What are the transmission structures? Then, what kind of transmission structure is selected for the vertical machining center? Is the spindle suitable for heavy cutting?
Gear drive spindle
What are the main shaft of transmission structure of machining center
There are four types of main shaft drive structure in machining center, which are gear drive spindle, belt drive spindle, direct drive spindle and motorized spindle. These four types of transmission structure spindle have their own advantages and are suitable for different cutting field. In the market, the vertical machining center generally adopts the belt drive spindle, which is one of the mainstream spindle structures configured on the vertical machining center; the gear driven spindle is rarely used in the machining center at present, because the overload and slipping of the gear drive spindle will directly cause the wear and tear of the spindle, and the maintenance is very difficult and the maintenance price is expensive, so it is very difficult Few machining centers use gear driven spindles; direct coupled spindles and motorized spindles are generally used in high-speed machining centers. The speed of direct coupled spindles and motorized spindles is very fast, generally more than 12000r / min. for example, belt driven spindle and gear driven spindle are several or more times faster.
Belt drive spindle
What kind of transmission structure should the vertical machining center choose? The spindle is suitable for heavy cutting
In general, the main shaft of transmission structure suitable for heavy cutting occasions includes belt drive spindle and gear drive spindle. These two transmission structure spindles are suitable for heavy cutting occasions, especially belt drive spindle. The belt drive spindle can effectively protect the spindle in case of overload and sliding wear, and the most used spindle in vertical machining center is belt drive Spindle, belt drive spindle is also widely used in machining center. However, the use of gear drive spindle in vertical machining center is less, the reason has just been said, here will not repeat.
