The SINUMERIK 850 is an older Siemens CNC control generation found mainly on milling and turning machines. It handles axis interpolation and feed control as well as the management of part programs and tool data. Used machines with this control can be requested through Asset-Trade subject to availability.
All axes should be tested under power, and the drive units, measuring systems and stored machine parameters and programs should be checked and backed up. Asset-Trade carries out a multi-stage inspection with functional tests and offers an on-site inspection and demonstration. The condition of the control hardware, backup batteries and peripherals should be documented.
The price depends mainly on machine type, size, condition and tooling, so there is no flat figure. Used industrial machines typically cost 40–70% less than comparable new machines. Asset-Trade provides a free machine appraisal so you can judge a quoted price realistically.
The key factors are part geometry, the axes and tools you need, and whether documentation and existing programs come with the machine. A dedicated project manager reviews your requirements and proposes suitable machines. The 7-step purchase process clarifies technical fit, price and logistics step by step.
A retrofit is technically possible but depends heavily on the condition of the drives, motors and measuring systems. As long as spare parts and documentation are available, continued operation with the existing control is often the more economical option. Comparing with a newer used machine that already has a more current control is a useful alternative.
Asset-Trade handles worldwide shipping and export, including loading and the required documentation. An on-site inspection and demonstration can be arranged before purchase, and handover can be coordinated with operator briefing on site. A dedicated project manager accompanies the whole process from quotation to delivery.
