DECM series high-speed crankshaft external milling machine is an internationally advanced external follow-up high-speed milling machine tool to introduce and absorb foreign advanced follow-up milling technology, using modular, flexible and standardized methods. Through the independently controlled dual-power main shaft, X-axis, Z-axis and high-precision disc cutter, the precision milling of the machined parts (crankshaft, camshaft, etc.) can be completed with high efficiency.
