Machining

Once our design work is approved (or working to your supplied design documents), we undertake in-house machining to get your precision engineered product or component ready. From one-offs to prototypes to production runs, this is where we exercise our skill in precision engineering, honed from years of manufacturing industry-leading triple offset butterfly valves with Hobbs Valve and the Great British Valve Group.
We specialise in the machining of exotic materials such as super duplex, titanium, inconel alloys and aluminium bronze, with experience in all the challenges such materials are known to throw up. Our CNC program creation is done using SolidCAM software.
Our equipment and services include:

CNC turning / lathing (up to Ø800mm x 1000mm)

Computer numerical control (CNC) is the industry standard for precision lathe work and we have a pair of high-spec two axis high powered lathes capable of turning to incredibly high fidelities in line with the designs we programme in with SolidCAM. Our engineering experts know how to make the most of these excellent machines and you can rely on HPE for outstanding quality and accuracy.

5-axis CNC milling (up to 1120mm x 950mm)

5-axis milling refers to the use of milling machinery which is capable of moving in five different axes at the same time – x,y and z motion in addition to two additional rotary axes. This helps the cutting tool to approach the part in question from all directions and leads to unparalleled accuracy and precision of machining.

Water jet cutting (up to 3000mm x 2000mm)

Ideal due to its resistance to heat build-up, water jet cutting can be used for making precision cuts to a variety of materials, with incredible accuracy. Our cutter is made to handle high production rates for a range of versatile applications, and we’re delighted to add this new service to our range.

CFD

Computational Fluid Dynamics – a way of predicting the flow of a material or property within a substance or system, calculated by numerical analysis of key properties. It’s used in a variety of settings, in particular when predicting the behaviour of heat flow.
This system allows us to compare alternative designs or refine a selected design until we’re 100% confident of the performance of the finished product.
