Machine Comparison
Starrag Heckert H55 vs Starrag Heckert H65
Starrag vs Starrag · Horizontal Machining Centers
Summary
The Starrag Heckert H55 and Starrag Heckert H65 are two sizes of the same horizontal machining center family. They share an HSK-A63 spindle running to 12,000 RPM, 60 m/min (2,362 ipm) rapids, a 60-tool standard magazine, ±0.005 mm positioning and ±0.003 mm repeatability, so the choice is mainly about part size.
The H65 has the larger envelope: 900 x 850 x 1,000 mm of X/Y/Z travel against 750 x 700 x 750 mm, and a 630 x 630 mm pallet against 500 x 500 mm. Its spindle is rated 37 kW (50 hp) against 35 kW (47 HP) continuous. The H55 offers an 18,000 RPM spindle option, magazines of 120 or 240 tools as options, and a choice of Fanuc 31i-B alongside the Siemens SINUMERIK 840D sl.

Advantages
Starrag Heckert H55
- 18,000 RPM spindle option against 12,000 RPM
- Optional 120 or 240-tool magazines
- Choice of Siemens SINUMERIK 840D sl or Fanuc 31i-B control
Starrag Heckert H65
- 900 x 850 x 1,000 mm of X/Y/Z travel against 750 x 700 x 750 mm
- 630 x 630 mm pallet against 500 x 500 mm
- 37 kW (50 hp) spindle against 35 kW (47 HP) continuous
Verdict
Accuracy, speed and rapids are the same, so let pallet size decide. The Starrag Heckert H55 suits automotive and aerospace prismatic parts that fit a 500 x 500 mm pallet, especially in FMS cells, and offers 18,000 RPM and Fanuc as options. The Starrag Heckert H65 is the choice for larger gearbox housings, transmission cases, valve bodies and pump housings that need a 630 x 630 mm pallet and 1,000 mm of Z travel.
