CNCM7 CNC Crankshaft External Milling Machine program enables simultaneous machining of two connecting rod journals or main journals, including step milling, step arc milling, journal arc milling, and external diameter milling, while controlling axial position dimensions. Through tooling and machine tool component adjustments or switching, this machine allows for flexible machining of various crankshaft series, meeting the technological requirements of crankshaft processes. Except for manual loading and unloading, all other milling work cycles are fully automated, completing the milling of different crankshaft types.
1) Manual positioning and loading/unloading are required. The operator only needs to place the crankshaft on the clamping support blocks; the remaining positioning, clamping, and machining work is completed automatically by the equipment.
2) Maximum crankshaft length: 7000mm
3) Maximum crankshaft rotation diameter: Approximately 760mm
4) Maximum crank radius: 220mm
5) Cutter head diameter: Approximately Φ1500mm
6) Cutter head linear speed: 120～180m/min (adjustable via frequency converter)
7) Maximum workpiece diameter for clamping: φ100~Φ320mm (positioning fixture)
