Selling your Reiden RX18: Reiden’s largest center, rare and in demand
The RX18 is the largest 5-axis machining center in Reiden’s current line — built for workpieces that need a table format up to ø1,800 × 1,400 mm and pallet loads up to 4,000 kg. On the used market, an RX18 rarely appears: Reiden builds in low volume, and owners typically keep the machine until the plant closes.
Anyone parting with an RX18 sells to a small but well-funded buyer base — large moldmakers, aerospace suppliers, shops handling heavy single parts. The rarity supports price: when a well-maintained RX18 reaches the market, demand generally outpaces supply.
Specifications (manufacturer data)
| Feature | Value | Note |
|---|---|---|
| Travel (X/Y/Z) | 2,200 / 2,200 / 1,610 mm | A-axis ±105°, C-axis 360° (5-axis simultaneous machining) |
| Table load / workpiece size | Rotary table ø1,800 × 1,400 mm, max. 4,000 kg pallet load | largest table format in the RX line |
| Spindle (speed/power) | 14,000 rpm, 94/113 kW (standard version) | DDT spindle variants available as an option |
| Tool magazine | 92 / 144 / 264 / 371 positions (standard options) | larger magazines for series and complete machining |
| Control | Heidenhain TNC7 or Siemens Sinumerik One (current series) | older traded machines mostly carry Heidenhain TNC 640 |
| Weight | approx. 52,000 kg | heaviest machine in the RX line |
Price assessment (as of October 2026)
For the Reiden RX18 we have no reliable public price range: used Reiden machines are hardly ever advertised publicly with a price, and we currently have no listing with a price for the RX18. Value is set by control version, build year, tool magazine, spindle condition and maintenance history. The methodology behind our valuations: What is my CNC machine worth?
What determines your RX18’s price
- Control: current RX18 units run Heidenhain TNC7 or Siemens Sinumerik One; traded used machines mostly carry the proven TNC 640 — both versions are in demand, with TNC7 tending to command higher prices.
- Spindle hours and condition: a current runout log for the 14,000 rpm spindle is the strongest selling point on a machine in this price class.
- Tool magazine: from 92 to 371 positions — a generously equipped magazine widens the buyer pool to series and complete machining.
- Maintenance history and geometry records: a documented axis measurement to ISO 230-1 supports the valuation.
- Duty profile: an RX18 from moldmaking or aerospace running one or two shifts achieves better prices than a machine from continuous three-shift series production.
Typical buyers of an RX18
The RX18 is sought mainly by large moldmakers, aerospace suppliers and shops handling heavy single parts who need Reiden’s precision even at large table loads — for example tool and fixture builders for the automotive industry or machinists working structural components.

How the sale works
The process follows our Reiden acquisition: model, build year, control, spindle hours and photos are enough for the first assessment. After that: offer, payment before pickup; we organise disassembly and transport. Details: How it works.
