NTG world-class precision engineering

NTG is trusted to deliver excellence by leading UK and international companies across a range of industries. With a selection of specialist services, their highly skilled team consistently deliver complex parts to an accuracy of 5 microns or better.

With quality as their priority, NTG give customers the reassurance that their components will be right first time, regardless of the complexity or function. Their dedicated inspection team verify every item using a 6-step assurance process. This covers a range of advanced inspection equipment, including multi-axis coordinate measuring machines (CMMs), optical projection, hardness testing and gauge calibration.

As one of only 10 UK businesses to be given World Class status by the GTMA, NTG also has ISO 9001, ISO 14001 and First Point Assessment (FPAL) accreditations.

NTG precision-engineering services

5-axis machining

Using the latest 5-axis CNC machining equipment and techniques, NTG’s team engineer precision components for high-stress environments and complex technical challenges.

Surface and cylindrical grinding – state-of-the-art CNC and manual

For projects with the tightest of tolerances and a precise surface finish. Up to 1.6 metres in length and 350 mm diameter, internal, external, out of round and thread grinding.

CNC milling

NTG’s CNC milling processes quickly produce prototypes and precision-engineer final parts.

CNC turning

Having invested strongly in their CNC precision-turning section, NTG can complete traditional 2-axis CNC turning. Their twin turret, twin spindle machining with live tooling is used for complex parts.

EDM wire and spark erosion

EDM allows precise machining of the hardest components and complex geometries. NTG’s team of experts work with clients to create the most precise components.

 Conventional milling and turning

Complementing their CNC machining services, NTG’s conventional milling and turning sections provide the perfect flexibility for a quick and simple solution.

CMM inspection

To achieve the highest standards of accuracy and precision, all NTG’s finely engineered components pass through a quality process using a coordinate measuring machine (CMM). This ensures clients receive a product that precisely matches their specification and requirements.

Processing and finishing

Complementing their precision machining, NTG provide a full range of post-processing and finishing services, including welding, surface treatments, heat treatment and material testing. These ensure the optimal performance of components suitable for all environments.
