The FK14160D series CNC dividing head is one of the essential accessories for CNC milling machines, CNC boring machines, machining centers, and other CNC machine tools. It can also be used as the main accessory for semi-automatic precision milling machines, boring machines, or other machine tools. Paired with servo motors or single coordinate CNC systems, it can complete any angle or continuous indexing work of a rotary coordinate. It can be directly connected to the CNC system of the CNC machine tool, adding a linked rotary coordinate axis to the CNC machine tool, greatly improving the range and performance of the machine tool. This series of CNC dividing heads adopts a combined worm gear structure, which reduces the deformation of the worm gear caused by pneumatic braking and improves product accuracy; Adopting a dual lead worm gear pair makes it easy to adjust the meshing clearance, which is beneficial for maintaining accuracy; The main shaft system adopts two pairs of high-precision tapered roller bearings, which have high precision and small volume.
