What are the factors that affect machining center prices?

1. Machining Center Numerical control system

The numerical control system can be said to be the brain of the machining center. Any machining operation of the machining center cannot be separated from programming, and the numerical control system is also a relatively expensive part. At present, the commonly used CNC systems on the market are divided into two types, domestic and imported, and there are mainly these types.

The CNC systems of imported machining centers are commonly used FANCN, Mitsubishi, and Siemens. Imported machining center CNC system has the characteristics of stable and reliable performance, fast running speed, and strong data processing ability, which is suitable for processing more complex workpiece molds. However, the price is high, the operation interface is more complicated, and the requirements on the theoretical basis of CNC are higher.

Common CNC systems for domestic machining centers include Huazhong CNC, Kane, and Taiwan's new generation systems. The domestic CNC system has developed rapidly and has fully occupied the market. The domestic CNC system has the characteristics of friendly interface, convenient operation, and high-precision machining, and is the best choice for the pursuit of cost performance. In recent years, the domestic CNC center has been continuously developed and improved, and the five-axis linkage technology can be perfectly configured.

2. Machining Center The Tool Magazine

The tool magazine is equally important to the machining center, and all kinds of process processing are completed by the tool magazine. Tool magazines are generally divided into three types, disc type, hat type and chain type tool magazines. Vertical machining centers use disk type and hat type relatively more. Chain type is generally used for large machine tools, so we don’t do it here. Star detailed introduction. The hat type tool magazine is cheaper than the disc type, because the tool change speed is lower than that of the disc type. The disc type uses a mechanical arm to change the tool. Thanks to the manipulator, the disc-type tool magazine can complete automatic tool change in just a few seconds. According to your machining situation, you can choose the number of tools ranging from 16/24.

3. CNC Machining Center Spindle

The spindle unit is also an electric spindle, which determines the processing power of a machining center. The spindle speed is generally very high, all above 8000rpm/min, and the spindle speed above 10000rpm/min is a high-speed spindle. The machine tool will generate a lot of heat under high-speed processing, and the heat of high chipping will adhere to the machine tool table and workpiece. The surface will not only affect the machining accuracy of the workpiece, but also cause damage to the machine tool, so generally the spindle will be equipped with an oil-cooled or water-cooled cooling system. The most common transmission methods of spindles are belt transmission and direct transmission. Direct transmission is suitable for light cutting at high speeds, and direct transmission is generally selected for high-speed spindles.

4. Machining Center The Number Of Axes

Most of the machining centers are three-axis machining centers, and the X, Y, and Z three-axis linkage can meet most of the machining needs. However, there are also customers who add an additional rotary axis on the basis of the three-axis. Simply put, an indexing head is added on the basis of the three-axis, which becomes X, Y, Z, A or X, Y, A, B. . It can reduce benchmark conversion, improve processing accuracy, reduce the number of fixtures and floor space, shorten the production process chain, simplify production management, shorten the development cycle of new products, and the corresponding price is also much higher.
