A frustrating issue solved for our customer on his XYZ Vulcan 250. This turning centre was suffering with intermittent turret clamp / unclamp faults which was disrupting production of ventilator components.
After a quick investigation we found there was excessive backlash on the intermediate gear within the turret, caused by the keyway rolling over and the collar on the intermediate shaft had broken free and was slipping causing the lateral movement of shaft during clamp / unclamped operation to be compromised.
We were able to repair the shaft by welding it up and regrinding and eliminate the backlash by using an oversize key. Since being reassembled it hasn’t missed a beat or faulted once. A 17 year old machine back to producing at full capacity for NHS proactive components.
