Hurco vs Makino · Horizontal Machining Centers
Summary
The Hurco HM1700Ri and the Makino a120nx are both large 50-taper horizontal machining centers with 8,000 rpm as the standard spindle speed. The a120nx is bigger on every axis, 1,900 x 1,600 x 1,700 mm against 1,700 x 1,200 x 900 mm, and the gap is widest in Z.
In this table the Makino leads on every row that has a winner. It carries 3,000 kg against 1,360 kg (3,000 lb), or 5,000 kg as an option; it holds 204 tools against 30; it changes tools in 2.2 sec (3.3 sec for 35kg tools) against 3.7 seconds; and it rapids at 54,000 mm/min against 30 m/min (1,181 ipm). It also offers a 20,000 rpm spindle and an HSK-A100 taper as options.

Advantages
Hurco HM1700Ri
- Covers large valve bodies, pump housings and weldments within 1,700 x 1,200 x 900 mm of travel
- Suited to tombstone fixturing for multi-part batches on large components
Makino a120nx
- 1,900 x 1,600 x 1,700 mm of travel against 1,700 x 1,200 x 900 mm
- 3,000 kg standard load (5,000 kg optional) against 1,360 kg (3,000 lb)
- 204 tools against 30
- 2.2 sec tool change and 54,000 mm/min rapids against 3.7 seconds and 30 m/min (1,181 ipm)
Verdict
The Makino a120nx is the stronger choice for high-mix large-part work and heavy roughing: 204 tools, 1,700 mm of Z travel and a 3,000 kg standard load, or 5,000 kg as an option. The Hurco HM1700Ri fits shops whose castings, weldments and tombstone loads stay within 1,700 x 1,200 x 900 mm and 1,360 kg (3,000 lb), and that can work with a 30-tool magazine and 3.7 seconds per tool change.
