Overview

The Brother Speedio M300Xd1 is the larger mill-turn model in the Speedio line, extending X-travel to 300 mm and turning diameter to 300 mm for larger combined mill-turn work. It builds on the M200Xd1 concept with more capacity while retaining the Speedio high-speed architecture.

X/Y/Z travels are 300 x 440 x 305 mm with a turning spindle handling parts up to 300 mm diameter. The milling spindle runs at 16,000 rpm with 7.5 kW on BT30 taper. The 21-tool turret delivers 0.9-second chip-to-chip changes.

Rapids are 50 m/min on X/Y and 56 m/min on Z. The CNC-C00 control handles mill-turn operations with C-axis indexing and simultaneous interpolation. Machine weight is approximately 3,200 kg.

The M300Xd1 fills a gap between compact mill-turns like the M200Xd1 and full-size multitasking machines from Mazak or DMG Mori. It handles larger parts while costing significantly less.

Ideal for shops producing parts that require both milling and turning but where dedicated multitasking machines are oversized or overpriced for the work.

New machines price $145,000-$190,000. Used trade $65,000-$115,000.

Strengths & Limitations

Strengths

300 mm turning diameter handles larger parts than the M200Xd1
Combined mill-turn eliminates part transfer between machines
Same 0.9s turret tool change for fast milling cycles
Significantly less expensive than full multitasking machines
More X-travel (300mm) than M200Xd1 for wider milling coverage
CNC-C00 handles mill-turn natively

Limitations

300 mm turning diameter still small vs dedicated lathes
BT30 milling spindle limits heavy cutting
Turning capability is more basic than dedicated CNC lathes
Not a replacement for full multitasking machines
21-tool turret may limit complex mill-turn jobs

Best For

Medium-size parts requiring both turning and milling features Medical device components with complex mill-turn geometries Automotive precision parts combining turned and milled features Shops consolidating lathe and mill operations into one machine Prototype and short-run production needing flexible mill-turn Valve and fitting manufacturing combining turning and cross-drilling
