Waveney Precision Ltd is one of the few specialist precision engineering companies that combine the plant and expertise to provide both EDM wire and EDM sinking capabilities.
"No job is too large or too small". We can machine components up to a weight of 2 tonnes, either as one-offs or in batches.
Controlled on 5 axis, wire EDM technology enables the economic production of complex forms that cannot conventionally be produced in a single piece. As a non-contact process, no stress is placed on the component, enabling high tolerances to be achieved, avoiding distortion and leaving a surface that requires minimal additional finishing
The Advantages of EDM Wire
The Machining of Complex Geometric Forms
Complex, contoured shapes can be produced in one piece rather than several, in the exact configuration that is required.
The Rapid, Economic Production of Prototypes and Low Run Parts
The ability to accurately machine complex designs, can eliminate or reduce fixture and tooling costs for one of a kind or low run production parts.
Formed through the wire EDM process, parts can be immediately used in assembly, with little or no additional finishing.
Precise Machining of Pre-hardened Materials
Because hardened materials can be EDM eroded, the need for the heat treatment of machined parts is eliminated, avoiding potential distortion.
Machining to Tight Tolerances, Avoiding Distortion and Stress
Very low machining forces allow tight tolerances of up to 2 microns to be achieved. With little or no stress imparted into the work only light clamping is necessary. Thin materials can also be machined without distortion.
The Accurate and Economic Machining of Exotic Materials
Exotic materials including A-286 Superalloys, medical grade stainless, titanium, Hastelloy, tungsten carbide, molybdenum, aluminium alloys and copper can all be machined. Better utilisation of valuable materials is provided through chipless machining.
Absolute Consistency Between Machined Parts.
Because with wire EDM there is no contact between the cutting wire and the surface, there is no tooling wear and absolute consistency can be achieved on every machined part.
Other EDM Applications
Templates and Profile Gauges
EDM wire erosion processes are highly suited for machining templates for copy lathes and profile grinding and for producing product inspection gauges.
Working in copper, graphite and copper-tungsten alloy, we have the capability to produce electrodes in complicated shapes, which are difficult to make by conventional methods.
Wire EDM cutting is a highly efficient method of accurately producing prototype parts, making the trial stamping of parts whose final shape is not yet determined unnecessary.
Very thin parts which are difficult to blank on a press can be produced in quantities of over 10 to a few hundred when stock sheets stacked together are machined.
Other Special Machining
Operating with a wire electrode as fine as 0.1mm diameter, we can provide a radius of 0.05 mm, reducing many man-hours in machining work.
The machining of extremely accurate holes in hardened plates and the machining of geometrically undefined shapes such as cams, gears, splines and free curves are also effectively achieved
