry and correctly sized abrasive should be used to reduce flow interruption and premature wear.
The Waterjet Cutter for Large Glass Panels provides a 4000 × 2000 mm processing range for straight edges, curves, internal openings and custom flat profiles. It is suitable for large sheets that fit within the machine’s effective cutting area and load-bearing conditions.
The 4020 Waterjet Machine for Flat Glass follows the programmed path without requiring a dedicated mold for every new profile. This is useful for customized components, sample production, different part sizes and small or medium production batches.
Glass is sensitive to concentrated impact during piercing. The entry position, initial pressure, nozzle height, abrasive flow and lead-in path must therefore be selected carefully.
Piercing should begin away from a critical finished edge whenever the drawing permits. A controlled starting method and appropriate pressure can help reduce the risk of cracking or chipping. Actual settings must be verified using the same type and thickness of glass intended for production.
The CNC Glass Waterjet Cutting Table can produce clean contours and internal openings, but the final edge quality depends on cutting speed, abrasive quality, nozzle condition and the required finish. Secondary edge treatment may still be required when the finished product has strict visual, handling or installation requirements.
Tempered glass should normally be cut before tempering. Cutting fully tempered glass can release its internal stress and cause the entire sheet to break.
Although this model is positioned as a 4020 Glass Waterjet Cutting Machine, its abrasive cutting system can process several categories of flat material when the correct parameters are used.
Suitable material categories include:
Glass panels
Stone and marble
Granite and quartz
Ceramic materials
Stainless steel
Steel and alloy steel plates
Aluminum sheets
The listed maximum cutting thickness is up to 50 mm for glass, stone and ceramic materials and up to 40 mm for metals. These values should be treated as configuration limits rather than guaranteed production results for every material.
Before accepting a production order, the factory should verify the material grade, thickness, dimensions, required tolerance, acceptable edge quality and expected cutting speed through a sample test.
The machine’s stated cutting accuracy is ±0.1 mm, and its stated repeatability is ±0.05 mm. These figures describe the machine configuration under suitable operating and maintenance conditions.
Actual finished-part accuracy can also be influenced by:
Cutting-speed selection
Kerf compensation
Nozzle wear
Abrasive consistency
Material movement
Piercing method
Drawing accuracy
Workpiece flatness
Machine calibration
Required edge-quality level
For critical work, measure a representative test piece before batch production. The inspection should record the material, thickness, pressure, speed, abrasive setting, nozzle combination, measured dimensions and edge-quality acceptance criteria.
This type of verification provides more useful production evidence than relying on a single nominal accuracy figure.
Reliable cutting depends on the condition of both the motion system and the high-pressure components. Recommended routine checks include:
Remove accumulated abrasive and cutting residue.
Inspect protective curtains and stainless-steel covers.
Check ball screws, linear guides and lubrication points.
Confirm that the abrasive valve feeds consistently.
Examine the gem orifice and abrasive nozzle for wear.
Inspect high-pressure tubing, fittings and connections.
Monitor the intensifier and cooling system.
Verify axis positioning and repeatability.
Check water quality and inlet conditions.
Keep maintenance and replacement records.
The sand valve should be kept clean and dry to prevent unstable abrasive delivery. Worn nozzles should be replaced before the enlarged cutting stream affects kerf width, accuracy or edge quality.
The main units are packed separately for transport:
| Component | Approximate packaging dimensions |
|---|---|
| Cutting table | 5.1 × 3.2 × 1.65 m |
| High-pressure booster system | 1.3 × 0.95 × 1.25 m |
| Abrasive feeder | 0.6 × 0.6 × 0.95 m |
| Control system | 0.65 × 0.65 × 1.67 m |
Before ordering, the buyer should confirm workshop access, unloading capacity, foundation conditions, operating space, power supply, inlet water, drainage, cooling requirements, compressed air requirements and local electrical standards.
Adequate clearance should be reserved around the table, high-pressure system and control cabinet for operation, cleaning and maintenance.
