Overview

The Tsugami M06SJ-II adds a built-in motor sub-spindle to the turret lathe platform, letting you machine both ends of a part in a single cycle. If you're running parts that need turning, facing, or threading on the back end, the M06SJ-II eliminates the need to flip parts or run them through a second machine.

The machine handles 260 mm (10.24 in) chuck work and 51 mm (2 in) bar stock. Both the main and back spindles run 200-4,500 RPM with a 7.5/11 kW (10/14.8 HP) main spindle motor. The built-in motor sub-spindle provides smooth, accurate pickup of parts from the main spindle, and the 30 m/min rapid traverse on the sub-spindle axis keeps handoff and back-working fast.

The 12-station turret handles both front and back turning operations, indexing between the main and sub-spindle work zones. Rapid traverse rates hit 24 m/min on X and 27 m/min on Z, plus 30 m/min on the sub-spindle A-axis. At 5,270 kg and 2,470 x 1,850 x 1,750 mm, the M06SJ-II is a substantial machine that can handle the forces of simultaneous and alternating spindle operations without flinching.

The M06SJ-II makes economic sense for shops producing parts that currently require two operations or two machines for front and back turning. Pins, bushings, fittings, and any part with features on both ends are natural fits. You'll get better concentricity between front and back features since the part stays in the machine, and you cut your cycle time by eliminating the flip operation.

Strengths & Limitations

Strengths

Built-in motor sub-spindle enables complete front and back machining in a single cycle
Both spindles run 200-4,500 RPM for consistent performance on front and back operations
30 m/min sub-spindle rapid traverse minimizes part handoff time between spindles
12-station turret provides ample tool positions for complex front and back turning cycles
Eliminates flip operations and second setups, improving concentricity and reducing cycle time
5,270 kg machine weight provides stability for simultaneous main and sub-spindle operations

Limitations

No live tooling means milling, cross-drilling, and tapping still require secondary operations
Sub-spindle adds cost and complexity compared to simpler J-series turret lathes
Larger footprint than J-series machines takes more floor space
12-station turret must serve both spindles, potentially limiting tool count per side

Best For

Production shops making parts that need turning features on both ends in tight tolerance Fastener and fitting manufacturers producing pins, studs, and connectors with double-end features Bushing and sleeve manufacturers needing precise ID/OD work on both ends Automotive component shops producing parts like valve stems, pivot pins, and guide pins High-volume production cells where eliminating the part flip reduces cycle time significantly

Frequently Asked Questions

01 How does the sub-spindle work on the M06SJ-II?

The built-in motor sub-spindle moves into position behind the main spindle, picks up the part while both spindles are synchronized, and then the part is cut off. The sub-spindle retracts with the part, and back-end turning operations proceed using the same 12-station turret. The entire handoff is automatic and takes just seconds.

02 What's the difference between the M06SJ-II and M06SD-II?

Both have sub-spindles. The key difference is that the M06SD-II adds live tooling capability to the 12-station turret, enabling milling and drilling operations in addition to turning. The M06SJ-II is turning-only. Choose the SD variant if your parts need cross-holes, flats, or other milled features along with front/back turning.

03 Can the M06SJ-II do simultaneous cutting on both spindles?

The machine supports alternating operations between the main and sub-spindle using the shared 12-station turret. True simultaneous cutting with separate tools on both spindles isn't possible with a single turret. For simultaneous operations, you'd need a machine with independent tool systems on each spindle.

04 How accurate is the part handoff to the sub-spindle?

Part handoff accuracy on the M06SJ-II is excellent, with typical runout of 0.005 mm or less after pickup. The built-in motor sub-spindle provides smooth synchronization with the main spindle during handoff. This maintains tight concentricity between features machined on the front and back ends of the part.
