External Factors that can affect accuracy on Stuga Machines

Sommaire

There are many external factors that can affect the accuracy of Stuga machines. it is incredibly important that these factors are all eliminated as potential root causes.

If you do suspect that one of these factors is potentially a problem, it is equally important to be able to prove and demonstrate your suspicions clearly.

External Factor Description Link to Page Affected Machines
Temperature change Profiles expand around 0.5-1.0mm per 10 degree in temperature change

If the bar temperature changes between machining and sawing, the bar expands and accuracy is compromised

Flowlines

ZX3 / 4/ 5

Profile Width Depth of front V and Y notches depends on the profile width

Arrow head position depends on profile width (Autoflow and Microline only)

All
Innaccurate welders Finished Y notch depth depends heavily on reverse butt burn-off
Incorrect link data (Y notch codes) Machine will cut to the depth that it is told
Profile symmetry

Profile left on TT overnight
Bowed profile

Tolerances (+/- 0.5mm)
Customer expectation
