Waterjet cutting metals and it’s alloys:

Waterjet cutting is an excellent way to profile cut all Metals and their alloys, it is not just an alternative to laser, plasma or flame cutting but in our minds it is a better process altogether.

There is no heat effected zone (HAZ) common with the other cutting methods, there is little or no burr left on the cut part, there is no dross or dirty edges, the material is not effected or contaminated by the process.

The cut edges are clean and crisp, with a high degree of accuracy, and with our dynamic head connected to our machine we can offer straighter and more accurate cuts in thicker materials.

On this page we have selected some parts and projects cut to demonstrate the benefits of the process of waterjet cutting and waterjet profiling of Metals and their alloys.

We can cut: Aluminium, Stainless steel, Mild Steel, Copper, Brass, Titanium, Hardox, Armox 500T, Tantalum, Tool Steels, Hardened Steels, Armour Plating, Spring Steel, Duplex, Ground Flat Stock, Cast iron

Titianium and inconel fused together into a plate then waterjet cut by us into small billits

Titanium & Inconel...

We waterjet cut these for a customer , the material came to us as a 23mm thick plate pre-made with the Titanium and inconel attached / fused  together, we waterjet cut 19 mm and 16mm diameter billets from it ready for machining on a lathe.

detail waterjet cut into spring steel pre machined billets

Special Spring Materials...

We get a lot of pre-machined parts come to us to have features waterjet cut in them, these discs were pre-machined into a  special spring steel. We designed and produced a special jig to hold the parts then waterjet cut the features you see here into the discs.

Our client chose waterjet for that part because laser and wire erosion both leave a recast layer, which nobbles the fatigue properties.

This again Demonstrates that the cold cutting process of watetjet cutting has many benefits over other cutting processes like laser or EDM cutting and profiling.

White metal bearing sections waterjet cutpropeller shaft white metal bearing sections waterjet cut ready for analysis White Metal Bearing Tests...

This is part of a large White metal bearing from a Ships Propeller shaft, the bearing has failed a few times and has gone for tests, we chopped up the bearing into specific cut shapes for testing purposes.

Waterjet cutting is a good clean method of cutting and is probably the only method of non destructive cutting of material for this purpose, any heat put into this job would of not only of effected the test results but would of also turned the white metal into it’s liquid state as it has a very low melting point.

Special & Exotic Metals / Alloys

Fixing plate waterjet cut from 10mm thick steel plate...

With the ability to cut virtually any 2 dimensional shape into virtually any material, waterjet profiling opens up great potential with our designs. This is a foot plate to a railing system we designed for a church, waterjet cut from 10mm steel plate. We designed this to be in keeping with other features within the church by taking photos from the surrounding area we were able to pick out a design that was in-keeping with the final location or the railing system we were producing.

Kamal house name water jet profiled from 5mm thick steel plate

Kamal house name water jet profiled from 5mm thick steel plate...

Kamal was water jet profiled from steel plate 5mm thick, we welded some studs on the back for fixings, then painted in a slate grey.

It was chemically fixed into the wall on 3 studs for a strong and hidden / minimal fixings.

Steel can be cut into very intricate designs and due to the cold cutting process of water jet the is no heat affected zone, no dross or burrs similar to those from laser cutting processes.

a small detailed water jet profile of a bike cut from 5mm thick steel plate

A small detailed water jet profile of a bike water jet cut from 5mm thick steel plate...

This bike was water jet cut from 5 mm thick steel plate. Using our abrasive water jet which is a cold cutting process with no heat affected zone we can cut very clean and sharp detail in materials like steel plate, this has many advantages over laser cutting as the cut edges has no contaminates from the process and the properties of the metal are unchanged, this makes abrasive water jet cutting an excellent alternative to laser profiling and in a lot of cases a far superior option

accurite detailed cutting in 40mm thick steel plate

Custom V block tool holder...

This Custom made V block was required for some tooling on our milling machine for a machining project. We had to hold our parts at the right angle for machining. This Was waterjet cut from 30mm steel plate for the purpose.

