hello ,
I am trying to make my first plastic injection mould, As there is no mold base supplier in my area, I need to make it myself, I just ended facing and squaring the edge of the plate, I am heading to drill guide holes in A and B plate.
the guide bushing/Pin are 25mm, so the holes need to be 25H7 , my concern is how to drill this four holes in an accurate way so it will match.
I am planning to spot drill with 6mm short lenght carbide drill ( I already have is in ATC , and no spot drill in the market ) , than drill 24mm using Morse taper HSS drill , follow by a 24.5 HSS drill, chamfer the edges, go throw with a 25H7 Reamer. Do you think this is a good way to do it ?
and with this approach would the holes match in both plates A and B. or should I drill the two plate together at the same time.
My machine is a leadwell V32i with a 14.7HP spindle.
thank you all
