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

Best For

Job shops where most parts need turning plus a few cross-holes, flats, or tapped holes Shops eliminating secondary VMC operations on turned parts without investing in full Y-axis mill-turn Medical device manufacturers producing small precision parts with cross-drilled features Hydraulic fitting producers needing radial holes, flats, and threads completed in the lathe Shops stepping up from 2-axis turning to live tooling capability at a moderate price point Small batch manufacturers where WinMax conversational programming saves more time than CAM-driven alternatives

Frequently Asked Questions

01 What is the difference between the TM8Mi and TM8MYi?

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 What does a Hurco TM8Mi cost?

A new Hurco TM8Mi typically sells between $80,000 and $115,000 depending on options. This is approximately $30,000-$50,000 less than a full Y-axis mill-turn machine like the TMX8MYi, making it an attractive entry into mill-turn capability.

03 What operations can the TM8Mi perform with live tooling?

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 How does the TM8Mi compare to the Hurco TMM8?

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 Can the TM8Mi run unattended with a bar feeder?

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.
