CNC lathe tool rest common trouble and repair

numerical control technology and the use of the nc machine tools, and successfully solves some shape, high consistency, small batch parts in the initiative, which not only greatly advances the produce power and machining precision, also reduced the labor intensity of workers, shortened the production preparation cycle. But, in the process of using numerical control lathe, numerical control lathe will inevitably appear all sorts of trouble, so the problem of repair is a CNC lathe using zui crucial question. On the one hand, selling the company after-sales service can not be timely to ensure, on the other hand to grasp some repair technology to quickly distinguish fault location, shorten the repair time, let the equipment operation up quickly. In daily problem, we often meet the tool post, spindle, screw machining, system display, drive, communication etc. And the rest of order occupied large proportion in it. Here, introduce classification in daily operation to meet four station electric tool post all kinds of problems and corresponding solutions, expecting to offer some beneficial reference for us. The numerical control system is used in guangzhou nc series produced by GSK CNC system. CNC lathe trouble phenomenon one: electric tool slide lock is not tight (1) transmitting plate bearing not to is: open tool slide lid, twisted and adjust the transmitting dish azimuth, make the hall element alignment of the tool carrier magnetic steel, tool stops in the accurate location. (2) the system locks the moment not governor: adjust system locked time parameters ( The new locks the tool rest time t = 1. 2 s) 。 (3) mechanical locking mechanism problem: disassemble the tool rest, adjust the machine, and check whether the positioning pin is broken. Trouble phenomenon. 2: electric tool post number one knife turn continuously, the other tool can roll (1) the knife hall element damage: a dao which is turn, rest on the system input command scroll the tool, the cutter location signal contact by the multimeter to + 24 v contact if there is a voltage change, without change, can be judged the knife hall element damage, the transmitting tray or hall element. (2) the tool break line, form a system in place signal cannot be detected: check the tool of the attachment whether there is open circuit, signal and system cohesion can be correctly. (3) system of the knife a signal receiving circuit has a problem: when we determine the knife a hall element is no problem, as well as the tool of signal and system connection is no problem under the condition of replace the motherboard.
