How much does the Mazak INTEGREX i-300 cost?

Price estimate

Uncertain

We do not have a price for the Mazak INTEGREX i-300 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Mazak INTEGREX i-300 is a 10 in chuck mill-turn machine with an A2-8 spindle nose, 80 mm (3.15 in) of bar capacity and a B-axis milling spindle. Mazak has discontinued it, so what follows is written for someone weighing up a used example, using the listed figures.

Bar capacity is the reason to look at this size. An 80 mm (3.15 in) bore passes stock that a smaller machine would have to take as sawn billets, and the main spindle is listed at 26 kW (35 hp) and 4,000 rpm to cut it. The envelope is listed at 658 mm (25.9 in) in diameter and 1,016 mm (40 in) in length, with travels of 580 mm (22.8 in) in X, 230 mm (9.06 in) in Y and 1,100 mm (43.3 in) in Z.

Milling is by a 12,000 rpm, 18.5 kW (25 hp) spindle on a B axis of 240° (-30° to +210°); a 20,000 rpm spindle is listed as an option. The taper row reads HSK-A63 / Capto C6, so a used machine could carry either interface, and the tooling already in the shop should be matched to it before purchase. The magazine is listed at 36 tools, with 72 or 110 optional. Weight is 12,000 kg (26,455 lb).

Strengths & Limitations

Strengths

80 mm (3.15 in) bar capacity through a 10 in chuck on an A2-8 spindle nose
Main spindle listed at 26 kW (35 hp) and 4,000 rpm
230 mm (9.06 in) of Y travel with a 240° B axis for angled milling and drilling
Listed Z travel of 1,100 mm (43.3 in) for a 1,016 mm (40 in) machining length

Limitations

Discontinued by Mazak; the listed figures should be confirmed against the specific machine
Milling taper is listed as HSK-A63 / Capto C6, so tooling compatibility depends on how the machine was built
Main spindle speed stops at 4,000 rpm, which limits surface speed on small-diameter bar
No second spindle or tailstock figures are listed

Best For

Bar work up to 80 mm (3.15 in) with milled features Shafts and chucked parts up to the listed 1,016 mm (40 in) length Mid-size parts needing 26 kW (35 hp) turning and B-axis milling in one setup

Frequently Asked Questions

01 Is the INTEGREX i-300 still available new?

No. Mazak has discontinued the INTEGREX i-300, so it is found only as a used machine. The figures on this page are the listed ones and are worth checking against the manual and nameplate of any machine on offer.

02 What bar and chuck size does the i-300 take?

The listed chuck is 10 in on an A2-8 spindle nose and the bar capacity is 80 mm (3.15 in). Maximum machining diameter is listed at 658 mm (25.9 in) and maximum machining length at 1,016 mm (40 in). The main spindle is listed at 4,000 rpm and 26 kW (35 hp).

03 Which tool taper does the i-300 milling spindle use?

The table lists HSK-A63 / Capto C6, which means the interface is not fixed by the model name alone. On a used machine, confirm which of the two is fitted before buying holders. The spindle itself is listed at 12,000 rpm and 18.5 kW (25 hp), with 20,000 rpm as an option.

04 What should be checked on a used INTEGREX i-300?

Start with the items the table leaves open: the milling taper (HSK-A63 or Capto C6), the magazine size (36 tools, or the optional 72 or 110) and the milling spindle speed (12,000 rpm, or the optional 20,000 rpm). For moving the machine, the listed weight is 12,000 kg (26,455 lb). Rapids are listed at 50 m/min (1,969 ipm) in X and Z and 40 m/min (1,575 ipm) in Y.
