Overview

The Tsugami B0126C is a dedicated guide-bushless (chucker) Swiss-type CNC lathe with 6-axis capability and 12 mm (0.5 in) bar capacity. The 'C' designation tells you everything you need to know about its intent: this is a purpose-built chucker machine optimized for shorter parts where a guide bushing isn't necessary, eliminating the material waste associated with remnant lengths in traditional Swiss-type operation.

Under the covers, the B0126C shares its DNA with the B0126-III series. You get a 12,000 RPM main spindle and matching 12,000 RPM sub-spindle for back-working operations, driven by a 1.5/2.2 kW spindle motor. The 6-axis configuration adds a Y2-axis on the sub-spindle side, which is a real advantage when you're doing complex back-end milling, off-center drilling, or hex profiling. Live tooling runs at 8,000 RPM across up to 8 live tool positions, with 25 total tool stations available. That's a lot of capability packed into one setup.

The FANUC 32i-B control handles the 6-axis coordination, and the machine's rapid traverse rate of 32 m/min keeps non-cutting time to a minimum. At 1,750 kg (3,858 lbs), the B0126C is a compact machine with dimensions of 1,655 x 1,125 x 1,700 mm (65 x 44 x 67 in), making it a reasonable fit for shops running multiple machines in a tight layout.

The value proposition here is straightforward: if you're making parts with a low length-to-diameter ratio from 12mm bar stock, the B0126C saves you money on material while still delivering Swiss-level precision and surface finish. You won't need ground bar stock either, which cuts your material costs further. For medical components, electronic connectors, and automotive sensor housings that don't require the guide bushing's support, this is a smart, cost-effective choice.

Strengths & Limitations

Strengths

Dedicated chucker design eliminates guide bushing remnant waste, reducing material costs by 10-15% on short parts
6-axis configuration with Y2 on sub-spindle enables complex back-end milling and off-center features in a single setup
25 tool positions with 8 live stations at 8,000 RPM handle cross-drilling, milling, and threading without secondary ops
12,000 RPM main and sub-spindle speeds are well-suited for small-diameter brass, aluminum, and stainless parts
FANUC 32i-B control provides smooth 6-axis interpolation and supports advanced programming features
Compact 1,750 kg footprint fits easily into multi-machine Swiss cell layouts

Limitations

No guide bushing means parts with high L/D ratios (above 3:1) won't achieve the same concentricity as guide bushing models
12mm bar capacity limits this to small parts only; shops needing 20mm+ should look at the B0205 or S205 series
1.5/2.2 kW spindle motor is modest for aggressive roughing on tougher materials like titanium or Inconel
Dedicated chucker design can't be converted to guide bushing operation if job mix changes

Best For

Medical device manufacturers producing short implant components, ferrules, and fittings from 12mm bar stock Electronics and connector producers making pins, contacts, and housings with low L/D ratios at high volumes Automotive sensor and fuel system component shops needing Swiss precision on short parts without guide bushing waste Contract manufacturers looking to reduce material costs on high-volume short-part production runs Shops transitioning from conventional CNC lathes to Swiss-type production for short, complex parts

Frequently Asked Questions

01 What's the difference between the B0126C and the B0126-III?

The key difference is the guide bushing. The B0126-III has a convertible guide bushing that can run in Swiss mode or chucker mode. The B0126C is a dedicated chucker -- it's optimized exclusively for guide-bushless operation. This makes the B0126C simpler to set up for short parts and eliminates the guide bushing maintenance, but you lose the ability to machine long, slender parts that benefit from guide bushing support.

02 What parts are best suited for the B0126C vs. a guide bushing machine?

The B0126C excels on parts with a length-to-diameter ratio below about 3:1. Think short pins, bushings, ferrules, connector housings, and valve components. If your parts are longer than roughly 36mm on a 12mm diameter, you'll likely get better concentricity and surface finish from a guide bushing model like the B0125 or B0126-III.

03 Does the B0126C require ground bar stock?

No. One advantage of the dedicated chucker design is that it doesn't require ground bar stock, which can save 20-40% on material costs compared to guide bushing machines that typically need precision-ground bars. Cold-drawn bar stock works fine, which is a meaningful cost reduction on high-volume jobs.

04 How does the Y2-axis on the sub-spindle help?

The Y2-axis lets you perform off-center drilling, milling, and contouring on the back side of the part while it's held in the sub-spindle. Without Y2, you're limited to on-center operations for back-working. With it, you can produce flats, hex profiles, cross-holes, and other features that would otherwise require a secondary operation.

05 What's the expected price range for a B0126C?

New B0126C machines typically fall in the $180,000-$260,000 range depending on tooling configuration and options. The chucker design is generally priced slightly below the convertible B0126-III since it omits the guide bushing system. Used units are less common since the C-series is a newer addition to the lineup.
