History of Waterjet cutting

Waterjet cutting is often used during the fabrication process of machine parts. A waterjet cutter, also known as a waterjet, is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet or stream of water. A mixture of water and an abrasive substance is also used in many applications.

Early waterjet machines could only cut softer materials as they had low pressure and could not handle harder materials and metals. They added an abrasive to the waterjet cutting nozzle in an attempt

PRV will be at Subcon Birmingham NEC

On Tuesday 6th of June, the Subcon show for 2017 kicks off at the Birmingham NEC. Subcon is the UK’s premier subcontract manufacturing supply chain show and this year is not to be missed. The Subcon show will run alongside the Advanced Manufacturing and The Engineer Design & Innovation Show. The show is until 8 June so you have plenty of time to rub shoulders with the best of the best.

Military Technology: Applications of Autonomous Systems

Whether it’s conspiracy theories, Hollywood or reality; there’s certainly no shortage of newsworthy mentions of new military technology being developed. Autonomous systems, for example, is vital to solve many of the most difficult problems we currently face. These include exploring uncharted oceans, deep space, providing aid in emergency situations and probably more applications in the defense industry.

Already we have Apple’s Siri, Amazon’s Alexa and Microsoft with Cortana. These systems all operate on autonomous technology and the demand

What is Shot Blasting?

Shot blasting can be described as a method used to clean, strengthen or polish metal surfaces getting it ready for the application of overlays or coatings. Industries using this method include automotive, aerospace, construction, rail and ship building among others. It removes rust or old layers of paint which is important when preparing surfaces for further processing like paint application, powder coating and welding work.

Waterjet cutting is one of the most effective methods of machining materials. With no heat affected zone, small cutting widths and omni directional cutting, virtually any material can be cut with precision and accuracy. Because of this, waterjet cutting results in better product finish with little or no secondary processing needed. In addition, waterjet cutting is more environmentally friendly as the dust, chippings or gas produced by other cutting methods does not occur. In addition, as there is no need to change tool heads, blades or lubricants for each material, machining time is also reduced.

Plastic, rubber, wood, glass, metals and composite materials can all be cut using a pure waterjet or hydro abrasive waterjet cutting. For some materials the addition of an abrasive agent is needed to aid effective cutting. Below is an overview of the types of materials that can be cut.

PRV Engineering Elaborates On The Latest Machinery To Be Installed

At the start of the year, we reported that once again PRV Engineering had invested in new machinery. The latest addition is the large format machining equipment and we thought we’d tell you a little about why we chose the equipment we did.

First and foremost, the reason behind our continued investment in staff, premises and equipment is our desire to provide the best service possible to our customers. Quality is top of our agenda and that means both in terms of the product produced and the service provided – they go hand in hand.

Investment in equipment and staff is extremely high on the list of priorities for PRV Engineering. Quality and customer service excellence are 2 of the most important things for the company and to provide those things equipment and staff need to be of the highest level.

In 2016 more new machinery has been installed at PRV Engineering and staff have completed training so they are fully up to speed on the operation and capabilities of each machine.

Hydro-abrasive waterjet machinery along with large format machining equipment were the latest additions to the workshop floor.

When we say the beauty of waterjet cutting, we don’t just mean it’s a great, effective cutting process – we do actually mean the beauty that can be created with a waterjet. It’s a highly versatile cutting method that produces much less waste than other forms of cutting, which in turn allows for more diverse design. The ability to cut more intricate designs and patterns allows for more artistic license to be given to designers. More complex, artistic design often leads to a more beautiful end product.

So, we genuinely mean beauty in more than one sense.

The ability to cold cut means that almost any material can be cut without the adverse impact of heat; there is no heat affected zone. Multiple small cuts, swirls and channels can be made without the material bending, warping, burning or having any sort of reaction.
In addition to having no heat affected zone, what else makes waterjet cutting so versatile and effective in creating complex and diverse patterns and designs?

There are few products that we use in everyday life that have not had CNC machining take some part in their production. Cars, planes, household machines and appliances, medical parts and toys all get to visit the CNC machine at some point in their production.
CNC or Computer Numerically Controlled machining has become more versatile then ever over the years. The number of axis has increased and the types of machine available now mean that increasingly smaller and more intricate parts can be manufactured using CNC machining.

Even though waterjet cutting has only come into its own in recent years it may surprise you to know that it has been around since the 1930s. At that time it was used at a low pressure and only for cutting soft materials. Whilst things continued to develop after the war, waterjet cutting became much more effective in the 1970s, when the first reliable high pressure pump was developed.

Whilst the earlier waterjet machines could cut softer materials they could not handle harder materials and metals. The ability to cut harder materials like metal came about following the addition of an abrasive to the waterjet cutting nozzle. This was a technique first used in the 1930s, however early versions of the nozzle were not commercially viable. Further development of the nozzle and the availability of a reliable pump led to a more effective waterjet that could now cut through a bigger variety of materials.
