How much does the Mazak QT-COMPACT 100MY cost?
Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.
Overview
The Mazak QT-COMPACT 100MY is the 100-size Y-axis configuration in Mazak's QT-COMPACT turning center series, which Mazak describes as a lineup covering turning, milling, Y-axis machining and second spindle options. On Mazak's model list it appears as the QT-COMPACT 100MY L. The listed table shows a 4 in chuck on an A2-4 nose, a 140 mm (5.51 in) maximum turning diameter, 26 mm (1.02 in) of bar capacity and an 8,000 RPM main spindle.
Mazak states that every machine in the series has an integral spindle motor with no gears or belts, and that the main spindle can do C-axis indexing in 0.0001° minimum increments as well as contouring. The turret is a 12 position drum with a milling function, indexed without lifting, with tool holders fixed by four bolts. A 24 position turret is an option. The listed live-tool figures are 6,000 RPM and 2.2 kW (3 hp).
The Y axis is where the sources disagree. The listed table gives 80 mm (±40 mm) of Y travel with a 12 m/min (472 ipm) rapid, while Mazak's series page states a Y-axis stroke of 100 mm (±50 mm). Get the stroke for the exact machine in writing before designing a part around it. The same goes for the control: the table names MAZATROL SmoothEz, and the series page describes the MAZATROL SmoothC CNC system.
For floor planning, Mazak gives 4.39 m² (2600 mm × 1690 mm) for the 500U machines from the 100 series to the 300 series. Series equipment described by Mazak includes an automatic front door, a tool eye, an automatic parts catcher and automatic workpiece measurement with a turret-mounted touch sensor. The page does not say which of these this model includes.

Strengths & Limitations
Strengths
- Listed 8,000 RPM main spindle with 7.5 kW (10 hp), in a series Mazak says has integral spindle motors without gears or belts
- Main-spindle C-axis indexing in 0.0001° minimum increments, plus contouring, per Mazak's series description
- 12 position drum turret with milling function; Mazak offers a 24 position turret as an option
- Mazak gives a floor space of 4.39 m² (2600 mm × 1690 mm) for 500U machines in the series
Limitations
- Y-axis stroke is unclear: the listed table says 80 mm (±40 mm), Mazak's series page says 100 mm (±50 mm)
- Listed bar capacity is 26 mm (1.02 in) and maximum turning diameter 140 mm (5.51 in), so this is a small-part machine
- Live tooling is listed at 2.2 kW (3 hp), which keeps milling light
- Parts catcher, tool eye and workpiece measurement are described for the series with no statement of what this model includes

Frequently Asked Questions
01
The two sources differ. The listed table gives 80 mm (±40 mm) with a Y rapid of 12 m/min (472 ipm). Mazak's series page states a Y-axis stroke of 100 mm (±50 mm) for the QT-COMPACT series. Ask Mazak for the stroke of the specific machine before relying on either figure.
02
The listed table names MAZATROL SmoothEz. Mazak's series page says the QT-COMPACT series is equipped with the MAZATROL SmoothC CNC system, with MAZATROL programming and a home screen for each process. Confirm which control is fitted when quoting.
03
Mazak states that machines with the 500U universal, from the 100 series to the 300 series, install in the same floor space of 4.39 m² (2600 mm × 1690 mm). The listed weight for this model is 2,400 kg (5,291 lb).
04
The QT-COMPACT 100M listing has the same 140 mm (5.51 in) turning diameter, 8,000 RPM spindle and 12-station live turret with no Y-axis row, at a listed 2,200 kg (4,850 lb). The 100MY listing adds the Y travel and Y rapid rows and is listed at 2,400 kg (5,291 lb).
05
An automatic parts catcher that carries finished workpieces to a parts box outside the machine and can be combined with bar feeders or workpiece discharging conveyors. Mazak also states that the QT-COMPACT L series can add safety fences and interlocks for automation with robot systems.
