Overview
The Mazak VARIAXIS i-700T is the current production designation of the VARIAXIS i-700 platform, a full simultaneous 5-axis vertical machining center built for multi-surface work on mid-to-large parts. The T suffix identifies the trunnion-style rotary table configuration, and this model sits at the heart of Mazak's VARIAXIS lineup between the i-500 and the i-800T.
The standout specification is the 1,100 mm (43.3 in) Y-axis stroke. Combined with 630 mm (24.8 in) on X and 600 mm (23.6 in) on Z, the work envelope handles parts up to 850 mm (33.46 in) diameter and 500 mm (19.69 in) tall. That Y-axis reach is genuinely unusual for a trunnion-style 5-axis in this class — most competitors top out around 500-600 mm — enabling long aerospace brackets, manifolds, and structural parts without stepping up to a larger-frame machine.
The rotary/tilt table uses Mazak's roller gear cam drive on both the A-axis (+30 to -120 degrees) and C-axis (360-degree continuous). The standard spindle runs at 18,000 RPM with 22 kW (30 hp) through a CAT No.40 taper, confirmed by Mazak's published specifications. Optional 12,000 RPM high-torque spindle configurations are available for heavier cutting in steel and titanium.
Table load capacity is 600 kg (1,323 lb) on the 700 mm (24.8 in) diameter pallet. The 30-tool ATC is standard, with 40, 80, and 120-tool options. Rapid traverse hits 60 m/min (2,362 ipm) on X/Y. The machine ships with MAZATROL Matrix 2 control supporting both conversational and ISO/G-code programming.
Automation options include a two-pallet changer and integration with Mazak's PALLETECH flexible manufacturing system. At approximately 15,000 kg (33,000 lb), the i-700T provides excellent vibration damping for consistent surface finishes during aggressive cuts. The machine competes with the DMG Mori DMU 65, Okuma MU-6300V, and Makino D500.

Strengths & Limitations
Strengths
- 1,100 mm Y-axis travel is significantly longer than competing 5-axis trunnion machines in this table class, accommodating elongated aerospace structural parts
- Roller gear cam drive on both rotary axes eliminates backlash and reduces maintenance compared to worm gear designs
- 600 kg table load capacity handles heavy fixtures and workpieces without deflection during aggressive cutting
- 18,000 RPM standard spindle covers high-speed aluminum work while the optional 12K high-torque spindle handles steel and titanium
- MX Hybrid Roller Guide System balances vibration damping with 60 m/min rapid traverse rates
- PALLETECH-ready design integrates into multi-machine flexible manufacturing cells for lights-out production
Limitations
- CAT No.40 taper limits heavy-duty roughing capacity compared to No.50 machines like the i-800T for titanium and steel
- Standard 30-tool magazine is tight for complex multi-feature parts; upgrading to 80 or 120 tools adds significant cost
- 15,000 kg machine weight requires solid floor preparation and makes shop floor rearrangement expensive
- Mazak proprietary control means no Siemens or Heidenhain option for shops standardized on those platforms

Frequently Asked Questions
01
New VARIAXIS i-700T pricing typically runs $350,000 to $500,000 depending on spindle configuration, tool magazine size, and automation options. A two-pallet changer or PALLETECH integration pushes the price higher. The NEO version with SmoothAi control commands a premium over Matrix 2 models. Used i-700T machines from 2015-2020 appear on the secondary market in the $150,000-$250,000 range.
02
The i-700T is the current production designation. The T suffix explicitly identifies the trunnion-table configuration. Functionally and dimensionally, the i-700 and i-700T are the same machine. Mazak added the T suffix to distinguish it from older non-trunnion models in the VARIAXIS line.
03
The i-800T steps up to a CAT No.50 taper with significantly more spindle torque for heavy cutting in titanium and steel. It has a larger 800mm table, higher 1,000 kg load capacity, and heavier machine weight. The tradeoff is lower spindle speed (10,000 vs 18,000 RPM) and slower rapids. Choose the i-700T for smaller parts and aluminum-heavy work; the i-800T for heavy-duty steel and titanium.
04
Yes. The VARIAXIS i-700 NEO upgrades to the MAZATROL SmoothAi CNC with AI-based spindle vibration detection, Ai Thermal Shield for thermal compensation, and an updated touchscreen interface. The physical platform, axis travels, and work envelope are essentially the same.
