Machine Comparison
Makino a51nx vs Makino PS95
Makino vs Makino · Makino HMC vs VMC
Summary
The Makino a51nx is a horizontal machining center and the Makino PS95 is a vertical machining center, so the two serve different jobs. Both are 40-taper machines with a 14,000 rpm spindle. The PS95 has the longer X travel, 920 mm against 560 mm, and the higher table load, 800 kg (1,763 lb) against 400 kg (880 lb). The a51nx has more Y and Z travel: 640 mm each against 508 mm and 460 mm.
The a51nx is built for production speed: 60 tools against 30 (expandable to 60), a 0.9 sec tool change against 1.2 sec, 2.2 sec chip-to-chip against 3.8 sec, and 60,000 mm/min (2,362 ipm) rapids against 36 m/min (1,417 ipm).

Advantages
Makino a51nx
- 60 tools standard against 30 (expandable to 60)
- 0.9 sec tool-to-tool and 2.2 sec chip-to-chip against 1.2 sec and 3.8 sec
- 60,000 mm/min (2,362 ipm) rapids against 36 m/min (1,417 ipm)
- 640 mm of Y and Z travel against 508 mm and 460 mm
Makino PS95
- 920 mm (36.2 in) X travel against 560 mm (22.0 in)
- 800 kg (1,763 lb) table load against 400 kg (880 lb)
- Vertical layout suited to mold and die finishing and plate work
Verdict
Choose the Makino a51nx for medium-to-high volume prismatic parts such as housings, manifolds and pump bodies, where horizontal multi-face access, 60 tools and a 2.2 sec chip-to-chip time cut cycle time. Choose the Makino PS95 for mold and die finishing and aluminum work on longer plates that need 920 mm of X travel and 800 kg on the table, especially in a shop moving up from an entry-level VMC.
