It is my goal to finish up the linear encoder housing design for the
USdigital's linear encoders this week. I have the
design pretty well finished. I also have the G code written for the CNC
machining.
I also have run a few parts on my own machines but will have a friend that
has a small shop make the parts for me using my G code.
But one of the problems is that I have to drill 4 3/16D holes in the
1X2X1 end caps. Two of the holes are thru 1" alumunimun and 2 are thru 2"
aluminum.
My question is that it is easy to drill them with CNC using a canned drill
cycle with about 10 pecks per inch but it takes quite a while even under cnc
to drill the holes. This would increase the cost of the hardware kit
significantly. Here is the alternatives as I see them.
1. Go ahead and finish drilling the 4ea 3/16D holes and figure the cost
into the kit.
2. CNC centerdrill the 4 holes and let the customer pick up the centers (not
critical) and drill the holes using a drill press. this should not be a
difficult task provided the customer has either a drill press or a mill.
Any other ideas or comments on the above would be appreciated.
BTW the time needed for me to have them cnc drilled would increase the cost
of the end caps by 75%.
