Our reputation for quality, reliability, and technical excellence has been built on decades of expertise, advanced facilities, and industry-leading capabilities. From our base in Greater Manchester, we provide complete CNC machining services to customers in the North West and throughout the UK.
CNC Turning
CNC turning is a precision machining process where a cutting tool removes material from a rotating workpiece to create engineering components. Controlled by computer numerical control (CNC), it delivers high accuracy, repeatability, and efficiency. It is commonly used to manufacture shafts, pins, bushes, and complex engineering parts.
We specialise in precision manufacturing across an extensive selection of materials, including stainless steel, aluminium, mild steel, engineering plastics, brass, and bronze.
CNC Milling
CNC milling is a precision machining process where rotating cutting tools remove material from a fixed workpiece to create complex shapes and features. Controlled by computer numerical control (CNC), it enables high accuracy and repeatability. CNC milling produces components with slots, pockets, contours, and intricate three-dimensional geometries.

Strengthened by Heritage
In 2024, Sella-Askus Engineering Ltd became part of Sterling ITI, further strengthening our capabilities and expertise.Founded in 1978 by Peter Ratcliffe and Kieran Burgess in the cellar of a mill in Buxworth, Derbyshire, Sella-Askus was built on a simple philosophy:“Just ask us, and we will machine it for you.” This customer-first approach inspired the company’s name and established a reputation for versatility, craftsmanship, and dependable service that continues today as part of Sterling ITI.
CNC Machining FAQs
Sterling ITI provides a range of precision CNC machining services designed to produce high-accuracy components for industrial and engineering applications. Services include CNC milling, CNC turning, drilling and the manufacture of complex custom parts. Using advanced CNC equipment and skilled engineers, components can be produced to tight tolerances and consistent quality. Whether you require prototype development, small batch production or larger manufacturing runs, CNC machining ensures repeatable precision and reliable results.
CNC machining can be used to manufacture components from a wide variety of metals and engineering plastics. Common materials include aluminium, stainless steel, mild steel, brass and copper, as well as plastics such as nylon, acetal and other durable polymers. The choice of material depends on the mechanical strength, corrosion resistance and performance requirements of the finished component. CNC machining provides excellent accuracy across these materials, making it suitable for demanding engineering and industrial applications.
Yes, CNC machining is ideal for producing custom components, including one-off parts, prototypes and full production runs. Parts can be manufactured from customer-supplied drawings, CAD files or technical specifications to ensure they meet precise requirements. This flexibility allows engineers and designers to test prototypes before committing to larger manufacturing volumes. CNC machining also ensures consistent quality across repeat orders, making it suitable for both development projects and ongoing component supply.
