All the used horizontal machining centers for sale at CNCMachines.net have been thoroughly checked and refurbished as needed. We carry hundreds of machines all the time, so we can provide you with a great selection at consistent, fair prices.

By offering you a quality used horizontal machining center, we provide access to equipment and technology to keep you competitive and producing parts at high levels of efficiency. We’re here if you want to sell a used CNC and replace it with a different used HMC or if you want to find a used horizontal machining center for sale to increase production. We want to partner with you, so call us at 844.262.6789 and we’ll get started to find the best solutions for your shop. Our in-house service center ensures that quality used milling machines are ready to be put to work in your shop as soon as possible.

When selecting your HMC, you’ll want to take into consideration both your current and future needs for size, speed, versatility, power, and precision. Machines will vary by X, Y & Z travel, size taper, the number of axes (which determines part complexity), the spindle rpm (revolutions per minute), spindle motor power, and tool capacity, among other things. Take a look at all our current listings of horizontal machining centers ranging from 3-axis small CNC mills to 5-axis milling machines, and fast to heavy-duty RPM spindle speeds. We carry many brands including DMG/Mori Seiki, Doosan/Daewoo, Fadal, Ganesh, Haas, Hitachi Seiki, Hurco, Makino, Mazak, Milltronics, Okuma, Samsung, and OKK.

What is a Horizontal Milling Machine?

A Horizontal Machining Center (HMC) operates with its spindle in a horizontal position instead of a Vertical position like a VMC.  The CNC horizontal milling machine model allows constant loading and unloading of production work with 2 or more pallets.

Why Buy a Used Horizontal Machining Center Instead of a Used Vertical Machining Center?

One horizontal milling machine can be as productive as three vertical milling machines. The spindle utilization on an HMC can be has high as 85% compared to a typical 25% for a VMC. The horizontal machining center uses better chip evacuation methods when compared to vertical mills, which means less re-cutting and longer tool life. The surface finish from a horizontal mill machine is often better too. These machines are very sturdy and built to withstand vibrations, so the work environment is quieter, and the machine tends to last longer. Many owners believe that the additional initial investment in an HMC well-worth it since parts are less costly coming off the machine. Depending on the project, it might make sense to buy an inexpensive used HMC and use it exclusively for production. There is software available to help you program and run it to its full capacity.

Benefits of used horizontal machining centers include:

  • Higher production rate
  • Quieter running
  • Better surface finishes
  • Better chip management (chips fall away)
  • Better spindle utilization (more efficient)
  • Fewer operators (but they need to be well-trained)
  • Pallet change options available for automated loading/unloading

If you have access to the talent to run a horizontal machining center and associated programs (like CAD/CAM), consistent mid-to-high runs of parts and the capital to invest, a horizontal milling machine may be the best choice for you.

Why Buy a Used Horizontal Machining Center Instead of New One?

Most horizontal machining center machines are purchased for production and run 2-3 shifts daily for multiple years. When the product mix changes for a company, they may no longer need a particular HMC and need to sell it. A good quality new horizontal CNC machining center starts in the $100,000 range and can cost up to a million dollars, depending on brand and options. We see quality used CNC horizontal mills ranging from around forty thousand to a few hundred thousand dollars each. Like a car driven off the lot, a new CNC machine loses most of its book value as soon as it goes from “new” to “used” – but that is not a reflection of the number of miles (or parts) it is still capable of with good maintenance. Buying a used horizontal machining center can save you a lot of money without sacrificing production or features you need to optimize production.

Found a Used HMC that Looks Interesting? 

  1. Be informed. When you are shopping for a used horizontal machining center for sale, you’re going to need to do more research than when buying one new. Start by making a list of your requirements. You should consider the:
    • Types of materials you want to machine – Are the easy or hard to machine?
    • Tolerances you need – Tight tolerances or not?
    • Industries you’ll primarily be serving – How complex are the parts for this industry?
    • Level of production you’ll be running – High volume light-out? Or short runs?
    • Expertise you have available in your shop – Does anyone know the controls or have time to learn?

You may want to buy a similar HMC to one that you already have, or you may want to look for one that is newer, so you can begin to connect everything via ethernet or Wi-Fi to take advantage of software innovations. Consider the thru spindle coolant, tool eye management with a probe, full 4th axis and the tooling capability needed to meet your requirements.

  1. Ask for good photos. Zoom up in the photos and look for signs of damage and worn components.
  2. Speak with the manufacturer or distributor in the territory where that machine was (or is) operational. They may be familiar with the service provided on specific HMC’s in their own territory.
  3. Search similar horizontal machining centers for sale to see how pricing compares.
  4. Get the hours of operation.
  5. Ask for the maintenance records of the used HMC that you are considering. Repair work isn’t a bad thing. It will help you know what has been replaced, what hasn’t, and if it was done right. Ask for as much documentation as the seller can provide. This will help you if you have problems and provide you with details for buying parts.
  6. Find out what other tooling and accessories are for sale that could go with this used HMC.

Once you’ve done your homework, and you think you’ve finally identified the perfect used HMC for your company, it’s time to get it inspected. We require pre-inspection of all equipment by yourself or your representative before purchase. At CNCMachines.net, we offer options on how to ensure that the used CNC equipment you are buying meets your quality standards. Here are some inspection tips below.

How to Inspect a Used HMC for Sale On-Site

  1. Inspect for damage and worn components. Carefully look all over the machine. There are enough used HMC’s available that you shouldn’t have to buy a machine with obvious damage or signs of wear.
  2. Ask to operate the machine to see it actually run. Make some chips!
    • Listen to the sounds of the axis moving at different speeds
    • Run the spindle at the max RPM.
    • Look at the guards and sensors on the machine. If sensors, switches, wires and hoses all match and look like they match well, that’s an indication of a well-maintained machine.
    • Make parts on the machine if possible.
    • Check the tool-changer or turret. See how well it changes tools at different areas of the tool changer
    • Check the electrical cabinet for anything that looks like “not factory” and ask about it.

Buying the Machine?

  1. If you are planning on buying this machine, take a photo of the serial number plate which contains valuable information. Ask the seller to make a backup of the controller program while you are there. (This will make restoring easy if anything is lost when the machine is taken off power for transport.)
  2. Ask if the seller can provide the manuals that came with the machine.
  3. If possible, ask the owner why he’s selling the machine.
  4. Find out what process controller is on the machine. Have there been any upgrades?
  5. Review pallet changer options.
  6. Review chip & coolant management options.
  7. Find out the electrical requirements for install.
  8. Ask for all the manuals and other documentation for this machine.
