Machine Comparison
Hermle C 42 U vs Hermle C 42
Hermle vs Hermle · 5-Axis Machining Centers
Summary
The Hermle C 42 U and the Hermle C 42 appear to be two listings of the same 5-axis machining center, and the table shows it: both have 800 mm of X travel, 800 mm of Y and 550 mm of Z, and both start with a 42-position tool magazine.
The differences lie in how much detail each listing gives. The Hermle C 42 U is listed with a 15,000 rpm standard spindle and up to 42,000 rpm as an extra-cost option. The Hermle C 42 listing spells out the steps: 15,000 / 16,000 / 20,000 / 25,000 rpm on HSK A 63 and 42,000 rpm on HSK E 40. It also gives table load by table type, from 450 kg on the Ø 440 mm table to 2,000 kg on the rigid clamping table.

Advantages
Hermle C 42 U
- One standard build to quote: a 15,000 rpm spindle, with up to 42,000 rpm as an extra-cost option
- Tool magazine listed as expandable from 42 to 160 positions
Hermle C 42
- Spindle choices listed step by step: 15,000 / 16,000 / 20,000 / 25,000 rpm on HSK A 63, or 42,000 rpm on HSK E 40
- Table load published for each table type, up to 2,000 kg on the rigid clamping table
- Additional magazines listed by name, from ZM 30 to ZM 528
Verdict
On travel there is nothing to choose between these two pages: both give 800 x 800 x 550 mm and a 42-position magazine, and both top out at 42,000 rpm. Use the Hermle C 42 page when you need to pick a table and spindle, since it lists loads from 450 kg to 2,000 kg by table type and each spindle from 15,000 rpm upward. Use the Hermle C 42 U page for the standard 15,000 rpm configuration and its magazine expansion to 160 positions.
