WHAT MATERIALS

Will I be Cutting?

With many other alternative cutting methods, the types of materials that are needing to be cut is the first point that you should focus on. However, because Waterjets can cut almost any material, the material to be cut is not so important. While almost any waterjet can cut almost any material, some machines are still better suited to certain materials. For example, when cutting steel you will typically choose a more powerful and a more accurate waterjet, so that you can cut it faster with more precision, compared to if you were cutting glass. Before we move on, let’s have a look at the range of materials that you can cut on a waterjet. Waterjets can quickly and accurately cut soft materials such as; rubber, foam, cork, and other gasket material with a pure water stream.

When cutting harder materials an abrasive is added into the stream. You can then cut almost any material, over a very wide range of thicknesses, for example;

VIRTUALLY ALL METALS

including hardened tool steel, stainless steel, aluminum, opper and titanium

NON-TEMPERED GLASS

including multi-layer laminated safety glass

Composites

Laminates

Stone

Most ceramics

Parts Will I Be Cutting?

Waterjets are great for both short run and prototype parts, but also for higher volume production application. The reason why waterjets are suitable for both has to do with the software that they are controlled by. Techni’s advanced control software can automatically program the cutting path of a desired part directly from a CAD, drawing meaning set up time is reduced between cuts. All you need to do is lightly secure the material in place, enter the material type and thickness into the control computer, and the machine will do the rest. This software capability is great for short run and one-off production parts. Nesting software on the other hand is ideal for mass production of parts with minimum waste. Techni’s machines are also capable of running without an operator present. This means large production runs can be set up on the machine and left without an operator to supervise while the machine produces the parts, often overnight and throughout the weekend. This is referred to as “Lights Out Cutting”.

what size of

Table Will I Need?

Our waterjet machines come in a range of sizes to help suit all types of businesses and applications. These are things such as material types, part sizes, part accuracy, production runs, & workshop size and staff availability. If you have the room, we always consider pointing our customers in the direction of owning larger machines with bigger bed sizes, so that they are not met with the limitations in the future if they ever have the need to cut parts that are bigger in size. We are also aware that space limitations can be a major factor to consider, so we also have smaller machines available.

Our smallest machine, known as the I35 – G2, is sized at 1770L X 2600W X 2050H mm and is great for smaller workshops and small precision parts and prototype parts. Whereas our largest machine being I1020 – G2 which is sized at 8000L X 4200W x 2000H mm is great for bigger workshops, large parts and high production applications.

What kind of

Pump Will My Waterjet Need?

There are a few different types of pumps for waterjet machines, so deciding which one can become quite overwhelming for first time buyers. Luckily for you, our team of engineers has designed pumps that perfectly fit our waterjet machines, to provide you with the ultimate performance when cutting while also saving you money. When looking for a pump for your waterjet machine, you want to ensure it is going to provide an output pressure that is extremely accurate and consistent. The reason these two factors are so important during the cutting process is because you want to eliminate all pressure spikes. If pressure spikes occur during the cutting process, it can cause inaccuracy to the cut and the overall finished product.
Our Quantum NXT pumps are engineered on the basis of eliminating pressure spikes and they are proven to be 60% more efficient than standard hydraulic intensifiers.

Pump Will My Waterjet Need?
Waterjet cutting comes with some features that are unique to this type of cutting process. Some of these features make it extremely attractive to workshops when compared to alternative methods of cutting. Here are some of the features to take into consideration before choosing to buy a Waterjet machine.

No Heat

The most distinct feature of a Waterjet cutting machine is that it does not use heat at any point throughout the cutting process. This means that materials are not affected by any heat zones, so they can’t undergo thermal distortion or have their material properties altered by heat. This also means that parts are often a finished product after they leave the waterjet bed.

Complex Shapes & Designs

Waterjets make a very narrow cut (kerf) and have very low cutting forces. This allows part designers to have more freedom when creating intricate parts that are impossible with other cutting methods.

Low Waste Volumes

The high accuracy that waterjet cutting provides, means complex contours and shapes can be achieved easily, lowering the probability of failed cuts and also lowers the probability of waste. This is a highly valuable feature of Waterjet cutting as it means expensive materials are less likely to be thrown out.

Ease of Use

Although waterjet cutting machines produce highly accurate and intricate parts, the ability to control a waterjet machine is very easy. Either programmed via the main control board, or via a remote desktop, the machine can be easily used by most staff within a typical workshop.

Environmental Factors Should I Consider?
Often with this type of machinery, it is good to consider the environmental impact of noise, fumes and dust emissions that may be experienced when cutting. Modern Waterjet machines like Techni’s, eliminate all three by cutting under water. Noise levels are reduced drastically, even to lower levels than most machine tools. Dust is captured within the waterbed and not sent into the atmosphere, and no fumes are generated from the machine as it uses an abrasive stream of water to cut through materials instead of heat.
The two waste streams that are generated via a waterjet are:

1

Excess water containing very small amounts of solid fines, which can be filtered if required by local regulation and then sent directly to a wastewater drain. Kerf material and garnet waste can be sent to a landfill.

2

If the material being cut is poisonous—lead or beryllium, for example—both waste streams must be cleaned to meet environmental regulations and the water may be recycled.

What kind of

Costs to Run and Maintain a Waterjet?

A number of factors need to be taken into account when calculating an accurate figure for the operating cost of an abrasive Waterjet cutting machine. These are factors such as; Utility costs (electricity and water), consumables (abrasive material, cutting head parts etc), operator time, programming time and maintenance costs.

A typical Waterjet machine will cost around $15 – $50 per hour to operate when all these factors are considered. Some of these factors are influenced by the speed you want to cut at and the thickness and hardness of the materials being cut.

These costs are minimised in a Techni Waterjet by; using the most efficient pump on the market, making programming quick and simple to minimise the programming time, allowing for lights out operation to minimise operator time, installing an Abrasive Removal System to automatically remove the abrasive from the tank, installing an efficient cutting head which minimises garnet use and maximises cutting speeds, and having a machine which is designed to deal with the very harsh Waterjet environment to minimise maintenance and maximise up time.
