Overview
The Hurco TM8Mi is a slant-bed turning center with C-axis and live tooling that delivers mill-turn capability without the complexity or cost of a full Y-axis machine. It sits between the basic TM8i 2-axis lathe and the TMX8MYi full mill-turn in Hurco's lineup, offering the ability to cross-drill, mill flats, tap radial holes, and perform other secondary operations that would otherwise require a trip to the VMC.
The main spindle delivers 13.4 kW (18 hp) at up to 4,500 RPM with an A2-6 spindle nose and 51 mm (2.0 in) bar capacity. Maximum turning diameter is 356 mm (14 in) with a swing over bed of 533 mm (21 in) and maximum turning length of 455 mm (17.9 in). These specs match the TM8i, but the addition of the C-axis and live tooling turret transforms the machine's versatility.
The 12-station turret accepts live tools running at up to 5,000 RPM, enabling milling, drilling, and tapping operations with the workpiece held in the chuck. The programmable C-axis positions the spindle to 0.001 degree, so features like flats, cross-holes, and bolt patterns are accurately placed. Without the Y-axis, you're limited to on-center and radial operations — no off-center milling or pockets with flat bottoms.
Travels are 200 mm (7.9 in) in X and 455 mm (17.9 in) in Z, with rapid traverse at 24 m/min. Construction follows Hurco's standard approach with Meehanite cast iron, 30-degree slant bed, linear guideways, and Yaskawa servo drives. Machine weight is approximately 3,600 kg (7,937 lb).
The WinMax conversational control handles both turning and milling operations in a single integrated workflow. For shops where most parts need turning plus a few cross-holes, flats, or tapped holes, the TM8Mi eliminates secondary operations at a price point well below full Y-axis mill-turn machines. It competes with the Haas ST-10Y (minus Y), Doosan Lynx 2100LM, and Mazak QT-200 with live tooling.

Strengths & Limitations
Strengths
- Live tooling and C-axis eliminate secondary operations for cross-holes, flats, and radial tapping without the cost of a Y-axis machine
- WinMax conversational control integrates turning and milling programming in one intuitive workflow
- 5,000 RPM live tools provide real milling capability for secondary features, not just light drilling
- 51 mm bar capacity supports automated bar-fed production with live tooling operations
- Lower price point than full Y-axis mill-turn machines saves $30,000-$50,000 while still eliminating many secondary ops
- C-axis positions to 0.001 degree for accurate placement of milled and drilled features
Limitations
- No Y-axis limits milling to on-center and radial operations — cannot mill pockets with flat bottoms or off-center features
- 18 hp spindle is adequate for turning but may limit aggressiveness on heavy cuts in stainless and alloy steels
- 455 mm turning length is shorter than TMX-series machines offering 530+ mm
- 12 tool stations can feel tight when mixing turning tools, live drilling, and live milling tools on complex parts
- Hurco dealer network is smaller than Haas or Mazak for service and support in some regions

Frequently Asked Questions
01
The TM8MYi adds a Y-axis for off-center milling operations like pockets with flat bottoms, hex features, and off-center holes. The TM8Mi is limited to on-center and radial operations (cross-holes, flats, radial tapping). If your parts need off-center milled features, the TM8MYi is required. If most milling is just cross-holes and flats, the TM8Mi saves money.
02
Hurco sells through regional distributors who quote per configuration, and the TM8Mi is positioned as an entry into live tooling rather than a full mill-turn — an 8 in chuck, 2 in bar capacity and a 12-station VDI 30 turret with driven tools, but C axis only and no Y axis, so it lists well below a machine like the TMX8MYi. What moves a quote most is the driven-tool holder package, which on a VDI 30 turret is easy to underestimate, plus bar feeder, parts catcher, chip conveyor, steady rest and the WinMax option set. Tooling, chucks and soft jaws are normally quoted separately from the machine.
03
The TM8Mi can cross-drill, radially tap, mill flats and D-cuts, engrave, and perform on-center drilling and tapping — all while the part stays in the lathe chuck. It cannot mill off-center pockets or features that require Y-axis positioning.
04
The TM8Mi and TMM8 are very similar — both are 8-inch chuck lathes with C-axis and live tooling but no Y-axis. The TM8Mi is the current-generation naming. Check with your Hurco distributor for the specific differences in your region, as naming conventions have evolved across model years.
05
Yes. The 51 mm through-spindle bore accepts standard bar feeders. With WinMax's part counting and automatic stop features, the TM8Mi can run unattended bar-fed production including live tooling operations on each part.
