Overview

The Mazak INTEGREX e-420H is the big-bore workhorse in Mazak's multi-tasking lineup, built for shops that need to turn, mill, bore, and drill heavy shaft-type workpieces in a single setup. Where the smaller i-200 tops out around 26 inches of swing, the e-420H matches that swing but brings substantially more muscle underneath — a 30/40 hp integral spindle motor, 670 mm (26.4 in) max turning diameter, and bed length options up to 3,000 mm (120 in) for long shaft work.

You're getting a true horizontal multi-tasking center here, not a lathe with live tooling bolted on. The milling spindle runs to 12,000 RPM with 22 kW (29.3 hp) and accepts No. 40, CAPTO C6, or HSK-T63 tooling — proper machining center capability. The B-axis swings 240 degrees (-30 to +210) with roller cam drive and 0.0001-degree indexing resolution, so you can hit complex angular features without refixturing. Pair that with 420 mm (16.54 in) of Y-axis travel — the largest stroke in this class — and 360-degree continuous C-axis, and you've got access to virtually any angle on the workpiece.

Axis travels are generous: 845 mm (33.27 in) on X, 420 mm (16.54 in) on Y, and 1,388 mm (54.65 in) on Z for the standard 1,500 mm bed. Rapids hit 50 m/min (1,969 ipm) on X/Y/Z, keeping repositioning time low when cycling between turning and milling passes. The standard 40-tool ATC handles most jobs, with 80 and 120-tool options for complex aerospace parts needing deep tool libraries.

The e-420H runs on MAZATROL SmoothAi with Ai Thermal Shield on current-generation machines, or Matrix 2 on earlier II-series builds. The machine's high-rigidity construction and C-axis brake mechanism deliver the positioning accuracy you need for simultaneous 5-axis work on large, heavy parts. At roughly 20,000 kg (44,092 lb), this isn't a machine you move around lightly — it needs serious foundation work and rigging.

New e-420H machines price in the $450,000-$650,000 range depending on configuration. Used units from 2010-2016 trade between $150,000 and $350,000 depending on hours, spindle condition, and options. The -S variant adds a second spindle for sub-spindle work, and the -ST adds both a second spindle and lower turret for maximum done-in-one flexibility.

Strengths & Limitations

Strengths

True horizontal multi-tasking with a 12,000 RPM milling spindle delivering 22 kW (29.3 hp) through No. 40, CAPTO C6, or HSK-T63 tooling — this is real machining center capability, not glorified live tooling
420 mm (16.54 in) Y-axis travel is the largest in this class of multi-tasking machines, giving you reach for off-center milling and drilling that smaller Integrex models can't match
240-degree B-axis with roller cam drive and 0.0001-degree indexing resolution provides zero-backlash positioning for simultaneous 5-axis work on complex angular features
Bed length options from 1,500 mm (60 in) to 3,000 mm (120 in) handle everything from mid-size aerospace components to long oil and gas shafts in a single setup
30/40 hp integral spindle motor with C-axis brake delivers the torque and rigidity needed for heavy interrupted cuts on large-diameter workpieces without chatter
40/80/120-tool ATC options mean complex multi-operation parts don't stall for manual tool swaps, and the 1.3-second tool change time keeps cycle times tight
Mazak's massive install base and North American manufacturing in Florence, KY means parts availability and trained service techs are easier to source than with niche European builders

Limitations

New price of $450K-$650K is a serious capital investment that only pays off when you're consolidating three or more operations per part and running high-value work consistently
At 20,000 kg (44,092 lb), the machine requires heavy-duty foundation work and professional rigging — this isn't going on a standard shop floor without reinforcement
4,000 RPM main spindle is adequate for large-diameter work but trails the 5,000-6,000 RPM available on smaller Integrex models and some competitors for high-speed small-diameter turning
Programming complexity is significantly higher than standalone machines; expect 3-6 months for experienced CNC programmers to get productive, and quality post processors for these machines are notoriously hard to find
Sub-spindle part transfer (on -S and -ST variants) requires careful setup and custom macro work — forum users report reliability issues without thorough testing and load detection tuning

