Process: Horizontal


The HCN-12500QS Horizontal Machining Center with quill head performs the operations of both a horizontal machining center and a traditional boring machine to significantly boost part-processing flexibility and reduce setups for improved overall throughput.

For stability, reliability and accuracy, the HCN-12500QS’s double-column design centers the quill to eliminate overhang or imbalance. Mazak’s double column also features a twin ball screw-driven Y axis that ensures fast, precise and smooth Y-axis stroke extension and retraction.


  • Quill-head features built-in motor, high-torque, direct-drive spindle for accurate machining for large workpieces
  • Linear drive guides
  • Angular contact bearings support Z-axis thrust for heavy-duty boring and drilling operations
  • Roller-type bearings provide stability during face milling and heavy roughing operations
  • Automatic tool changer available to further boost set up speeds
  • Optional automatic attachment changer increases parts processing flexibility through the use of various special operation attachments such as angled heads, U-axis boring tools and facing heads, U-axis OD turning heads and snout heads
