The most critical component of the machining center, if the CNC system is equivalent to the human brain, then the spindle is equivalent to the human heart. It can be seen that the spindle of the machining center is a very critical component. The machining center without the spindle is like a pile of scrap iron, and it is useless. Moreover, the spindle of the machining center has a high technical content. The spindle of the machining center is generally provided by professional manufacturers, and there are few machine tool manufacturers capable of producing the spindle. Today, the editor mainly introduces which transmission structure of the machining center spindle is suitable for heavy cutting.
Which transmission structure of machining center spindle is suitable for heavy cutting
As we all know, there are four kinds of main shaft transmission structure of the machining center, which are the four transmission structures of gear transmission spindle, belt transmission spindle, direct drive spindle and electric spindle. There are two types of transmission structure spindles that are suitable for heavy cutting occasions, namely gear transmission spindles and belt transmission spindles. These two transmission structure spindles are suitable for heavy cutting occasions, and have high flexibility in heavy cutting occasions. The following will introduce the characteristics and speed of these two spindles by the editor.
Characteristics and speed of gear drive spindle
Gear drive spindles are more popular in the early days of machine tools, and today’s machine tools rarely use gear drive spindles, because gear drive spindles have no protective measures under overload and slip conditions, and directly cause spindle wear in slip conditions, so CNC machine tools are very popular. Less configuration of gear drive spindle. The biggest characteristic of the gear drive spindle is its high rigidity, which is more suitable for heavy cutting applications. The speed of the main shaft of this type of transmission structure is generally about 6000r / min.
Characteristics and speed of belt drive spindle
The belt-driven spindle is widely used in machining centers. Because the belt-driven spindle can effectively protect the spindle from overload and slippage and avoid damage caused by the spindle slip, it is more suitable for processing in heavy cutting occasions, so it is favored by many machining centers. The belt drive spindle has the characteristics of simple structure, easy manufacture, simple installation, strong buffering capacity, etc. It is one of the most popular spindles at present. The speed of the main shaft of this type of transmission structure is generally around 8000r / min, and the highest can reach 12000r / min.
