Geeky stuff , I know , but there are some very good engineers on this forum who might be as amazed as I was . It even works for drilling " off-axis " , and there is almost zero force on the cutting tool !! Have a look ..... what can't speak can't lie .... Drill through anything (conductive) with Electrical Discharge Machining
Great but not the sort of kit you will find in the average workshop, let alone garage. This technology has been around for decades, spark erosion and electric wire erosion. Both impressive to see. I have used water cut steel profiles in my course of work, A clean cut and no local heat problems at the site of the cut. Thickest cut was 150mm.
Not really drilling, it’s normally called “spark eroding” Been used by toolmakers for years, can also use cnc machined graphite electrodes to spark erode full 3D form cavities in injection mould tools. During my working career I’ve lost count of the number of plastic and die casting tools I’ve bought that have been manufactured with this process, millions of pounds worth on behalf of the companies I’ve worked for, it’s been interesting to say the least
I could actually do it with both eyes shut, and have in the past, I just give it to our tool room who have been using spark erosion since the early 1960's Correct again Chris, you are getting good
You might like a view of one of out 30 tonne core back twin shot £1,000,000 injection mould tools, fixed half with the back plate off
The hot runner system alone will be worth a fortune! If it’s a 2 shot, what kind of parts is it making? Thanks for that, I’ll be having nightmares tonight !!
