How much does the Mazak SYNCREX 20/9 cost?
Estimated price range
Our best estimate for a swiss-type lathe in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.
Overview
The Mazak SYNCREX 20/9 is a Swiss-type lathe for Ø0.75 in (19 mm) bar whose tool list includes B-axis tools: Mazak's table gives 3 for the main spindle and 3 for the sub, inside a total of 36 tools. Maximum turning length is 8.07 in (205 mm).
A B-axis tool position lets a drill or end mill be set at an angle to the bar instead of square to it. With 3 such tools serving each spindle, angled holes and flats can be cut on the front of a part and again on its back end in one cycle. The table states the count and nothing more. It has no swivel range, speed or power for these tools, so the angles and cutter sizes a part calls for should be confirmed with Mazak before the machine is chosen for that feature.
The other positions are 8 OD tools, 4 cross live tools, 2 end working tools and 8 back working tools, with boring bar holders listed 4 / 4 for main and sub. Both spindles run to 10,000 rpm on 3.7 kW (5 HP) (40% ED) motors, and rapid traverse is 1,378 ipm (35 m/min) on X, Y, Z, X2, Y2 and Z2.
The SYNCREX 20/8 lists 33 tools and the SYNCREX 20/7 lists 29 tools at the same 7,850 lb (3,561 kg) machine weight and the same bar size. The SYNCREX 20/9X shows the same headline figures as this model, 36 tools on Ø0.75 in (19 mm) bar at 10,000 rpm, so those two cannot be told apart on capacity and have to be compared on Mazak's description of each. The footprint of the SYNCREX 20/9 is listed with the MAZATROL SmoothSt control: 48.23 in (1,225 mm) wide, 88.58 in (2,250 mm) deep and 66.93 in (1,700 mm) high.

Strengths & Limitations
Strengths
- B-axis tools listed 3 / 3 for main and sub, for angled features at both ends of the part
- 36 tools in total, including 8 OD tools, 8 back working tools and 4 cross live tools
- Both spindles reach 10,000 rpm with 3.7 kW (5 HP) (40% ED) motors
- Weighs 7,850 lb (3,561 kg), the same as the SYNCREX 20/7 with its 29 tools
- Rapid traverse of 1,378 ipm (35 m/min) on all six listed linear axes
Limitations
- The table gives no swivel range, speed or power for the B-axis tools, only how many there are
- OD turning positions number 8, so long turning sequences have to share space with the other tool groups
- Power is stated at 40% ED only: 3.7 kW (5 HP) per spindle, with no continuous rating
- Capacity ends at Ø0.75 in (19 mm) bar and 8.07 in (205 mm) of turning length

Frequently Asked Questions
01
The table lists B-axis tools as 3 / 3 for main and sub. A B-axis tool can be set at an angle to the bar, so angled holes and flats can be machined without a second operation. Mazak's table does not state the swivel range or the speed of these tools, so check both against the part drawing.
02
36 tools. The rows are 8 OD tools, 4 cross live tools, 2 end working tools, 8 back working tools, boring bar holders listed 4 / 4 for main and sub, and B-axis tools listed 3 / 3 for main and sub.
03
The SYNCREX 20/8 lists 33 tools where this model lists 36, and this model's table includes B-axis tools at 3 / 3 for main and sub. Bar diameter, turning length, the 10,000 rpm spindle speed and the 7,850 lb (3,561 kg) weight are the same for both.
04
No. The SYNCREX 20/9X lists the same Ø0.75 in (19 mm) bar, 8.07 in (205 mm) turning length, 10,000 rpm spindle speed, 36 tools and 7,850 lb (3,561 kg) as the SYNCREX 20/9. The two are the same size, and the difference lies in how Mazak configures each, not in capacity.
05
The main and sub spindle are each rated 3.7 kW (5 HP) at 40% ED, with a top speed of 10,000 rpm on both. No continuous rating appears in the table, so the figure should be read as an intermittent one.
