Tapping electrode is very important element to drill and tap for very hard metals, tight tolerance and high productivity demands.
Our tapping electrode is producted through special cutting-process for thread by CNC machine. The quality will be compared with a rolling system in straightness and tolerance of outer diameter.Our product always will be preserved the superior straigtness, pitch and outer diameter exactly. |
|
| |
|
|
| |
|
|
| |
a) Straightness : 97%
b) Tolerance of pitch, outer diameter and length : 0 ~ + 0.02mm
c) Material : Copper Tungsten, Copper graphite - EDM C3
d) Shape : With Flushing Hole, Without Flushing Hole
e) Process : Cutting thread system with single point tool by CNC M/C, not Rolling system |
