The Subcon Show is Nearly Here

PRV Subcon imageWith only 12 days to Subcon at the NEC in Birmingham 2 – 4 June, PRV Engineering are gearing up for what we hope is another successful show. This will be PRVs 8th visit to the highly successful show which has improved and evolved over the years.

In its 32nd year, Subcon provides a meeting platform for buyers, specifiers and key decision makers from all industry sectors. It’s is a great place to meet, compare suppliers, discover and discuss new technologies and to forge new partnerships. Continue reading

Why Plate Copper Busbars?

PRV_Busbars_varBusbars made of copper are commonplace in the world of electrical power distribution. Switchgear, panel boards and busways all use busbars to convey substantial amounts of electricity, allowing more flexibility for circuits to branch off.

Copper is more resistant to rust and corrosion and so is commonly used in the production of busbars and other electrical equipment.

However, copper does oxidise over time and because of this the resistance in the conductive metal will increase, meaning that more power is needed to carry any current along its surface. Beyond a certain point, the metal can begin to flake and fall apart. It is for this reason that many metals are plated – it helps them retain their positive qualities and attributes.

New Train Carriage Design wins a Share of Funding

railway reacksBeing involved in the rail industry, we at PRV like to keep an eye on the latest developments and innovations coming over the horizon, whether it’s to do with passenger travel, the moving of freight or the development of the trains of the future. So the recent headline about a UK company winning funding to develop a solution for passenger travel and the movement of freight for the future caught our eye.

A St Ives based company has won a share of £2.2m through the Tomorrow’s Train Design Today (TTDT) programme.

Their train carriage design, where passenger carriages can be reconfigured to carry freight or passengers at different times, is one of 3 designs that won a share of the funds to develop the rolling stock of the future. Continue reading

What next for the auto industry?

auto industry care wireframeThe auto industry has come a long way since the introduction of the first car.

Electric and hybrid cars were once thought to be futuristic (along with flying cars). Now electric cars are on every forecourt of major showrooms across the country. Increasing numbers of super fast chargers are being put in place which means that electric and hybrid cars are able to travel much further than when first introduced. In many areas it now only takes 30 minutes to recharge a battery – just enough time to stretch your legs and get a cup of coffee, but a big enough charge to take you another 100 – 300 miles (depending on the model and make of your car).

5 Axis Machining in Modern Engineering

image of Mazak 5 axis machining equipmentWhen considering 5 axis machining, it is important to look at the differences between it, and the more common 3 axis cnc system. The most apparent is that a 5 axis system has the normal X, Y, and Z axis but can also rotate on it’s X and Y axis. This leads to a number of distinct benefits.

A major advantage of the 5 axis system is set up, as complex parts can be machined without having to re-set the work piece. This has the two fold effect of firstly, speeding up the machining process as the work piece does not need to be re-set; and secondly accuracy. The zero datum remains undisturbed during the process so reducing the likelihood of production tolerance errors.

Five axis machines can also utilise shorter, more rigid tooling, which is suitable for higher cutting speeds and lower vibration allowing more complex three dimensional profiles and deeper pockets to be cut without the need for a re-set, or a change of tooling. This again helps to ensure the accuracy of the finished part. Continue reading
