Our best estimate for a cnc grinding machine in this class — not a quote from ANCA. Configuration moves it a long way.
Overview
The ANCA CPX is a pinch/peel grinder for preparing round tool blanks, listed as a rigid 4-axes design with two wheel spindles: a roughing spindle with 43 kW (58 HP) of peak power and a finishing spindle with 9.7 kW (13 HP). It accepts shanks up to 32 mm (1 1/4”) and tools up to 380 mm long, and its axes are driven by linear motors.
The layout follows the process. The table gives 2 wheel packs, one for roughing and the other for finishing, and each has a spindle sized for its share of the cut. The roughing side has more than four times the peak power of the finishing side, so the bulk of the stock comes off on the big spindle while the finishing wheel is left to set size and surface. Both wheels are on the machine at once, so roughing and finishing do not need a wheel change between them.
For scale, the roughing spindle's 43 kW peak is above the 38 kW (51 HP) peak of the MX7 and the 37 kW (49 HP) peak of the TX7. The CPX table gives peak figures only. It does not state a continuous S1 rating the way the MX7 row does, at 20 kW (27 HP).
Loading is the figure to read carefully. The loader named in the table is the AR300, and the capacity given with it is Ø20 mm (3/4”) x 200 mm (8”) long. The machine itself takes a 32 mm shank and 380 mm of length, so the largest blanks it can grind fall outside what the loader row covers. Find out how those will be handled before planning unattended runs of big blanks.
Floor space is 2477 mm (97.5”) W x 1659 mm (65.3”) D x 2052 mm (80.8”) H. The control is the ANCA AMC5 G2 High Performance CNC with a high speed SSD, EtherCAT, an Intel processor and Windows 10, the same control row the FX5 and MX7 carry.

Strengths & Limitations
Strengths
- Roughing spindle with 43 kW (58 HP) of peak power, above the 38 kW (51 HP) peak listed for the MX7
- A separate 9.7 kW (13 HP) finishing spindle, so the 2 wheel packs for roughing and finishing stay mounted together
- Linear motor drive on a rigid 4-axes structure laid out for pinch/peel grinding
- Accepts shanks up to 32 mm (1 1/4”) and tool lengths up to 380 mm
- ANCA AMC5 G2 High Performance CNC with EtherCAT, a high speed SSD and Windows 10
Limitations
- The AR300 loader capacity is Ø20 mm (3/4”) x 200 mm (8”) long, well short of the 32 mm shank and 380 mm length the machine accepts
- Laid out for pinch/peel grinding, so flutes and cutting geometry are work for a tool grinder such as the MX7
- The table states peak power only for both spindles, with no continuous S1 rating to size long roughing cuts against
- Needs 2477 mm (97.5”) of width and 2052 mm (80.8”) of height, and the table gives no machine weight for planning the floor

Frequently Asked Questions
01
The CPX is a blank preparation grinder. The table describes it as a rigid 4-axes design for pinch/peel grinding, with 2 wheel packs, one for roughing and the other for finishing. It grinds the round blank that a tool grinder later turns into a finished cutting tool. It is not listed as a fluting machine.
02
There are two spindles. The roughing spindle has a peak power of 43 kW (58 HP) and the finishing spindle a peak power of 9.7 kW (13 HP). Both are peak figures. The table does not give a continuous S1 rating for either spindle.
03
The machine takes a tool shank diameter of 32 mm (1 1/4”) and a maximum tool length of 380 mm. With the AR300 loader the listed capacity is Ø20 mm (3/4”) x 200 mm (8”) long. Blanks between those two limits fit the machine but sit outside the loader figure, so ask how they are loaded.
04
The footprint is 2477 mm (97.5”) W x 1659 mm (65.3”) D x 2052 mm (80.8”) H. The table gives no machine weight and does not say whether the footprint includes the AR300 loader, so confirm both before planning the installation and the route into the shop.
05
The axes are driven by linear motors. The control is the ANCA AMC5 G2 High Performance CNC with a high speed SSD, EtherCAT, an Intel processor and Windows 10. The FX5 and MX7 list the same control, which helps a shop that runs blank preparation and tool grinding side by side.
