Engineering a Production-Oriented VMC
Extended VMC cycle times due to modest spindle performance and slow non-cutting functions can increase costs for high-volume applications. However, new VMC offerings can minimize cycle times while maximizing competitiveness for production work.
Minimizing table overhang is one way this VMC can increase rigidity and machining accuracy.
Not all high-volume machining applications require HMCs. Many shops do well using lower-cost VMCs for production work. In some cases, though, a shop’s existing VMCs offer only modest spindle performance and relatively slow non-cutting functions, such as rapid traverse motions and tool changes. The resulting extended cycle times add up over long production runs, increasing overall manufacturing costs. That’s why Bill Howard, product line manager for Makino, says shops should leverage the latest VMC technologies engineered for high-volume production to minimize cycle times and maximize competitiveness.
