The SINUMERIK 8 is a Siemens CNC control from the 1980s used to program and operate milling machines, machining centres and lathes. Siemens no longer builds this control generation in series, but it is still in daily service on many older machines. For clearly defined machining tasks, such a machine is often considerably cheaper than buying new.
The control is typically found on drilling and milling machines, machining centres and lathes from European builders of the 1980s and early 1990s. What matters is whether the number of axes, the equipment package and the existing NC programs fit your part range, and whether the documentation comes with the machine. Asset-Trade's free machine appraisal helps clarify in advance whether a specific machine suits your workpieces.
Inspect the control boards, check whether parameter sets and NC programs have been backed up, and confirm that the operating manual is included; SINUMERIK 8 spare parts now mostly come from dismantled machines or dealer stock. A test run under load plus a visual check of the electronics shows whether the control works reliably. Asset-Trade carries out a multi-stage inspection with functional tests, and you can view the machine on site and test it during a demonstration.
No blanket price can be given, because it depends on machine type, condition, tooling and the documentation supplied. Used machines typically sell for 40 to 70 percent less than a comparable new machine. After a free appraisal you receive a concrete calculation for the machine you are interested in.
A retrofit to a modern control can pay off if the mechanics, drives and spindle are in good condition; where wear is advanced, another used machine is often the more economical choice. Typical mistakes are buying without checking spare part availability, failing to back up programs and underestimating the learning curve. Asset-Trade's free machine appraisal helps you weigh the effort of a retrofit against the price of an alternative.
Asset-Trade handles worldwide shipping and export, including the required paperwork, and a dedicated project manager accompanies the entire process. The purchase follows a 7-step process from enquiry through inspection and testing to loading. Because operators experienced with the SINUMERIK 8 are now rare, plan enough time for training and for the handover of documentation.
