Our best estimate for the Mazak VARIAXIS i-300 is $350,000 - $550,000. This is an estimate for a 5-axis machining centers in this class, not a quote from Yamazaki Mazak; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/mazak-variaxis-i-300#price; the request is passed to Yamazaki Mazak or an authorised dealer.
Mazak's current lineup does not show a machine under the plain VARIAXIS i-300 name, so it may be an older designation. The closest current model is the VARIAXIS i-300 AWC, whose table gives 14 in (356 mm), 22 in (559 mm) and 20 in (508 mm) of X, Y and Z travel and a 143 lb (65 kg) table load.
The listed maximum workpiece is 350 mm (13.78 in) in diameter and 315 mm (12.40 in) high. Table load is listed at 65 kg (143 lb) including the work holder, so a heavy vise or fixture leaves little for the part. Listed travels are 350 mm (13.78 in), 550 mm (21.65 in) and 510 mm (20.08 in).
A built-in motor spindle of 12,000 RPM with a BIG-PLUS BT40 taper, rated 22 kW / 30 hp at 40% ED and 15 kW continuous, with 72 Nm (53 ft-lb) at 40% ED. A high-torque option is listed at 35 kW / 47 hp and 134 Nm (99 ft-lb), and 18K, 25K and 30K RPM spindles are listed as options.
The listed magazine holds 145 tools as standard and is expandable to 505. The listed AWC capacity is 32 workpieces, expandable to 40. The current VARIAXIS i-300 AWC table also gives 145 tools.
