Pneumatic vs Electrical screw drive | 18 October, 2002

Hi Experts,

Here in Box builds area, there was an argument on frequency of verifying torque reading. Shiftly changed to daily and now we are changing it to weekly. The reason for relaxing this frequency is b'cos the data we collected shown that the torque reading is pretty stable for the last 6 months and we don't see a need to do it too frequent. What is the best frequency for checking the screw driver torque ?

What is the different between pneumatic screw driver vs electrical driven ? What are their advantages ? Which one is more stable ? Why one is better than the other ?

We did weekly and monthly. Final assembly (Heavy use) recieved weekly. Field service area, sub assembly, low volume, ..... we went monthly.

I wrote the ISO specs to read "Calbration of screw drivers to be monitored and logged"( this Simplified of course)and we got it accepted trough or ISO paper trail.

we also used both Air and Electric and both worked fine. Theair was easy to adjust be cause it would just take a philips head to change. The electric ones were a lil more indepth as there were locking rings and so forth to get to to adjust.

The air hose and tool balancer is not fun to fart with but the air screw drivers worked great. Our big problem was the operators would shift things around dependingon what build was coming through.

We used a mountz torque meter for calibration and would send that out yearly for recal.

the only real issue we had was the electric drivers required a box that would sit on the bench taking up valuable space. Also, no matter how many electrical outlets there were we always seemed to need more.

Electric drivers are harder to adjust wich keeps production people from messing with 'em. Electrics are resistant to other variables such as air preassure, quality, other air supply users on the same line and so on. I prefered to use all electric except for the larger torqure values where air drivers excelled.