A vintage car renovation part waterjet cut from 40mm steel plate

Steel part for a pre-1930 car restoration project...

We were given a hand sketch of this shape and we were asked to profile it from 40mm thick steel, This is to be used in a pre-1930’s Car restoration project and would of originally been forged but unfortunately this is no longer possible, but by having the main body water jet cut from thick steel plate, it can then be turned, machined and ground to final shape and dimensions, and due to the process the edges are as the original material specification, there are not heat effects creating issues for further processing.                                               

Steel finger plate combs for water treatment plants

Steel Finger Plates / combs for liquid treatment plants...

We have produced these in various forms and waterjet cutting is the answer when cutting items like this, when these are profiled with laser or plasma cutting the heat causes distortion in the thin finger sections but also the heat changes the characteristics of the steel which means they don’t last very long.

With waterjet cutting there is no Heat affected zone (HAZ) and the material is unaffected by the process, we can also cut very hard steels, pre-hardened steels or stainless steels if required giving longer lasting and more accurate finger blade scrapers and combs. We also machined the stepped mounting faces on our cnc milling machine.                                               

A 4ft diameter steel cog drive wheel jet cut from steel plateLarge drive wheel water jet cut from 8mm thick steel plateLarge Steel Drive Gear...

The gear drive cog shown here was waterjet cut from 8mm steel plate, it is approximately 1200mm diameter and the drive wheel was slightly smaller in diameter. We were only given the old original parts to work from, there were no drawings or cad files and we had to work out the dimensions, gear teeth details and pitch from the old worn parts. This was no problem for us with our engineering abilities.

Steel Clamp Mechanism...

We designed this small steel clamp mechanism for a customer, it was waterjet cut from 12mm steel plate and then machined by us to get the final hinge parts fitting properly, it is approximately 100mm wide overall.                                             

ready for tensile stress testing steel plates cut

Test cuts in Structural Steel Samples...

We were given a few structural steel sections to cut various test parts and samples from for scientific and structural testing.

Waterjet cutting was the perfect solution as the waterjet process doesn’t affect the structure of the metal in anyway which minimises false readings and bad test results.

Some of the parts were cut into “dumbbell parts” these are shaped to fit into a special machine that tests the strain of the material.


A round steel bar split down the centre with our waterjet cutter

Round steel bar split in half...

Our customer required some half round D shaped steel bars for a restoration project, these would of originally been forged. We water jet cut down the length of the round steel bar splitting it in two.This gives the required results leaving a clean face where we water jet cut.

A burger press form tool water jet cut from 30mm thick aluminium...

Using aluminium plate 30mm thick, this part was designed for a burger press. We offered the ability to have the tools split in two so the pressed burgers could be removed easily, by drawing the outer profile in Cad with some thought we created small handles to assist in the separation of the halves. We cut the inside edges at a much slower speed to keep them as smooth as possible for the casting surface.

custom made aluminium tripod brackets designed and waterjet cut and fabricated by safire

Products designed by us and waterjet cut in 10mm thick aluminium plate...

We designed these special clamps to mount fall arrest tripods used in the petroleum industry to fit on other equipment to make them easy to store and transport. We waterjet cut the designs from 10mm aluminium plate, which gave us nice burr free parts that needed minimal finishing. We then machined, fabricated and finished them .


these ship drain covers were waterjet profiled from 10mm thick brass plate

These ship drain covers were waterjet profiled from 10mm thick brass plate...

We cut a batch of drain covers to be fitted on a ship. Cut from 10mm thick brass the water jet profiling process is ideal, with no heat affected zone the finish is very clean and precise. The parts then had chamfers machined on the edge and the 3 holes were countersunk. Brass can be difficult to process by other profiling methods due to heat issues and if it is polished then the reflectiveness is also problematic, however with waterjet the cutting process is clean and simple leaving a nice finish.

a selection of parts nested into 10mm thick brass plate

A selection of parts nested into 10mm thick brass plate...

