<span style="">Hello All,<br>
<br>
Long time stalker, first time talker.<br>
As the title suggests, I'd like to hear some collective thoughts and experiences on expected equipment lifetimes.<br>
Obviously very dependent on what it is, what it does, who made it, who uses it, etc., etc. but in a very general sense when is the average piece of equipment (if there is such a thing) on borrowed time? I'm sure we all have some decades old machines and that
replacing them solely for modernization's sake would be considered financial malfeasance. However, under a more manufacturing mindset a strategy for planned obsolescence is not a bad idea.<br>
<br>
To hopefully facilitate some replies/debate/conversation, here's my two cents:<br>
<br>
Metrology Equipment --> 5-10 years<br>
Processing Equipment --> 12-17 years<br>
<br>
Also took a quick age survey of our ~50 pieces of equipment and found the following distribution:<br>
<br>
<span style=""><img id="Picture_x0020_2" width="310" height="195" border="0" data-outlook-trace="F:1|T:1" src="cid:image001.png@01D8B3C7.1DF8AD50"></span><br>
<br>
If the pie chart graphic isn't visible: 0 tools < 5years, 15 tools between 5 and 10 years, 17 tools between 5 and 10 years, 18 tools < 20 years<br>
<br>
Be well,<br>
