Dear All,
Good Morning to u all !!!!!!!!!!!
Pl find below nature of problem related to turret indexing in subject machine
- When we do turret indexing say for 15 times then clamp is OK that means no vibration/jerk during clamping but after that we get vibration/jerk when turret clamps & so it hits the Proximity bracket for turret clamp/unclamp proximity & then reference position of turret also shifts . Now during every indexing, we get vibration/jerk when turret clamps & so it hits the Proximity bracket for turret clamp/unclamp proximity.
- When we do turret home(by putting switch at station 1 & then pressing turret index 1 & zero return together) then reference position of turret is OK again, turret indexing say for 15 times is OK that means no vibration/jerk during clamping but after that we get vibration/jerk when turret clamps & so it hits the Proximity bracket for turret clamp/unclamp proximity & then reference position of turret also shifts
4. Inroduced M45 in program so that turret rotates in single direction to avoid effect of backlash in Gear box but with this also indexing position is not accurate
- We adjusted screw C on turret hydraulic valve block to the minimum & now turret clamping is very smooth & it takes little longer to clamp but no alarm but in this setting also say after indexing turret for 20 times, suddenly that we get vibration/jerk when turret clamps & so it hits the Proximity bracket for turret clamp/unclamp proximity & then reference position of turret also shifts
We need to make use of only two toold in this machine
Please advice on how to overcome backlash in turret gearbox
