熄灯加工促进转动容量

A Colchester Tornado A50 CNC lathe, equipped with a bar feed, Renishaw probing, tool monitoring, pickoff unit, swarf conveyor and production-scheduling software, is providing lights-out production capability for Altex Engineering, a (Calne, Wiltshire) U.K. precision subcontractor that specializes in turning and milling in addition to sheet metal fabrication using laser cutting, punch press and folding equipment. With the new CNC lathe, Altex has increased productivity by more than 50 percent on a range of turned components, some 80 percent of which are now completely machined in a single setup.

With the new CNC lathe, Altex has increased productivity by more than 50 percent on a range of turned components, some 80 percent of which are now completely machined in a single setup. Altex expects even better results as it gains more experience with all of the machine’s automation features. The turning side of Altex’ business includes a range of components for vending machines, office equipment, lighting, materials handling, health care and other products, in batch sizes from 500 to 1,000. Materials machined include mild steel, stainless, aluminum, brass and nylon. The components produced on the A50 range in size from around 0.4 inch to 1.5 inches in diameter.

这台机器在白天基本上无人看管。根据生产计划和正在运行的工作类型,车床可以在晚上完全无人值守的情况下运行。“熄灯工作”被视为在几乎没有额外成本的情况下提供额外的周转能力,它是帮助缩短某些工作的交货时间表的一个重要因素。在白班期间,一名操作人员负责A50和另外两架科尔切斯特龙卷风车床的安装、bar补充和部件检查。

一旦A50设置并运行,它就很少需要任何偏移调整以保持容差。基于扭矩的工具监控系统感应磨损或损坏的工具。当达到既定限制时,软件停止机器以通过操作员更换磨损的工具,或者告诉机器使用安装在另一个凸起位置的备用工具。

操作员可以随时检查FANUC控制的屏幕,以实时监控实际的工具装载。工具磨损寄存器随着所需扭矩水平的增加。Altex发现,在表面光洁度和工具磨损模式方面,系统会获得非常一致的结果。

棒饲料系统是完全集成的机器,使它可以在发那科控制编程。无机械停机设置,转换时间不超过15分钟。每根棒子都被测量,然后软件计算出每根棒子可以生产的零件数量。根据这些信息,系统自动重新计算有多少块碎片留给龙卷风机器,然后停止循环。

Toronado A50,可购自Clausing Industrial Inc.(Kalamazoo,密歇根州),具有42毫米直径的棒容量和12站炮塔。由7,000-RPM主轴的恒定表面速度由7.5-HP电机提供动力,确保良好的表面光洁度。控制来自FANUC 21-TI系统。简短的洋切斯特设计的杂志型杆供给允许车床以最佳速度运行而不振动,因此始终保持工件表面光洁度标准。
