How much does the Tsugami B073C 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 B073C is a guide-bushless 7 mm (0.275 in) chucker: a 3-axis automatic lathe with a 15,000 RPM main spindle on a 1.1/1.5 kW (2 HP) motor, up to 21 tool positions and a FANUC 0i-TF control. Tsugami's current pages do not carry this table, so these are the listed figures and they have not been checked against the maker.
Running without a guide bushing changes what the machine is good at. The bar is gripped in the collet with nothing in front of it, so short parts come out with less remnant left on the bar, but long slender parts lose the support a bushing would give close to the tool. At 7 mm the work is small to begin with, and the B073C is aimed at short pieces within that size.
The table gives a single 32 m/min rapid traverse and only 3 axes, with no back spindle listed, so plan on features of the cut-off face needing a second operation unless the quoted machine shows otherwise. For comparison, the B073-VR runs 15,000 rpm (rated 12,000 rpm) on the same 1.1/1.5 kW, carries 13 tools as standard and weighs 1,350 kg (2,976 lb). No weight or dimensions are listed for the B073C, so ask for the installation drawing before preparing floor space.

Strengths & Limitations
Strengths
- 15,000 RPM main spindle for small diameters in bar up to 7 mm (0.275 in)
- Guide-bushless chucker layout leaves short remnants and suits short parts
- Up to 21 tool positions on a 3-axis machine
- FANUC 0i-TF control and a 32 m/min rapid traverse
Limitations
- No guide bushing, so long slender parts lack support close to the cutting tool
- Only 3 axes and no back spindle in the listed table, so cut-off face features likely need a second operation
- Main motor is 1.1/1.5 kW (2 HP), which keeps cuts light even in 7 mm bar

Frequently Asked Questions
01
No. The listed figures describe it as a dedicated chucker (guide-bushless). The bar is held in the collet without a bushing in front, which suits short parts and reduces remnant. For long slender parts that need support close to the tool, a guide-bushing machine is the safer choice.
02
Both are listed with a 15,000 RPM main spindle on 1.1/1.5 kW. The B073-VR has a rated speed of 12,000 rpm, carries 13 tools as standard and weighs 1,350 kg (2,976 lb). The B073C is listed with up to 21 tool positions, but its table has not been checked against Tsugami and gives no weight.
03
A FANUC 0i-TF control and a rapid traverse rate of 32 m/min. The table gives one rapid figure rather than a rate per axis, so ask for per-axis rates if a cycle time estimate depends on them.
