Overview

The Tsugami M06SY-II is the full-featured flagship of the 6-inch M-series lineup, stacking a sub-spindle, Y-axis, and live tooling into a single turret lathe platform. It's the machine you choose when you want to drop parts complete with turning, off-center milling, cross-drilling, and back-end operations all handled in one uninterrupted cycle.

The machine handles 260 mm (10.24 in) chuck work and 51 mm (2 in) bar stock. Both main and back spindles run 200-4,500 RPM with a 7.5/11 kW (10/14.8 HP) main motor. The 12-station turret accepts live tooling, and the Y-axis provides ±50 mm of cross travel for off-center features. Rapid traverse hits 24 m/min on X, 12 m/min on Y, 27 m/min on Z, and 30 m/min on the sub-spindle A-axis.

At 5,600 kg and 2,470 x 1,850 x 1,930 mm, the M06SY-II is the heaviest and tallest machine in the M06 family. That mass isn't wasted -- it provides the foundation for stable milling operations with the Y-axis engaged, where off-center cutting forces would cause problems on lighter machines.

The M06SY-II represents Tsugami's most complete answer for shops that want true mill-turn capability with back-working on a compact turret lathe. Bolt circles, eccentric features, cross-holes, and back-end turning all happen without the part leaving the machine. For parts that currently touch three different machines, this consolidates everything into one.

Strengths & Limitations

Strengths

Sub-spindle, Y-axis, and live tooling provide the most complete part machining capability in the M06 lineup
±50 mm Y-axis enables bolt circles, eccentric holes, and off-center milling in addition to standard operations
12-station turret with live tooling handles complex multi-feature part cycles
5,600 kg machine weight provides exceptional stability during off-center milling operations
Parts that previously required three machines can be completed in a single setup
Both spindles at 4,500 RPM with C-axis enable precise angular features on front and back ends

Limitations

Most expensive variant in the M06 family, requiring consistent use of all features to justify the cost
12-station turret shared across two spindles and live tools can feel cramped on very complex parts
Y-axis rapid traverse at 12 m/min adds cycle time on programs with heavy Y-axis movement
Machine complexity requires skilled programmers and maintenance personnel
Live tooling milling power is still limited compared to dedicated mill-turn centers

Best For

Complete part manufacturers producing components with turning, off-center milling, and back-end features Valve and pump manufacturers making bodies with bolt patterns, ports, and precision turned bores Aerospace fitting producers requiring tight-tolerance mill-turn parts with features on both ends Medical device shops machining complex surgical instruments and implant components Shops consolidating multi-machine processes to reduce WIP and improve feature accuracy High-mix production cells where the versatility to handle diverse part geometries is critical

Frequently Asked Questions

01 Is the M06SY-II worth the premium over the M06SD-II?

Only if your parts need off-center features. The M06SD-II handles centerline milling and sub-spindle back-working just fine. The M06SY-II adds ±50 mm Y-axis travel for bolt circles, eccentric holes, and off-center flats. That's a significant capability addition, but it comes at a cost premium of roughly $20,000-$30,000. Evaluate your specific parts to determine if the Y-axis eliminates enough secondary operations to justify the investment.

02 How many operations can the M06SY-II realistically replace?

For typical mill-turn parts, the M06SY-II can replace a CNC lathe, a VMC (for cross-drilling and milling), and a second lathe operation for back-end work. That's three machines and three setups consolidated into one. Parts with very heavy milling requirements might still benefit from a dedicated VMC for the milling portion.

03 What's the Y-axis accuracy on the M06SY-II?

The Y-axis positioning accuracy is consistent with Tsugami's precision standards, typically within ±0.005 mm. Box-way construction on the Y-axis provides rigidity for accurate off-center milling. For bolt circle patterns, the combination of C-axis angular positioning and Y-axis radial positioning delivers excellent feature location accuracy.

04 Can the M06SY-II do simultaneous 3-axis milling?

Yes, the Fanuc control supports simultaneous X, Y, and Z interpolation for live tooling operations, enabling contoured milling paths. Combined with C-axis positioning, you can create complex milled features on turned parts. Most CAM systems support post-processing for Y-axis turret lathes.
