Used CNC Router for Sale: Getting the Best Deal on Pre-Owned Equipment

Buying a used CNC router for sale is similar to purchasing a used car. The equipment is complex, and the buyer must correctly evaluate its condition, otherwise he or she could end up buying a lemon. The buyer must also be careful from whom he or she buys the equipment, as it could determine whether the machinery has been inspected, reconditioned, and tested, or merely purchased and listed for sale. If you need used CNC woodworking machines that perform “like new,” the tips below will help you find a great deal on topnotch, pre-owned equipment.

Check the X, Y, and Z axes. Holding them in one’s hand and moving them is a good way to check the axes of the router. By keeping one’s hand on the casting while the machine is in rapid mode at fifty percent, one can tell whether the axes make a smooth transition. The axes, as well as the ballscrew, should also be checked for oscillation while the machine is in a stopped position.

In addition to feeling for problems with the machinery, you can also listen for problems as the equipment operates. A low growling sound while the machine is in rapid mode at fifty percent could signal problems with the bearings or ballscrew. A high-pitched humming noise could indicate a problem with the servomotors.

Examine the spindle. The spindle of CNC woodworking machines should be examined by operating it at different Revolutions Per Minute (RPMs). You can start out at 50 RPM and work your way up to the max. While listening for noises that indicate mechanical problems, try to operate the spindle at a time when the warehouse is relatively quiet.

Examine ways or linear guides. As you examine the ways or linear guides, check to see if they are grooved, discolored, or pitted. If they are, this could indicate that the turkite has worn away, or the machine has not been properly lubricated. Removing the axis is the best way to see if the turkite is gone.

Do a pallet change and tool change. As you perform a pallet change and tool change, listen for abnormal noises. Also, look at the fingers on the tool changers to see if they show signs of wear or exhibit alignment problems. A used CNC router for sale with these problems will probably need repairs sooner than later.

Assess the reputation of the seller. You can evaluate a seller in several ways. Particularly, you should focus on choosing a seller who has the following characteristics:

  • Has a warehouse and reconditioning facility
  • Reconditions equipment prior to reselling it
  • Has a professional business website
  • Has an outstanding record at the Better Business Bureau (BBB)
  • Has strong professional references

A seller that has these attributes typically sells excellent machinery, and does not mind prospective buyers inspecting and testing the machinery before they buy it.
