Machine Comparison
Makino a500iR vs SNK CMV
Makino vs SNK · 5-Axis Machining Centers
Summary
The Makino a500iR and the SNK CMV are five-axis machines from different size classes, and they serve different jobs. The a500iR is a production machining center with 900 x 750 x 800 mm of travel and a 400 kg (880 lb.) load limit. The SNK CMV is a large column-moving machine with configurable travel: X from 2,000 - 4,000 mm, Y from 1,500 - 2,500 mm and Z from 800 - 1,200 mm, with a 10,000 kg (22,046 lb) table load.
The a500iR is the quicker machine: 14,000 rpm standard against 12,000 RPM, 90 tools standard against 60, and 60,000 mm/min (2,362 ipm) rapids against 24 m/min (945 IPM). Both offer faster spindles as options, up to 24,000 rpm on the a500iR and 30,000 RPM on the CMV.
Specifications Comparison
| Specification | Makino a500iR | SNK CMV |
|---|---|---|
| X-Axis Travel | 900 mm (35.4 in) | 2,000 - 4,000 mm (78.7 - 157.5 in), configurable ▲ |
| Y-Axis Travel | 750 mm (29.5 in) | 1,500 - 2,500 mm (59.1 - 98.4 in), configurable ▲ |
| Z-Axis Travel | 800 mm (31.5 in) | 800 - 1,200 mm (31.5 - 47.2 in), configurable ▲ |
| Max Table / Workpiece Load | 400 kg (880 lb.) | 10,000 kg (22,046 lb) ▲ |
| Max Spindle Speed | 14,000 rpm (standard) / 20,000 and 24,000 (optional) ▲ | 12,000 RPM standard (20,000 / 30,000 RPM optional) |
| Spindle Taper / Nose | CAT40 (std/14k) / HSK-A63 (opt/14k; req'd/20k & 24k) | HSK-A63 |
| Tool Capacity | 90 tools (standard) / 133, 218, 311 tools (optional) ▲ | 60 tools standard (120 optional) |
| Rapid Traverse | 60,000 mm/min (2,362 ipm) ▲ | 24 m/min (945 IPM) |
Advantages
Makino a500iR
- 14,000 rpm standard spindle against 12,000 RPM
- 90 tools standard against 60 (120 optional)
- 60,000 mm/min (2,362 ipm) rapid traverse against 24 m/min (945 IPM)
SNK CMV
- X travel configurable from 2,000 - 4,000 mm against 900 mm
- Y travel configurable from 1,500 - 2,500 mm against 750 mm
- 10,000 kg (22,046 lb) table load against 400 kg
- Optional 30,000 RPM spindle
Verdict
These machines are not alternatives for the same part. The SNK CMV is for large aerospace structures, dies and heavy forgings that need at least 2,000 mm of X travel and up to 10,000 kg on the table. The Makino a500iR is for five-axis parts up to 400 kg that fit within 900 mm of X, where its 60,000 mm/min rapids and 90 tools keep production cycles short.
