Overview
The ANCA TX7 Linear is ANCA's flagship high-production CNC tool grinder, distinguished by its full linear motor drive system across all primary axes. By eliminating ballscrews and replacing them with linear motors, the TX7 achieves faster axis acceleration, zero backlash, and superior surface finish compared to conventional drive systems — making it the preferred choice for manufacturers producing high-precision solid carbide tools at scale.
The TX7's linear motor axes deliver positioning accuracy of better than ±1 micron on key axes, enabling it to meet the tightest tolerances demanded in aerospace, medical, and electronics tooling. The machine's 20 kW direct-drive spindle is one of the most powerful in ANCA's lineup, capable of aggressive stock removal on large-diameter tools while maintaining the surface quality needed for premium cutting tool performance.
Automation is central to the TX7's value proposition. The machine integrates seamlessly with ANCA's robot loader systems and supports wheel pack changing of up to 6 packs, enabling complex multi-operation grinding of different tool types within a single unmanned shift. ANCA's LaserPlus in-process measurement system is available as an integrated option, providing real-time diameter measurement and automatic compensation without halting the cycle.
The TX7 is deployed by the world's leading cutting tool manufacturers — including major brands in Germany, Japan, and the United States — where consistent quality at high throughput is non-negotiable. Its combination of linear drive precision, high spindle power, and deep automation capability places it at the top of the CNC tool grinding market.

Frequently Asked Questions
01
The TX7 Linear uses linear motor drives on all primary axes instead of ballscrews. This eliminates mechanical backlash, delivers faster axis acceleration (up to 1g), and achieves sub-micron positioning accuracy. It also features a higher spindle power of 20 kW. The MX7 uses ballscrew drives and has a 15 kW spindle, making it a capable but less precise and less powerful platform.
02
LaserPlus is ANCA's in-process laser measurement system that measures tool diameter and runout during the grinding cycle without stopping the machine. It automatically compensates for wheel wear in real time. It is available as an integrated option on the TX7 and is particularly valuable in high-volume production where maintaining diameter consistency across a full batch is critical.
03
The TX7 can grind the full range of round cutting tools: solid carbide and HSS end mills, drills, reamers, step tools, thread mills, form tools, and burrs, up to 32 mm in diameter (larger with optional attachments). Its 6-axis simultaneous capability and iGrind software cover virtually any cutting geometry.
04
The TX7 integrates with ANCA's range of robot loaders and gantry automation systems, enabling queue-based unmanned production. Combined with the 6-pack automatic wheel changer and LaserPlus measurement, the TX7 can run multiple tool types and sizes through a full shift without operator intervention.
05
While the TX7 can operate in standard industrial environments, achieving its sub-micron accuracy potential requires a thermally stable grinding cell. ANCA recommends coolant temperature control and air conditioning in the machine enclosure area. Most high-end production facilities that justify the TX7's cost already have controlled environments.
