What are the main factors that make up the price of a vertical machining center?

1. The numerical control system is an important factor in determining the price of a vertical machining center

The numerical control system is equivalent to a brain of the vertical machining center, and all the actions and programs of the machining center are completed by it. At present, the mainstream systems on the market are: foreign system brands, Japanese Mitsubishi, Japanese Fanuc (Fanuc), German Siemens, it should be noted that these systems are bundled with three-axis servo motors, that is, if your system is Mitsubishi , You must purchase Mitsubishi servo drives and motors;

Taiwan's system brands Taiwan New Generation, Taiwan Baoyuan, Taiwan systems can freely match other manufacturers' servo drives and servo motors, without restrictions; domestic system brands Guangshu, Huazhong CNC, Beijing Kanedi.

When choosing a numerical control system, you need to integrate many factors, such as the use environment, workpiece conditions, processing technology, procurement budget, etc. For example, when choosing a three-axis vertical machining mold, you can choose Fanuc0iMD-A or Mitsubishi M70-A. When processing products , You can choose Fanuc0iMD-B or Mitsubishi M70-B. It is recommended to choose Siemens 840D or Fanuc31i when choosing the five-axis vertical overtime system. If it is used for teaching, you can choose the five-axis of Huazhong or Guangshu. In occasions where processing requirements are not high and budgets are limited, domestic CNC systems or Taiwanese systems can be selected.

2. the tool magazine is the main factor that determines the vertical machining center

The high efficiency of the machining center lies not only in a sophisticated operating system, but also in a very important auxiliary function component. This is the tool magazine. The tool magazine is the container for the machining center to store the tools. The tool change time of the tool magazine depends on a machine tool. Efficiency plays an important role. The tool magazines commonly used in vertical machining centers include a hat-type tool magazine and a disc-type tool magazine. The disc-type tool magazine is also called a manipulator tool magazine or a knife-arm tool magazine.

3. the spindle unit is also very important

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. the price gap between hard rail and linear rail

The hard rail machine is slower, but has better rigidity and impact resistance. It is mainly used for heavy cutting and molds. The linear rail machine is fast and has better accuracy. It is mainly used for light cutting and products. Relatively speaking, there is no hard rail machine with a long life. Generally, BT40 has more bed rails, and BT50 has more rectangular rails. Many people now choose two-wire and one-hard when buying a vertical machining center, because this can increase the speed and increase the cutting power, and it is cost-effective.
