At Surplex.com you will regularly find an extensive selection of high-quality used machinery at attractive prices. If you are looking for a CNC woodworking machine, we offer a range of machines, which are mostly in a good or excellent condition. Where possible, they will have undergone a functional test prior to being sold. If the used CNC machines exhibit defects, we will indicate this in the machine description.
Woodworking CNC machines are characterised by customisable programming options for movement procedures, which can be repeated and adapted as many times as needed by saving and changing the NC programmes. DIN 66025/ISO 6983 define a cross-system, manufacturer-independent interface for programming, which is supported by every woodworking CNC machine. More complex CNC machines for wood also feature additional or alternative programme interfaces, which make it easy to programme complicated movement processes.
There is a large range of CNC woodworking machines for sale at Surplex at low prices. We advise focussing on CNC machines made by established manufacturers whose CNC technology is known for quality and reliability even when second-hand. Popular CNC technology brands include BIESSE, CMS, HEIDENHAIN, HOMAG, MORBIDELLI, SINUMERIC and WEEKE.These and other prestigious manufacturers can be frequently found on our portal. If the machine you are looking for is currently unavailable, we advise taking a look another day since our marketplace is expanded nearly every day with new deals.

An additional interface automatically translates the programme entered by the operator into DIN code. This alternative interface, however, operates fully independently of this standard. Workpiece programming in a CNC machine for woodworking sets the control information for the production of a workpiece in a fixed form in a data memory device. In offline programming, the programme data is created as part of work preparation and is transferred to the machine via cables or on external data storage devices. In online/workshop programme, the programme is entered directly into the CNC technology. Workpiece programmes can be created using special manufacturing programming languages, such as APT and EXAPT, based on CAD data or construction drawings. Data-exchanging formats such as IGES are available for directly adopting data from CAD systems. The source text of the workpiece programmes is transposed into ‘cutter location data’ via the CLDATA interface, which contain datasets for positioning the workpiece to be used by the NC machine. These data sets can be translated into DIN code or are interpreted by the NC machine in real-time. Graphic environments allow NC programming at a very high abstraction level in workshop programming. It is also possible to directly control NC machines using an external control computer via a DNC interface (direct numerical control).

The area of “CNC woodworking machinery” encompasses all machinery featuring computerised numerical controls (CNC). Due to the extensive range of processing options, they are also called CNC wood processing centres. Since no hard-wired numerical controls have been offered since the beginning of the 1980s, the distinction between NC and CNC technology is only of historical interest and the terms are generally used synonymously.
The fastest and easiest tool rests to sharpen lathe tools. The the Right Angle the first time, every time.
More and more used woodworking machinery are CNC machines. Thanks to the Computerized Numerical Control, every work step of the machine is introduced as numeric codes, which the computer transforms into control signals. Some advantages of CNC technology are its accuracy, constant production quality and high unit numbers, what also applies to used machines. At Surplex you will find the whole spectrum of used CNC machining centres, edgebanders, saws and many more. Make sure that you get your used CNC machining centre -whether horizontal or vertical- from BIESSE, MORBIDELLI, HOMAG and other leading manufacturers!

Extensive automation has also taken place in the field of woodworking. As a result, a large range of used CNC woodworking machines has become available for processing wood using CNC technologies. The advantages of second-hand CNC machines is that they can often be purchased at far lower price and are immediately available, in contrast to new machinery. The choice to whether to buy second-hand should depend on the intended type of CNC woodworking machine. CNC machines with extensive electronics and numerous moving parts will be more prone to needing repairs or replacements of parts. If the used CNC machine has been properly maintained and wear parts have been frequently replaced, there is no reason to be wary of purchasing second-hand.

Question Is the type of oil dictated by the oil delivery systems or the type of rack/rail used? Are there any specific lubricants to CNC machines that are better than what you find from an auto parts store? Forum Responses (CNC Forum) From contributor C: Yes there are. We use a Mobil EPO on our auto systems for the Rovers. From contributor D: Huge difference. I don't know specifically what automotive lubricant that you are referring to, but general purpose auto grease has solids in it. This grease will harden and clog the small grease delivery lines on a CNC and it is a huge pain to get them clear. I know, I learned the hard way by allowing a production manager to talk me into saving a few bucks. The Mobil Lux epo that BVC sells is a zero weight grease with no solids and will not harden over time. Mobil doesn't sell it in a grease gun insert because it will run out. From Contributor B: Im interested to know how to go about unclogging the oil tubes, I have some blockages. From contributor D: Unplugging is tuff. The lines are too long to push out old grease in one piece. I got connectors for the grease lines and cut them at in the middle. I then set up the grease gun so I could connect it directly to the line with a push connection. You cant get a seal using just the zirc fittings. This connection gives you a sealed connection and you can slowly push the old grease out. Go very slow or the line will burst (wisdom learned). To help expedite the process I hit bearing blocks and other spots of known blockage with a heat gun to soften grease. Be patient as it takes a while. When done we reconnected the lines we cut with inline push connectors. From Contributor B: Your response came just in time as I have the tech from SCM coming tomorrow! While we are on the subject, I have a manual central lubrication system that works with a pump lever. Before I bought the machine (NBM from SCM) I was told the only difference between automatic and manual lubrication is the pump lever. I had no idea that I would have to guess/estimate the 8 hours of running time between lubrications. 50 for the main spindle, 20 hours for the tool holders, 6 months for the drill bank, and so on. To my disbelief and disappointment, the guys from SCM say there is no internal timer on this wonderful computerized machine that counts running time! If there's anyone reading this and looking to buy a new machine, this piece of information is valuable! Either get auto lube, or at least there should be a built in callout for lubrication, for every item that requires it. I am going to find out if it is possible to switch the system to auto.
CNC machines are an enhanced version of NC machines. The technology was devised at MIT in the early 1950s for use in production technology. It replaced the cabled, logical links of NC technology with fully customisable computers and pushed the older technology completely out of the market within around five years. While in the case of pure NC technology, the control information was read directly from a perforated strip, CNC technology only uses such external storage media for data transmission or archiving. CNC programmes are loaded onto an internal memory within the machine for execution, or are directly stored there.
What are CNC machines used for? Today, CNC technologies are included in all stationary machine tools and these form the basis of fully-automated production. The field of woodworking has also seen the introduction of CNC machining centres, which can be used to enable efficient mass production.