Best For

Aerospace shops machining large shaft-type components like landing gear, turbine shafts, and structural members that need turning, milling, and drilling in a single setup to eliminate refixturing errors Oil and gas manufacturers running long workpieces with complex OD/ID features, cross-holes, keyways, and flats that would otherwise require four or more separate setups across multiple machines Heavy equipment and power generation shops producing large-diameter parts where the 670 mm swing and 3,000 mm bed length handle workpieces that smaller multi-tasking machines simply can't fit Job shops running high-value, high-mix parts where setup time and refixturing errors dominate total production cost and consolidating operations delivers immediate ROI Defense contractors producing precision components for naval, missile, and armored vehicle programs where done-in-one processing reduces supply chain complexity and inspection burden Energy sector manufacturers machining pump shafts, valve bodies, and turbine components where the combination of heavy turning and 5-axis milling capability eliminates work-in-process inventory between machines

Frequently Asked Questions

01 What does a new Mazak INTEGREX e-420H cost?

New e-420H machines start around $450,000 for a base configuration. Production-ready setups with 80-tool magazine, high-pressure coolant, and probing typically run $550,000-$650,000. The -S (second spindle) and -ST (second spindle plus lower turret) variants add $50,000-$150,000 on top. Used e-420H machines from 2010-2016 trade between $150,000 and $350,000 depending on hours, spindle condition, bed length, and installed options.

02 How does the e-420H compare to the smaller Integrex i-200?

The e-420H is built for bigger, heavier work. It has a similar 26-inch swing but significantly more spindle power (40 hp vs 30 hp), larger Y-axis travel (16.54 in vs 8.27 in), and bed lengths up to 120 inches vs 40 inches on the i-200. The e-420H weighs roughly twice as much at 44,000 lb. If your parts fit in the i-200's envelope, it's the better value. Step up to the e-420H when you need the Y-axis reach, bed length, or spindle torque for large shaft work.

03 What CAM software works best for programming the INTEGREX e-420H?

MAZATROL conversational programming handles basic turning and milling well. For complex simultaneous 5-axis work, most shops use Esprit, NX, or Mastercam with a quality post processor. Forum users consistently warn that post processors for Integrex machines are tough to source and often need significant customization. Budget time for post development and prove-out. Some experienced operators bypass CAM entirely for turning operations and program at the control, using CAM only for complex milling and 5-axis paths.

04 What are the differences between the e-420H, e-420H-S, and e-420H-ST?

The base e-420H has a single main spindle with a tailstock. The -S variant replaces the tailstock with a second turning spindle (sub-spindle) for back-work and part transfer, enabling complete done-in-one processing of both ends. The -ST variant adds both a second spindle and a lower turret, which works independently for simultaneous cutting operations. The -ST is the most capable but also the most expensive and complex to program.

05 What maintenance does the e-420H require?

Standard maintenance includes spindle oil changes, way lube system checks, hydraulic filter replacement, and coolant system upkeep. The B-axis roller cam drive is long-life but should be inspected annually. Thermal compensation calibration by Mazak service is recommended every 12-18 months for shops holding tight tolerances. The integral spindle motor bearings should be monitored for vibration. Budget $8,000-$15,000 per year for service and consumables on a machine this size.

06 Can the e-420H run unattended?

Yes, with appropriate setup. The machine pairs with bar feeders for stock up to 77 mm (3.03 in) diameter, and chuck-type workholding automation for larger parts. Add a part catcher, chip conveyor, and tool life management through the SmoothAi control for extended unmanned operation. The optional automatic steady rest supports long, slender parts during lights-out cycles. For the -S and -ST variants, sub-spindle part transfer enables complete unattended processing of both ends.
