Cutting other materials

Waterjet cutting - the cost-effective cutting method for a wide range of applications
As nearly all materials can be cut with water jets, the application is extremely versatile. Waterjet cutting is currently used in the processing of many different materials, including

steel, copper, aluminium, brass, titanium, bronze, carbon fibre, Kevlar, Inconel, composites, circuit boards, metal alloys, glass, acrylic glass, stone, marble, tiles, ceramics, bricks, porcelain, timber, leather, rubber, plastics, rock wool, carpets, foams, paper and food.

Waterjet cutting is a particularly suitable method for the production of complex cuts and shapes. The cold cutting method allows for the cutting of virtually any shape in any material. Manufacturers who need to constantly change material and cutting contours are delighted with the flexibility offered by waterjet cutting.
Over the last few years, the requirements for industrial cutting applications have become much more stringent. They concern a number of aspects. Apart from high productivity to cutting speeds, processors wish to cut complex shapes with high precision and good cutting edge quality. Waterjet cutting normally does no require high clamping forces, as the waterjet generally impacts on the material at a right angle. Although the kinetic energy of the waterjet is very high, it does not cause changes to the structure of the material along the cut edge. The method allows for high precision cutting with smooth cut edges and no burrs. As the cut edge quality is generally very good, there is normally no need to rework the parts. The surface of the material remains undamaged. The very fine waterjet produces an equally narrow cutting gap. This means that no material is wasted, as would be the case with all other conventional cutting methods.

Advantages of waterjet cutting with systems from KMT Waterjet:

• 6200 bar technology for fast cutting speeds and excellent cutting edge quality

• Cold cutting method preventing heat affected zones in the material; no material stress or problems in the processing of hardened materials

• Clean end product - no need for reworking

• Burr-free cutting edges - no need for reworking with most waterjet applications

• High precision - no need for recutting

• High cutting speeds

• No need for resharpening tools

• Very fast implementation from drawing board to cut piece

• Short setup time - as tangential forces are minimum, workpieces need normally not be clamped

• Safe for the operator and the environment - waterjet cutting does not produce vapours or dust and the method does not require costly coolants

• Narrow cutting gaps

• Ideal method for the production of prototypes and processes that require high flexibility - successfully used in large serial production

• Optimised utilisation of material with CAD/CAM software

• Global network of sales and service agencies

• 24-hour service and spare parts supply

• Customised system solutions
