In this content collection, we look at the fundamentals of milling machines and walk the reader through the considerations that must be made when purchasing a VMC. How does the frame impact repeatability? What is the relationship between spindle speed, torque and horsepower? What chip-removal strategies will you employ? Buying the VMC that suits your needs depends on the answers to these questions.
The vertical machining center (VMC) is the workhorse of modern CNC machining. Just about every job shop relies on a fleet of them for milling, drilling, boring, tapping and myriad other operations that go into producing metal parts. The versatility of the basic design can vary from a simple three-axis mill to a five-axis machining center with a high-speed spindle and simple pallet attachment, enabling VMCs to accurately machine a wide variety of parts at a variety of production levels.
