Effects of speed/torque on longevity?

Hi,

I'll jump right to the point here,

Our robots are programmed to use a lot of very high speed moves, and little to no fly-by's (Zones of fine to 1 throughout). 

There is little precision required, they are essentially all pick and place type robots (i.e., move a part from a press, or pick from a conveyor, and put on a pallet or similar.)

The resulting operation is harsh.  Shaking, jerking, etc.  We do utilize a lot of older robots, purchased used, so many are compromised from the start- but we have a lot of issues with bad drives and motors. 

So my main question-

Do high speed starts/stops, and all around "rough" programming have as big of an effect on hardware and longevity of parts as I feel it does?

Thanks in advance

When the robot has the correct armloads and payloads set, it will figure out acceleration\deceleration such that it won't damage itself.  I have seen many jerky, shaky robots in the past and after correcting those programming deficiencies, saw much smoother motions.
