   由于铝板加工中心设备远比普通机床昂贵,所以受到的制约因素更多,机床选择合理与否就更显重要。正确选型是用好加工中心、使加工中心设备发挥效益的关键。在购买铝板加工中心设备时,认真考察这五大要点尤为重要:
Because the equipment of aluminum plate machining center is much more expensive than ordinary machine tools, so it is more important to choose reasonable machine tools. Correct selection is the key to make good use of machining center and make the equipment of machining center play an important role. When purchasing aluminum plate processing center equipment, it is particularly important to carefully investigate these five key points:
1、加工设备的刚度 铝板生产厂家
1. Rigidity of processing equipment
由于加工中心设备的刚度直接影响机床的生产效率和加工精度,所以加工中心的加工速度远高于普通机床,电机的功率也高于普通机床同一规格的普通机床,其结构设计的刚度远高于普通机床。订货时,可根据制造厂提供的数值,校核工艺要求、允许扭矩、功率、轴向力和进给力的最大值。为了获得机床的高刚度,往往不局限于零件尺寸,而是选择相对零件尺寸大于1~2规格的机床。
Because the rigidity of the machining center equipment directly affects the production efficiency and machining accuracy of the machine tool, the processing speed of the machining center is much higher than that of the ordinary machine tool, the power of the motor is also higher than that of the ordinary machine tool of the same specification, and the rigidity of the structure design is far higher than that of the ordinary machine tool. When ordering, the maximum value of process requirements, awesome torque, power, axial force and feed force can be checked according to the value supplied by the manufacturer. In order to obtain the high stiffness of machine tools, it is often not limited to the size of parts, but to choose the machine tool whose relative part size is larger than 1 ~ 2 specifications.
2、加工设备的加工精度
2. Machining accuracy of processing equipment
加工精度直接影响到产品的质量。当很多人否认你的机床精度不好时,会直接影响买家的决定。需要注意的是,加工精度和机床精度的概念是不同的。把制造厂样品或产品合格证的位置精度作为机床加工精度是错误的。样品或证书上标明的位置精度是机床本身的精度,而加工精度是整个工艺系统各种因素产生的误差之和,包括机床本身的允许误差。在选择类型时,可以参考过程能力kp的评价方法作为选择精度类型的依据。一般来说,计算结果应大于1.33。
Machining accuracy directly affects the quality of products. When many people deny that your machine tool accuracy is not good, it will directly affect the buyer's decision. It should be noted that the concepts of machining accuracy and machine tool accuracy are different. It is wrong to regard the position accuracy of sample or product certificate of manufacturer as machining accuracy of machine tool. The position accuracy indicated on the sample or certificate is the accuracy of the machine itself, while the machining accuracy is the sum of the errors caused by various factors in the whole process system, including the allowable error of the machine tool itself. When selecting the type, the evaluation method of process capability KP can be used as the basis for selecting precision type. Generally speaking, the calculation result should be greater than 1.33.


3、 加工设备数控系统的选择
3. Selection of CNC system for machining equipment
数控系统是加工中心运行的核心大脑。数控功能分为基本功能和选择功能。基本功能是不可避免的,只有当用户选择这些功能时,选择功能才会由制造商提供。数控系统的功能必须根据机床的性能要求来选择。在订货时,不应遗漏所需的全部功能,也应避免因利用率低而造成的浪费。我们还应该注意这些功能之间的相互关系。在可选的数控系统中,性能差别很大。应根据需要选择,不能片面追求高目标,以免造成浪费。选择多台机床时,应尽量选用同一厂家的数控系统,使操作、编程和维护更加方便。
CNC system is the core brain of machining center. CNC function is divided into basic function and selection function. Basic functions are inevitable, and only when the user selects these functions, the selection functions will be provided by the manufacturer. The function of the CNC system must be selected according to the performance requirements of the machine tool. When ordering, all the required functions should not be omitted, and waste caused by low utilization rate should also be avoided. We should also pay attention to the interrelationship between these functions. In the optional CNC system, the performance varies greatly. We should choose according to the needs and not pursue high goals unilaterally, so as to avoid waste. When selecting more than one machine tool, the same manufacturer's numerical control system should be selected as far as possible to make the operation, programming and maintenance more convenient.
4、坐标轴和联动轴的数量
4. Number of axes and linkage axes
坐标轴数和联动轴数应满足铝板加工的要求。坐标轴的数量也是机床等级的标志。一般来说,同一厂家、同一规格、同一精度的机床,加一个标准坐标轴,成本增加35%左右。虽然增加轴数可以增强机床的功能,但最后还是要注意工艺要求和资金平衡。
The number of coordinate axes and linkage axes should meet the requirements of aluminum plate processing. The number of axes is also a sign of the machine level. Generally speaking, the cost of a machine tool with the same manufacturer, specification and precision will increase by about 35% if a standard coordinate axis is added. Although increasing the number of shafts can enhance the function of the machine tool, it is still necessary to pay attention to the process requirements and capital balance.
5、自动换刀器和刀具储存容量
5. Automatic tool changer and tool storage capacity
动态换刀装置的选择主要考虑换刀的时间和可靠性。换刀时间短可以提高生产率,但换刀时间短。换刀装置结构复杂,故障率高,成本高。过分强调换刀时间会大大增加成本,提高故障率。据统计,加工中心约50%的故障与自动换刀装置有关。因此,在满足使用要求的前提下,应尽量选用可靠性高的自动换刀装置,以降低整机的故障率和成本。
The selection of dynamic tool change device mainly considers the time and reliability of tool change. Short tool change time can improve productivity, but tool change time is short. The tool changing device has complex structure, high failure rate and high cost. Overemphasizing the tool changing time will greatly increase the cost and increase the failure rate. According to statistics, about 50% of the failures in machining centers are related to the automatic tool changer. Therefore, in order to reduce the failure rate and cost of the whole machine, automatic tool changer with high reliability should be selected as far as possible under the premise of meeting the requirements of use.
自动换刀的质量和刀具库的容量将直接影响加工中心的性能和质量。刀具库容量的原则是满足复杂加工零件对刀具的需求。
The quality of automatic tool change and the capacity of tool library will directly affect the performance and quality of machining center. The principle of tool library capacity is to meet the needs of complex machining parts for cutting tools.
