How much does the ANCA TG7+ cost?
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 TG7+ is a 6-axis CNC thread grinder: X, Y, Z, A, B and C axes, with the B axis tilting the spindle, for threads from M1 to M80 on workpieces up to 80 mm in diameter and 350 mm long. It does not appear in ANCA's current lineup and may be an older model, so this description rests on the listed figures.
The thread range is listed as M1 – M80 in metric and No. 0 – 3 inch in UNC, UNF and UNEF. The top of both ranges sits at or just under the 80 mm workpiece diameter limit, so the largest threads use the whole envelope. The B axis tilts ±30°. In thread grinding that tilt sets the wheel to the helix angle of the thread, so a thread whose helix angle exceeds 30° is out of reach.
The spindle is listed at 11 kW and up to 10,000 RPM. Accuracy figures are ±0.001 mm for linear axis positioning and ±0.0005 mm for repeatability, with ISO grade 4 thread lead accuracy described as achievable. Read that last word carefully: it is a capability under good conditions, not a promise for every part. Coolant is high-pressure with paper-band filtration, the control is described as ANCA proprietary, Windows-based, with 6-axis simultaneous motion, and the machine weighs approximately 3,500 kg.

Strengths & Limitations
Strengths
- Thread range from M1 to M80, and No. 0 – 3 inch in UNC, UNF and UNEF
- B-axis spindle tilt of ±30° for setting the wheel to the thread helix
- Listed linear positioning accuracy of ±0.001 mm and repeatability of ±0.0005 mm
- High-pressure coolant with paper-band filtration
Limitations
- Workpieces are limited to 80 mm in diameter and 350 mm in length
- B-axis tilt stops at ±30°, which rules out threads with a steeper helix angle
- ISO grade 4 thread lead accuracy is listed as achievable, not as a guaranteed figure
- At approximately 3,500 kg the machine needs a floor and rigging plan to match

Frequently Asked Questions
01
The listed thread range is M1 – M80 in metric and No. 0 – 3 inch in UNC, UNF and UNEF. Maximum workpiece diameter is 80 mm and maximum workpiece length is 350 mm, so the largest threads in the range take up the full diameter capacity.
02
The listed figures describe 6 CNC axes, X, Y, Z, A, B and C, with the B axis providing spindle tilt over a range of ±30°. Tilting the spindle sets the grinding wheel to the helix angle of the thread being ground. A thread with a helix angle beyond 30° cannot be matched by the tilt.
03
Listed linear axis positioning accuracy is ±0.001 mm and repeatability is ±0.0005 mm. Thread lead accuracy is given as ISO grade 4 achievable. On a machine that has seen service, ask for a recent calibration record and a ground test thread instead of relying on the nominal figures.
04
The spindle is listed at 11 kW with speeds up to 10,000 RPM. The coolant system is high-pressure with paper-band filtration. The machine weight is given as approximately 3,500 kg, which matters for the floor and for moving it.
