F85B/F86B Series Five-Face Machining Milling Head

F85B/F86B Series Five-Face Machining Milling Head

Descriptions

The Gong Yang F85B/F86B Five-Face Machining Milling Head is engineered to deliver comprehensive 5-face multi-axis cutting performance on heavy-duty CNC double-column plano-millers and 5-face machining centers, providing seamless dual-spindle capability for both vertical and horizontal milling to maximize machine versatility. Utilizing an ultra-rigid hydraulic curvic coupling indexing mechanism, the horizontal spindle can rotate a full 360° to precisely orient cutting angles. When integrated with the machine spindle motor’s 4th-axis positioning capability, the head executes fully automated angular indexing without manual intervention, substantially slashing setup cycles and eliminating cumulative tolerances across heavy, complex workpieces.

Engineered for dependable torsional strength, rigid torque transmission, and extended operational durability under heavy duty cycles, both the drive gearing and dual spindle shafts are precision-machined from high-grade chromium-molybdenum alloy steel, rigorously carburized, heat-treated, and precision ground. Both the vertical and horizontal spindles incorporate hydraulic tool unclamping systems accommodating standard BT50 tooling for rapid and repeatable tool seating, with options to integrate spindle electrical control encoders for closed-loop orientation. Delivering up to 38 KW of drive power and 1200 N.m of cutting torque with a 1:1 drive reduction ratio at speeds up to 2000 RPM, the F85 supports large tool diameters up to ψ200 mm. Operating strictly with clockwise (forward) rotation for cutting—reverse rotation is dedicated exclusively to rigid tapping and counterboring operations and must never be applied to milling or drilling—the F85 guarantees uncompromising geometric precision, structural rigidity, and long-term production reliability.

Features

  • The five-face milling head can be used for vertical milling and horizontal milling. While horizontal milling, the spindle can rotate 360 degree. It can help one machine multi purpose.
  • The five-face milling head is positioning of hydraulic curved teeth. While horizontal milling, the spindle can rotate 360 degree and adjust the angle to select the milling direction of the milling cutter. And can automatically adjust the angle without manual adjustment. (Need to match the function of the fourth axis of the spindle motor.)
  • The main shaft and gears are made of chromium-molybdenum alloy steel and subjected to special carburizing treatment to ensure durability.
  • The reduction ratio of the five-face milling head is 1:1.
  • This milling head is only suitable for tapping and column pit processing operations during reverse processing, and cannot be used for cutting and drilling operations to avoid mechanical damage.
  • The lock and retract tool of the vertical and horizontal axis of the milling head adopts hydraulic pressure control, and the tool holder adopts BT specification which is quickly positioned.
  • It can be used with the spindle electric control encoder, please purchase when ordering the milling head.
