    2020-2-12 11:45:41

    数控机床的操作和监控全部在这个数控单元中完成,它是数控机床的大脑。与普通机床相比,数控机床有如下特点:

    The operation and monitoring of CNC machine tools are all completed in this CNC unit, which is the brain of CNC machine tools. Compared with ordinary machine tools, CNC machine tools have the following characteristics:

    1、对加工对象的适应性强,适应模具等产品单件生产的特点,为模具的制造提供了合适的加工方法;

    1. It has strong adaptability to machining objects, adapts to the characteristics of single production of products such as molds, and provides suitable processing methods for mold manufacturing;

    2、加工精度高,具有稳定的加工质量;

    2. High machining accuracy and stable machining quality;

    3、可进行多坐标的联动,能加工形状复杂的零件;

    3. It can carry out multi coordinate linkage and process parts with complex shape;

    4、加工零件改变时,一般只需要更改数控程序,可节省生产准备时间;

    4. When the machining parts are changed, generally only the NC program needs to be changed, which can save the production preparation time;

    5、机床本身的精度高、刚性大,可选择有利的加工用量,生产率高(一般为普通机床的3~5倍);

    5. The machine tool itself has high precision and rigidity, so it can choose favorable processing amount and high productivity (generally 3-5 times that of ordinary machine tools);

    6、机床自动化程度高,可以减轻劳动强度;

    6. The machine tool has a high degree of automation, which can reduce the labor intensity;

    7、有利于生产管理的现代化。数控机床使用数字信息与标准代码处理、传递信息,使用了计算机控制方法,为计算机辅助设计、制造及管理一体化奠定了基础;

    7. It is conducive to the modernization of production management. CNC machine tools use digital information and standard code to process and transmit information, and use computer control methods, which lays a foundation for the integration of CAD, manufacturing and management;

    8、对操作人员的素质要求较高,对维修人员的技术要求更高;

    8. The quality requirements of operators are higher, and the technical requirements of maintenance personnel are higher;

    9、可靠性高。

    9. High reliability.

    数控机床与传统机床相比,具有以下一些特点。

    Compared with traditional machine tools, CNC machine tools have the following characteristics.

    1、具有高度柔性

    1. Highly flexible

    在数控机床上加工零件,主要取决于加工程序,它与普通机床不同,不必制造,更换许多模具、夹具,不需要经常重新调整机床。因此,数控机床适用于所加工的零件频繁更换的场合,亦即适合单件,小批量产品的生产及新产品的开发,从而缩短了生产准备周期,节省了大量工艺装备的费用。

    Machining parts on CNC machine tools mainly depends on the processing program. Unlike ordinary machine tools, it does not need to manufacture, replace many molds and clamps, and often readjust the machine tools. Therefore, CNC machine tools are suitable for the occasion of frequent replacement of processed parts, that is to say, it is suitable for the production of single and small batch products and the development of new products, so as to shorten the production preparation cycle and save a lot of costs of process equipment.

    2、加工精度高

    2. High machining accuracy

    数控机床的加工精度一般可达0.05—0.1MM,数控机床是按数字信号形式控制的,数控装置每输出一脉冲信号,则机床移动部件移动一具脉冲当量(一般为0.001MM),而且机床进给传动链的反向间隙与丝杆螺距平均误差可由数控装置进行曲补偿,因此,数控机床定位精度比较高。

    The machining accuracy of CNC machine tools can reach 0.05-0.1mm in general. CNC machine tools are controlled by digital signal. For each pulse signal output by CNC device, the moving parts of the machine tool move one pulse equivalent (generally 0.001mm), and the average error between the reverse clearance of the feed chain and the screw pitch of the machine tool can be compensated by the CNC device. Therefore, the positioning accuracy of CNC machine tools Relatively high.

    3、加工质量稳定、可靠

    3. Stable and reliable processing quality

    加工同一批零件,在同一机床,在相同加工条件下,使用相同刀具和加工程序,刀具的走刀轨迹完全相同,零件的一致性好,质量稳定。

    Machining the same batch of parts, in the same machine tool, under the same processing conditions, using the same tool and processing program, the tool path is exactly the same, the consistency of parts is good, and the quality is stable.

    4、生产率高

    4. High productivity

    数控机床可有效地减少零件的加工时间和辅助时间,数控机床的主轴声速五轴联动加工中心和进给量的范围大,允许机床进行大切削量的强力切削。数控机床正进入高速加工时代,数控机床移动部件的快速移动和定位及高速切削加工,极大地提高了生产率。另外,与加工中心的刀库配合使用,可实现在一台机床上进行多道工序的连续加工,减少了半成品的工序间周转时间,提高了生产率。

    CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The acoustic speed of the spindle of CNC machine tools five axis linkage machining center and the range of feed amount are large, allowing the machine tools to carry out strong cutting with large cutting amount. CNC machine tools are entering the era of high-speed machining. The rapid movement and positioning of moving parts of CNC machine tools and high-speed machining greatly improve productivity. In addition, with the use of the tool magazine of the machining center, it can realize the continuous processing of multiple processes on a machine tool, reduce the inter process turnover time of semi-finished products, and improve the productivity.

    5、改善劳动条件

    5. Improve working conditions

    数控机床加工前是经调整好后,输入程序并启动,机床就能有自动连续地进行加工,直至加工结束。操作者要做的只是程序的输入、编辑、零件装卸、刀具准备、加工状态的观测、零件的检验等工作,劳动强度大降低,机床操作者的劳动趋于智力型工作。另外,机床一般是结合起来,既清洁,又安全。

    Before NC machine tool processing, after adjustment, input program and start, the machine tool can automatically and continuously process until the end of processing. All the operator has to do is to input and edit the program, load and unload the parts, prepare the cutting tools, observe the processing state, and inspect the parts. The labor intensity is greatly reduced, and the labor of the machine operator tends to be intelligent. In addition, machine tools are generally combined, clean and safe.

    6、利用生产管理现代化

    6. Modernization of production management

    数控机床的加工,可预先精确估计加工时间,对所使用的刀具、夹具可进行规范化,现代化管理,易于实现加工信息的标准化,已与计算机辅助设计与制造(CAD/CAM)有机地结合起来,是现代化集成制造技术的基础。

    The machining time of CNC machine tools can be estimated accurately in advance, the tools and fixtures used can be standardized, modern management can be realized, and the standardization of machining information can be easily realized. It has been organically combined with CAD / CAM, and is the basis of modern integrated manufacturing technology.
