How much does the Starrag Droop+Rein TFS NEO Series cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Starrag. Configuration moves it a long way.
Overview
The Starrag Droop+Rein TFS NEO Series is a 5-axis portal machine whose head is the centre of the specification: a continuously controlled B axis, a C axis with ±400° of rotation, and spindle cartridges that are exchanged automatically. Spindle power is 40 kW and torque is up to 1,800 Nm (1,328 ft-lb).
The automatic cartridge exchange is what separates this machine from a portal with one fixed spindle. A part can be roughed with one cartridge and finished with a different one in the same clamping, without an operator rebuilding the head. Starrag's table states one power figure and an upper torque limit. It does not list the individual cartridges, their speeds or how many the machine can hold, so ask for the cartridge list when comparing quotations.
The ±400° C axis gives more than a full turn in each direction. In practice the head can follow a closed contour all the way round and still have margin before it must unwind. Together with the continuously controlled B axis, that suits parts with free-form surfaces. Travels, table size and tool capacity are not given in the published table.

Strengths & Limitations
Strengths
- Automatically exchangeable spindle cartridges, so roughing and finishing spindles can be swapped without manual work
- C axis with ±400° of rotation and a continuously controlled B axis
- Up to 1,800 Nm (1,328 ft-lb) of torque with 40 kW of spindle power
Limitations
- The table does not list the individual spindle cartridges or their speeds
- No travels, table size or tool capacity are published for the series
- 40 kW of spindle power sets the ceiling on metal removal rate

Frequently Asked Questions
01
Starrag lists the spindle cartridges as automatically exchangeable, meaning the machine can swap the spindle unit itself without manual intervention. The table gives 40 kW and up to 1,800 Nm (1,328 ft-lb) but does not itemise the cartridges, so ask which ones are included.
02
The C axis is listed at ±400°. The B axis is listed as continuously controlled, with no angular range stated in the table. Both are part of the machine's 5 continuous axes.
03
Spindle power is 40 kW and torque is up to 1,800 Nm (1,328 ft-lb). Because the torque is given as an upper limit and the cartridges are exchangeable, the figure belongs to the strongest cartridge and not to every one.
