A Automatic Jack for Rotofit Driller

Su Solberg

HI everyone.
I am designing a system that can automatically drill holes on a concrete wall by a standard hand driller (just to drill 10mm holes with 100mm deep stroke). The automatic driller will be place at front of the hole before the drilling start by a steel frame.

My concept is 2 stage jacking.
1st stage, jack the drill to the surface of the wall
2nd stage, jack the drill into the wall with 100mm deep.

However, I found the following problem
1. heavy vibration due to hammering during drilling
2. step motor + roller chain / pneumatic is better

How I have to treat the special condition during design.

Thanks for you time and assistance.
