Overview

The ANCA MX7 is a high-production CNC tool and cutter grinder designed for manufacturing solid carbide and HSS round tools up to 32 mm in diameter. Built on ANCA's proven MX platform, the MX7 combines a robust cast iron construction with the company's proprietary iGrind and ToolRoom software suite, enabling operators to grind complex cutting geometries — drills, end mills, step tools, and form tools — from a single setup.

The machine features ANCA's patented linear motor technology as an upgrade option on key axes, eliminating mechanical drive components and delivering superior surface finish and contour accuracy. The standard ballscrew-driven axes still achieve micron-level positioning repeatability, making the MX7 suitable for both high-volume production environments and precision tool rooms.

At the heart of the MX7 is a direct-drive spindle rated at 15 kW, capable of speeds up to 10,000 RPM, accommodating grinding wheels up to 127 mm in diameter. The integrated wheel pack changer (up to 6 packs) allows automated wheel changes between operations without operator intervention, dramatically reducing cycle times for complex multi-operation tools.

ANCA's proprietary CNC system — running on a Windows-based platform — provides full 5-axis simultaneous control, on-machine measurement via a Renishaw OMP probe, and automatic compensation for wheel wear. The MX7 is a workhorse in aerospace, automotive, and medical device tooling supply chains worldwide.

Frequently Asked Questions

01 What types of tools can the ANCA MX7 grind?

The MX7 can grind a wide range of round tools including solid carbide and HSS end mills, drills, reamers, step tools, burrs, form tools, and thread mills. Its 6-axis simultaneous control and comprehensive iGrind software library cover virtually any round tool geometry up to 32 mm diameter.

02 Does the MX7 support automation for unattended production?

Yes. ANCA offers a range of robot loaders and gantry automation systems compatible with the MX7, enabling queue-based lights-out production. The integrated wheel pack changer (up to 6 packs) also allows the machine to complete multi-wheel operations without operator intervention.

03 What is the difference between the ANCA MX7 and the FX7?

The MX7 is ANCA's higher-production platform, featuring a larger wheelhead, higher spindle power (15 kW vs 11 kW on the FX7), and a broader automation ecosystem. The FX7 is a more compact, cost-effective option suited to tool rooms and lower-volume production runs.

04 Does the MX7 include on-machine measurement?

Yes. The MX7 can be equipped with a Renishaw OMP touch probe for on-machine measurement of tool geometry and automatic compensation for grinding wheel wear, reducing scrapped tools and the need for separate measurement equipment.

05 What CNC control does the ANCA MX7 use?

The MX7 uses ANCA's proprietary CNC system built on a Windows platform, running iGrind and ToolRoom software. It provides full 5-axis simultaneous interpolation and integrates directly with ANCA's suite of measurement and automation software.
