Mataco Wire Surface
Conventional Wire Surface
Coated Wire Features: 
No Acid-Corrosion and No Damage to Resins: The special treatment avoids acid-corrosion on machine and work piece. Filtered water and pH will not be damaged. Thus lengthens the life span of the ion resins.
High Surface Quality: The special treatment makes wire surface smooth, free from dirt, rust and grease that causes inefficient electric discharge.
Standard Weight Control: By perfect control in process, we obtain the standard weight per coil that enables us to maintain the processing time stability and the drawing accuracy, this ensures the stable quality EDM wire.
No Weldment: The rough surface caused by welding could affect the quality and accuracy of performance. The welded wire tends to break which results in lost time to re-thread.
High-Dimensional Precision: Due to the control system of diamond dies and lubricant, wire diameter tolerance and roundness tolerance are both limited to 1/µm. No scratch, cracking, twisting and deformation can be found on our wire.
Outstanding Straightness: The outstanding straightness and quality Zinc Coated wire ensures smooth automatic threading.
