Overview
The Tsugami P034 is a 4-axis CNC precision automatic lathe with back spindle capability, designed for complete front-and-back machining of micro parts up to 3 mm (0.118 in) diameter. It's the most popular configuration in the P0 series for production shops, because the 3 mm capacity covers the majority of micro connector pins, watch stems, and contact probes, while the back spindle eliminates secondary operations.
Both the main and back spindles run at 20,000 RPM with a 0.75/1.1 kW (1/1.5 HP) motor on the main side. That spindle speed is well-matched to the 3 mm diameter range — you'll get surface speeds of roughly 190 m/min at full RPM on a 3 mm part, which is right in the sweet spot for brass and aluminum. The 14 tool positions on the gang tool post give you dedicated stations for both front-side and back-side operations without having to compromise on either.
The P034 shares the same compact platform as the rest of the P0 family: 1,770 x 820 x 1,600 mm (69.7 x 32.3 x 63.0 in) in a 0.8 m² footprint. Weight comes in at 1,050 kg (2,315 lb). The air-regulated chuck gripping system on both spindles provides precise, numerically adjustable clamping force — essential for preventing deformation of small-diameter parts during transfer between spindles.
For shops producing complete micro parts that need backworking, the P034 is the go-to model in the P0 lineup. It handles everything from simple back-facing and cutoff cleanup to back-drilling and back-threading. The rapid traverse at 20 m/min keeps cycle times competitive, and the gang-type tool post means zero turret indexing delay between operations.

Strengths & Limitations
Strengths
- 20,000 RPM back spindle enables complete front-and-back machining of 3 mm micro parts in one cycle
- 14 tool positions provide enough stations for complex multi-operation parts with both front and back tools
- 3 mm capacity covers the bulk of connector pin, watch part, and contact probe production
- Ultra-compact 0.8 m² footprint fits multiple machines in a small production area
- Air-regulated dual spindle gripping prevents part damage during transfer and backworking
- Gang tool post eliminates turret indexing time for faster overall cycle times
Limitations
- 3 mm max diameter limits the machine to dedicated micro-part applications only
- No Y-axis means no off-centerline milling — cross-holes and flats require different approaches
- 0.75/1.1 kW spindle motor limits material removal rate on harder materials like stainless steel
- 14 tool positions may still be tight for very complex parts requiring 10+ different tools

Frequently Asked Questions
01
The P034 adds a back spindle (20,000 RPM) and a 4th axis, bumping tool capacity from 11 to 14 positions. Weight increases from 1,000 kg to 1,050 kg. The P034 costs roughly 15-25% more than the P033. If any of your parts need backworking, the P034 is the clear choice. The P033 is better only for high-speed front-side-only production where you want the simplest possible setup.
02
The P034 is purpose-built for extreme micro work. Its 20,000 RPM spindles, 0.8 m² footprint, and air-regulated gripping are all optimized for parts under 3 mm. A conventional Swiss lathe like the B0125 offers more flexibility (12 mm capacity, Y-axis, more tools) but takes up more space, costs more, and isn't as fast at pure micro production. If 90%+ of your work is under 3 mm, the P034 is more productive.
03
Yes, but with some limitations. The 0.75/1.1 kW spindle motor is designed primarily for brass, aluminum, and precious metals. Stainless steel (303, 304, 316) is feasible at 3 mm diameter — the cutting forces are small at this scale. You'll need to reduce speeds and use appropriate coated carbide or PCD tooling. Cycle times will be longer than with free-machining materials. For high-volume stainless micro work, make sure to test cycle times before committing.
04
Tsugami doesn't publish the specific control for the P0 series separately, but based on the P036W (a related P-series model), these machines typically run on FANUC 0i-TF Plus controls. This is a well-supported, industry-standard control that most CNC programmers and operators will be familiar with.
05
Most P034 production cells run with one operator overseeing 3-6 machines. The machines are designed for unattended production once set up — load the bar feeder, verify the first article, and let it run. The compact 0.8 m² footprint means all machines in the cell are within easy reach. Operator intervention is mainly for bar stock changes, tool wear compensation, and periodic quality checks.
