The price of machinery and equipment has been a concern of enterprises. Vertical machining centers can complete milling, boring, drilling, tapping and cutting threads and other processes have received many enterprises. In fact, whether it is imported processing center, Taiwan processing center or domestic processing center, as far as the processing center itself is concerned, even if the same brand, the same model of vertical processing center, the different configuration of the price is different. So what are the reasons that affect its price?

First, numerical control system
The numerical control system is equivalent to a brain of the vertical machining center, and all the actions and procedures of the machining center are completed by it. In the selection of numerical control system, need to integrate a variety of factors, such as the use of the environment, workpiece conditions, processing technology, procurement budget. In the processing requirements are not high, the budget is limited, can choose the domestic numerical control system or Taiwan system.

Second, the knife library
The high efficiency of the machining center is not only a fine operating system, but also a very important auxiliary functional components, this is the tool library, the tool library is the processing center to store the tool container, the tool library tool change time plays an important role in the efficiency of a machine tool. Vertical machining center often used knife library has a hat type knife library and disk type knife library, disk type knife library is also called manipulator knife library or knife arm type knife library.

Three, spindle unit
The spindle speed is generally very high, above 8000rpm/min, and above 10000rpm/min is a high-speed spindle. The machine tool will produce a lot of heat under the processing of high speed, and the heat of high chip attached to the table and workpiece surface will not only affect the machining accuracy of the workpiece, but also cause damage to the machine tool. So the general spindle will be equipped with oil cooled or water cooled cooling system. The common driving mode of spindle is belt drive and direct drive. Direct drive is suitable for medium and light cutting in high speed, and direct type is generally selected for high speed spindle.

Four, hard rail and line rail price gap
Hard rail machine speed slower, but better rigidity, collision resistance, mainly used for heavy cutting, die. Line rail machine speed, better accuracy, mainly used for light cutting, product, relatively no hard rail machine long life. Generally, the BT40 bed has more linear rails, and the BT50 bed has more rectangular rails. Now many people buy vertical machining centers will choose two lines and a hard, because this can not only improve the speed and increase the cutting effort, high cost performance.
