HMW Machining VW heads using the Bridgeport EZ Trax

In this video, I use the Bridgeport EZ trax to interpolate the combustion chambers for larger pistons. This was my first attempt at filming anything, it has been on my go pro for some time so I hope someone gets a laugh from it.
I could have set up a fly cutter and plunged them to size but I find this way much easier as I always have a sharp end mill loaded.
I used the "do event" function where I entered a start point x0 y0 and then enter a cutter diameter, hole radius, lead in, finish amount and a feed rate, the machine does the 2 axis movement. As the operator, you just set the Z depth and spindle speed.
Thanks for watching

Hey Jeff ( I finally know your name 👍) The good part about going back and watching the earlier videos on a KZbin channel is you can see the raw videos. Where the people posting are still finding their way and usually nothing is scripted or pre-prepared. When I first had thoughts about starting my own shop a Mill pretty much like yours was on my list. The brands were a little different but the functionality was pretty much the same. The Manual Mill I currently own, was also something I was thinking about ?? The NC version gave me options that could definitely come in handy. But, the NC Mill was a little lighter on for other uses ?? The NC Mill was a lighter weight machine with less Travels in all Axis ?? It took some time to come to terms with which might be best for me ?? At that time I was mostly a Repair Shop with some Manufacturing. In the end I finished up deciding to go with the larger Manual Mill. But, when some of the Manufacturing jobs came in ??? I was kicking myself for not buy the NC version. That always happens with any machine purchase. You get something and lose something else at the same time. Thankfully, shortly after buying the Manual Mill I could justify a VMC. Wouldn't it be great IF you buy all the machines you needed at the same time. I guess, IF that was a reality. I'm sure I could justify doing something else with that much money 🙂👍

A manual mill might be handy

Fancy machining there. - a Wohlhaupter boring head would have been faster and much better finish.

cant fit one in the ez track it has a guick change 30 spindle, this is the way I have to do it because of z limitations, now if I ever get a riser block I will do it with a boring head. a good side wall finish is not needed, just a nice finish on the sealing surface. thanks for the reply!

It's actual .03936

It's actually 0.03937007874015748031496062992126. It is better to divide by 25.4 for unit conversion from millimeter to inch. Using 25.4 has no rounding error.
