Kitamura Mycenter HX630iG vs Makino a120nx
Kitamura vs Makino · Horizontal Machining Centers
Summary
The Kitamura Mycenter HX630iG and the Makino a120nx are both 50-taper horizontal machining centers, but they sit in different size classes and serve different jobs. The HX630iG travels 1,050 x 800 x 850 mm on a 630 x 630 mm pallet rated for 1,200 kg (2,646 lb); the a120nx travels 1,900 x 1,600 x 1,700 mm on a 1,000 mm x 1,000 mm pallet rated for 3,000 kg, or 5,000 kg as an option.
The Kitamura is the faster machine in this table: 12,000 RPM against 8,000 rpm standard, and rapids of 60 m/min (2,362 ipm) against 54,000 mm/min. The Makino offers a 20,000 rpm spindle as an option and holds 204 tools against 60 standard on the HX630iG, which offers up to 120 as an option.
