Overview

The Hurco TMM8 is a slant-bed CNC turning center with live tooling that bridges the gap between basic 2-axis lathes and full Y-axis mill-turn machines. At 18 hp with an 8-inch 3-jaw chuck, 2-inch bar capacity, and 4,800 RPM spindle, it's sized for the bread-and-butter turned parts that keep most job shops running — shafts, bushings, spacers, and fittings in steel, stainless, and aluminum.

What separates the TMM8 from a standard TM8 is the live tooling turret. The 12-station turret drives live tools at up to 5,000 RPM, enabling cross-drilling, milling flats, tapping radial holes, and other secondary operations without removing the part from the chuck. It doesn't have a Y-axis (the TMX8MYi fills that role in Hurco's lineup), so you're limited to on-center and radial operations, but for many parts that's exactly enough to eliminate a trip to the mill.

The maximum cutting diameter is 10 inches (254 mm) with a swing over bed of 21 inches (533 mm) and a maximum cutting length of 17.9 inches (455 mm). The machine weighs 9,095 lbs (4,125 kg), which gives it decent rigidity for its class. Hurco's hallmark WinMax conversational control is standard, letting operators program parts at the machine without G-code expertise.

The TMM8 competes with the Haas ST-10Y (minus the Y-axis), the Doosan Lynx 2100LM, and the Mazak QT-200 with live tooling. It sits at an attractive price point for shops that want live tooling capability and Hurco's conversational programming without stepping up to the full TMX-series mill-turn machines. If your parts need flats milled, cross-holes drilled, or radial features tapped but don't require off-center milling pockets, the TMM8 saves you $30-50K versus a Y-axis machine.

Strengths & Limitations

Strengths

Live tooling at 5,000 RPM enables cross-drilling, flat milling, and radial tapping without a secondary operation on a mill
WinMax conversational control eliminates the need for CAM software on straightforward turned/milled parts
8-inch chuck with 2-inch bar capacity covers the most common job shop turned part sizes
Lower price point than Y-axis mill-turn machines saves $30-50K while still eliminating many secondary operations
4,800 RPM main spindle is fast enough for aluminum and non-ferrous turning at production feeds
12-station turret provides enough tool positions for most turned parts with a few live tool operations

Limitations

No Y-axis limits milling to on-center and radial operations — can't mill pockets with flat bottoms or off-center features
18 hp spindle is adequate but not powerful — heavy roughing in stainless or Inconel will be slow
17.9-inch max cutting length is shorter than many competitors offering 20+ inches
Hurco's dealer network is smaller than Haas or Mazak, which can affect service response in some regions
4,800 RPM max spindle speed is modest compared to 6,000+ RPM on some competitors

Best For

Job shops adding live tooling capability to eliminate secondary milling operations on turned parts Shops that value conversational programming for fast setup and short-run turned parts Medical device and connector manufacturers running small precision parts with cross-holes and flats Budget-conscious shops stepping up from manual lathes to CNC with live tooling in one move Prototype shops that need to turn and drill/tap parts complete in a single setup

Frequently Asked Questions

01 What is the difference between the TMM8 and TMX8MYi?

The TMM8 has live tooling but no Y-axis. The TMX8MYi adds a 55 mm Y-axis, a more powerful 37.3 hp spindle, and a BMT65 turret. The Y-axis enables milling pockets with flat bottoms and off-center operations. If your parts only need cross-holes, flats, and radial tapping, the TMM8 saves $30-50K. If you need true milling capability, step up to the TMX8MYi.

02 Can the TMM8 run unattended with a bar feeder?

Yes. The 2-inch through-spindle bore accommodates standard bar feeders. With a magazine bar feeder and the WinMax control's part counting and automatic stop features, the TMM8 can run unattended for extended periods on bar stock within the 2-inch diameter limit.

03 How does the Hurco TMM8 compare to the Haas ST-10?

The Haas ST-10 offers similar turning specs at a lower base price, but the Hurco's WinMax conversational control is significantly more intuitive for at-the-machine programming. The ST-10 with live tooling is the closer comparison, and at that point prices are more comparable. Hurco wins on ease of use; Haas wins on dealer network and parts availability.

04 What materials can the TMM8 handle?

The 18 hp spindle handles mild steel, 4140, aluminum, brass, and most stainless grades comfortably at moderate feeds and depths. For aggressive roughing in 304/316 stainless, 17-4 PH, or Inconel, the machine will cut but cycle times will be longer than on a more powerful lathe. It's best suited for parts under 6 inches in diameter in these harder materials.
