How much does the Starrag Heckert T55 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 Heckert T55 is a 5-axis mill-turn machining center with pallet change: a 15,000 RPM, 100 kW spindle for milling and a rotary table that runs at 900 RPM in turning mode. Starrag lists 292 Nm (215 ft-lb) of spindle torque, a tool store of up to 450 tools and a pallet change time of 12.5 seconds.
Mill-turn on a pallet machine means the workpiece is spun by the table while a static tool in the spindle cuts it. At 900 RPM the table can generate useful turning speeds, so bores, seats and sealing faces can be turned concentric to the milled features without moving the part to a lathe. For housings and round parts with milled detail, that removes a setup and the alignment error that comes with it.
The spindle figures point two ways. 100 kW is a high power rating and 15,000 RPM makes the spindle usable in aluminum, while 292 Nm (215 ft-lb) is moderate, so the power is reached at speed and not in low-rpm roughing. Starrag's table does not name the tool interface, and it gives no travels or pallet size. The table load row says only that high loading masses are possible, without a number.
Three rows concern production use. The 12.5 second pallet change keeps non-cutting time short on small batches. The 13-channel hydraulics allow fixtures with several separately controlled clamping circuits on the pallet. And the thermo-symmetric design is credited with 38% less floor space than conventional alternatives, a comparison Starrag does not define further.

Strengths & Limitations
Strengths
- Milling and turning on one machine: a 15,000 RPM spindle plus a rotary table at 900 RPM in turning mode
- 100 kW of spindle power with 292 Nm (215 ft-lb) of torque
- Tool store of up to 450 tools
- Pallet change in 12.5 seconds
- 13-channel hydraulics for fixture clamping
- Thermo-symmetric design that Starrag says takes 38% less floor space than conventional alternatives
Limitations
- Spindle torque of 292 Nm (215 ft-lb) is moderate against 100 kW of power, so heavy low-speed roughing is not its strength
- Starrag's table gives no travels, pallet size or tool interface for the T55
- Table load is described only as high loading masses, with no figure to check a fixture and part against
- The 38% floor-space saving is measured against conventional alternatives that are not specified

Frequently Asked Questions
01
Yes. Starrag lists it with 5 axes for simultaneous mill-turn work, and the rotary table runs at 900 RPM in turning mode. Milling is done with a 15,000 RPM spindle rated 100 kW and 292 Nm (215 ft-lb).
02
12.5 seconds in Starrag's table. The table does not list the pallet size or the number of pallets, so confirm both, along with any pallet storage, if the machine is to run in a cell.
03
Up to 450 tools. That is the upper limit of the tool store; smaller magazine sizes and the tool interface are not listed in the published table, so check the configuration and the maximum tool dimensions with Starrag.
04
They are listed under clamping. Thirteen hydraulic channels allow a fixture to have several separately switched clamping circuits, for example to release and re-clamp a part in sequence during machining. The table gives no pressure figure.
05
Starrag's page states high loading masses without giving a number. Travels and pallet dimensions are also missing from the table, so the weight and size of part the machine accepts has to be confirmed directly before planning work for it.
