How much thick material abrasive water jet cutting machine can cut? |
|
This can range anywhere from a 0.1 mm up to 300mm thick. It varies with the softness or hardness of the material being cut. Hard materials are normally cut up to 150mm thick. This does not mean Stainless Steel or stone with a higher thickness cannot be cut with a waterjet. It all depends on the purpose for which cutting is done (i.e. prototype, production, etc.), system’s operating conditions, HP Pump capacity and on the desired cut finish. It also depends on how long you are ready to wait for nozzle travel, as and when thickness increases, cutting speed decreases. For all materials, adjustments can usually be made to produce required results and if needed higher capacity pump is used. Following list shows possibilities of cutting different material: |
|

Slitting Operations/ Trim & Hole cuts |
Corrugated box board & paper(where product wetting is not crucial), cement sheet, food(meat, sea food, bakery items etc.) |
Institutes |
To teach waterjet m/c as an innovative cutting technology to students, many of the larger size institute that offer engineering classes also have waterjet to provide job-shop services to other departments, to do R & D, to make projects. |
Job & Machine Shop Application |
Job and machine shops use the unmatched versatility of waterjets to expand their capabilities beyond what is possible with machining centers, lasers, EDM of mills, when using watejet they can throw out pre-conceived ideas which are traditionally considered as a “Difficult Application”. |
Medical / Surgical |
To blanking out surgical instrument from special steel alloys, cutting artificial limb components, in manufacturing carbon braces and orthopedic application appliances, making prototype. |

Compare water jet cutting with other conventional method? |

 |
What is the difference between stepper motor and servo motor? |
|
Technical Differences of Servo & Stepper drives |
|
 |
Our CNC cutting table can be separated to two types according to different control system. The system can be separated to A type and B type. A type adopts stepper system, but B type is servo system. |
 |
Stepper system is called economic system. Three units of the control system (CNC controller, drive power and stepper motor) are all made in China. We generally call servo system as high-grade system. |
 |
In consideration of its operation property, the two-control systems have differences in several aspects. You can choose one according to your actual situation: |
|
Control accuracy: |
The control accuracy of stepper system is 0.01mm, but for the servo system it can achieve 0.001mm. The accuracy of products processed by water cutter mainly depends on abrasion of abrasive. So no matter what kind of control system chosen, the cutting accuracy can be controlled in + 0.1mm. |
Move speed: |
The largest curve move speed of stepper system can be 1500mm/min, but the servo system can achieve 5000-8000mm/min and even faster. So if your material is elastic texture and cutting speed exceeds 1500mm/min, you should choose servo system to guarantee the cutting efficiency. |
Reliability: |
Servo system entirely adopts products of world famous brand, so it can be more reliable. |
Price: |
With the same pressure system and cutting table, the price of equipment with servo system is higher than stepper system. |
|
|
The drive power of servo system is total numerical. |
