概要: 具有更高的静态和动态风味。立式加工底座价格昂贵,其加工成本比传统的机床来求更多,这就要求使用方法来大幅拧紧单件的加工时间。拧紧单件的加工时间包括两个方面,一方面,开发新的刀具材料,常规切削速度成倍地向前推进,大大缩短了切削时间; 另一方面,选用自动换刀系统,加快装夹换刀等操作,大大减少了辅助时间。这些方法大大提高了生产率,获得了良好的经济效益,同时也显著增加了机床的负荷和运行时间。
1,具有较高的静态和动态风味。立式加工底座价格昂贵,其加工成本比传统的机床来求更多,这就要求使用方法来大幅拧紧单件的加工时间。拧紧单件的加工时间包括两个方面,一方面,开发新的刀具材料,常规切削速度成倍地向前推进,大大缩短了切削时间; 另一方面,选用自动换刀系统,加快装夹换刀等操作,大大减少了辅助时间。这些方法大大提高了生产率,获得了良好的经济效益,同时也显著增加了机床的负荷和运行时间。在加工底座结构的规划中,考虑到这些,因此,大件的根部一般选用封闭的箱体结构,合理放置加强板以及加强构件的联系我们风,有利于提高整机的静风。别的,调剂元件的质量可以或许转变体系的自振频率,增长阻尼可以改良机床的阻尼特征,是进步机床动力学魅力的有用门路。
2, with static stiffness. Machine tool bed, guideway, table, tool holder and spindle box and other components of the structural rigidity will affect his own precision and deformation due to the error occurred. All of these elements require CNC machine tools have a higher static stiffness. Vibration in the cutting process not only directly affects the machining accuracy and surface quality of the parts, but also reduces tool life, affecting productivity. The machining base is a continuous operation, may not be in the processing of artificial adjustment (such as changing the amount of cutting or changing the angle of the tool a few) to eliminate or reduce the vibration, therefore, it is necessary to advance the base of the dynamic stiffness of the machining.
3,有较小的热变形。加工基体在加工中受到切削热、电阻热等表面热源的影响,零件会发生不同程度的热变形,从而影响工件的加工精度。由于加工底座的主轴转速、进给量和切削用量均大于传统机床,且工艺过程自动化,经常连续加工,因此产生的热量多采用液体冷却、购冷等方法控制温升;改善机床结构,使构件的热变形发生在主动方向的非差异方向上。例如,卧式加工底座的立柱选择框架双柱结构,主导对称性,热变形主轴轴线上升方向平移,它可以通过坐标校正来补偿是为了尽可能地减少热量,热源要从主机中分离出来。
4、运动部件之间的联系我们小,切割驱动系统的开放空间。加工基座工作台的位移以脉冲当量为最小单位,在对刀等情况下,工作台经常以非常低的速度移动。这就要求工作站能对数控设备所宣布的指令做出准确的响应,这与运动部件的联系我们特性有关,加工底座选用滚转导轨、滚转导轨和静压导轨的静联系我们力要小,并且在润滑油,它们的联系我们力随着运动速度的推进而减小,这有利于避免低速爬行现象,使加工底座的运动平衡和定位精度都得到推进。在进给系统中,滚珠丝杠用于代替滑动丝杠,这也是基于相同的推理。别的,利用脉冲补偿设备进行螺距补偿,除了进给驱动系统的开放空间外,也有机床选择无开放空间传动副。
5, high longevity, good precision adherence. Outstanding lubrication system ensures the longevity of the vertical machining base, guide rail, feed screw and spindle parts are used in new wear-resistant materials, so that the machining base in the long-term use of the process can adhere to the excellent accuracy.
6、Humanization plan. The machining base adopts spindle, multi-tool holder and automatic tool changer, which saves a lot of time for tool change by finishing multi-process machining in one clamping. Because it does not need manual operation, it chooses closed or semi-closed processing, so that the man-machine interface is bright, clean and harmonized. The machine tool has strong interlocking ability, which can avoid the occurrence of incidents, improve the operator's query, operation and protection conditions, and there is an emergency parking equipment to avoid accidents, all the operations are gathered in an operation and the board, at a glance, reducing the misoperation.
