Examples of Laser Cutting Projects In November December 6, 2018 GFLasers Blog 0 185 Share on twitter This photo shows 2.5mm thick cr4 mild steel which has been laser cut on our machine with the largest bed size, 4000 x 2000mm, at our main site. By laser cutting these parts with nitrogen gas we are able to supply them without the need to remove the oxide layer, which would be created on the cut edge when using oxygen gas, before any painting/coating of these parts. As these parts, once coated, would later be used on specific vehicles for the mounting of carrying systems, be they roof racks or top boxes, they are prone to all the delights that mother nature is able to throw at them. This image shows aluminium ‘braces’ which have been laser cut, using nitrogen gas on our TLC Cut 5 five axis machine with nitrogen gas. We process high volumes of these parts at regular intervals. These are free issued to us by our customer, as a first operation we laser cut the hole and trim the end as shown in the photograph. We then secure these in the same fixture but the other way round, to then repeat the same process at the other end with, instead of a round hole we add a slot. This image shows the first form of what will later become a section of a sunroof mechanism. These parts have been laser cut by ourselves on one of our flatbed laser cutting machines and then handed over to our sister company Moseley Brothers who, by using one of their vast selection of presses, achieved the illustrated form. Each part is ready to be split into two sections on our five axis 7040 machine before being handed back over to Moseley Brothers for re-striking into their final form. This image shows a batch of formed hollow section, which has been free issued to us by our customer. Each one of these sections is to be processed on our 7040 Trumpf five axis laser cutting machine to add all necessary holes/slots and end detail. Due to the high volume of these parts which we process on a regular basis, we utilise the production capability of the machine to ensure that any downtime is kept to an absolute minimum. Thus ensuring that we are able to provide fast turnarounds on the supply of these to the automotive sector. Within this pictorial you will see another regular batch of free issue formed parts which have been processed on our TLC cut 5. Five axis laser cutting machine. This 12 year old machine has served us well in oxygen laser cutting the mounting holes and trimming the excess material from the pressing process. As these parts are to be supplied to the automotive sector, batches are large in volume and regular in frequency. This image shows a batch of recently completed parts which we have processed for one of our largest customers. These 2mm thick mild steel parts have been laser cut on our L20 CO2 Trumpf machine using Nitrogen gas. The use of this gas results in there being no oxide layer on the cut edge as opposed to when cutting with oxygen. Each of the seven folds on each of these parts was done on our 100 tonne, HFEII Amada press brake. Our in house created program and bend sequence allows us to fold these parts completely, without needing to alter the tooling being used, or orientation part way through. This pictorial illustrates another batch completed of what has become a regular order for our five axis 7040 Trumpf laser machine. Each of the free issue lengths of box section, which is supplied to us at the final length, is processed on our own in house designed and manufactured fixture. This ensures that each and every section of what will be used in drywall systems is positioned with exactly the same datum point every time. Once positioned and fixed in place, we laser cut, with nitrogen gas, 4 large slots as well as removing material from one side to in essence, create a length of channel for use in new builds and refurbishments. This image shows a ‘nest’ of laser cut parts which were processed on our L50 fibre Trumpf laser machine. These mild steel parts, which were laser cut using nitrogen gas to allow increased adhesion of the final surface finish, will be removed from the machine bed to then proceed onto the next operation. Each part will be folded on one of our 3 Amada press brakes. Once these parts have received the appropriate surface finish they will be used within the automotive industry.
