How much does the Tsugami B038-III cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Tsugami. Configuration moves it a long way.
Overview
The Tsugami B038-III is a 38 mm (1.5 in) Swiss-type lathe with 6 axes and a 7.5/11 kW main motor, built for large-diameter bar and parts with heavy cross work. The listed figures give a main spindle of 200-6,000 RPM, a sub-spindle of 200-7,000 RPM, 32/42 tool positions with 15/26 of them live at 6,000 RPM, and a FANUC 32i-B control. The table has not been checked against Tsugami's current pages.
The axis row names X1, Y1, Z1, X2, Y2 and Z2, plus C1 and C2 for spindle indexing. Both tool groups therefore have their own Y travel, and both spindles can be positioned for milling and drilling off centre. Combined with up to 26 live positions, that makes this a machine for parts that need as much milling as turning.
The guide bushing is convertible: with it the headstock strokes 320 mm (12.6 in), without it 70 mm (2.75 in). The low top speed follows from the bar size, since a 38 mm bar reaches its cutting speed at far fewer revolutions than small stock, and the 7.5/11 kW motor supplies the torque for heavy roughing. Rapids are 32 m/min.
The B038M in the same bar size takes a different route: 7,000 rpm (rated 5,000 rpm) on 3.7/5.5 kW, 40 tools, and 7,100 kg (15,653 lb). The B038T runs a FANUC 31i-B with live tools at 200 - 8,000 rpm and weighs 6,200 kg (13,669 lb). The B038-III is listed at 4,850 kg (10,694 lbs) and 2,240 x 1,515 x 2,050 mm (88 x 60 x 81 in).

Strengths & Limitations
Strengths
- 7.5/11 kW main motor for heavy roughing in 38 mm (1.5 in) bar
- 6 linear axes with Y on both tool groups, plus C1 and C2 spindle indexing
- Up to 15/26 live positions out of 32/42 tool positions for milling-heavy parts
- Convertible guide bushing: 320 mm (12.6 in) stroke on the bushing, 70 mm (2.75 in) without
- Sub-spindle runs to 200-7,000 RPM, a little faster than the main spindle
Limitations
- Main spindle stops at 200-6,000 RPM, slow for small features on a large part
- Live tools run to 6,000 RPM, against 200 - 8,000 rpm on the B038T
- Listed at 4,850 kg (10,694 lbs), so floor loading and rigging need planning
- Without the guide bushing the stroke is only 70 mm (2.75 in)

Frequently Asked Questions
01
Six linear axes: X1, Y1, Z1 on one tool group and X2, Y2, Z2 on the other. The table also lists C1 and C2, the indexing axes of the main and sub-spindles. Y on both groups lets off-centre milling and drilling run on either side of the part.
02
The B038M runs to 7,000 rpm (rated 5,000 rpm) on a 3.7/5.5 kW motor, carries 40 tools and weighs 7,100 kg (15,653 lb). The B038-III is listed with a 7.5/11 kW main motor at 200-6,000 RPM, 32/42 tool positions and 4,850 kg (10,694 lbs). Pick on the balance of spindle power against tool count.
03
With the guide bushing the headstock stroke is 320 mm (12.6 in). Converted to run without it, the stroke is 70 mm (2.75 in). Long shafts belong on the bushing; short, stubby parts can run guide-bushless to leave a shorter remnant on each bar.
04
The main spindle runs 200-6,000 RPM on 7.5/11 kW and the sub-spindle 200-7,000 RPM, with live tools to 6,000 RPM. These are low speeds by Swiss-type standards because the machine is sized for 38 mm (1.5 in) bar, where cutting speed is reached at fewer revolutions.
