How much does the Starrag Bumotec s230 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 Bumotec s230 is a very small two-spindle machine: the listed travels are 150 mm (5.9 in) in X, 150 mm (5.9 in) in Y and 123 mm (4.8 in) in Z, with a 375 mm U axis and a C axis that rotates continuously through 0-360°. The listed figures describe equipment for miniature parts, not a general-purpose mill.
The two spindles do very different jobs. The vertical spindle is listed at 45,000 RPM and 2 kW with ISO 10 tooling up to 7 mm in diameter, the speed range small end mills and drills need to reach a workable surface speed. The horizontal spindle is the opposite: 4,000 RPM, 1 kW and 1.1 Nm at 600 RPM, on an ISO 20 interface that takes tooling up to 300 mm in diameter. A tool that large on a spindle that slow is unusual for milling, so ask what the horizontal spindle was fitted with on the machine in question.
Tool capacity is modest. The magazine has 8 positions with automatic pneumatic loading, and jobs have to be planned around a short tool list. Lubrication is listed as microlubrication from a Vogel Lubrilean unit, and the table has no row for flood coolant.
The table also lists a vision system based on a Sony XCD-V60 camera (640x480 pixel), a precision of ±0.010 mm and a Siemens 840DI-SL control. The precision row does not say whether it refers to axis positioning or to the finished part, which is worth clarifying before relying on it.

Strengths & Limitations
Strengths
- Vertical spindle listed at 45,000 RPM and 2 kW for ISO 10 tooling up to 7 mm in diameter
- Second, horizontal spindle with an ISO 20 interface for tooling up to 300 mm in diameter
- Continuous 0-360° C axis and a 375 mm U axis alongside the X, Y and Z travels
- A vision system with a Sony XCD-V60 camera (640x480 pixel) is part of the listed equipment
- 8-position tool magazine with automatic pneumatic loading
Limitations
- Travels of 150 mm (5.9 in) in X and Y and 123 mm (4.8 in) in Z restrict the machine to miniature parts
- Only 8 tool positions, so parts with long tool lists need to be split or re-tooled
- The horizontal spindle is limited to 4,000 RPM and 1.1 Nm at 600 RPM
- Listed precision is ±0.010 mm, and the table does not say what measurement that refers to

Frequently Asked Questions
01
The listed travels are 150 mm (5.9 in) in X, 150 mm (5.9 in) in Y and 123 mm (4.8 in) in Z. A 375 mm U axis and a C axis with continuous 0-360° rotation are listed as well. These are small strokes, so check the part and its fixture against them before anything else.
02
Two. The vertical spindle is listed at 2 kW and 45,000 RPM with ISO 10 tooling up to 7 mm in diameter. The horizontal spindle is listed at 1 kW and 4,000 RPM, with 1.1 Nm at 600 RPM, and uses ISO 20 tooling up to 300 mm in diameter.
03
The tool magazine has 8 positions with automatic pneumatic loading. That is a small magazine, so a part needing more than 8 tools would require the magazine to be reloaded between operations.
04
The listed control is a Siemens 840DI-SL. Lubrication is listed as microlubrication from a Vogel Lubrilean unit, and the table has no row for flood coolant or through-spindle coolant. A Sony XCD-V60 camera (640x480 pixel) is listed as the vision system.
