Estimated price range
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 GX7 is a 5-axis CNC grinder for gear cutting tools, with X, Y and Z linear axes, A and C rotary axes, and a control described as ANCA CNC with gear tool grinding software. It is not in ANCA's current lineup and may be an older model, so what follows is written from the listed figures for someone assessing an existing machine.
The listed figures give travels of 500 mm (19.7 in) in X, 350 mm (13.8 in) in Y and 250 mm (9.8 in) in Z, and a maximum workpiece of 250 mm (9.8 in) in diameter and 500 mm (19.7 in) in length. A 250 mm diameter is far more than a shank tool needs. It points to disc-shaped gear cutters, which are wide and short, as the intended work. The C axis is the headstock and rotates continuously, while the A axis swivels ±30°, so any setting that needs more swivel than that in either direction is outside the range.
The spindle is listed at 24 kW (32 HP) peak and 8,000 RPM maximum, with a grinding wheel of up to 254 mm (10 in). X and Y run on LinX linear motors and Z on a ballscrew. Positioning accuracy is given as ±0.002 mm (±0.00008 in), and wheel and workpiece probing is integrated and automatic. On an existing machine, check which gear tool software is installed and that the probing works, since both decide what it can grind without extra setup.

Strengths & Limitations
Strengths
- Workpiece capacity of 250 mm (9.8 in) in diameter and 500 mm (19.7 in) in length
- 24 kW (32 HP) peak spindle with a grinding wheel of up to 254 mm (10 in)
- LinX linear motors on X and Y, with a listed positioning accuracy of ±0.002 mm (±0.00008 in)
- Integrated automatic wheel and workpiece probing, and a control with gear tool grinding software
Limitations
- A-axis swivel is limited to ±30° either side
- Z runs on a ballscrew; only X and Y have LinX linear motors
- Spindle speed tops out at 8,000 RPM, and the listed figures give peak power only, with no continuous rating

Frequently Asked Questions
01
Going by the listed figures, it is a 5-axis CNC grinder for gear cutting tools: the control is described as ANCA CNC with gear tool grinding software, and the workpiece capacity is 250 mm (9.8 in) in diameter by 500 mm (19.7 in) in length.
02
The listed travels are 500 mm (19.7 in) in X, 350 mm (13.8 in) in Y and 250 mm (9.8 in) in Z. The C axis, the headstock, rotates continuously and the A axis swivels ±30°. X and Y are driven by LinX linear motors and Z by a ballscrew.
03
The listed figures give 24 kW (32 HP) of peak spindle power and a maximum speed of 8,000 RPM, with a maximum grinding wheel diameter of 254 mm (10 in). No continuous rating is listed, so ask for the spindle data plate or manual when assessing a particular machine.
04
The listed positioning accuracy is ±0.002 mm (±0.00008 in). Integrated automatic wheel and workpiece probing is also listed. On a machine that has been in service, a recent calibration report tells you more than the nominal figure, so ask for one.
