Overview
The Mazak INTEGREX i-250S NEO is a current-generation horizontal multi-tasking machine with two matched 8-inch turning spindles and a tilting B-axis milling head. The S suffix marks the second spindle, which takes the part from the main spindle in-cycle so both ends are finished on one datum. That removes the manual re-chuck, which on parts of this kind is usually the largest single contributor to concentricity error.
Both spindles run to 5,000 rpm on 8-inch chucks. The main spindle is rated 22 kW (30 HP), 15 kW (20 HP) continuous; the second spindle 18.5 kW (25 HP), 15 kW (20 HP) continuous. The continuous ratings are identical, so back-end operations are not derated in practice — worth knowing when the second operation involves more than facing and a chamfer.
The milling spindle is the strongest element on the machine: 24 kW (32 HP) and 124 N·m peak, 22 kW (30 HP) and 91.3 N·m continuous, to 12,000 rpm through HSK-A63 or HSK-T63 tooling. The HSK-T option allows turning and milling tools to share one magazine. The B axis covers -30° to +210° in 0.0001° increments.
Two beds are offered. The 1000U gives 1,077 mm of Z travel and 1,011 mm (40 in) of maximum machining length; the 1500U gives 1,585 mm and 1,519 mm. Maximum machining diameter is Φ670 mm (Φ26 in) either way, so the bed choice is purely a question of part length. X travel is 695 mm (27 in) and Y is 300 mm (12 in), enough off-centre reach for cross-features and angled bores on shaft and flange work. Rapids are 50,000 mm/min (1,969 IPM) on X and Z and 40,000 mm/min on Y.
The 36-tool magazine takes cutters to Φ90 mm, or Φ130 mm (Φ5 in) with adjacent pockets clear, 400 mm (16 in) long and 12 kg (26 lb). Footprint is 4,175 × 3,115 mm (164 × 123 in) for the 1000U and 4,995 mm long for the 1500U, at 2,715 mm (107 in) tall and 13,450 kg (29,652 lb) or 14,750 kg respectively. It fits shops running medium-volume complete parts where the second setup is the bottleneck.

Strengths & Limitations
Strengths
- Two matched 8-inch spindles - main at 22 kW (30 HP), second at 18.5 kW (25 HP), both 15 kW (20 HP) continuous to 5,000 rpm - so back-end work is not derated where it counts
- The second spindle takes the part in-cycle, so both ends are finished on one datum without a manual re-chuck
- The milling spindle is the strongest element on the machine: 24 kW (32 HP) and 124 N·m peak, 22 kW (30 HP) and 91.3 N·m continuous, to 12,000 rpm
- HSK-T63 alongside HSK-A63 lets turning and milling tools share the 36-station magazine
- Y travel of 300 mm (12 in) with 695 mm (27 in) on X gives real off-centre reach for cross-features and angled bores
- Two bed lengths give 1,011 mm (40 in) or 1,519 mm of machining length at the same Φ670 mm (Φ26 in) maximum diameter
Limitations
- The turning spindles reach 5,000 rpm, modest against a Φ670 mm swing - sustained heavy roughing at full diameter is not what this machine is for
- The 36-pocket magazine caps tools at Φ90 mm, 400 mm (16 in) long and 12 kg (26 lb), so heavy boring bars and large shell mills do not fit
- The second spindle occupies the space a tailstock would, so long between-centres work sits outside the S configuration's remit
- At 13,450 kg for the 1000U or 14,750 kg for the 1500U, with a 4,175 x 3,115 mm or 4,995 x 3,115 mm footprint, installation needs engineered floor and crane capacity
- Coordinating two spindles and a B-axis milling head is a real programming step up, and the machine only earns its cost when parts genuinely need both ends finished in one cycle

Frequently Asked Questions
01
It marks the second spindle. It faces the main spindle and takes the part in-cycle, so both ends are finished on one datum rather than in a separate re-chucked operation. On parts of this kind the manual re-chuck is usually the largest single contributor to concentricity error, so removing it is the machine's core argument.
02
On the headline figure yes, on the number that governs sustained cutting no. The main spindle is rated 22 kW (30 HP) and the second 18.5 kW (25 HP), but both are 15 kW (20 HP) continuous and both run to 5,000 rpm on 8-inch chucks. Since sustained cuts are governed by the continuous rating, back-end operations are not derated in practice.
03
The 1000U gives 1,077 mm of Z travel and 1,011 mm (40 in) of maximum machining length; the 1500U gives 1,585 mm and 1,519 mm. Maximum machining diameter is Φ670 mm (Φ26 in) either way, so the choice is purely about part length plus the clearance the second spindle needs. The shorter bed also saves floor: 4,175 mm against 4,995 mm.
04
The milling spindle is the strongest element on the machine: 24 kW (32 HP) and 124 N·m peak, 22 kW (30 HP) and 91.3 N·m continuous, to 12,000 rpm through HSK-A63 or HSK-T63. With 300 mm (12 in) of Y travel and B covering -30° to +210° in 0.0001° increments, it handles cross-features and angled bores as genuine milling work. Tools cap at Φ90 mm and 12 kg (26 lb).
