Advantages
Kitamura Mycenter 3XiG
- Sized for parts up to 760 mm (29.9 in) long on a 900 x 410 mm (35.4 x 16.1 in) table, where longer travel would go unused
- CAT 40 / Big Plus (Dual Contact) spindle taper in the published specification
Kitamura Mycenter 4XiG
- 1020 mm (40.2″) of X travel against 760 mm (29.9 in)
- 510 mm (20.1″) of Y and Z travel against 455 mm (17.9 in) and 460 mm (18.1 in)
- 41 HP spindle against 13.4 kW (18 hp)
- 40-tool magazine against a 30-tool side-mount ATC
Verdict
Choose by part length and cutting load. The Kitamura Mycenter 4XiG is the pick for long parts, plates and rows of vises that need 1020 mm (40.2″) of X travel, and for heavier cuts that use its 41 HP spindle and 40 tools. The Kitamura Mycenter 3XiG fits shops whose parts stay within 760 mm (29.9 in) and whose work is drilling, tapping and face milling, where 13.4 kW (18 hp) is enough.
