Manufacturer specifications, what it is built to do, the years we have seen them listed, what tooling fits, and what to check on one. MTE also buys them outright.
What the Mazak INTEGREX i 400S is
The Mazak INTEGREX i 400S is a multi-tasking turn-mill center — a machine for doing turning and milling in one setup — a milling spindle on a B axis working with a main and usually a second spindle, so a part comes off complete. The manufacturer publishes a max turning diameter of 25.910 in / 658 mm. This one is specified with a Y axis, live tooling, a sub-spindle and bar work: off-center milling without a second setup; driven tools in the turret or milling spindle; the part transfers and is finished on the back end; a bar feeder can run stock through the spindle.
What it is built to do
From the figures the manufacturer publishes, a Mazak INTEGREX i 400S suits:
- bar work up to 4.0 in / 102 mm fed through the spindle
- parts finished on the back end without a second setup (second spindle, 10 in chuck)
- drilled, tapped and milled features on a turned part (B-axis milling spindle with tool changer, 12000 rpm)
- off-center features, on 10.24 in / 260 mm of Y travel
Selling a used Mazak INTEGREX i 400S
Mazak's 2017 listing of the i-400S places it beside the i-400 and the i-400ST, three models one letter apart, and says the S stands for the second turning spindle. Take the full model name from the plate, not from memory or an old invoice, and list only the spindles this unit really has, not those of its neighbors in the series.
Mazak also used the name for a hybrid machine. Its 2019 INTEGREX i-400S AM page describes cladding heads that build features from metal powder melted by fiber laser heat, and it lists a maximum machining length of 39.800 in, far shorter than on the plain model. If the plate reads AM, work from that machine's own page, and list the cladding heads and the laser unit that stay with it.
On Mazak's 2014 page the control type for the i-400S is Matrix 2, and that page shows a 9.84 in (250 mm) Y stroke, not the figure in the spec table above. Take a picture of the control's badge and of its software version screen. Read the Y stroke from the plate, or measure it. The 2014 page also lists a function it calls IPS, for monitoring the milling spindle's status; if that screen is on this unit, photograph what it shows.
Mazak lists 36 tools in the magazine as standard, on HSK A63 holders, with 72 or 110 tools as options, and it names HSK A63, KM63 or CAPTO C6 as the spindle connections on offer. Read the connection on the milling spindle and count the magazine pockets. Give both in the description, together with the number of holders of that type that stay with the machine.
The standard milling spindle is rated 12000 rpm and 30 hp on a 40 ED rating, and Mazak also lists an optional 20000 rpm, 15 HP milling spindle. Read the top speed off the milling spindle's plate or the control's settings, state which spindle this machine has, and give that spindle's run hours if the control shows them.
The series notes on the same page mention hookups for bar feeders and gantry loaders, and NC tailstocks, and this model takes bar work up to 4.0 in. If a bar feeder or loader was bought with this unit, record the feeder's maker and model, the bar range it was last set to, and whether it leaves with the lathe.

What fits a Mazak INTEGREX i 400S
Each of these follows from a published specification above, which is named beside it.
Workholding
A 12-inch chuck. Jaw sets, soft jaws and collet chucks for this size are commodity items, but the chuck itself, and any spare jaws, travel with the machine and are counted in an offer.
Derived from — Chuck size: 12 in
Bar feeder fit
Bar capacity is 102 mm, so a bar feeder for this machine has to be sized for stock up to that diameter.
Derived from — Bar capacity: 4.0 in / 102 mm
What years the Mazak INTEGREX i 400S was built
Across the units we have tracked, build years run from 2011 to 2018. Observed across 25 marketplaces, not a manufacturer build record.
Mazak INTEGREX i 400S machines on the market now
We track listings across 25 used-machinery marketplaces, and every competitor in this market is one of them, so this is a view none of them can produce for themselves. Right now there are 9 units of this exact designation on the market, drawn from 6 independent sources, spanning model years 2011 to 2018. A seller is competing with those units, which is why condition, tooling and control generation decide the number.
We count only listings whose model is spelled as this machine’s own designation. Near spellings that may be a different variant are excluded rather than counted, so this is a floor on what is out there, not a total.
What affects the value of a used Mazak INTEGREX i 400S
- Build year. The units we tracked were built from 2011 to 2018, across 5 model years.
- Against the published figures. The manufacturer gives max spindle speed 3300 rpm, spindle motor power 40.0 hp / 30 kw, chuck size 12 in and bar capacity 4.0 in / 102 mm.
What to check on a Mazak INTEGREX i 400S
The same list whichever side of the deal you are on.
- Bed: 1500U or 2500U. Z travel is 62.40 in on the 1500U bed and 100.91 in on the 2500U. Take the bed from the plate, since it sets the longest part the machine takes, either 59.800 or 98.310 in.
- B axis from minus 30 to 210 degrees. Mazak lists the milling head's travel as minus 30 to 210 degrees, with a 0.0001 degree minimum index. Swing it across that whole range from the control and log any alarm and any point where it pauses.
- Second spindle and the W axis. The second spindle carries a 10 in chuck and runs to 4000 rpm at 35.0 hp on a 30 minute rating, and the same table lists a W axis travel of 61.97 in. Run the second spindle to speed, send the W axis the length of its travel, and pass a part across from the main chuck.
- Main spindle and its 12 in chuck. Mazak's figures for the 12 in main spindle are 3300 rpm, rated 30 kW (40.0 hp) for 30 minutes. Run it at that speed with the chuck mounted, then record the chuck's make and how many jaw sets are included.
- C axis contouring. Mazak lists full C-axis contouring with a 0.0001 degree minimum index. Index C to a few set angles and back to zero from the control, and note any alarm or any drift on the position screen.
- SmoothX and its functions. From 2016 Mazak's page gives the control as SmoothX and pairs it with functions such as Intelligent Maza-Check for 5-axis calibration, Intelligent Thermal Shield and Active Vibration Control. Open the control's option list and record the ones present on this unit.
- An AG suffix on the plate. Mazak's 2022 page lists an INTEGREX i-400S AG with HYBRID AUTO GEAR functions for gear production. If the plate reads AG, list the gear cutting tools and the gear software the shop has used with it.
