Machine Comparison
ANCA CPX vs ANCA FX7
ANCA vs ANCA · CNC Grinding Machines
Summary
The ANCA CPX and the ANCA FX7 are both ANCA grinders, but they do different jobs. The ANCA CPX prepares round tool blanks by pinch/peel grinding ahead of fluting; the ANCA FX7 grinds small round tools. ANCA publishes few comparable figures for this pair: spindle power, control and floor space.
The ANCA CPX lists two spindles, a roughing spindle with 43 kW (58 HP) peak power and a finishing spindle with 9.7 kW (13 HP) peak. The ANCA FX7 lists 19 kW (25.5 HP) peak and 8.2 kW (11 HP) S1. Both run the ANCA AMC5 G2 control. The ANCA FX7 is narrower and lower, at 1,930 mm wide and 1,810 mm high against 2477 mm and 2052 mm, but deeper at 1,800 mm against 1659 mm.
Specifications Comparison

| Floor Space | 2477 mm (97.5”) W x 1659 mm (65.3”) D x 2052 mm (80.8”) H | 1,930 mm (76”) W x 1,800 mm (70”) D x 1,810 mm (71”) H |
Advantages
ANCA CPX
- 43 kW (58 HP) peak roughing spindle against 19 kW (25.5 HP) peak on the ANCA FX7
- Separate finishing spindle, 9.7 kW (13 HP) peak, alongside the roughing spindle
- Shallower machine: 1659 mm deep against 1,800 mm
ANCA FX7
- Narrower at 1,930 mm (76”) against 2477 mm (97.5”)
- Lower at 1,810 mm (71”) against 2052 mm (80.8”)
- Suits mixed batches of small tools and long unattended runs
Verdict
These machines sit at different steps of tool production, so the choice follows the job. A shop that prepares its own blanks, with heavy stock removal on round shanks, needs the ANCA CPX and its 43 kW (58 HP) roughing spindle. A shop that grinds small round tools in mixed batches or long unattended runs needs the ANCA FX7, rated 8.2 kW (11 HP) S1. Both use the ANCA AMC5 G2 control, so a toolmaker running both keeps one control across the two.
