KMT Waterjet System Solutions
Cut Alumium, Cut Titanium, Cut Cakes, Cut Celery, Cut Stone, and Cut much more.....
For over 40 years, KMT Waterjet has been providing waterjet cutting pumps and components to a global network of waterjet table cutting systems integrators who offer entry level to advanced, reliable waterjet machine systems that offer a clean, precise cut on time, every time. The power of water cutting has been harnessed and refined so that KMT Waterjet pumps and the OEM table systems will many materials. Cut aluminum and cut titanium as efficient as possible with KMT Waterjet Systems, bringing true value to the end user—you.
There are a variety of waterjet machine cutting systems including one dimensional multihead conveyor cutting, two dimensional XY cutting, three dimensional XYZ cutting including Bevel & Taper control cutting, 5 axis waterjet cutting and 6 axis Robotic pure water or abrasive waterjet cutting.
Water jets focus high pressure water is then focused into a tight stream by a diamond or sapphire orifice ranging in diameter from 0.004"/0.102 mm to 0.029"/0.736 mm. This water jet stream is used to cut soft materials or is mixed with an abrasive (garnet) to create an abrasive waterjet stream for cutting hard materials.
With either a pure water or abrasive waterjet cutting motion control table system from one of KMT Waterjet's OEM International Network, the 4 applications can be broken down by dimension and complicated 3D shapes:
One Dimensional Cutting • Two Dimensional Cutting • Three Dimensional Cutting • Robotic Cutting
ONE DIMENSIONAL CUTTING
Slitting with a continuous waterjet stream is often used in one dimensional water jet cutting systems. The frame of the system is usually quite simple; waterjet cutting speeds are high and the system is almost always pure water cutting only (no abrasives) using KMT Aqualine Pneumatic Valves Cutting Nozzles. The most important considerations are speed of waterjet cutting, reliability and minimal moisture residue (which is very low due to the high speeds and small waterjet stream).
With one-dimensional waterjet cutting, very small orifice streams are used (as small as .007") and the material moves very quickly beneath the cutting head (in some cases, the head is moving very quickly). For those reasons, water retention on the material is very low and multiple waterjet cutting heads can be used at the same time. One dimensional water jet cutting is commonly used in the food (vegetables and frozen foods) rubber and paper industries.
TWO DIMENSIONAL CUTTING
The most popular application is the 2D waterjet X-Y cutting process. The KMT Waterjet cutting head, using the KMT Autoline II or KMT IDE cutting head moves in X-Y axes, according to the outputs given by the CNC Motion Controller. In many cases, the Z (height) axis is controllable in order to adapt to non-flat or thicker materials; in such cases, the waterjet cutting head needs to be very close to the material being cut. This type of waterjet system is best for rapid production of many different types of parts from different materials.
Important features include the water jet’s cutting speed (some machines move at up to 4,500 inches per minute) and the number of parts to be cut (some water jet cutters have multiple heads, often with the ability for “mirror” or reverse cutting). Machine sizes range from 2' x 2' tables to extremely large tables. There are also many options to consider, including whether to have a saw attached to the table for stone and tile applications or the addition of plasma for certain metal cutting applications.
THREE DIMENSIONAL CUTTING
Three dimensional systems are designed for demanding applications. By using a cutting head with five axes, cones can be cut from flat sheets, holes can be drilled into tubes and ribbed/beveled edges can be produced. While such flexible systems come at a price, they can be used in the most advanced cutting applications and normally pay for themselves as they are extremely versatile:
• Abrasive Cutting
Engine components made in titanium, aluminum and stainless steel; turbine blades, marble and other decorative stone.
• Pure Water Cutting
Components for car interiors such as carpets, door panels, bumpers, dashboards, instrument panels, glove compartments, etc.
In most robotic waterjet cutting systems, the cutting head is attached to a robot arm. For three dimensional waterjet cutting, industrial robots and motion control technology are used, thus providing unrivalled flexibility, which is crucial considering the constant changes made to production processes.
It is, for example, very easy to modify the cutting program so that several tasks are carried out simultaneously. There is no need for a system reset or similar operation. Robotic waterjet cutting is very safe, cost-effective, productive and protect the environment because they provide a viable alternative to conventional machining methods such as sawing, thermal cutting (plasma/laser), punching, milling and other mechanical processes (deburring of cast and forged parts or composites).
Robotic water jet applications are able to cut materials such as headliners, dashboards, door panels and other parts with extreme bends and overall depth. Speeds of cut and part cycle time are very important considerations with robotic water jet cutting systems.
