Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Starrag. Configuration moves it a long way.

Overview

The Starrag Bumotec s191H is a compact mill-turn machine for bar work: 7 CNC axes, a bar capacity of 32 mm (1.26 in) and travels of 200 mm (7.87 in) in X, 160 mm (6.30 in) in Y and 250 mm (9.84 in) in Z. The listed figures describe a machine sized for small, detailed parts taken complete from bar stock, not for large envelopes or heavy stock removal.

The milling spindle is listed at 40,000 rpm and 12.5 kW (16.8 hp). That pairing points to small cutters, engraving and fine finishing passes rather than large-diameter roughing, which a 32 mm (1.26 in) bar seldom calls for anyway. The turning spindle runs to 6,000 rpm and carries the C axis, and the B axis is continuous, so angled and contoured features can be milled in the same clamping as the turned diameters.

Tool capacity is 90 positions, a large magazine for an envelope this small. It leaves room for sister tools and for more than one part family to stay loaded, which is what long runs from bar need. Positioning accuracy is listed at ±0.002 mm (±0.00008 in) and repeatability at ±0.001 mm (±0.00004 in).

Size is the main thing separating it from the Bumotec s191V, which is listed with 400 mm (15.7 in) of X, 200 mm (7.9 in) of Y and 410 mm (16.1 in) of Z and a 50 mm (1.97 in) bar capacity. The s191H weighs 5,500 kg (12,125 lb), so the floor and the route into the building need checking despite the short travels.

Strengths & Limitations

Strengths

40,000 rpm milling spindle rated 12.5 kW (16.8 hp), suited to small cutters and fine finishing in bar-sized parts
90 tool positions, enough to keep sister tools and several part families loaded for long runs from bar
Continuous B axis and a C axis on the turning spindle, within 7 CNC axes, allow angled milling in the same clamping as turning
Listed positioning accuracy of ±0.002 mm (±0.00008 in) and repeatability of ±0.001 mm (±0.00004 in)

Limitations

Bar capacity is 32 mm (1.26 in); the Bumotec s191V is listed at 50 mm (1.97 in)
Travels of 200 mm (7.87 in) in X, 160 mm (6.30 in) in Y and 250 mm (9.84 in) in Z rule out anything beyond small parts
The 12.5 kW (16.8 hp) milling spindle is built for speed, so heavy roughing with large cutters is outside its range
The listed figures give no rapid traverse rate, spindle taper or turning spindle power, so these must be confirmed before ordering

Best For

Small complex parts machined complete from bar up to 32 mm (1.26 in) Fine milling and engraving with small tools at up to 40,000 rpm Angled and contoured features using the continuous B axis and the C axis Long bar-fed runs that need many tools loaded, up to 90 positions

Frequently Asked Questions

01 What bar size does the Bumotec s191H take?

The listed bar capacity is 32 mm (1.26 in). Parts that need larger stock fall outside this machine. The Bumotec s191V is listed with a 50 mm (1.97 in) bar capacity, and the Bumotec 191neo with Ø 42/50/65 mm.

02 How fast and how powerful are the spindles?

The milling spindle is listed at 40,000 rpm with 12.5 kW (16.8 hp). The turning spindle is listed at 6,000 rpm and has a C axis. The listed figures give no torque for either spindle and no power for the turning spindle, so ask for those if the work involves heavy turning cuts.

03 How does the s191H differ from the Bumotec s191V?

The s191H is the smaller machine on the listed figures. Its travels are 200 mm (7.87 in) in X, 160 mm (6.30 in) in Y and 250 mm (9.84 in) in Z with a 32 mm (1.26 in) bar capacity. The Bumotec s191V is listed with 400 mm (15.7 in), 200 mm (7.9 in) and 410 mm (16.1 in) of travel and a 50 mm (1.97 in) bar capacity. The s191V offers 30, 60, or 90 tool positions, where the s191H is listed with 90.

04 How many tools and axes does the s191H have?

The listed figures give 90 tool positions and 7 CNC axes, including a continuous B axis and a C axis on the turning spindle. With that many tools on a 32 mm (1.26 in) bar machine, duplicate tools for wear and the tooling for several different parts can stay in the magazine at once.

05 How heavy is the Bumotec s191H?

The listed machine weight is 5,500 kg (12,125 lb). That is more than the 5,000 kg (11,023 lb) listed for the Bumotec s181, so check floor loading and rigging access even though the travels are short.
