Advantages
Kitamura Mycenter 4XiG
- 1020 mm (40.2″) of X travel and 510 mm (20.1″) in Y and Z, against 300 mm (11.8 in) in each axis
- 800 kg (1,764 lb) table load against 100 kg (220 lb)
- 41 HP spindle against 5.5 kW (7.5 hp)
- 2,362 ipm (60 m/min) rapids against 48 m/min (1,890 ipm), and 40 tools against 16
Kitamura Mycenter-Zero
- 20,000 rpm spindle against 15,000 min⁻¹
- 1.5 seconds tool change against 2.2 sec
- Compact BT30 machine for small parts within a 300 mm (11.8 in) cube
Verdict
Choose by part size. The Kitamura Mycenter 4XiG is for long parts, plates and fixtures up to 800 kg (1,764 lb) that need 1020 mm (40.2″) of X travel and a 41 HP spindle. The Kitamura Mycenter-Zero is for small prismatic parts and drill-and-tap work inside a 300 mm (11.8 in) cube, where 20,000 rpm and a 1.5 seconds tool change shorten the cycle. Accuracy is listed the same on both, so it does not decide the choice.
