Advantages
DN Solutions SMX 3100ST
- 12 in chuck as standard, where the e-420H needs an option to go past 10 in (254 mm)
- Lighter, at 18,500 kg (40,786 lb) against approx. 20,000 kg (44,092 lb)
Mazak INTEGREX e-420H
- 4,000 RPM spindle against 3,000 rpm
- Optional long bed with 3,048 mm (120 in) of turning length, at extra cost
Verdict
Since turning capacity and power are level on the published figures, the choice comes down to speed, length and chuck. Choose the Mazak INTEGREX e-420H for parts that benefit from 4,000 RPM, or for long shafts if you pay for the optional 3,048 mm (120 in) bed. Choose the DN Solutions SMX 3100ST for chucked production parts that need a 12 in chuck without an option, with both operations completed in one machine.
