Product Description

SMALL size range for parts: 200MM~800MM, tailored for precision engineering tasks.
Introducing the CNC Double Ends Facing Centering Drilling Milling Center Machine, crafted for unparalleled precision and efficiency.

Featuring a state-of-the-art 3 moving axis design coupled with a self-centering fixture, ensuring optimal alignment and accuracy.
Achieve complete processing with our innovative one-time clamping mechanism, streamlining operations and boosting productivity.

The Double-End Centering Machine is a specialized CNC marvel, expertly crafted to process the end face and center hole of shaft parts. With the capability to clamp once and execute milling, drilling, tapping, chamfering, and more on both ends simultaneously, this machine significantly enhances processing efficiency and precision.
Our multi-spindle centering machines come in three distinct bed designs: flat, inclined, and vertical. Choose from single head, double head, or multi-head configurations to perfectly match your production needs.


Double-head centering machines are indispensable in the automotive, motorcycle, motor, pump valve, agricultural, and construction machinery industries. They flawlessly process components like half shafts, cams, and E-bolts with unmatched precision.


Equipped with versatile milling, drilling, and threading spindles, both ends of the machine handle chamfering and end cylindrical turning. Utilize identical or varied spindles on both ends to perform simultaneous or sequential operations, embodying a multifunctional spindle combination CNC machine tool.
