Overview
The ANCA RX7 is ANCA's flexible production tool grinder, designed for shops that need high-throughput grinding of round tools across a wide diameter range. Where the MX7 is optimized for high-volume end mill and drill production, the RX7 targets versatility — handling everything from small drills and reamers to step tools, form tools, and custom geometries on a single platform.
The RX7 features 5-axis simultaneous interpolation with ANCA's LinX linear motor technology on all primary axes. The machine accommodates tools up to 200 mm (7.87 in) diameter for OD grinding and provides a generous Z-axis travel of 350 mm (13.8 in), giving it an edge over the FX7 for longer tools. Maximum grinding wheel diameter is 203 mm (8 in), compatible with the full ANCA wheel pack ecosystem.
Spindle power is rated at 22 kW (29.5 HP) peak, placing it between the FX7 and MX7 and making it well-suited for production volumes that exceed FX7 capability without requiring MX7-level investment. The RX7 accepts ANCA's 6-station or 8-station automatic wheel changer and integrates with the Fanuc-based robot loader for unattended production runs.
Software runs on ANCA's ToolRoom platform, giving operators access to the full iGrind suite for complex tool geometry programming and the AutoSet laser measurement system for in-process verification. The machine's flexible tooling system accepts a wide range of collets and centres, making changeover between tool types fast and repeatable.
New RX7 machines are typically priced in the $250,000-$380,000 range depending on wheel changer configuration and automation. Used units from 2018-2023 typically appear between $120,000 and $200,000 on the secondary market.

Strengths & Limitations
Strengths
- 350 mm Z-axis travel accommodates longer tools than the FX7, including extended-reach drills and custom form tools
- 22 kW spindle bridges the gap between FX7 and MX7, providing enough power for production volumes without MX7 capital outlay
- 360-degree continuous C-axis eliminates repositioning for complex helical geometries common in step drills and form tools
- Compatible with ANCA's full wheel pack ecosystem and 8-station changer, supporting complex multi-operation grinding sequences
- ToolRoom software flexibility allows programming of non-standard and custom tool profiles not covered by parametric cycles
- Fanuc robot integration with 840-tool capacity makes unattended overnight production runs practical for mid-volume shops
Limitations
- Higher price than the FX7 may be difficult to justify for shops whose production stays within FX7 capabilities
- 22 kW spindle still falls short of MX7's 38 kW for the most aggressive carbide roughing applications
- Machine footprint of 2,050 x 1,850 mm is larger than the FX7, requiring more floor space allocation
- 6-station wheel changer is standard rather than the 8-station, which most production shops will want as an upgrade
- Less market penetration than the MX7 or FX7 means fewer used examples available and a thinner service network familiarity

Frequently Asked Questions
01
The RX7 sits above the FX7 in ANCA's lineup with more spindle power (22 kW vs. 19 kW), longer Z-axis travel (350 mm vs. 274 mm), a continuous 360-degree C-axis, and a larger standard wheel changer (6-station vs. 2-station). The RX7 is optimized for production flexibility across many tool types, while the FX7 targets a more defined range of smaller tool diameters. Price difference is typically $50,000-$80,000 new.
02
The RX7 excels at step drills, reamers, form tools, and longer-shank tools that exceed the FX7's Z-travel. Its continuous C-axis and higher spindle power also make it efficient for complex helical geometries. For straightforward end mills and standard drills in high volume, the MX7 would typically be the better choice.
03
Yes. The RX7 integrates with ANCA's Fanuc-based robot loader system, which can hold up to 840 tools for unattended production. Combined with the 8-station wheel changer, the machine can run multiple tool types in sequence without operator intervention. ANCA's AutoSet laser system provides in-process measurement to maintain quality through long unattended runs.
04
New RX7 machines are typically priced between $250,000 and $380,000 depending on configuration. The 8-station wheel changer and robot loader are additional costs. Used RX7 units from 2018-2023 appear in the $120,000-$200,000 range on the secondary market, though availability is more limited than the higher-volume FX7 and MX7.
