Vertical of Horizontal machine tool – what to choose for better options?

As a machine shop operator, you might wonder whether you should opt for a vertical machining centre or a horizontal machining centre. Here's a few facts that might help your decision-making process. Here are some benefits of using a horizontal machining centre:

Horizontal machine centre:

HMCs really stand out on spindle run time. Compare 25% on a VMC (vertical machining centre) to 85% on an HMC. This translates into a simple fact - An HMC will create the same part, and use 1/3 less labour doing so. HMCs costs significantly more than a vertical machining centre, but they can do the same amount of work as 3 VMCs. Gravity aids chip evacuation, meaning a more refined surface finish and a longer tool life. HMCs also have a fourth axis tombstone capacity.

Vertical machining centre:

VMCs are considerably cheaper than HMCs (horizontal machining centres) - According to the Association for manufacturing Technology, it costs approximately $120,000 for an average VMC, compared to $380,000 for the average HMC. It's no wonder that 4 times as many machine shops purchase VMCs every year. It's easier to see what's going on inside a VMC. HMCs are built with the spindle behind the tombstone, which makes seeing what's happening much harder.

Many more machinists, shop owners and operators have experience with VMCs, plus a VMC will require less floor space.

A short contrast between the two:

To sum up - VMCs are better if your shop is new, your funds for investment are tight, and if you're working with small quantities and you change jobs frequently. HMCs are best for shops that have investment capital, and can afford to spend more on skills and upgraded tooling to produce parts in volume.
