FOCUS ON WATERJET
The Optima 420 with twin cutting heads.
that can only be cut with waterjet due to the strict limitations on heat transfer during processing. With the twin-head capability, we can cut double the number of parts that our competitors can achieve. This instantly makes us more cost-competitive with the bonus of significantly reduced lead times. Our turnaround times can be days, not weeks, especially on large parts.”

Referring to one large subsea pipe-cutting project, Peter Robinson added:“ We are currently profiling large nylon pipes, and these heavy-duty parts need a stable cutting environment. The machine has a robust steel frame that withstands excessive weight and vibration and accommodates all our large parts.”
Commenting upon the market benefits of the Optima 420, Robinson added:“ We are extremely competitive on both price and turnaround times due to the twin-head capability. We are even scheduling work to load the machine at the end of a shift to run lights-out. Depending upon the job, the machine will run for 10 to 20 hours unmanned, and the next step is to look into fitting cameras on the machine. This will help us to monitor, reload and run the Optima for even longer unmanned periods over evenings and weekends.”
Software streamlines throughput software on the Optima 420 has also made a significant impact on Waterjet-Tec.
Alluding to this, Terry Stewart confirmed:“ The IGEMS system is straightforward to use. It makes programming parts extremely fast and efficient, so we can create programs while the machine is running. For customers
The Optima 420
In addition to a sturdy base and frame design, the Optima 420 has a robust bridge design with twin-sided drives and digital AC servos on each axis.
“ This offers a rigid CNC platform for the 20m / min. rapid axes acceleration of the machine whilst dampening vibration and enhancing precision and surface edge quality. The Optima also has a precision 40mm diameter ballscrew drive that further underpins its precision and stability,” said Kerf.
Customisable bed sizes can fit a workshop layout and accuracy is cited at ± 0.1mm positioning with high-speed gantry movement. Highpressure pump options deliver up to 60,000 psi. The machine features advanced X, Y and Z axes with an optional five-axis head for bevel and 3D profiling. who supply drawings as. STEP and. IGES files, we can add toolpaths plus calculate machining times and turnaround quotes for customers in minutes. This gives us a massive advantage over competitors. Additionally, the nesting technology minimises material waste and costs whilst the speed and contours of cutting paths are also optimised to streamline production and minimise non-cutting times.
“ Like the availability of spares, consumables and any other support we need, Kerf is always available to help us with the software. However, the IGEMS suite is very intuitive and if we do have any challenges, it features a complete library of online video tutorials where we can upskill ourselves,” he continued.
Peter Robinson concluded:“ We are delighted with everything that Kerf has supplied. From the initial discussions to commissioning and ongoing support and consumables, Kerf has proved to be a partner on this journey and supported us at every step. As for the machine, we fully expect the Optima 420 to have a very short payback period. Our annual turnover will be approaching £ 1m in the near future, which is a fantastic foundation for a new business to grow …” n
