Laser, plasma or waterjet cutting?

laser, lasma and waterjet cutting machinesWhen you work in manufacturing you have a decision to make; laser, plasma or waterjet cutting? ‘Which one is best?’ is the first question that many people ask. The most up to date and technologically advanced must be the best, surely? Well that’s not the case. In fact there could be a case for using any or all 3 of the manufacturing processes depending upon your needs and what you value most from the machine.

Each has its own advantages and disadvantages, from speed to cost and even waste. So let’s take a look at each option. Continue reading

The versatility of waterjet cutting

waterjet cutting in acitonWaterjet cutting has really come to the forefront of manufacturing in recent years because of its versatility. There are an array of reasons to choose waterjet cutting over other methods, and they aren’t all about the actual cutting control. Improved efficiency in processes and reduced wastage and costs also factor highly, which by default leads to improved customer service.

Omni directional cutting, cutting widths, stress free cutting and improved finishing are all advantages of using water instead of more traditional cutting methods. However, one of the most fundamental things with waterjet cutting is that when you use water, there is no Heat Affected Zone (HAZ). This is the area around where you’re machining that gets hot because of the machining process. The heat generated in this area means the structure of the material gets altered and can be liable to fracture. If machining composite materials using traditional methods, the HAZ can cause all sorts of distortions and reactions, resulting in breakage and wastage. The ability to cut cold removes all these barriers and means that almost any material can now be cut with no alteration to its base structure. Continue reading

The advantages of waterjet cutting

waterjet cutting machineThere are many advantages of waterjet cutting compared to other methods, but if we had to try and summarise them neatly into a few words we’d say;

The ability to cold cut almost any material in any direction with less waste and a superior finish.

But really that’s not enough of an explanation, so let’s expand a little on that statement and address some of the areas of improvement over more traditional cutting methods.

Omni-directional cutting
Waterjet cutting allows omni-directional cutting – the ability to cut in any direction which gives much greater cutting flexibility. In most cases starting holes are not required as the water jet is able to perforate the material. It is now much easier to cut more complex shapes and designs into all sorts of materials.

PRV Engineering take delivery of Hydro-Abrasive Waterjet Cutting System

waterjet cutting systemAfter a busy few days at the Subcon Show in Birmingham, it was all hands on deck to take delivery of our new Idroline S1730 Hydro-Abrasive Waterjet Cutting System from Selmach Machinery.

The system is the latest addition to our suite of state of the art CNC Multi Axis / Multi Discipline machining centres and will allow us to continue to improve and provide the best service possible to our clients.

The Idroline S1730 hydro-abrasive waterjet cutting system is an elite design which ensures superior technological and productive performance. It uses a very high pressure jet of water or a mix of water and abrasive to cut a wide variety of materials and allows greater control and precision when materials being cut are sensitive to high temperatures.