With our powerful nesting software, we can nest our parts in a multitude of ways including nesting inside parts. We can apply special technology to tag parts in, bridge parts together, group parts, apply common line cutting to assist in the best use of machine time and movement and a host of other special features.

When cutting expensive materials then it is important to get the best yield from the materials reducing scrap and wastage.

thin brass sheet waterjet cut into intricate designed parts

A selection of parts waterjet cut from 1mm and 1.5mm brass sheet...

With waterjet cutting at very high pressures it can be difficult to cut small parts due to the turbulence of the water and the energy created, however we are able to think outside the box and can cut small intricate parts, show here a selection cut in brass sheet. With a clean cut edge and a virtually burr free cut we can create very nice brass parts.


copper engine gaskets water jet cutCopper Gaskets, Copper electrical connectors and copper shims water jet cut...

We cut many parts in copper as water jet cutting  is really the only accurate process cable of producing intricate cuts in copper, processes like laser cutting are hindered as copper is a good heat conductor & quite often very  reflective which cause a lot of problems in cutting copper, with water jet cutting copper is cut cleanly and accurately &  we can cut from very thin parts like the 0.1mm thick shims shown here to thick electrical connectors and copper engine gasketsvery thin copper shims waterjet cutcopper electrical conectors water jet cut


Bronze can also be water jet cut...

We have cut parts in bronze materials and the clean cutting process is excellent or this purpose, shown here is a bronze sheet 2mm thick, we were given a picture of some calligraphy text to be cut from the centre of the supplied sheet and we turned this into a cad file ready for cutting on our waterjet machine, this was for part of a bronze sculpture, there is three bits of tape in the picture on the bronze these are holding some small parts that are the centres of some of the text.

aluminium extrusion proto type design 19mm thick aluminium extrusion design proto type 30mm thick

Detailed and accurate proto-type parts waterjet cut in thick aluminium plate...

We assisted our customer with the design development for these proto-type parts by giving them some idea of how to go about the problem they were trying to solve, Once they got their head around the solution we offered they then came up with the 3d designed parts. These are proto-type extruded aluminium parts that will be used in the marquee business for fold down marquee frames. They have been designed to end up being made by the aluminium extrusion process and will be extruded in long lengths then cut from the long extruded lengths into the finish parts at 19mm thick and 30mm thick extruded aluminium parts, however the extruded aluminium tools that are required to produce the extruded aluminium parts aren't a low cost item and the amount of extruded aluminium for the minimum order makes many thousand parts, so by coming to us for the initial trials and proto-types to be waterjet cut, the extrusions can be tried and tested at a much lower risk and cost to our customer. They then have the ability to try out their full design and show their customers a full working model made to high standards which enables them to get orders for their products before they commit themselves to the bulk purchase of the extruded parts.

The two parts here are shown next to a penny to give you a sense of scale, the part on the left is waterjet cut from 19mm thick aluminium plate and the part on the right was waterjet cut from 30mm thick aluminium plate. You can see the detail, the wall thickness of the parts was around 1mm thick on some samples we produced for trials and on these parts shown above the wall thickness of the part was around 1.5mm thick.

We can offer very detailed and accurate parts cut on our waterjet machine for your proto-types and end finished products but also as we are engineers we can assist in the design and development of your products. Please contact us with your project details

Round Stainless steel bar split into quadrants...

The picture above and on the left show a 25mm diameter round stainless steel bar split by our waterjet cutting into 4 quadrants.

This bar was 1200mm long and we cut it right down the length to split it into half's making D shaped stainless steel bar, we then waterjet cut the D shaped bar into half again creating  the stainless steel quadrant beading.

This has many uses either as beading on metal fabrication projects or as a finishing beading bar to be used on kitchen or bath room work tops.

We can offer a satin brush finish, or a polish finish if required making these perfect for your finishing requirements in and around your home, caravan or boat etc...

By using our water jet to cut these quadrants we can produce a nice clean cut that you can then use in your projects.
See a case study on stainless steel quadrants here:
