The Ultimate Used CNC Machine Guide

November 10, 2021

If you're looking to buy a CNC machine, finding a used CNC can save you a lot of money, and it's typically the smarter, more cost-effective option.  However, there are a few crucial things to think about before making your purchase. Here's a simple guide to assist you with your decision-making when purchasing a used CNC machine.


It's a good idea to do some research about the CNC machine you're thinking about buying before you buy it. If you aren't capable of diagnosing problems on your own, you may end up paying too much money to keep your machine serviced and maintained. Alternatively, you can buy a used machine from a reliable seller who can give you assurances and expert service before you buy.


When purchasing an older, used CNC machine, make sure it has been updated to meet your requirements, or check if it can be upgraded at all. If you plan on doing complicated machining, you may need more advanced controls than the ones that come with the machine. Make sure to look into the availability of replacement parts and parts that can be upgraded.


The benefit of purchasing older equipment is that it helps you save a lot of money. The only thing matters are to buy a quality secondhand machine. Spend your time to explore online what models have stood the test of time and are best suited for your machine shop. You can also take the opinion of an experienced engineer who has worked with a wide range of machines in the past.

What to Consider When Buying a Used CNC Machine

Before purchasing a used CNC machine, you should think about a few things to ensure that it can meet all of your shop's requirements. Before you buy a used CNC machine, there are a few factors you should keep in mind.

  1. Tolerance

Tolerance refers to the acceptable deviation of a manufactured piece’s physical dimensions. External elements that can affect the CNC machine, such as humidity and temperature, cause this variance, which is a typical part of the manufacturing process. The significance of this is that the pipes become unusual if there is too much variance. Different CNC machines' tolerances, on the other hand, vary and are normally determined by the manufacturer.

2. Machine Hours

The machine may have 10,000 "power on hours" but few spindles or hours in motion. The machine hour rate is calculated by dividing a machine's total operating expenses during a certain time by the number of hours the machine is expected to work during that period. When purchasing a used CNC machine, one of the first things to consider is the number of hours the machine has logged.

3. Pricing

Pricing varies depending on the type, condition, and requirements. You can undoubtedly save money by purchasing used and receiving name-brand quality without breaking the bank, so do your research and look at average equipment life-spans.


Purchasing a used CNC machine might save you a lot of money, but you must be cautious and aware when doing so. When compared to purchasing a new one, you will need to conduct more study. You should compare machine listings and be aware of the differences between similar models, as well as examine specifications to ensure it has all of the capabilities you need. In addition to reading the documentation, you must properly inspect the machine and ensure that it passes the eye test.
