Experience unparalleled precision with our large size CNC double ends facing centering CNC Drilling Milling Center machine, designed to revolutionize the efficiency of your production line.
Our innovative 4-axis design features a self-centering fixture, enabling one-time clamping to seamlessly complete complex processing tasks with unmatched precision.
The double-end centering machine is a specialized CNC machine tool that precisely processes the end face and center hole of shaft parts. It offers the advantage of single-time clamping to efficiently perform milling, drilling, tapping, chamfering, and more on both ends of the workpiece, significantly enhancing processing accuracy and throughput.
Our multi-spindle centering machines are available in three distinct types: flat bed, inclined bed, and vertical, tailored to your specific needs. Depending on spindle count, choose from single head, double head, or multi-head configurations to optimize your workflow.

Double-head centering machines are quintessential for shaft part processing across various industries including automotive, motorcycles, motors, pump valves, and agricultural & construction machinery. Utilize them to process components such as half shafts, cams, and E-bolts with precision milling.

Our advanced machine features dual-end simultaneous processing using milling, drilling, and threading spindles, with additional capabilities for chamfering and end cylindrical turning. Employ spindles with the same or varied functionalities at each end for versatile, multifunctional CNC machining.
