Waterjet cutting is an excellent way to profile cut all metals and their alloys and it is excellent for cutting titanium plate and titanium sheet metal.
We can work with Titanium in house and on this page we are showing a selection of parts produced for the national oceanographic centre for use on their drilling equipment that they specially designed to bore the 3km hole down through the ice at Lake Ellsworth in Antarctica.
Titanium was selected for some parts as it is stronger than steel and stainless steel, it has excellent corrosion resistance and is over half the weight which was very important with the high cost of transport to the remote location it had to travel.
The parts you see here were produced from various grades and thickness of titanium.
The circle on the top right was waterjet cut from 12mm thick grade 2 titanium plate, the holes were
de-burred and some of them tapped with metric threads, there is a steel 6” rule in the picture to give you a sense of scale.
The spanners you can see on the right were waterjet cut from 3mm thick grade 5 titanium plate to a tight tolerance and then final machined on a cnc milling machine for the mouth openings so they would fit with the required precision of the job. These spanners are to be used in an air sealed chamber and had to be very light but strong, you can see a penny in the picture to give you a sense of scale.
Along the bottom on the left and on the right are a selection of titanium parts waterjet cut from 20mm thick grade 2 titanium plate, there were to be final machined and used for clamping arms and locks in the drilling head and probe assembly.
Water jet cutting is an excellent way to profile titanium plate and sheet as it is a cold cutting erosion process, with no heat effected Zone this means the cuts are clean, the metal is left unchanged thermally and from us you get nice clean and crisp parts!
There were many aluminium parts produced for the drilling rig, probe and ancillary equipment, much of which was water jet cut from 12mm thick aluminium plate.
Shown on the left is one of the big aluminium discs water jet cut from from 12mm thick aluminium plate with some holes counter sunk and other holes machined to take stainless steel helicoil inserts. Stainless steel Helicoil inserts were used because it adds a hard wearing thread to the aluminium, if the aluminium was threaded on it’s own it would be easy to damage the threads in the harsh conditions and environment that this will be used in.
The other aluminium parts shown on this page were various discs and covers used on the drilling rig and probe All the aluminium parts produced were electroplated with a “sulphuric acid anodised” finish for industrial protection to the aluminium.
PVC Plastic parts:
We also water jet cut and machined quite a few parts in white PVC plastic for the probe preparation, the picture above on the left shows all the parts ready for assembly and on the right are the scientists and engineers in the laboratory assembling the probe, due to its long length and fragile nature, it was assembled and prepared on specially designed jig manufactured in PVC. We waterjet cut the parts from 12mm thick PVC sheet and machined them to the drawings supplied by the designers and engineers.
