Overview

The Mazak INTEGREX i-500 is the large-capacity member of the i-Series, built for shops needing full 5-axis multi-tasking on workpieces too big for the i-400. With a 10-inch chuck and 700 mm (27.56 in) max machining diameter, plus lengths to 3,075 mm (121.02 in), the i-500 handles substantial shaft-type and chucked components in aerospace, energy, and heavy industry.

Axis travels are generous: 845 mm (33.27 in) X-axis, 430 mm (16.93 in) Y-axis. The B-axis uses a roller gear cam with 0.0001-degree resolution, and the C-axis provides full-circumference disc brake clamping. Main turning spindle options range from 2,000 to 4,000 RPM across multiple bore configurations.

Milling spindle options include 12,000 RPM standard, 12,000 RPM high-output, 20,000 RPM high-speed, and No. 50 taper at 10,000 RPM. This range makes the i-500 unusually flexible for different material mixes. Available in base, -S, and -ST configurations on MAZATROL SmoothAi.

The 430 mm Y-axis travel is 72% more than the i-400’s 250 mm. Competitors include DMG Mori CTX gamma 2000 TC and Okuma Multus U5000. New machines run $400,000-$650,000. Used 2012-2020 units trade $180,000-$400,000. Specs sourced from Mazak published data.

Strengths & Limitations

Strengths

700 mm max diameter and up to 3,075 mm length handle large parts exceeding i-400 capacity
430 mm Y-axis is 72% more than i-400’s 250 mm for complex off-center milling on large workpieces
Four milling spindle options (12K std, 12K HO, 20K HS, 10K No. 50) match spindle to material
Roller gear cam B-axis with 0.0001-degree resolution and full-circumference C-axis disc brake for heavy milling rigidity
Multiple spindle bore options optimize for small-diameter speed or large-diameter torque
845 mm X-axis accommodates workpieces up to 10 feet long
Available in base, -S, and -ST for scalable done-in-one capability

Limitations

$400K-$650K is major capital requiring consistent large-part, high-value work
Machine weight and footprint require serious foundation and floor space planning
Programming complexity on large long parts with 5-axis demands experienced programmers
Lower main spindle speeds (2,000-4,000 RPM) limit high-speed small-diameter turning
Lead times often run 6-12 months for new machines

Best For

Aerospace manufacturers machining large structural components, landing gear, and engine shafts in single-setup 5-axis Energy and power generation shops producing turbine shafts and generator components up to 10 feet Oil and gas equipment manufacturers with large-diameter workpieces needing complex angular milling Defense contractors producing large ordnance and naval components in done-in-one processing Heavy equipment manufacturers machining large hydraulic cylinders and drive shafts exceeding i-400 envelope

Frequently Asked Questions

01 What does an i-500 cost?

Base starts around $400K. Loaded with No. 50 milling spindle, expanded magazine, and long bed $550K-$650K. -S/-ST add $75K-$175K. Used 2012-2020 units $180K-$400K.

02 i-500 vs i-400?

i-500 steps up: 27.56 vs 25.9 inch diameter, 430 vs 250 mm Y-axis, lengths up to 121 vs 60 inches. Adds No. 50 taper milling option. Higher cost and floor space.

03 Which milling spindle?

20K RPM for aluminum, 12K standard for general purpose, 12K high-output for harder materials needing more torque, No. 50 at 10K for maximum rigidity on steel and titanium. Most mixed-material shops choose 12K high-output.

04 Unattended operation?

Yes. SmoothAi tool life management, offset compensation, and SMOOTH Monitor remote status. Robotic loading available for chucked work. Bar feeding limited by spindle bore.

05 i-500 vs e-500H?

i-500 is standard i-Series (10-inch chuck, 27.56 inch swing). e-500H is larger e-Series (15-21 inch chuck, 32.28 inch swing) with integrated boring bar system. e-500H is for significantly larger and heavier workpieces.
