Tsugami SS26

The Tsugami SS26 is a 26 mm (1.02 in) Swiss-type lathe and the middle size of the SS line. Its main spindle is rated 3.7 / 5.5 kW (5 / 7.4 hp) and turns 200 - 10,000 rpm, as does the sub spindle, and the six axes run under a FANUC 32i-B. Tsugami America lists 24/40 tool stations, 10/13 of which take live tools.

With the guide bushing the machine turns up to 270 mm (10.62 in) per chucking; in chucker mode it manages 50 mm (1.97 in). The larger bar over the SS20 is matched by a stronger spindle: 3.7 / 5.5 kW against the SS20's 2.2 / 3.7 kW (3 / 5 hp), so the heavier turning passes that a larger diameter calls for are better supported, while the 10,000 rpm top speed is kept.

Compared with the SS32 on the same frame, the SS26 gives up bar capacity but keeps chucker mode, which the SS32 does not offer, and runs its spindles to 10,000 rpm against the SS32's 200 - 8,000 rpm. For parts that fit within 26 mm, or for short chucker work at this size, that makes the SS26 the more flexible of the two.

Live tools are listed at 5,000 rpm, a limit for small drills and cutters. The SS267-III offers 38 tools as standard at 4,000 kg (8,818 lb) for heavier milling content at this bar size. The SS26 itself weighs 3,400 kg (7,495 lb) and needs 2,020 × 1,675 × 2,020 mm (79.5 × 65.9 × 79.5 in).
