Overview
The Tsugami B020M-III is a 20 mm (0.79 in) Swiss-type lathe built around a swivelling tool spindle. That spindle runs to 25,000 rpm (rated 20,000 rpm), tilts through -10° to 185° on a B axis that positions in 0.001° steps, and draws on 30 tools held in Capto C3 shanks. The point of the layout is to put compound-angle drilling and milling on the machine that turns the part, instead of on a mill after the part is cut off.
Both work spindles are small, fast units. The main spindle reaches 10,000 rpm (rated 8,000 rpm) on 3.7/5.5 kW, and the sub spindle goes higher, to 12,000 rpm (rated 8,000 rpm), on 2.2/3.7 kW. The tool spindle carries the same 2.2/3.7 kW rating as the sub spindle. Those speeds keep surface speed up on diameters of a few millimetres; the power ratings say the machine is meant for many light, accurate cuts rather than for heavy stock removal.
Seven axes appear in the rapid traverse row: X2 and Z2 at 35 m/min, A1 at 32 m/min, X1 and Z1 at 30 m/min, Y2 at 24 m/min and Y1 at 20 m/min. The 1 and 2 suffixes point to two separate axis groups, each with its own X, Y and Z, which is the arrangement that lets front and back work overlap in the cycle.
The frame is big for the bar size. Tsugami lists a footprint of 2,500 × 1,905 × 1,920 mm (98.4 × 75.0 × 75.6 in) and a weight of 5,300 kg (11,684 lb), so floor loading and access deserve a check before delivery. The spec table gives no machining length per chucking and names no control, so both need confirming with Tsugami against the parts you plan to run.

Strengths & Limitations
Strengths
- B-axis tool spindle swivels from -10° to 185° with 0.001° positioning, so angled holes and faces are cut in the same setup
- Tool spindle runs to 25,000 rpm (rated 20,000 rpm), which suits small drills and end mills
- Holds 30 tools on Capto C3 shanks
- Sub spindle reaches 12,000 rpm (rated 8,000 rpm), above the 10,000 rpm of the main spindle, for back-end work on small diameters
- Rapids of 35 m/min on X2 and Z2 and 30 m/min on X1 and Z1 keep non-cutting time short
Limitations
- Capacity stops at a 20 mm (0.79 in) machining diameter
- Main spindle power is 3.7/5.5 kW and tool spindle power 2.2/3.7 kW, which limits heavy roughing and large drills
- At 5,300 kg (11,684 lb) and 2,500 × 1,905 mm of floor area it is a heavy, large machine for 20 mm work
- The table gives no machining length per chucking, so long slender parts need checking with Tsugami first

Frequently Asked Questions
01
It swivels the tool spindle from -10° to 185°, positioned in 0.001° increments. With that spindle running to 25,000 rpm (rated 20,000 rpm), the machine can drill and mill at compound angles while the part is still held, rather than sending it to a mill for a second operation.
02
The listed maximum machining diameter is 20 mm (0.79 in). The table does not give a machining length per chucking or a separate through-spindle figure, so confirm both with Tsugami against the longest part you intend to run.
03
The table lists a tool capacity of 30, with Capto C3 as the tool shank. Capto is a polygon-taper holder system, so tools can be preset in their holders away from the machine before a job change.
04
Main spindle: 10,000 rpm (rated 8,000 rpm) on 3.7/5.5 kW. Sub spindle: 12,000 rpm (rated 8,000 rpm) on 2.2/3.7 kW. Tool spindle: 25,000 rpm (rated 20,000 rpm) on 2.2/3.7 kW. The speeds favour small diameters and small cutters; the power ratings favour light cuts.
05
Tsugami lists the footprint as 2,500 × 1,905 × 1,920 mm (98.4 × 75.0 × 75.6 in) and the weight as 5,300 kg (11,684 lb). Add room for bar loading and chip handling around that envelope, and check the floor before the machine arrives.
