Overview

The Mazak QT-COMPACT 100MY adds Y-axis milling capability to Mazak's smallest compact turning platform, creating a genuine mill-turn workcell in one of the industry's smallest footprints. The 'MY' designation means both Milling (C-axis with live tooling) and Y-axis off-center capability, enabling complex part features that would otherwise require a second operation on a machining center.

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 RPM suits small-diameter work in aluminum, brass, and free-machining steels where surface speed is critical for finish quality. The 12-station BMT turret runs live tools at 6,000 RPM with 2.2 kW (3 hp), and the Y-axis provides 80 mm (+40/-40 mm) of off-center travel for cross-drilling, milling flats, hexagons, and keyways that don't fall on the part centerline.

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), 80 mm (Y), and 250 mm (Z). Rapids reach 20 m/min on X, 12 m/min on Y, and 24 m/min on Z. At roughly 2,400 kg (5,291 lb), the machine is only marginally heavier than the M variant despite the added Y-axis mechanism.

Running on MAZATROL SmoothEz, the QT-COMPACT 100MY is accessible to operators who prefer conversational programming over raw G-code. The combination of Y-axis, live tooling, and compact size makes this machine particularly popular in medical device manufacturing, where small parts with off-center features are the norm. New machines price between $70,000 and $110,000, with used units trading between $35,000 and $70,000. The QT-COMPACT 100MY competes with the Doosan Lynx 2100LY and Nakamura-Tome SC-100MY.

Strengths & Limitations

Strengths

Y-axis with 80 mm travel enables off-center drilling, milling flats, and machining hexagons on small parts without a second operation
8,000 RPM main spindle is optimized for small-diameter work in aluminum and brass where high surface speed drives finish quality
Industry-leading compact footprint fits into tight shop layouts and enables dense multi-machine production cells
MAZATROL SmoothEz conversational control simplifies Y-axis programming with built-in milling cycles for common features
BMT live tooling provides better rigidity and runout than VDI-style tool holders, improving hole quality on cross-drilled features
Lower acquisition and operating cost compared to Swiss-type alternatives while delivering Y-axis milling capability

Limitations

26 mm bar capacity limits the machine to 1-inch bar stock; shops needing 1.5-inch or larger bar must step up to the 200 series
2.2 kW live tool power is adequate for drilling and tapping but insufficient for aggressive milling operations in harder materials
160 mm maximum machining length restricts the machine to short parts; shaft work requires a larger platform
80 mm Y-axis travel is narrower than some competitors, limiting the size of off-center features that can be machined in a single setup
7.5 kW main spindle will struggle with heavy roughing cuts in stainless steel and titanium at the upper end of the turning diameter range

Best For

Medical device manufacturers producing bone screws, implant components, and surgical tools with off-center milled features Electronics and connector manufacturers machining small parts with cross-holes, flats, and keyways in aluminum and brass Job shops seeking an affordable Y-axis turning center for small parts that currently require two operations across a lathe and mill Precision shops producing hydraulic fittings, valve bodies, and pneumatic components with milled features under 1-inch diameter High-volume production cells where multiple compact machines maximize output per square foot of floor space

Frequently Asked Questions

01 What does a new Mazak QT-COMPACT 100MY cost?

New QT-COMPACT 100MY machines start around $70,000-$85,000 for base configuration. Adding high-pressure coolant, chip conveyor, parts catcher, and bar feeder interface brings the price to $95,000-$110,000. Used units from 2018-2023 trade between $35,000 and $70,000 depending on hours and condition.

02 How much does the Y-axis add over the QT-COMPACT 100M?

The Y-axis option adds approximately $10,000-$15,000 to the base price versus the M-only variant. For shops machining parts with any off-center features, the Y-axis pays for itself quickly by eliminating secondary milling operations. Most dealers recommend the MY configuration for new buyers.

03 Can the QT-COMPACT 100MY replace a Swiss-type lathe?

For short parts (under 3:1 length-to-diameter ratio) with moderate complexity, the QT-COMPACT 100MY can often replace a Swiss machine at lower cost and simpler setup. Swiss lathes remain superior for long, slender parts requiring guide bushing support and for very high-volume production with simultaneous machining capability.

04 What control does the QT-COMPACT 100MY use?

Current-generation machines run MAZATROL SmoothEz, Mazak's entry-level conversational CNC. It supports Y-axis milling cycles, live tool programming, and C-axis contouring through a touchscreen interface. Earlier models may have shipped with Matrix Nexus 2 controls.
