A Automatic Jack for Rotofit Driller

  1. Jan 12, 2010 #1
    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.
