First, the rigidity of the machining center Because the rigidity of the machining center will directly affect the production efficiency and the machining accuracy of the machine tool, the processing speed of the machining center is much higher than that of the ordinary machine tool, and the motor power is also higher than that of an ordinary machine tool of the same specification, so its structural design stiffness It is also much higher than ordinary machine tools. The order can be checked according to the process requirements, allowable torque, power, axial force, and maximum feed force, based on the values ​​provided by the manufacturer. In order to obtain the high rigidity of the machine tool, it is often not limited to the part size, but a machine tool with a relative part size of 1 to 2 sizes is selected.
Second, the machining center processing precision machining accuracy, a direct impact on the quality of your products, many people in the negation of your machine tool accuracy is not, it will directly affect the purchaser's decision. It should be noted that machining accuracy and machine accuracy are two different concepts. It is wrong to regard the positional accuracy on the manufacturer's sample or on the product certificate as the machining accuracy of the machine tool. The accuracy of the position marked on the sample or certificate is the accuracy of the machine tool itself, and the machining accuracy is the sum of the errors generated by various factors of the entire process system, including the error allowed by the machine tool itself. In the selection process, the evaluation method of the process capability kp can be used as the selection basis for accuracy. In general, the calculation should be greater than 1.33.
Third, the selection of numerical control system CNC machining system, is the core of the operation of the processing center, CNC functions are divided into basic functions and selection functions. Basic functions are necessarily provided, and the selection function is provided only when the user selects these functions. The function of the numerical control system must be selected according to the performance requirements of the machine tool. When ordering, the required functions must be completely reserved and cannot be omitted. At the same time, the use rate is not high to cause waste, and attention must be paid to the correlation between the functions. In the optional numerical control system, performance varies greatly. Should choose according to need, can not pursue one-sided high index, so as to avoid causing waste. When multiple machine types are selected, the same manufacturer's numerical control system should be used as much as possible so that operation, programming, and maintenance are convenient.
Four, the number of coordinate axes and the number of linkage axes The number of coordinate axes and the number of linkage axes should meet the typical workpiece processing requirements. The number of coordinate axes is also a sign of the machine tool grade. Under normal circumstances, with a factory, the same specification, the same accuracy of the machine, adding a standard axis, the cost increases by about 35%. Although increasing the number of axes can enhance the function of the machine tool, it is ultimately necessary to pay attention to the process requirements and the balance of funds.
Fifth, the automatic tool change device and the magazine capacity The automatic tool change device choice mainly considers the tool change time and the reliability. Shorter tool change time can increase productivity, but tool change time is short. The general tool changer has a complex structure, high failure rate, and high cost. Excessive emphasis on tool change time can greatly increase the cost and increase the failure rate. According to statistics, about 50% of the faults in the machining center are related to the automatic tool changer. Therefore, under the premise of satisfying the use requirements, a highly reliable automatic tool changer should be selected as far as possible to reduce the failure rate and the overall cost.
The working quality of the automatic tool change and the magazine capacity will directly affect the performance and quality of the machining center. The magazine capacity is based on the principle that a complex machining part needs the tool.

What points do you need to pay attention to when purchasing a machining center?
Because the machining center is far more expensive than an ordinary machine tool, it is subject to more restrictive factors, and the choice of machine tools is even more important. Correct selection is the key to making good use of the machining center and making the machining center effective. When purchasing a processing center, it is particularly important to carefully examine these five major points:
