CNC machine operation and monitoring of all completed in the numerical control unit, which is the brains of CNC machine tools. Com

pared with the general machine tools, CNC machine tools has the following characteristics: ● high precision, stable processing quality; ● can be multi-axis linkage, can process complex shape parts; ● processing part changes, generally only need to change the NC program, saving the production time to prepare; ● high precision machine tool itself, rigidity, can choose the amount of benefit processing, production rate (usually as an ordinary machine 3 to 5 times); ● high degree of automation tools, can reduce labor intensity; ● the quality of the operators require a higher technical requirements on higher maintenance staff.

CNC machine tools generally consists of the following components:
● host, he is the subject of CNC machine tools, including machine tools, column, spindle, feed mechanism and other mechanical parts. He is used to complete a variety of machining mechanical parts. ● CNC equipment, CNC machine tools is the core, including the hardware (printed circuit boards, CRT monitors, key boxes, paper tape reader, etc.) and the corresponding software for digital input part program, and complete the input information storage, data transformation, interpolation operations and achieve a variety of control functions. ● drive, he was the implementing agencies CNC drive components, including the spindle drive unit, feed unit, spindle motor and feed motor. He was under the control of the NC device electrical or electro-hydraulic servo system to achieve through the spindle and feed drive. When several feed linkage, you can complete the position, line, plane curves and

Position control; point control of CNC machine tools is characterized by moving parts of the machine can be achieved only from one location to another precise movement and

positioning of the process in motion without any processing operations. Such as CNC drilling machines, a few at coordinate boring machine, CNC welding and tube bending machines. Linear control; point linear control characteristic is not only moving parts of the machine coordinates to achieve a precise location to another movement and positioning, but also to achieve a straight line parallel to the axis feed movement or control of the two oblique axes to achieve line feed movement. Contour control; contour control the characteristics of CNC machine tools is the machine moving parts to achieve two axes simultaneously control linkage.

CNC Machine Tools Return troubleshooting
Manual reference point return operation of the machine coordinate system is built on the premise, most of the first CNC machine is turned on manually operated actions are generally the reference point. If the reference point back to the failure processing program will not be able to return the position of the reference point will not affect the accuracy of machining accuracy, or even crash. Analysis and excluded the issue back to the reference point of failure is necessary. CNC machine tools in the supply and demand information on Alibaba>>> http://search.china.alibaba.com/search/offer_search.htm?keywords =% CA% FD% BF% D8% BB% FA% B4% B2 1. Back to the main types of reference point of failure A CNC machine operator training center has 20 CNC machine tools, and is purchased in batches, the system more types of students training in the operation, there have been back several times reference point of failure, through the timely analysis was excluded. According to experience, different systems in different models of CNC machine tools, there back to the reference point of failure, mainly in the following five categories: super-way there and the police; back less than a reference point, the reference point indicator does not light; back to the reference point instability; back to the whole pitch offset reference point; back to the reference point the alarm, and alarm information. 2. Back to the reference point troubleshooting The process occurs over and the police, divided into two cases. One case is the reference point before the position of the axes from the reference point resulting from too

small. Lift overtravel protection, and will move to the travel axis within the scope of the reference point to re-operation, to troubleshooting; other is the "reference point deceleration" block loose or change position due to failure to re-adjust the fixed block to be troubleshooting. Back to the reference point due to the amount of the reference point indicator is off. Diagnostic capabilities through the machine in the diagnosis of the page under the corresponding "Location tracking error" (dgn800 ~ 802) to check if the positioning accuracy of the tracking error exceeds the permissible range, you can adjust the servo drive, "offset" potentiometer so that the " Position tracking error "(dgn800802) value close to" 0 ", you can troubleshoot. There reference point for the unstable failure, first check the location and block exposure, and then check the pulse encoder "zero pulse" if there are problems, the last check the gap between the motor and lead screw. If the unstable displacement error is small, usually among the last case, the gap should be eliminated to remove a loose connection. Reference point the whole pitch shift. When the workpiece is always stable displacement error occurred, and exactly equal to the screw pitch, then the problem lies in the back reference point. Reference points are generally located in the "reference point slow down" after the opening of the first block of a "zero pulse" on. If the block release, the encoder happens in the "zero pulse" in the vicinity, there will be a whole pitch shift. Need to re-adjust the deceleration stop position, preferably slow release position and the block encoder "zero pulse" position, a difference of half a pitch. Back to the reference point for the alarm, and fault alarm. For alarm information, view the machine instructions for the appropriate treatment. Message alert may belong to: encoder "zero pulse" and the system grating bad bad bad shield, the system parameter setting error and other failures. For the hardware bad need of repair or replacement; for parameter setting error, you need to reset the parameters by backups. 3. Conclusion Occur during the operation of CNC machine tools back to the reference point failure, mainly in the areas, according to the principle of the reference point, can conduct the investigation step by step in order to find the key to apply the correct method of troubleshooting.

对于出现超程并报警,分为两种情况。 一种情况是回参考点前,坐标轴的位置离参考点距 离过小造成的。解除超程保护后,并将坐标轴移动到行程范围内,重新回参考点操作,即可排 除故障;另一种是“参考点减速”挡块松动或位置发生变化引起的故障,重新调整固定挡块 就可以排除故障。 回参考点欠量,参考点指示灯不亮。 通过机床的诊断功能,在诊断页面下对应的“位置跟 随误差” (dgn800~802) 进行检查,若跟踪误差超出了定位精度的允许范围,可以调整伺服驱 动器的“偏移”电位器,使“位置跟随误差” (dgn800802) 的值接近“0”后,就可以排除故 障。 对于出现参考点的位置不稳定的故障,首先检查挡块的位置和接触情况,然后检查脉冲 编码器“零脉冲”是否有问题,最后检查电动机与丝杠之间的间隙。如果不稳定的位移误差 很小时,一般属于最后一种情况,应该消除间隙,消除连接松动。 参考点整螺距偏移。 在加工工件时,总是发生稳定的位移误差,而且正好等于丝杠的螺距, 那么,问题就出在回参考点上。参考点一般都是设在“参考点减速”挡块放开后的第一个 “零脉冲”上。 若挡块放开时,编码器恰巧在“零脉冲”附近,就会出现整螺距偏移。 需要重 新调整减速挡块位置,最好是减速挡块放开位置与编码器“零脉冲”位置相差半个螺距。 对于回参考点时报警,并有报警信息的故障。针对报警信息,查看机床说明书,作相应处 理。信息提示可能属于:编码器“零脉冲”不良及系统光栅尺不良、屏蔽线不良、系统参数 设置错误等故障。对于硬件不良,需要维修或更换;对于参数设置错误,需要按备份参数进行 重新设置。 3.结语 数控机床操作过程中出现回参考点故障时,主要发生在上述几个方面,根据回参考点的 原理,就可以按顺序分步骤地进行排查,找到关键所在,应用正确的方法排除故障。 数控机床重大专项重点服务四大领域 2 月 4 日,中国机床工具工业协会总干事长吴柏林告诉中国工业报记者,“高档数控机 床与基础制造装备重大专项指南”将在本月中旬发布,这意味着 16 个国家科技重大专项当 中最后实施的一个专项即将启动。
