Overview

The Mazak QT-Ez 10 is the 10-inch chuck model in Mazak's value-oriented QT-Ez turning center family, stepping up from the QT-Ez 8 with a larger work envelope and more spindle power for mid-size production parts. This is a 2-axis turning-only machine — no milling, no Y-axis — focused on straightforward turning at an accessible price.

The main spindle delivers 18.5 kW (25 hp) at up to 3,500 RPM through an A2-8 spindle nose with 65 mm (2.56 in) bar capacity. The built-in motor spindle eliminates belt vibration and simplifies maintenance. The 12-station turret accepts standard bolt-on tooling. Max turning diameter is 410 mm (16.13 in) over a 580 mm (22.83 in) swing, with 580 mm (22.83 in) of turning length.

Axis travels are 230 mm (X) and 590 mm (Z) with rapids of 30 m/min on both axes. At approximately 4,200 kg (9,259 lb), the QT-Ez 10 is a mid-weight machine that handles well in most shop environments. The A2-8 spindle nose and 10-inch chuck accept standard tooling and handle larger diameter work than the 8-inch model.

Running MAZATROL SmoothEz on a 15-inch touchscreen, the QT-Ez 10 offers conversational programming and G-code capability. It competes with the Haas ST-30, Doosan Puma 3100, and DN Solutions Puma GT 3100. New pricing starts around $75,000-$105,000. For shops needing milling, the QT-Ez 10M variant adds live tooling.

Strengths & Limitations

Strengths

10-inch A2-8 chuck handles mid-size parts that overwhelm 8-inch lathes at a value price point
Built-in motor spindle eliminates belt vibration and reduces maintenance costs
65 mm bar capacity covers standard 2.5-inch production bar stock
18.5 kW (25 hp) spindle provides solid torque for turning steel and stainless at production feed rates
MAZATROL SmoothEz conversational control cuts programming time on turned parts
Competitive pricing puts 10-inch Mazak turning in Haas ST-30 territory

Limitations

3,500 RPM max spindle speed is low compared to 8-inch models, limiting surface speed on smaller diameters
No milling, Y-axis, or sub-spindle — purely a 2-axis turning machine
SmoothEz control lacks some advanced features found on SmoothG
Less established resale market compared to the Quick Turn line

Best For

Production shops turning mid-size parts in the 3-10 inch diameter range that don't need milling Shops adding dedicated 10-inch lathe capacity for high-volume turned parts Automotive and truck component manufacturers producing flanges, hubs, and couplings Contract manufacturers needing affordable 10-inch workhorse lathes for straightforward turning Shops stepping up from 8-inch lathes to handle larger bar stock and chuck work at value pricing

Frequently Asked Questions

01 What does a new Mazak QT-Ez 10 cost?

Base QT-Ez 10 starts around $75,000-$85,000. Adding chip conveyor, tailstock, high-pressure coolant, and bar feeder interface pushes the price toward $105,000. This is one of the most affordable 10-inch Mazak turning centers available.

02 QT-Ez 10 vs QT-Ez 8?

The QT-Ez 10 has a 10-inch chuck (vs 8-inch), A2-8 spindle (vs A2-6), 65 mm bar capacity (vs 52 mm), and 18.5 kW spindle (vs 15 kW). The QT-Ez 8 is faster at 4,500 RPM vs 3,500 RPM. Choose based on maximum part size requirements.

03 QT-Ez 10 vs Haas ST-30?

Both are 10-inch 2-axis lathes in the same price range. The Mazak offers a built-in motor spindle and MAZATROL conversational programming. The Haas typically costs $5,000-$10,000 less with a larger North American service and parts network.

04 Can the QT-Ez 10 handle 2.5-inch bar stock?

Yes. The 65 mm (2.56 in) bar capacity handles standard 2.5-inch bar stock directly. For larger bar diameters up to 3 inches, look at the QTE-300 series with 80 mm bar capacity.
