Overview
The Mazak QTE-300M is a 10-inch chuck economy turning center with live tooling and C-axis capability, stepping up from the QTE-200M with a larger work envelope and more spindle power for mid-size production parts. The QTE-300M fills the gap between Mazak's economy 8-inch turning and the full Quick Turn 350 platform.
The main spindle delivers 22 kW (30 hp) at up to 4,000 RPM through an A2-8 spindle nose with 80 mm (3.15 in) bar capacity. The 12-station turret accepts live tools running at 6,000 RPM with 5.5 kW (7.4 hp), providing meaningful milling capability for cross-drilling, tapping, flat milling, and keyway cutting. Max turning diameter is 380 mm (14.96 in) over a 620 mm (24.4 in) swing, with 550 mm (21.65 in) of turning length.
Axis travels are 230 mm (X) and 620 mm (Z) with rapids of 30 m/min on both axes. At approximately 5,200 kg (11,464 lb), the QTE-300M is a substantial machine that requires proper foundation prep. The 10-inch chuck and A2-8 spindle nose handle larger diameter bar stock and bigger chuck work than the 8-inch QTE-200M.
Running MAZATROL SmoothEz on a 15-inch touchscreen, the QTE-300M offers the same conversational programming ease as the rest of the QTE family. It competes with the Haas ST-30Y (minus Y-axis), Doosan Puma 3100M, and DN Solutions Puma GT 3100M. New pricing runs $95,000-$145,000. Specs sourced from Mazak Corporation published data.

Strengths & Limitations
Strengths
- 22 kW (30 hp) spindle with 80 mm bar capacity handles mid-size production parts that overwhelm 8-inch economy lathes
- 5.5 kW live tooling provides real milling power for cross-drilling, tapping, and flat milling on larger parts
- 10-inch A2-8 chuck accepts standard tooling and handles bigger diameter work than the QTE-200M
- MAZATROL SmoothEz conversational programming reduces setup time on short-run turned parts
- Economy pricing puts 10-inch Mazak milling capability 20-30% below the Quick Turn 350M
- 6,000 RPM live tool speed enables reasonable surface speeds on milled features
Limitations
- 4,000 RPM max spindle speed is lower than the QTE-200M's 5,000 RPM, limiting small-diameter surface speed
- No Y-axis on this variant restricts milling to centerline operations; off-center features need the QTE-300MY
- SmoothEz control lacks some advanced SmoothG features found on the Quick Turn platform
- 550 mm turning length limits shaft work; long parts need a Quick Turn long-bed variant

Frequently Asked Questions
01
New QTE-300M machines run $95,000-$145,000 depending on options. The 10-inch model costs roughly $15,000-$25,000 more than the equivalent QTE-200M configuration due to the larger spindle, bigger casting, and heavier construction.
02
The QTE-300M has a 10-inch chuck (vs 8-inch), 22 kW spindle (vs 18.5 kW), 80 mm bar capacity (vs 65 mm), and 5.5 kW live tools (vs 3.7 kW). The QTE-200M is faster at 5,000 RPM vs 4,000 RPM. Choose based on part size requirements.
03
Both are 10-inch turning centers with milling capability. The Mazak offers a built-in motor spindle, MAZATROL conversational programming, and higher live tool power. The Haas costs $10,000-$20,000 less and has a larger North American service network.
04
Yes, the 80 mm (3.15 in) bar capacity handles standard 3-inch bar stock directly. This is one of the key advantages over the QTE-200M, which maxes out at 65 mm (2.56 in). For bar-fed production of larger-diameter parts, the QTE-300M is the right choice.
