This type of equipment is very suitable for mass production and application scenarios that require high automation, flexibility and high-precision processing, such as automobile manufacturing, aerospace parts processing and other fields.

It is equipped with a dual-spindle system, a dual-station system, an automatic tool changing system, a CNC system, and a loading and unloading system, etc., and has a complete workpiece production chain. However, the existing equipment needs to assemble the turret and the tool seat in the preparation stage of use, and the tool seat is generally fixed to the turret surface by multiple bolts.
