Our best estimate for a swiss-type lathe in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.

Overview

Small-diameter work is the whole point of the Mazak SYNCREX 12/8: a Swiss-type lathe for bar up to Ø12 mm with a maximum turning length of 135 mm and a main spindle that reaches 15,000 rpm. Mazak groups it with the Ø10 mm to Ø12 mm machines of the SYNCREX series.

Speed matters more than power at this size. On thin bar, 15,000 rpm is what keeps surface speed up as diameters shrink, and the SYNCREX 20/7, a larger-bar sibling, tops out at 10,000 rpm. The sub spindle runs to 12,000 rpm. Both spindles are rated 3.7 kW (5 HP) (40% ED), which is in proportion to the small cross-sections being cut.

The 27 tools are split into 7 OD tools, 4 cross live tools, 6 back-working tools and 2 end-working tools, with boring bar holders at 4 / 4 for main and sub. Six back-working positions on a machine this small let the pickup side do real work: drilling, boring and finishing the cutoff face while the main spindle starts the next part.

Rapid traverse is 35,000 mm/min on X, Y and Z and on X2, Y2 and Z2. The machine is compact at 1,385 mm × 2,242 mm (W × D, with the MAZATROL SmoothSt control), 1,770 mm high and 3,197 kg. The SYNCREX 20/7 weighs 7,850 lb (3,561 kg), so stepping down in bar size saves little mass. The gain is spindle speed.

Mazak states for the series that the guide bushing adapter is removable, so the bushing can be preset outside the machine.

Strengths & Limitations

Strengths

15,000 rpm main spindle, against 10,000 rpm on the SYNCREX 20/7, for cutting speed on bar up to Ø12 mm
12,000 rpm sub spindle with the same 3.7 kW (5 HP) (40% ED) rating as the main
27 tools on a Ø12 mm machine, including 6 back-working tools
Compact installation: 1,385 mm × 2,242 mm footprint and 1,770 mm height
35,000 mm/min rapid traverse on all six listed linear axes

Limitations

Bar capacity ends at Ø12 mm and turning length at 135 mm; the SYNCREX 20/7 takes Ø0.75 in (19 mm) over 8.07 in (205 mm)
3.7 kW (5 HP) at 40% ED per spindle leaves little reserve for heavy cuts in tough alloys
The sub spindle is slower than the main, 12,000 rpm against 15,000 rpm
Only 2 end-working tools are listed, and the table has no B-axis tool row

Best For

Small-diameter turned parts up to Ø12 mm Short, slender components within a 135 mm turning length Work where 15,000 rpm is needed to hold cutting speed on tiny diameters Small parts needing back-end drilling and finishing on the sub spindle

Frequently Asked Questions

01 What is the maximum bar diameter of the SYNCREX 12/8?

Ø12 mm, with a maximum turning length of 135 mm. Mazak places the model in its Ø10 mm to Ø12 mm group. For larger stock, the SYNCREX 20/7 is listed at Ø0.75 in (19 mm) and 8.07 in (205 mm).

02 How fast do the spindles run on the SYNCREX 12/8?

The main spindle reaches 15,000 rpm and the sub spindle 12,000 rpm. Each is rated 3.7 kW (5 HP) at 40% ED. The table gives no continuous rating and no live-tool speed.

03 How many tools does the SYNCREX 12/8 carry?

27 tools: 7 OD tools, 4 cross live tools, 6 back-working tools and 2 end-working tools, with boring bar holders listed as 4 / 4 for main and sub. The SYNCREX 20/8, a larger machine, is listed with 33 tools.

04 How much room does the SYNCREX 12/8 need?

1,385 mm × 2,242 mm (W × D) with the MAZATROL SmoothSt control, and 1,770 mm of height. The machine weighs 3,197 kg. Allow extra length for a bar feeder, which the table does not cover.

05 Why choose the SYNCREX 12/8 over the SYNCREX 20/7?

Spindle speed. The SYNCREX 12/8 runs its main spindle to 15,000 rpm; the SYNCREX 20/7 is listed at 10,000 rpm. If every part is Ø12 mm or smaller and no longer than 135 mm, the faster spindle is the better fit. The SYNCREX 20/7 makes sense when stock up to Ø0.75 in (19 mm) or lengths up to 8.07 in (205 mm) are in the mix, and it carries 29 tools.
