How much does the Mazak SYNCREX 20/8 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 20/8 is a Swiss-type lathe that puts 33 tools around bar up to Ø0.75 in (19 mm). Turning length is listed at 8.07 in (205 mm), and the main and sub spindles both turn at up to 10,000 rpm on 3.7 kW (5 HP) (40% ED) motors.
The tool rows show where the 33 come from. Mazak lists 11 OD tools, 4 cross live tools, 2 end working tools and 8 back working tools, plus boring bar holders for 4 tools on the main side and 4 on the sub side. Eleven turning positions leave room to keep roughing and finishing inserts for more than one job mounted, or to double up on the insert that wears first, so a changeover touches fewer holders. Eight back working positions mean the sub spindle is more than a cut-off and facing station. It has its own tools for drilling, boring and turning the second end.
The SYNCREX 20/7 lists 29 tools and the SYNCREX 20/9 lists 36 tools on the same bar diameter, turning length, 10,000 rpm spindle speed and 7,850 lb (3,561 kg) weight, so the three differ in tooling and not in capacity. The SYNCREX 25/8 keeps the 33 tools and moves to Ø1 in (25 mm) bar.
All six listed axes, X, Y, Z, X2, Y2 and Z2, rapid at 1,378 ipm (35 m/min). Floor space is 48.23 in (1,225 mm) × 88.58 in (2,250 mm) with the MAZATROL SmoothSt control, and the height is 66.93 in (1,700 mm). Mazak states that SYNCREX machines run full bar capacity with no special bar end prep, so the Ø0.75 in (19 mm) figure can be planned on as listed.

Strengths & Limitations
Strengths
- 33 tools: 11 OD, 4 cross live, 2 end working and 8 back working, plus boring bar holders listed 4 / 4 for main and sub
- 8 back working tools give the sub spindle its own tooling for second-end operations
- Main and sub spindle are matched at 10,000 rpm and 3.7 kW (5 HP) (40% ED)
- 1,378 ipm (35 m/min) rapid traverse on X, Y, Z, X2, Y2 and Z2
- Same 7,850 lb (3,561 kg) weight and bar capacity as the SYNCREX 20/7, which lists 29 tools
Limitations
- Cross live tools are limited to 4, and the table gives no speed or power for them
- The tool rows list no B-axis tools, only OD, cross live, end working, back working and boring bar positions
- The spindle motors carry only a 40% ED rating of 3.7 kW (5 HP); no continuous figure is listed
- Bar diameter is capped at Ø0.75 in (19 mm) and turning length at 8.07 in (205 mm)

Frequently Asked Questions
01
Mazak's table lists 11 OD tools, 4 cross live tools, 2 end working tools and 8 back working tools. Boring bar holders are listed 4 / 4 for main and sub. Together those rows make up the 33 tools in the tool capacity row.
02
Tool count. The SYNCREX 20/7 lists 29 tools against 33 on this model. Bar diameter (Ø0.75 in (19 mm)), turning length (8.07 in (205 mm)), the 10,000 rpm spindle speed, rapid traverse and the 7,850 lb (3,561 kg) weight are the same for both in Mazak's tables.
03
It has the same drive: 10,000 rpm and 3.7 kW (5 HP) at 40% ED, the figures listed for the main spindle. It is served by 8 back working tools and by the sub side of the boring bar holders, which are listed 4 / 4 for main and sub.
04
Mazak states that SYNCREX machines run full bar capacity with no special bar end prep. For this model the listed capacity is Ø0.75 in (19 mm). The series also has a removable guide bushing adapter, so the guide bushing can be preset outside the machine.
05
Width is 48.23 in (1,225 mm) and depth 88.58 in (2,250 mm), given with the MAZATROL SmoothSt control. Height is 66.93 in (1,700 mm) and weight 7,850 lb (3,561 kg). The footprint row does not mention a bar feeder, which needs its own space in line with the spindle.
