JTEKT FH630SX vs Makino a120nx
JTEKT vs Makino · Horizontal Machining Centers
Summary
The JTEKT FH630SX and the Makino a120nx are both CAT50 horizontal machining centers, but they sit in different size classes and serve different jobs. The FH630SX travels 1,050 x 900 x 1,050 mm on a 630 mm x 630 mm pallet; the a120nx travels 1,900 x 1,600 x 1,700 mm on a 1,000 mm x 1,000 mm pallet, with 1,250 x 1,000 mm as an option.
The Makino carries 3,000 kg against 1,500 kg (3,306 lb), or 5,000 kg as an option. Spindle speed and tool capacity have no winner in this table: JTEKT lists 8,000 and 15,000 RPM against the Makino's 8,000 rpm with a 20,000 rpm option, and the FH630SX holds 60 tools as standard and up to 330 as an option, against 204 on the Makino.
