     In daily failures, we often meet the turret type, spindle type, thread processing class, the system displays the type, drive type, communications and other failures. The toolholder in which a large proportion of fault. Here, the classification introduce daily work to meet the four-position electric turret various types of failures and corresponding solutions.Symptom one: electric holder lock is not tight
TROUBLE CAUSE
① letter of the disk position is not positive: apart turret top cover and adjust the transmit rotating disk position, the tool post of the Hall element is aligned magnets, the cutter bit at the exact location.
② system locked time is not long enough: adjust the system time parameters can be locked (new turret can be locked time t = 1.2s).
③ mechanical locking mechanism failure: open turret, mechanical adjustment and check the positioning pin is broken.
Symptom 2: an electric tool a knife, go non-stop, and the remaining bits can be rotated knife
TROUBLE CAUSE
① This bit knife Hall element damage: confirmation is a tool which enables turret rotation stop position, rotation of the tool position input command on the system, the amount with a multimeter tool position signal contact to + 24V contacts for voltage changes If there is no change in that position can be determined knife Hall element is damaged, replace the transmission disk or a Hall element.
② This tool selection signal line circuit, causing the system can not detect the position signal: Check the tool position signal and system wiring for open circuit, can be connected correctly.
Knife ③ signal receiving circuit system has a problem: when it is determined that this location of the Hall element is no problem, and the tool position signal and system wiring is also no problem to replace the motherboard under the circumstances
