Triplex direct drive waterjet cutter

Advantage of triplex waterjet is its low power consumption and small size. Diesel engines are often used with triplex direct drive waterjet due to this low power property. Direct drive pumps are also of high power efficiency. Hydraulic intensifiers losses power due to heat generation with in the hydraulic system. In general, triplex pump waterjet does not require special cooling system. The small size advantage of direct drive waterjet also makes it a good choice of portable waterjet application. IWM provides reliable and low cost triplex direct drive waterjet cutting machines.

Tilted cutting with 4 axis or 5 axis waterjet machine

In order to remove taper on the edge of cutting with normal waterjet, IWM offers tilted waterjet head with 4 or 5 axis CNC control. With tilted cutting head, the taper is only on the scrap side of the material and effectively no taper on the edge of the part. In addition, with the 4 axis or 5 axis waterjet, purposely titled edge on the part is achievable. This enables waterjet to cut complicated 3D parts.

Metal cutting with CNC plasma cutters

For metal cutting applications, plasma cutting is often the cost effective alternative. IWM provide stand alone CNC plasma cutting machine, or a CNC cutting system with the combination of waterjet and plasma cutting .

New IWM CNC plasma tube cutting machine

For cutting tube and beam applications, IWM has recently developed CNC plasma tube cutting machine, which can be used to cut square tubes, rectangular tubes, angles, H beams, C beams, and other shapes of beams.

Other high pressure products:

Portable waterjet cutting machine

There is huge need for portable waterjet cutting machine with applications ranging from dismounting wrackage, to field structure repair such as pipe cutting, and even for large sized tyre (OTR tires) cutting. IWM offers Waterjet machine can cut OTR to reduce size to get ready for next shredding process. CNC programmed waterjet machine can optimize the cutting speed for improving throughput and cost reduction. One CNC waterjet machine is suitable to cut differnt sizes of OTR. When used at fields without electric power, diesel engine or diesel generator can be used.

Conventional waterjets pressurize water to high pressure and then mix water with abrasive just before water exits the cutting head. Abrasive is accelerted by high speed water in a mixing tube to receive kinetic energy. Within the 3 or 4 inches length of mixing tube, energy transfer is not very efficient and puts on high requirement of ultra high pressure. However, there is a speical kind of design portable waterjet cutters that pre-mix abrasive with water before it gets pressurized. This enables abrasive to get high kinetic energy at lower pressure with less power driving the pump so that the watejet pump can be made small and light in weight. This kind of portable waterjets are often used for emergency rescue and some other special situations and are not designed and made to be used for heavy duty and long lasting work.

Water blasting with waterjet

With the advanced technology, IWM also manufactures multi-nozzle high pressure jet cleaning machines, also known as water blasting. The water jet (spray cleaning) is for cleaning of hard to reach and/or hard to scrub locations. The water blast cleaning is often used to remove paint or rust, or clean the internal of pipes. The advantage of water blast cleaning is that it does not creat health killer dust as sand blasting, and does not damage the surface of parts to be cleaned. More details of high pressure cleaning machine.

High Pressure Sensor

Another high tech product IWM can supply is ultra high pressure transducer or sensor. The pressure range of measurement is up to 14000Bar (200 KPSI, 1500Mpa). Standard transducer output is 4-20mA. Normalized 0-10 mA current output or voltage output is also available. This pressure transducer is especially useful in a feedback loop of pressure control for applications such as waterjet cutting machines. Find more details of high pressure transducer. The pressure sensor/transducer is often combinded with an IPCI Digital Instrument as read out and control output device. Most common application of such pressure sensor is on a cnc waterjet cutter.

Precise high water pressure generator

In some cases, other than jet cutting applications, there is need to have a kind of high pressure source for testing products that will work under pressure. High pressure water is a good media for ultra high pressure source because of its low compression ratio compared to air. The fact that water does not get compressed much of its volume at high pressure makes it less risk of explosion. The same low compresion ratio property also makes it quick to increase/decrease pressure with water and save process time. WM can provide equipment as high pressure souce up to 60,000 psi. The pressure can be controlled at incremental of 20 psi.


Comparison of major cutting tools:

Waterjet machines -- fast speed, able to cut thick material, good accuracy and finishing surface. The most outstanding advantage is its versatility, it cuts virtually anything with no heat affected zone(HAZ). The second advantage is its ability to cut thick materials, metal or non-metal. This puts water cutter ahead of laser and plasma cutters. Laser cuts fast, but mostly for 1/2 inch or less thick metal, not to mention laser machine price is usually much higher than that of high pressure water cutting machine. High power plasma can cut thicker metal, but the result edge quality is poor, and it can not cut on non-metal. Water cutter is widely used as cutting machine for metal, glass, ceramic tile, marble, and granite. When cutting metals, some burr occurs near cut. Typically, waterjet can cut thickness as much as 4" of steel (100mm). Parts cut by water jet has little or no burr at the edge. In addition, no dross or slag as the result of water jet cutting. The price of waterjet various from $30,000 and up. Check out IWM's current Waterjet on Sale promotion.

Wire EDM -- slow cutting speed, but it is able to cut very thick material. EDM has very high accuracy and excellent surface finish. No burr, a little HAZ. The down side is only electrically conductive materials can be cut with EDM. Also there must be a way to drill a hole for putting through the wire for cutting. EDM is slower than waterjet cutter.

Laser -- good speed and precise cut when cutting thin material. Laser yields little burr, a little HAZ. Laser is suitable to cut non-reflective mild steel. A 6kw laster can cut as much as 25mm (1 inch) steel. Laser cutting system is also of high price than other cutting tools.In general Laser cutting is faster than that of waterjet cutter.

Plasma -- cuts at high speeds and generates heat that leaves rough edges. Distortion and Warpage are often seen when thin metal sheets cut by plasma due to high temperature. Accuracy is not very high with plasma cutting. Plasma cutting can cut electrically conductive materials, up to 6" of aluminum. Process yields HAZ. Special gas need to assist the process. Reasonable price of machine.

IWM is now gladly to offer you option of adding plasma cutting on cnc water jet cutter to enable you to cut metal sheets with faster plasma cutter and to cut thicker metal or non metal materials with waterjet.
