Has anybody with a mazak or hyundai qt15n ever experianced the chuck not opening when commanded on occasion?
Sometimes it take me 2 or 3 presses of the foot pedal to get the chuck to open which is no real issue when running parts 1 at a time but when i set up to bar pull and want to leave it running sometimes it will be fine for 50 parts and then another time it will not work for 25 of the 50 parts so the chuck times out and the errors say 'chuck clamp time exceeded'
When you press the pedal you can hear a solenoid/relay set up click which is obviously to do with the hydraulic pressure switches but ive found nothing obvious, oil level is good, hydrualic fluid is good, foot pedal switch is good
Without completely stripping down the entire hydrualic system which i dont want to do, does anybody have any ideas?
Thanks
Marc
