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-450H ST carries three places to cut from: a 12 in chuck main spindle, a 10 in chuck second spindle and a lower turret, all under a 12,000 rpm HSK-A63 milling spindle. Mazak's model list gives the configuration as Second Spindle, Lower Turret. It belongs to the INTEGREX i-H series and is listed on the 1500U bed class with 60 in (1,524 mm) of maximum turning length.

The two turning spindles are unequal. The main spindle has 30 kW (40 HP) continuous, 37 kW (50 HP) at 40% ED and a 3,300 rpm limit. The second spindle is smaller and faster: 22 kW (30 HP) continuous, 26 kW (35 HP) at 40% ED and 4,000 rpm. Heavy stock removal therefore belongs at the 12 in chuck, and the part should arrive at the 10 in chuck needing lighter cuts on a diameter that chuck can hold.

Underneath, the lower turret moves 9 in (229 mm) in X2 and 61 in (1,549 mm) in Z2 at 1,575 ipm (40 m/min), and machines diameters up to Ø17 in (432 mm). Its tooling is 1 in (25 mm) in shank height, with Ø1 in (25 mm) boring bar shanks. A tool capacity of 12 tools is listed among the turret rows; the table has no separate count for the milling spindle's magazine, so get that number from Mazak.

The INTEGREX i-H series is the one Mazak builds with a flat front for automation. Among the equipment named for it is an auto jaw changer that replaces 10 sets of chuck jaws on each of the main and second spindles, and the Mazak AUTO FLEX CELL, which places an articulated robot and stockers across the front face. Both carry an asterisk. The machine measures 197 in (5,004 mm) × 106 in (2,692 mm) (W × L) and weighs 37,698 lb (17,100 kg).

Strengths & Limitations

Strengths

Main spindle with a 12 in chuck and 30 kW (40 HP) continuous, 37 kW (50 HP) at 40% ED
Second spindle runs faster than the main, 4,000 rpm against 3,300 rpm, which helps finishing on reduced diameters
Lower turret with 61 in (1,549 mm) of Z2 travel and 9 in (229 mm) of X2 travel
62 in (1,575 mm) of Z travel and 60 in (1,524 mm) of turning length on the 1500U bed class
Flat machine front in the INTEGREX i-H series, which Mazak says improves the link to robots and stockers
Mazak names an auto jaw changer for the series that serves the main and second spindles with 10 sets of jaws each

Limitations

The second spindle's chuck is 10 in against 12 in on the main, and its continuous power is 22 kW (30 HP) against 30 kW (40 HP)
The lower turret is limited to Ø17 in (432 mm), well inside the Ø26 in (660 mm) maximum turning diameter
The 12 tools listed sit with the lower turret rows; no magazine capacity for the milling spindle is stated in this table
Weight is 37,698 lb (17,100 kg) on a 197 in (5,004 mm) wide machine, which needs checking against floor and crane capacity
No tailstock is listed in the table for this configuration

Best For

Heavy first operations at a 12 in chuck followed by lighter second operations at a 10 in chuck Cycles shortened by cutting from the lower turret and the milling spindle together Automated cells with robot loading and automatic jaw changes on both spindles Long turned parts up to 60 in (1,524 mm) within a Ø26 in (660 mm) swing

Frequently Asked Questions

01 Why do the two spindles of the INTEGREX i-450H ST have different chucks?

The table lists a 12 in chuck on the main spindle and a 10 in chuck on the second. The main spindle is the high-power one, 30 kW (40 HP) continuous at up to 3,300 rpm, and the second is rated 22 kW (30 HP) continuous at up to 4,000 rpm. The layout suits parts roughed on the main spindle and finished on the second.

02 What can the lower turret do?

It machines diameters up to Ø17 in (432 mm), with 9 in (229 mm) of X2 travel and 61 in (1,549 mm) of Z2 travel, both at 1,575 ipm (40 m/min) rapid. It holds tools of 1 in (25 mm) shank height and boring bars with Ø1 in (25 mm) shanks. The table lists a tool capacity of 12 tools with these rows.

03 What does ST stand for in this model name?

Mazak's model list gives the configuration of the INTEGREX i-450H ST as Second Spindle, Lower Turret. Both show in the table: second spindle rows for chuck size, speed and power, and lower turret rows for travel, rapid traverse, shank sizes and maximum machining diameter.

04 Which automation options are named for the series?

For the INTEGREX i-H series Mazak names a bar feeder, the Ez LOADER using a collaborative robot, the Mazak AUTO FLEX CELL with an articulated robot and stockers at the front face, and an auto jaw changer that replaces 10 sets of chuck jaws on each of the main and second spindles. All are marked with an asterisk, so confirm what a quotation includes.

05 What are the milling spindle figures?

12,000 rpm, 22 kW (30 HP) continuous and 24 kW (32 HP) at 40% ED, with 91.3 Nm (67 ft-lb) of continuous torque and 124 Nm (91 ft-lb) at 40% ED. The taper is HSK-A63. Tools can be Ø4 in (102 mm), or Ø5 in (127 mm) with adjacent pockets empty, 16 in (406 mm) long and 26 lb (12 kg).
