Wire EDM services
Wire EDM represents the most advanced technology for precise metal shaping using the phenomenon of electrical erosion. The process is characterized by the use of electric discharges to control material removal along a programmed trajectory. The technology enables achieving dimensional tolerances at the micrometer level while maintaining exceptional surface quality.
The WEDM system uses a thin wire electrode guided with micrometric precision between upper and lower guides. The wire moves in a controlled manner, generating electric pulses between itself and the workpiece. As a result of microscopic electric discharges, small amounts of material melt and evaporate, creating the desired shape.
Advanced applications of WEDM technology:
- Manufacturing precise industrial dies
- Production of injection mold components
- Shaping components with complex contours
- Machining materials with hardness up to 64 HRC
- Precise repairs and modifications of technological tools
The process does not exert mechanical forces on the workpiece, eliminating the risk of deformation and stress. The dielectric fluid provides electrical insulation, cooling of the machining zone, and removal of erosion products. Wire EDM allows machining of hard or delicate materials that could be damaged by conventional cutting methods.

FAQ: Questions and Answers
Modern CNC machining technologies make it possible to achieve exceptionally high dimensional accuracy. Standard tolerances for most CNC milling and turning operations are ±0.13 mm. The most advanced CNC machines can reach accuracy levels as fine as ±0.0025 mm—about one-quarter the thickness of a human hair.
Exact tolerances depend on the specific machining process. Three-axis and five-axis milling typically achieve ±0.13 mm, while grinding operations can deliver significantly finer results. The international ISO 2768 standard defines four tolerance classes: fine, medium, coarse, and very coarse. CNC Partner’s production process ensures compliance with the highest precision standards according to customer requirements.
CNC machining technologies offer exceptional versatility in terms of workable materials. The most commonly machined materials include various grades of steel, such as carbon steel, stainless steel, and alloy steels with different hardness levels.

Advanced CNC technologies allow for the machining of difficult-to-cut materials. Superalloys, titanium, and composites require specialized tools and cutting parameters. CNC Partner’s machines are equipped with modern control systems that optimize the machining process for each material type. Wire EDM enables the machining of materials with hardness up to 64 HRC, surpassing the limitations of conventional methods.
Selecting the right cutting tools is a key factor in successful CNC machining. Tool choice primarily depends on the type of material being machined. Hard materials require carbide or ceramic tools, while softer materials can be processed using high-speed steel tools. Tool geometry, the number of cutting edges, and rake angles directly influence machining quality.
Machining parameters include cutting speed, feed rate, and depth of cut, all tailored to the specific application. Tool coatings such as TiN or TiAlN enhance durability and reduce friction. Tool holder rigidity and machine stability prevent vibration, which affects surface finish. CNC Partner uses state-of-the-art cutting tools selected according to proven technological procedures.
Surface quality in CNC machining is defined by various roughness parameters. Standard surface roughness for basic milling and turning operations is Ra 3.2 μm. Precision grinding and polishing processes can achieve finishes of Ra 0.8 μm or better. Surfaces with a roughness of Ra 0.4 μm are considered mirror finishes.
Finish quality depends on several technological factors. Tool sharpness, cutting speed, feed rate, and type of coolant directly affect the resulting roughness. The finishing process can be optimized by adjusting machining parameters. CNC Partner offers a range of surface finishes tailored to industrial application requirements.
- Milling achieves Ra 1.6–6.3 μm, depending on cutting parameters
- CNC turning provides Ra 0.8–3.2 μm with proper tool selection
- CNC grinding delivers Ra 0.2–1.6 μm for precision applications
- Wire EDM typically results in Ra 1.0–2.5 μm
