CNC Turning

Wye Valley Services specialise in high volume CNC mill-turn services to the UK market in metal and plastic upto 51mmØ. Below is an overview of some of the elements and specialties of the services offered.

Multi-Axis Sliding Head Machining

Our multi-axis sliding head machines are sophisticated enough to produce close tolerance high precision complex milled & turned components in a single hit. Combined with long, bar feeding magazines, this means we are capable of supplying high volume mill/turned parts quickly.

Fixed Head CNC Turning

We offer fixed head cnc turning for components up to 51mmØ. The fixed head offers a larger bar capacity, a faster cycle time and mill-turn capability.

Materials

We will turn almost any material you require. Much of our work is in mild steel, stainless steel and aluminium, but we also cater for more exotic materials including plastics and composites. Below is a list detailing the main materials that we work with:

Aluminium	HE30, HE15, 2011T3, Aluminium Bronze CA104
Copper	C101, Teryllium C109
Brass	Leaded Brass CZ121, Riviting Brass CZ131
Bronze	Sintered Bronze, Phospor Bronze PB102, PB1, LB4
Plastics	Nylon 6, 66, Perspex, PTFE, Glass Filled PTFE, Polypropylene, Acetal
Sintered Materials	Bronze, Alloys
Super Alloys	Titanium, Inconel, Nilo
Steel	220M07, 212M36, 210M15, 605M36
Stainless Steel	316, 303, 304, 430, 321, 416

Tooling

We use the very best lathe tools from manufactures such as Dormer, Seco and Iscar as well as the tool manufacturers detailed below:

CNC Milling

We carry out CNC milling to specification on turned parts in one hit. Milling services appllicable to our turning services include slotting, edge rounding, slopes, thread milling and facing.

Small Components

We undertake the cnc turning of microscopic components, typically with diameters of 0.5mm and up with milled features as thin as 0.1mm. Turning of microscopic parts using CNC bar fed machines allows for very high volume production capacities of as many as a million or more. Much of our work is sub-10mm, in particular our work in the telecom's, communications, and electronics sectors. We work towards the highest possible quality in everything we do, aiming for production runs with zero defect and customer satisfaction..

Small Hole

A combination of the best tooling and cnc lathes allows us to carry out reliable and repetitive machining of small holes up to (0.2mm Ø in stainless steel) six diameters deep in all materials. Feel free to call if you have a component that requires a small hole and we'll be happy to help.

Thread Cutting

We offer specialist internal & external thread cutting to suit your requirements including left and right hand, multi start threads using radial, flank and modifiedflank techniques where required. We can thread as small as 1mm x 0.2 pitch, tap short and long blind holes as well as carry out deep tapping with rigid tapping and pecking to achieve this.

Boring

We carry out secondary boring on drilled holes to ensure concentricity and fine precision as well as bore internal diameters not easily achievable with regular drill sizes. We bore all kinds of internal steps, grooves, undercuts, ridges and gradients to customer specifications.

Broaching

We carry out hexagonal, square, triangular and torx broaching as well as specialist broaching of asymmetric shapes and slots to customer specifications. We can also machine keyways and splines using both single and multi point full form cutters.

Knurling

We have a wide range of pressure and cut knurling tools for straight, diagonal or diamond patterns in soft and hard materials on components as small as 2mmØ.

Tube Work

We can also turn circular, square and hexagonal tubes upto 51mmØ in a range of materials which can offer a significant cost saving when compared to turning certain items from bar.

Quality

Certificates of conformity, inspection reports and material certificates can be supplied on request.
