Luoyang Xincheng got a new task on 7th, Nov., 2015. This time, we removed a drill (material:alloy and tungsten steel) out of a work piece weighted 2 tons in Luoyang Yiming Machine Manufactory.
If the drill is only made of tungsten, it could be scraped out easily. The hard problem is that the alloy part is also broken in.
The work piece is 28mm thick, the drill ofφ18.8 was broken in that through-hole.
So, we operated with High Power SFX4000B Broken Tap Remover and set the distance of processing. Finally the hole was processed through by an electrode of φ9. The broken drill pieces were knocked off after processing.
The latest updated SFX-4000B did this job perfectly. The shining touching panel and shake head make it easier to fulfill this task.
After a smooth processing, we found that the drill had already bonding with the work piece. Those pieces could not be tapped out at all.
So we broke the structure of drill by corrosion off the three edges.
All the broken drills were removed out. The machine tool could work again.
(During this High Power SFX-4000B Broken Tap Remover processing, the work liquid replaced tap water due to the cast iron material. )
