Symptom 2: A center frame a knife, go non-stop, rest cutter approach can turn the cause of the failure of this bit knife ① Hall element damage: Make sure cutter which enables turret rotation stop Qinghai professional custom center frame Shenyang First Machine Tool Plant input commands on the system of rotation of the cutter Liaoning professional custom center frame, with a multimeter the tool signal contacts on the + 24V contact if there is a voltage change, without change, the knife can be determined that the bit Hall element is damaged, replace the transmission pan or a Hall element; ② This tool signal line circuit, causing the system can not detect the position signal: Check the wiring of the tool signal and system exists circuit, can properly connected; ③ System The tool signal receiving circuit there is a problem: When it is determined that this location is no problem Hall element and the tool signal wiring systems also replace the motherboard with no problem under the circumstances. When using the first adjustment of the position of the center frame, so that the roller holder is held in the center of the support surface of the center frame complete, as follows: the base of the center frame is loosened in front of the locking bolt, to adjust the right side of the center frame pin position, into the empty slot pallet Fujian professional custom center frame, moving pallets immediately after the position is determined to return the pin, locking the front bolts. Base rail center frame using timed manual lubrication methods, class work should be lubricated once before. Clamped parts must have sufficient space to be clamped, the clamped surface must be processed, good surface finish, otherwise it will destroy the entire center of the wheel and the frame. Tolerances within ± 2mm of parts is no impact on the holding precision (repeatability of positioning accuracy 0.005 ~ 0.01mm).
