　　随着国家“十一五”节能减排政策的贯彻落实，门窗行业对于型材的节能效果也提出了新的要求。传统的铝合金门窗由于型材本身的特点—— 传导散热快，对于在冬季有效保持室内温度的要求不能有效的满足，节能效果较差。新型的铝塑门窗利用塑料型材 ( 隔热性高于铝型材 1250 倍 ) 将室内外两层铝合金既隔开又紧密连接成一个整体，比普通门窗热量散失减少一半，降低取暖费用 30% 左右，成为门窗行业新的发展趋势。
　　门窗型材的变化推动着门窗加工设备的种类逐渐细化、品种逐渐多样化，对生产工艺也有了更高的要求。门窗型材锯切作为门窗生产流程的重要环节，其加工精度直接影响门窗的质量与生产效率。目前铝塑型材锯切机床的加工精度较低，锯切后的铝型材主要靠后续的安装弥补锯切时的误差，塑料型材靠后续的焊接弥补锯
　济南伦渠数控机电有限公司专业生产各种铝塑加工设备，针对新型的切割锯设备性能需求，提出了以西门子最新推出的小型 PLC S7-200 SMART 作为主控制器，同时采用了 SMART LINE 触摸屏和 SINAMICS V60 伺服驱动器。整套的西门子小型自动化解决方案优化了设备性能，调试也更加便利，其基本性能如下：
　　(1) 效率高：运行速度可达每分钟 20 米，切割 3mm 铝板速度可达到 1.5 ～ 3m/min;
　　(2) 切力大：切割深度可达 3 ～ 8mm，切割口平滑，无毛边，不变形;
　　(3) 精度高：能进行准确定位，定位精度可达 0.02mm;
　　(4) 性能稳定：可 24 小时不间断作业，废品率低;
　　(5) 功能丰富：拥有断点、断电复位，加工时间预测等功能。
　　2.2 切割锯原理结构
　　铝塑门窗双头切割锯由机械系统和电气系统构成，前者包括锯头、固定机头、移动机头、移动机头拖动装置、床身、托料架等机械结构，后者由电气箱、电气控制操作台等电气系统及气动系统组成，用于实现对型材定尺定角度切割下料设备的控制。铝塑门窗双头切割锯上的切割刀具使用硬质合金齿锯片，切削速度快、效率高、加工精度高。该机也可用于木料加工，其两个机头可单独工作也可同时工作，一次切出需要的长度及切口角度。
　　(1) 锯头。锯头部分由左、右锯头组成。左锯头为固定锯头，右锯头随拖板在圆导轨上左右移动。拖板与导轨之间有直线运动副。锯头的左右运动轻快、灵活，保证了运动的平稳性。锯片的进给由双作用气液阻尼缸完成。其气动控制系统具有无极调速的功能，根据加工需要，可调节其进给及返回的速度，使之具有慢速进给快速返回的功能;
　　(2) 床身。床身由低碳钢矩形钢管焊接而成，焊接后经时效处理，保证了床身的刚度及稳定性;
　　(3) 工作台。固定工作台和左锯头装在一起，活动工作台随拖板在导轨上可左右水平移动。
