Overview

The Mazak VARIAXIS C-700 is the larger sibling of the C-600 in Mazak's automation-focused VARIAXIS C-Series, featuring an integrated twin-pallet changer paired with a 700 mm class work envelope for mid-to-large part 5-axis production. The C designation signals that this machine is purpose-built for continuous automated production rather than flexible job-shop use.

The machine centers on a 603 mm (23.74 in) diameter pallet with axis travels of approximately 700 x 600 x 510 mm (27.56 x 23.62 x 20.08 in). The A-axis swings from +30 to -120 degrees while the C-axis rotates continuously through 360 degrees. Maximum workpiece diameter is 850 mm (33.47 in) by 500 mm (19.69 in) height with a table load capacity of 700 kg (1,543 lb) per pallet. The twin-pallet system enables one pallet to be machined while the operator loads, fixtures, and probes on the second.

The standard spindle runs at 12,000 RPM through a BT40 taper with 22 kW (30 hp). Mazak offers selectable spindle configurations including a 15,000 RPM high-torque option and a 20,000 RPM high-speed variant for aluminum-dominant applications. The MAZATROL SmoothAi CNC provides AI thermal compensation and spindle vibration detection for sustained accuracy across long production runs.

The C-700's larger work envelope compared to the C-600 opens up applications on bigger aerospace brackets, energy sector valve bodies, and structural parts that exceed the C-600's capacity. Standard ATC holds 40 tools with options up to 120. The machine competes with the DMG Mori DMU 65 with pallet changer, Hermle C 400, and Okuma MU-6300V.

Pricing runs $500,000 to $700,000 depending on spindle selection, ATC size, and automation configuration, reflecting the integrated automation premium and larger work envelope.

Strengths & Limitations

Strengths

Integrated twin-pallet changer enables genuine lights-out production with off-cycle part loading, pushing spindle utilization above 80%
850 mm max workpiece diameter and 700 kg load capacity handle larger parts than the C-600 without stepping to a full i-Series machine
Selectable spindle configurations from 12K standard to 20K high-speed adapt the machine to aluminum, steel, or mixed-material production
SmoothAi CNC with AI thermal compensation and vibration detection maintains accuracy across extended production runs
40-tool standard ATC is better equipped for production work than the typical 30-tool base on other VARIAXIS models
PALLETECH-ready for integration into multi-machine flexible manufacturing systems

Limitations

Twin-pallet configuration commands significant price premium over single-pallet 5-axis machines; requires volume to justify
BT40 taper limits maximum torque delivery compared to No.50 machines for heavy roughing in exotic alloys
20,000 kg machine weight requires careful floor loading analysis and may need foundation reinforcement
Programming coordinated pallet-swap operations adds setup complexity compared to single-pallet machines

Best For

Aerospace subcontractors running medium-volume production of structural brackets and housings where spindle utilization directly impacts profitability Medical device manufacturers producing mid-to-large implants and surgical instruments in runs of 50-500 parts Energy sector shops machining valve bodies, pump housings, and turbine components requiring both 5-axis access and production throughput Job shops aiming to differentiate with automated 5-axis capability for larger parts than the C-600 can handle Production environments consolidating multiple machine operations into a single automated 5-axis cell

Frequently Asked Questions

01 What does a Mazak VARIAXIS C-700 cost?

New C-700 pricing runs $500,000 to $700,000 depending on spindle selection, ATC size, and additional automation. The 20,000 RPM high-speed spindle and 120-tool magazine push toward the higher end. The integrated twin-pallet system is included in the base price, which represents a significant value compared to adding a pallet changer to a single-pallet machine.

02 C-600 vs C-700?

The C-700 steps up with a larger work envelope (850 mm vs 600 mm max workpiece diameter), higher table load (700 kg vs 400 kg), and more X/Y travel. Both feature integrated twin-pallet changers. Choose the C-600 for smaller parts where the compact footprint matters; the C-700 for larger aerospace and energy components.

03 Why choose the C-700 over the i-700T with a pallet changer?

The C-700 has the twin-pallet system engineered into the base machine design, not bolted on as an option. This typically provides faster pallet swap times and a more ergonomic loading station. The i-700T with an external pallet changer offers a larger Y-axis stroke (1,100 mm vs 600 mm). Choose the C-700 for production; the i-700T for larger, more complex one-off parts.

04 What spindle should I choose?

12K standard covers mixed steel and aluminum production. 15K high-torque is optimal for shops doing more steel, titanium, and stainless. 20K high-speed is for aluminum-dominant aerospace production where surface speed drives cycle time. Most shops order the 15K configuration.
