The vertical machining center (VMC) is one of the most versatile and useful tools in the shop. In fact, it can do things that a horizontal machining center (HMC) cannot. Here are some of the good things about VMC machines.
What Does a Vertical Machining Center Do?
A VMC utilizes computerized numeric control and is aligned in a vertical orientation. With HMC machines, the spindle is parallel with the floor. With VMC machines, the spindle (which contains the cutting tool) is in an “up and down” position. With both VMC and HMC, the cutter is located above the table and cuts over the top.
VMC Benefits
Visibility is one of the most important factors to consider when machining. When you use an HMC, the spindle is behind the tombstone and this can hinder vision. This is not the case with VMC machines. You enjoy more clearance and this makes it easier to perform milling tasks.
Cost
You’ll pay a lot more for a good HMC machine than VMC equipment. In fact, the average vertical machining center cost is more than three times less than an HMC machine. This is an important consideration if you plan to expand your business.
Experience
HMC machines are not used as much as their vertical counterparts. As a result, it’s harder to find qualified machinists to work with HMC equipment. In the long run, it’s cheaper and easier to go with a good VMC for your shop.
Size
Is space a big concern in your shop? An HMC is larger and heavier and needs more space than a VMC. For smaller shops, this is a problem.
Operating Costs
HMC tooling costs are greater (on average) than VMC. Fixtures and cutting tools usually cost more also. Programming HMC machines is a bit more complicated too. In total, the VMC offers many more good things than the HMC.
