Supreme Skills!Ultra Small Holes: EDM vs. Drilling
The challenge?
To make a hole lengthwise through a 0.5mm pencil lead that's 60mm long! Supreme Skills! contestants have never worked on such a small scale before! One contender operates a lathe to direct a tiny drill while relying solely on the feel of his control wheel. The other harnesses the awesome power of lighting through EDM (electrical discharge machining), which generates tens of thousands of tiny shocks per second. Both are consummate craftsmen who far surpass what experts believe to be possible. As their holes go deeper and deeper, unexpected problems arise. Are those sparks flying? How will these veteran machinists overcome these and other daunting obstacles?
Can they pull off a miracle?
