Mazak INTEGREX 300IISY
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 300IISY is
The Mazak INTEGREX 300IISY 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 610 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 300IISY suits:
- bar work up to φ65 mm fed through the spindle
- parts finished on the back end without a second setup (second spindle, 3500 rpm max)
- drilled, tapped and milled features on a turned part (rotary tool spindle, 10000 rpm max)
- off-center features, on 230 mm of Y travel
Selling a used Mazak INTEGREX 300IISY
The 2001 INTEGREX series page from Mazak lists the 300SY with the note Second Spindle Spec. and a standard chuck size of 10 in x 2, and next to it the 300Y with a single 10 in chuck. On that page the second spindle is the only listed gap between the two names. Before describing the machine, read the plate, then confirm that both spindles and both chucks are fitted and run.
Mazak's pages for this machine from 2001 and 2002 do not name its control model. The series page says only that programming is done in the Mazatrol conversational format and that it comes in 13 languages. Photograph the control's model plate and its software version screen, note the language it is set to, and back up the part programs and tool data if they are meant to stay with the lathe.
The magazine size is one of the options that separates one unit from another. On Mazak's Japanese 300Y and 300SY page, 20 tools are standard, with 40 and 80 as options, and a tool to tool change of 1.3 seconds. Count the pockets on this machine, start the description by stating 20, 40 or 80, and give the holder count that comes along.
That same Japanese page names a 300SY gantry robot system, and it gives the bar work capacity as 65 mm. If a gantry loader or a bar feeder came with this machine, note the maker, the model number and the stock diameters it is set up for, and make clear whether the sale includes it. If one was fitted once and later taken off, say that as well.
Mazak's 2001 INTEGREX application page shows gear hobbing, gear cutting by slotting, keyway slotting, side cutter slotting and inclined face milling, all in one setup next to plain turning. If this shop ran hobs, slotting tools or the holders for them on its 300-II SY, list them apart from the turning and milling holders, because a buyer looking for that work will ask for them by name.
Mazak's 2004 page calls the 300-III its third generation machine and gives it a new control, the Mazatrol FUSION 640 MT Pro, and it lists a 4000 rpm main spindle for the 300-IIIST. Those figures belong to the later model. Read the numeral on the plate before quoting any brochure, because figures copied from a 300-III or 300-IV sheet will not match a 300-II SY.

What fits a Mazak INTEGREX 300IISY
Each of these follows from a published specification above, which is named beside it.
Workholding
The manufacturer gives this machine's workholding as 10 in x 2 (main and second spindle). Every chuck on it travels with the machine, along with any spare or soft jaws, and each is counted in an offer.
Derived from — Chuck size: 10 in x 2 (main and second spindle)
Bar feeder fit
Bar capacity is 65 mm, so a bar feeder for this machine has to be sized for stock up to that diameter.
Derived from — Bar capacity: φ65 mm
What years the Mazak INTEGREX 300IISY was built
Across the units we have tracked, build years run from 2002 to 2011. Observed across 25 marketplaces, not a manufacturer build record.
Mazak INTEGREX 300IISY 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 8 units of this exact designation on the market, drawn from 5 independent sources, spanning model years 2002 to 2011. 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 300IISY
- Build year. The units we tracked were built from 2002 to 2011, across 5 model years.
- Against the published figures. The manufacturer gives max spindle speed 3500 rpm, spindle motor power AC22 kW, chuck size 10 in x 2 (main and second spindle) and bar capacity φ65 mm.
What to check on a Mazak INTEGREX 300IISY
The same list whichever side of the deal you are on.
- B axis through 225 degrees. Mazak gives the milling head a B axis swing of 225 degrees, indexed in 0.001 degree steps. Drive the head through the full 225 degrees in both directions under program control; any alarm, odd sound or early stop goes on the sheet.
- Two spindles with one rating. On the SY, Mazak rates the second spindle the same as the first: 3500 rpm from an AC 22 kW motor, 30 minute rating. Run each to top speed in turn, then hand a part from one chuck to the other and watch that it seats.
- Rotary tool spindle at 10000 rpm. Mazak's rating for the rotary tool spindle is 10000 rpm, AC 15 kW at 25% ED. Mazak says all three spindles have built-in motors, so listen at each housing while it turns at speed and note which one any noise comes from.
- Machining length on the SY. Maximum machining length on the 300-IISY is 1112 mm, where the single spindle 300-IIY is listed at 1552 mm. Take length figures from the SY row only, and measure the longest work this shop has put on it.
- Rapid traverse, three axes. The 2002 English page gives rapid traverse of 30 m/min in X, 15 in Y and 30 in Z, with the C axis at 300 rpm. Jog each axis at full rapid over its whole travel and listen for ball screw or way noise.
- A crankshaft in one setup. That English page shows a crankshaft finished in one setup without a counterbalanced fixture. If the shop has made shafts like that on this lathe, keep a sample part or its drawing number to show a buyer what it has done.
