How precise is precision wire cutting?

Precision Wire cutting processing is an extremely precise method of machining.  Wire cutting, also known as CNC EDM cutting, is developed based on the principles of EDM perforation and forming.  Its working principle involves using a continuously moving metal wire (such as molybdenum wire, copper wire, or alloy wire) as the electrode wire to erode the metal through pulse discharge between the electrode wire and the workpiece, thus forming a cutting slit and achieving the machining of parts.

 

Unlike traditional machining techniques that require mechanical force and energy for cutting, wire cutting primarily utilizes electrical energy to process materials.  Therefore, wire cutting is not limited by material properties and can process materials of any hardness, strength, and brittleness, making it an important technique in mechanical machining.

 

Precision wire cutting has the following main characteristics: firstly, there is no significant mechanical cutting force during the machining process.  As long as the material is conductive or semiconductive, regardless of its hardness, rigidity, toughness, or brittleness, it can be processed.  Secondly, precision wire cutting can process parts with intricate holes, narrow slits, and complex shapes, with slit widths as narrow as 0.005 millimeters.  Additionally, it only processes the material along its contour, resulting in high material utilization and effective savings of valuable materials.  Lastly, precision wire cutting has high machining accuracy and is particularly suitable for small batch, complex-shaped, single-piece, or sample processing.

 

Precision wire cutting can process a wide range of materials, including conductive or semiconductive materials such as ordinary metals, high-hardness alloys, synthetic diamonds, conductive ceramics, ferrite materials, and more.

Precision wire cutting precision

	Wire speed	Machining accuracy	Surface roughness
Fast wire	8-10m/s	0.01-0.02mm	<2.5μm
Medium wire	1-3m/s	0.005mm	<1.3μm
Slow wire	<0.2m/s	0.001-0.002mm	<0.3μm

Through the above introduction, we can see that Wire EDM Machining has the advantages of high precision, wide applicability, and high efficiency.  It plays a significant role in modern manufacturing and provides high-quality parts and components for various industries.
