Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Yamazaki Mazak. Configuration moves it a long way.

Overview

The Mazak INTEGREX i-250H S is the second spindle configuration of the 8 in chuck INTEGREX i-250H: a main and a second turning spindle, each with an 8 in chuck and a 5,000 rpm top speed, worked by a 12,000 rpm B-axis milling spindle. Maximum turning diameter is Ø26 in (660 mm) and maximum turning length 40 in (1,016 mm).

The two turning spindles are close to a matched pair. Both are rated 15 kW (20 HP) continuous. They differ only at 40% ED, where the main spindle gives 22 kW (30 HP) and the second spindle 18.5 kW (25 HP). In practice a part can be roughed and finished on either side at similar cutting data, which keeps the two halves of the cycle balanced when the first and second operations remove comparable amounts of material.

A second spindle changes how the part is held, and the table for this version lists no tailstock. Parts are passed from chuck to chuck and finished on the back face without an operator turning them round. For long, slender work that would normally run on a centre, ask Mazak how the part is to be supported.

The milling side carries the HSK-A63 taper and 38 tools of the INTEGREX i-250H, and is rated 22 kW (30 HP) continuous and 91.3 Nm (67 ft-lb) continuous, on 27 in (686 mm) of X, 12 in (305 mm) of Y and 42 in (1,067 mm) of Z. The second spindle adds mass. This version weighs 29,652 lb (13,450 kg) against 28,990 lb (13,150 kg) for the INTEGREX i-250H. For the series Mazak also names an auto jaw changer that replaces 10 sets of chuck jaws on each of the main and second spindles, marked with an asterisk.

Strengths & Limitations

Strengths

Second spindle with its own 8 in chuck and 5,000 rpm, equal to the main spindle in chuck size and speed
Both turning spindles are rated 15 kW (20 HP) continuous, so first and second operations can run at similar cutting data
One 12,000 rpm HSK-A63 milling spindle with a -30° to +210° B-axis serves both chucks
38-tool magazine with tools up to 16 in (406 mm) long
Mazak names an auto jaw changer for the series that replaces 10 sets of jaws on each of the main and second spindles

Limitations

At 40% ED the second spindle is rated 18.5 kW (25 HP), below the 22 kW (30 HP) of the main spindle
No tailstock is listed in the table for this version, which matters for long, slender shafts
The table lists one milling spindle and no lower turret, so only one chuck is being cut at any moment
Maximum tool diameter is Ø4 in (102 mm) unless adjacent pockets are left empty, and tool weight is capped at 26 lb (12 kg)

Best For

Parts finished on both ends in one cycle by transfer between two 8 in chucks First and second operations of similar weight, given 15 kW (20 HP) continuous on each spindle Automated cells using the flat front of the INTEGREX i-H series Chucked parts within Ø26 in (660 mm) that need milling on the front and back faces

Frequently Asked Questions

01 What does the S add to the INTEGREX i-250H?

A second spindle; Mazak's model list gives the configuration of the INTEGREX i-250H S as Second Spindle. It has an 8 in chuck, runs to 5,000 rpm and is rated 15 kW (20 HP) continuous and 18.5 kW (25 HP) at 40% ED. The machine weighs 29,652 lb (13,450 kg), where the INTEGREX i-250H weighs 28,990 lb (13,150 kg).

02 Are the main and second spindles equally powerful?

On the continuous rating, yes: 15 kW (20 HP) each. At 40% ED the main spindle is rated 22 kW (30 HP) and the second spindle 18.5 kW (25 HP). Chuck size is 8 in and maximum speed 5,000 rpm on both, so the heavier interrupted roughing belongs on the main spindle.

03 Does the INTEGREX i-250H S have a tailstock?

Mazak's table for this version lists no tailstock taper or tailstock thrust. The second spindle takes that end of the machine. If your parts are long relative to their diameter and need support at the free end while turning, raise it with Mazak before ordering.

04 What travels and rapids does it have?

X travel is 27 in (686 mm), Y is 12 in (305 mm) and Z is 42 in (1,067 mm). Rapid traverse is 1,969 ipm (50 m/min) in X and Z and 1,575 ipm (40 m/min) in Y. The B-axis range is -30° to +210° with a 0.0001° indexing increment.

05 How large is the machine?

The footprint is 164 in (4,166 mm) × 106 in (2,692 mm) (W × L), the height is 107 in (2,718 mm) and the weight is 29,652 lb (13,450 kg). Mazak describes the front of INTEGREX i-H machines as flat so that automation such as articulated robots and stockers can be linked to it.
