Why turncircuit

quality assured

We use modern machinery and a strenuous quality process to make sure that every part is machined precisely to your exacting specification.

fast turnaround

We understand that having an item in the right place at the right time is crucial to our customers workflow.

Flexible production quantity

Whether a large production batch or individual component order, our production volume is variable to suit your needs.

shipped worldwide

We manufacture in the UK and ship worldwide using an approved carrier to make sure that your order is delivered to you in a timely manner.

Manufacturing services

Turncircuit offer a complete custom machining solution from start to finish.

CAD design

We can work from your existing technical drawings or assist in producing machine ready diagrams.

Milling and turning

Our machines cover a range of sizes and machine to very high levels of accuracy, producing components in plastic, ferrous and non-ferrous materials. See our machining capability for more information.

3D printing

We are able to offer 3D printing for the development of prototypes and particular applications where traditional milling and turning don't suit.

Quality control

To maintain a high standard of quality, our inspection department is equipped with a CMM (Co-ordinate measuring Machine) to measure and record the features of the components produced. Whilst in production, continual monitoring of the key features are carried throughout the manufacturing process and recorded to assure consistency.

International delivery

Turncircuit is a global supplier of cost effective precision components utilising the minimum manufacturing operations to provide a quality, low cost part within a sustainable lead time.

Digital design

We operate two CAD/CAM systems to handle the programming, designing and engineering of our customers' components. (EDGECAM version 2015 R1, 3D CAD/CAM, Part modeler and ESprit 2014) These systems have the capability of handling 3D Solid Models, and can produce NC programs for our Mill/Turn Five Axis Lathe, Mill/Turn Centre, Vertical Machining Centres integrated with a 4th axis, and 3D printer. To handle the procurement of materials, customer orders, purchases, control of processes, planning, and invoicing we have in place a “MRP”system (REDant). The system has allowed us to consolidate and manage all aspects of our customers' orders with full traceability and full control.


Our factory is based near London in Sevenoaks, Kent in the South East of England, UK.

We supply products Worldwide.
