Unfortunately a chop saw is only as good as the idiot in control of it... this applies to all machines unfortunately. To a general company that will be about right squareness and length wise... different people and different trades have different idea of what is right.

If you go to a proper machine shop and you tell them what you want then you should get what you need. Again the job is only as good as the information you give them, make sure you specify what you actually need rather than leaving them to their own devices and deciding for you. This should have been done against a dead stop which in saw terms could still be + or - .25mm pending the saw and the guy in control of it.


I think your best option is to find someone with a mill and get them to square the ends up against dead stop. Mill one end and debur... rotate 180 and repeat against a dead stop. You will get accurate and square ends that way if you need them that good. I use this process a lot for getting repeatability on longer parts.
