   由于鋁板加工中心設備遠比普通機床昂貴,所以受到的制約因素更多,機床選擇合理與否就更顯重要。正確選型是用好加工中心、使加工中心設備發揮效益的關鍵。在購買鋁板加工中心設備時,認真考察這五大要點尤為重要:
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、加工設備的剛度 鋁板生產廠家
1. Rigidity of processing equipment
由于加工中心設備的剛度直接影響機床的生產效率和加工精度,所以加工中心的加工速度遠高于普通機床,電機的功率也高于普通機床同一規格的普通機床,其結構設計的剛度遠高于普通機床。訂貨時,可根據制造廠提供的數值,校核工藝要求、允許扭矩、功率、軸向力和進給力的最大值。為了獲得機床的高剛度,往往不局限于零件尺寸,而是選擇相對零件尺寸大于1~2規格的機床。
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、加工設備的加工精度
2. Machining accuracy of processing equipment
加工精度直接影響到產品的質量。當很多人否認你的機床精度不好時,會直接影響買家的決定。需要注意的是,加工精度和機床精度的概念是不同的。把制造廠樣品或產品合格證的位置精度作為機床加工精度是錯誤的。樣品或證書上標明的位置精度是機床本身的精度,而加工精度是整個工藝系統各種因素產生的誤差之和,包括機床本身的允許誤差。在選擇類型時,可以參考過程能力kp的評價方法作為選擇精度類型的依據。一般來說,計算結果應大于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、 加工設備數控系統的選擇
3. Selection of CNC system for machining equipment
數控系統是加工中心運行的核心大腦。數控功能分為基本功能和選擇功能?;竟δ苁遣豢杀苊獾?,只有當用戶選擇這些功能時,選擇功能才會由制造商提供。數控系統的功能必須根據機床的性能要求來選擇。在訂貨時,不應遺漏所需的全部功能,也應避免因利用率低而造成的浪費。我們還應該注意這些功能之間的相互關系。在可選的數控系統中,性能差別很大。應根據需要選擇,不能片面追求高目標,以免造成浪費。選擇多臺機床時,應盡量選用同一廠家的數控系統,使操作、編程和維護更加方便。
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、坐標軸和聯動軸的數量
4. Number of axes and linkage axes
坐標軸數和聯動軸數應滿足鋁板加工的要求。坐標軸的數量也是機床等級的標志。一般來說,同一廠家、同一規格、同一精度的機床,加一個標準坐標軸,成本增加35%左右。雖然增加軸數可以增強機床的功能,但最后還是要注意工藝要求和資金平衡。
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、自動換刀器和刀具儲存容量
5. Automatic tool changer and tool storage capacity
動態換刀裝置的選擇主要考慮換刀的時間和可靠性。換刀時間短可以提高生產率,但換刀時間短。換刀裝置結構復雜,故障率高,成本高。過分強調換刀時間會大大增加成本,提高故障率。據統計,加工中心約50%的故障與自動換刀裝置有關。因此,在滿足使用要求的前提下,應盡量選用可靠性高的自動換刀裝置,以降低整機的故障率和成本。
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.
自動換刀的質量和刀具庫的容量將直接影響加工中心的性能和質量。刀具庫容量的原則是滿足復雜加工零件對刀具的需求。
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.
