Overview

The Mazak INTEGREX j-Series is the value-oriented entry into Mazak’s multi-tasking lineup, designed for shops needing turning plus indexed milling without the full continuous B-axis of the i-Series. The B-axis indexes in 5-degree increments (-30 to +190 degrees), with a 1-degree option available. This makes it significantly less expensive while still eliminating most secondary operations.

The lineup includes three sizes: j-200 (8-inch chuck), j-300 (10-inch), and j-400 (12-inch). All share 500 mm (19.69 in) max machining diameter. The j-200 offers lengths from 500-1,016 mm, j-300/j-400 from 629-1,165 mm. The j-200S adds a second spindle for back-working. Standard 20 tools with 36 and 72 options.

The milling spindle runs to 12,000 RPM with substantial cutting capacity equivalent to a small machining center. The j-Series runs on MAZATROL SmoothAi. This targets shops stepping up from CNC lathes with live tooling, particularly popular in automotive, hydraulics, and general job shops where indexed angles (0, 45, 90 degrees) cover most needs.

New j-Series machines start around $180,000 (j-200) up to $350,000 (loaded j-400). Specs sourced from Mazak published data.

Strengths & Limitations

Strengths

Entry at $180,000 makes multi-tasking accessible to shops that cannot justify $270K+ i-Series
B-axis indexing at 5/1-degree covers 90%+ of typical secondary milling and drilling at standard angles
Same SmoothAi control as i-Series means training transfers directly if shop later upgrades
Three sizes (j-200/300/400) with 8-12 inch chucks cover wide range of parts
12,000 RPM milling spindle provides real machining center performance for indexed operations
j-200S with second spindle enables done-in-one processing at value price
Lower complexity than continuous B-axis reduces programming time and post processor issues

Limitations

5-degree B-axis indexing cannot do continuous interpolation, ruling out true 5-axis contouring
500 mm max diameter is smaller than i-200’s 658 mm
20-tool standard is tight for complex parts
Limited Y-axis travel compared to i-Series for off-center work
Lower resale value due to indexed B-axis limiting future versatility

Best For

Shops stepping up from CNC lathes with live tooling needing proper milling spindle at indexed angles Automotive parts producers making shafts, housings, and fittings with cross-holes at standard angles Hydraulic component shops machining valve bodies with porting at common indexed positions Job shops seeking first multi-tasking machine at accessible price with Mazak quality Production shops where indexed milling eliminates secondary VMC operations

Frequently Asked Questions

01 What does a j-Series cost?

j-200 base starts around $180K. j-200S with second spindle $230K-$280K. j-300/j-400 from $250K-$350K. Used 2015-2020 units trade $80K-$200K.

02 j-Series vs i-Series?

B-axis is the key difference: j indexes in 5/1-degree increments; i provides continuous 0.0001-degree. i-Series does true 5-axis contouring; j handles indexed (3+2) machining. j costs 30-40% less at comparable chuck sizes.

03 Can it do 5-axis machining?

Not simultaneous 5-axis contouring. The j can position B-axis at indexed angles then perform 3-axis milling (3+2). For continuous B-axis interpolation, you need the i-Series or i-NEO.

04 j-Series vs lathe with live tooling?

If secondary ops are simple cross-drilling and flat milling, live tooling is cheaper. Step up to j-Series when you need a proper milling spindle, more tool capacity, or milling at multiple indexed angles. j-Series milling spindle is far more rigid than live tooling.

05 Does it support automation?

Yes. j-200S with second spindle supports bar feeders for lights-out. SmoothAi provides tool life management and remote monitoring. Robotic loading available across lineup.
