CNC vertical machine centers are drilling and milling machines that are programmed by a computer to perform tasks with the utmost accuracy and precision.

The machine center has an automatic tool changer and it uses rotary cutters to remove material from workpieces. The spindle is oriented vertically so tools are cut from the top of workpieces.

CNC vertical machine centers enable large parts to be machined on all sides without the need for an operator. And with CNC technology, vertical machine centers now have the capability to perform at very high speeds.

They also have ancillary equipment available, including rotary indexes that enable four-axis or five-axis machining, quick-change work holding devices, angle heads, and spindle speeders.

There is no doubt that CNC vertical machine centers are ideal for performing a variety of milling and drilling tasks. And the good news is, the machinery does not have to cost the earth.

You will find plenty of used CNC vertical machine centers for sale. But before you go ahead and purchase one, you need to know what to look for. Get started by checking out the following helpful guide.

Shop Around to Find the Best Price

CNC vertical machine centers are less expensive than horizontal ones, and you can find a less expensive vertical machine center by looking at ones for sale in the second-hand market.

By shopping around, you will be able to find machine centers at various price points and potentially get a great deal. Start your search by checking out this collection of second-hand machines.

While price is a significant factor to consider when buying a used CNC vertical machine center, it should not be your only criterion. Make sure you consider the other factors in this guide alongside the price to find the best machine center for you.

Go with a Reputable Seller

It may sound obvious, but you need to ensure you buy your used CNC vertical machine center from a reputable seller.

Make sure the vendor has all the proper accompanying paperwork and details before you complete a transaction. That includes the machine’s service record.

You also need to inspect the machine in person or virtually to make sure it is in full working order and in good condition.

If you are unable to see it in person and are viewing it online, make sure you can view detailed video footage of the machine. Going by a photograph and description alone is not recommended unless you go with a highly reputable vendor who can provide a guarantee.

Regardless, make sure you get hold of the machine’s service record. And if any red flags are raised during your communication with the vendor, find a more reputable seller.

Size Considerations

Vertical machine centers are available in different sizes, so you need to determine how much space you have available before you begin your search for a second-hand machine.

Make sure you know the dimensions of any machine you are considering purchasing before you buy.

You also need to determine the strokes required for machining. You can then anticipate the manufacturing and dimensions of parts. Take the three linear axes of X, Y, and Z into account, to come up with accurate calculations.

Speed Considerations

You also need to consider your speed requirements. The speed you need depends on the materials you will be machining. You can machine a wide variety of materials with CNC vertical machine centers, including but not limited to aluminum, steel, cast iron, plastic, wood, and glass.

Basically, when machining materials that have low rigidity, you will need high rotation speeds, particularly for performing finishing tasks. Harder materials require lower speeds.

So, know what materials you will use to determine what speed capabilities you need your CNC vertical machine center to have.

And speaking of speed, when it comes to efficiency, you need to consider whether you want your vertical machine center to have a pallet loader or not. A machine center with a pallet loader shortens part cycle times and facilitates unattended operations.

Look for the Best Model for Your Needs

Once you have determined things like the materials you will be using with your CNC vertical machine center and the speed and size requirements, you need to consider different models.

Look for models by leading brands like Haas, Mazak, Okuma, and Doosan, to ensure the machines are of high quality.

Research specific makes and models too so that you can find out the exact specs and determine which brands and models are best suited to your needs.

Models that have stood the test of time are always a good option because you know they are reliable. Alternatively, more recent machines could have the features you are looking for.

If you are not an expert, it is a good idea to get an experienced engineer who has worked with CNC vertical machine centers to help you find the right machine.

Consider Upgrading Old Models

If you are considering buying an older model of a CNC vertical machine center, you need to ensure it has all of the capabilities you require or the potential to be upgraded.

For instance, if you are planning to use the machine for performing complex machining tasks, you may need more advanced controls than the controls included with the original machine.

If you are considering buying a CNC vertical machine center to upgrade it, you must first research the availability of replacement parts and upgradeable components.

You also need to consider what the costs will be for buying a used machine center and upgrading it compared to the price of buying one that already comes with the controls you need.

In Summary

Ultimately, finding the right CNC vertical machine center comes down to first determining your machining needs.

When you know things like the materials you will be using, the parts you will be making, your speed requirements, and the space you have available, you will be prepared to begin the buying process.

Research specific models and compare brands, too, and make sure you go with a reputable seller.

The key is paying attention to detail. When you know what to look for, you will be able to much more easily find the ideal used CNC vertical machine center.
