Overview
The Mazak QT-COMPACT 100M is Mazak's smallest footprint turning center with live tooling capability, designed for high-production machining of small precision parts up to 100 mm chuck size. The 'M' designation indicates milling capability via C-axis and a live tool turret, making it far more than a simple 2-axis lathe despite its compact dimensions.
The main spindle delivers 7.5 kW (10 hp) at 8,000 RPM through an A2-4 spindle nose with 26 mm (1.02 in) bar capacity. The high spindle speed is a deliberate design choice for small-diameter work in aluminum, brass, and free-machining steels where surface speed matters more than brute torque. The 12-station turret accepts BMT-style live tools running at 6,000 RPM with 2.2 kW (3 hp), sufficient for cross-drilling, tapping, and light milling operations on small parts.
The work envelope covers 140 mm (5.51 in) maximum turning diameter and 160 mm (6.30 in) maximum machining length with axis travels of 100 mm (X) and 250 mm (Z). Rapids reach 20 m/min on X and 24 m/min on Z. At roughly 2,200 kg (4,850 lb), the QT-COMPACT 100M occupies minimal floor space, allowing shops to fit multiple machines in cell configurations or tight production areas.
Current models ship with MAZATROL SmoothEz, Mazak's conversational CNC that simplifies programming for operators. The compact footprint and live tooling capability make this machine ideal for medical, electronics, and watch component manufacturers producing small parts at volume. New machines price between $60,000 and $95,000 depending on options, with used units from recent years trading between $30,000 and $60,000. The QT-COMPACT 100M competes with the Citizen Cincom L20, Star SR-20J, and Tsugami M08SY in the small-part turning space. Specs sourced from Mazak published data and dealer documentation.

Strengths & Limitations
Strengths
- Ultra-compact footprint allows multiple machines in tight production cells, maximizing output per square foot of shop floor
- 8,000 RPM main spindle delivers excellent surface speed for small-diameter aluminum, brass, and free-machining steel parts
- MAZATROL SmoothEz conversational control reduces setup and programming time, making the machine accessible to operators without advanced G-code skills
- BMT live tooling turret enables cross-drilling, tapping, and milling to reduce secondary operations on small parts
- Low acquisition cost compared to Swiss-type machines while offering live tooling capability for moderately complex parts
- Light machine weight of 2,200 kg simplifies installation and does not require heavy foundation work
Limitations
- 26 mm bar capacity limits the machine to 1-inch bar stock; shops regularly running larger bar need the QT-COMPACT 200 or 300
- 7.5 kW spindle power is modest and will struggle with aggressive roughing in stainless steel or titanium at larger diameters
- No Y-axis on the M variant limits milling capability to features on or near the part centerline; off-center work requires the MY model
- 160 mm maximum machining length restricts the machine to short parts; longer shaft work requires a different platform
- Live tool power at 2.2 kW limits milling operations to light cuts, small drills, and tapping rather than heavy material removal

Frequently Asked Questions
01
New QT-COMPACT 100M machines with standard configuration start around $60,000-$75,000. Adding options like high-pressure coolant, chip conveyor, parts catcher, and bar feeder interface pushes the price to $80,000-$95,000. Used units from 2018-2023 typically trade between $30,000 and $60,000 depending on hours and options.
02
The QT-COMPACT 100M has C-axis and live tooling for milling on the part centerline. The 100MY adds Y-axis travel for off-center milling operations like flats, hexagons, and cross-holes that don't fall on the centerline. The MY variant adds approximately $10,000-$15,000 to the price.
03
Swiss-type lathes (Citizen, Star, Tsugami) use a guide bushing for superior accuracy on long, slender parts and typically have more live tool stations. The QT-COMPACT 100M is simpler to set up, less expensive, and better suited for short parts that don't need guide bushing support. For parts under 3:1 length-to-diameter ratio, the QT-COMPACT is often the more cost-effective choice.
04
The machine accepts standard bar feeders compatible with 26 mm bar capacity. LNS Quick Load Servo 26 and FMB Turbo 3-26 are popular choices. Budget $12,000-$25,000 for a quality bar feeder. The compact machine footprint means shorter bar feeders are typically used to keep the overall cell length manageable.
