Mechanical issues that can affect accuracy on Stuga machines

Sommaire

Back To General Accuracy Guidelines


The Mechanical systems on a machine are all prone to wear and tear, maladjustment, alignment, swarf ingress, lack of lubrication and collisions.

It is vital that all mechanics of the system are fully checked out and set and working correctly before any software adjustments are carried out

Mechanical Issue Description Link to Page Common Symptoms Affected Machines
Recent gripper crash - alignment Following a gripper crash with profile, gripper position is out / does not grip properly Gripper does not pick up profile correctly

Gripper assembly is loose

All

Particulalrly Autoflow

Backlash in Ring Ring gearing is worn and has developed backlash Operation position in Y and Z varying randomly
Clamp Pressures - MH and Saw Clamp pressures have been incorrectly adjusted and profile is not clamping correctly - ie not pushed to backfence /
Backlash Racks
Pinion gear wear
Gripper nose / gap
Clamp / Rollers alignment
Saw Clamp parallelism
Saw kerf
Saw angles
G axis Parallel to Rear Rollers -ZX4
G axis parallel
G axis datum
Laser alignment Used where Machine cannot do a Trim Start and is the Datum point End of Bar https://stuga.dokit.app/wiki/Laser_Setup_on_Flowline/ZX3_for_Laser_Holes Laser Hole Errors, Operational position in X axis varying randomly


ZX3 and ZX4 Non All in One Versions
