KIQ16 CNC B数控立式车削中心是捷克HULIN公司于上世纪90年代制造，采用FANUC-BASK 6T数控系统。由于该机床已经使用10余年，加之数控系统更新换代，FANUC-BASK 6T数控系统早已停产，系统板件老化，备件昂贵。采用新型数控系统对该机床进行改造势在必行，这样可使该机床重新焕发活力，更好地发挥机床的潜力。
改造方案的制定
该机床原有功能齐全，包括主轴(工作台)和铣磨轴的旋转运动、X、Z轴坐标运动、15个刀位的刀库系统，还有诸如冷却系统、液压系统、润滑系统、排屑系统等机床功能。主轴和铣磨轴采用直流电动机及直流调速器。X、Z轴坐标也采用直流伺服电机及直流伺服调速器。刀库采用普通三相异步交流电动机，由5位二进制凸轮定位。该机床的机械部分各方面机械性能良好稳定、精度尚可、液压系统工作正常，因此上述部分基本保持不变。
数控改造更换数控系统和电气控制部分，采用SIEMENS SINUMERIK 802D数控系统。X、Z轴和刀库坐标伺服驱动系统采用SIIMODRIVE 611UE变频驱动系统和1FK7伺服电机，选用脉冲编码器作为位置检测元件，达到数字伺服驱动系统闭环控制。主轴和铣磨轴驱动系统采用英国Eurotherm公司的590+系列直流电动机调速装置。改造机床其他电气控制线路，更换电气控制元件，保证机床各种控制功能和操作的实现，保证机床电气控制部分长期可靠工作。
除增加MCP机床控制面板外，还要重新设计机床操作面板，具有各种机床功能按钮和指示灯。
数控系统和坐标伺服驱动系统
SIEMENS SINUMERIK 802D数控系统是将所有CNC、PLC、HMI和通讯任务集成，是基于PROFIBUS总线的数控系统。免维护硬件集成PROFIBUS接口用于驱动和I/O模块并具有速装结构的操作面板。SINUMERIK 802D数控系统控制X、Z轴和刀库三个数字进给轴和一个主轴。该机床采用二块I/O模块PP72/48和机床操作面板MCP。利用TOOLBOX 802D中PROGRAMMING TOOL PLC 802软件编写PLC控制程序，调用PLC子程序库中的SBR32 PLC-INI PLC初始化、SBR33 EMG-STOP 急停处理、SBR34 MCP-802D 传送机床控制面板对应I/O状态、SBR38 MCP-NCK 机床控制面板MCP信号、操作面板HMI信号送至NCK接口、SBR39 HANDWHL 由操作面板HMI在机床坐标系或工件坐标系选择手轮、SBR40 AXIS-CTL 进给轴和主轴使能控制。由于子程序是标准的车床控制程序，这样与该机床实际情况不同，刀库采用数字轴控制，增加了数字轴的数量。在机床控制面板和进给轴和主轴使能控制等子程序中都要做一定的修改。立式车削中心有别于一般的卧式车床，所以坐标方向也有所不同，还需要子程序做相应的修改。

New SINUMERIK 802D CNC system on the use of more than 10 years of SKIQ16 CNC B Vertical Turning Center of NC, NC Machine Tool powerful features greatly broadened the scope of machining parts, and better ensuring the processing of parts the consistency and quality of products. This article was the second SINUMERIK NC application essay activities and the transformation of a prize-second prize.
KIQ16 CNC B Vertical Turning Center in the Czech HULIN companies in the 1990s manufacture, use FANUC-BASK 6T CNC system. Since the machine had been in use for more than 10 years, and the NC system upgrading, BASK 6T-FANUC CNC system has been shutdown, system board of aging, expensive spare parts. A new CNC machine tools to transform the system is imperative so that the machine can restore vitality, and give better play to the potential of machine tools.
Transformation programme development
The original full-featured machine, including spindle (table) and the rotation axis milling campaign, X, Z-axis coordinates of movement, 15 knives in a knife library systems, and such as the cooling system, hydraulic system, lubrication system , Paixie system functional machine. Spindle axis and milling by DC and DC motor speed regulator. X and Z-axis also coordinates by DC servo motor and DC servo governor. The knife used ordinary three-phase asynchronous AC motor from the five binary cam positioning. The mechanical part of the machine all good mechanical properties of stability, accuracy fair and normal hydraulic system, the part of the capital remain unchanged.
NC system and the replacement of electrical control part, by SIEMENS SINUMERIK 802D CNC system. X and Z axes and knives coordinates the servo drive system uses SIIMODRIVE 611UE variable frequency drive system and a FK7 servo motor, encoder pulse chosen as a location detection devices, digital servo drive system to achieve closed-loop control. And milling spindle axis drive system by the British company's 590 + Eurotherm Series DC motor speed control device. Machine control of other electrical lines, the replacement of electrical control devices to ensure that all kinds of machine control function and operation of the realization of the electrical control machine tools guarantee a long-term reliable work.
Apart from increasing MCP machine control panel, we must also re-designed machine operator panel with all types of machine function buttons and lights.
