ANCA’s Spindle Speed Increaser offers 50,000 rpm

ANCA has developed a high-performance Spindle Speed Increaser kit designed to elevate the capabilities of its FX, MX, and TX grinding machine platforms. The solution allows users to achieve wheel speeds of up to 50,000 rpm, making it suited to small diameter grinding wheels and specialised applications, such as PCD pocket grinding and internal diameter (ID) grinding.

Designed to operate seamlessly within the machine’s grinding spindle, the Spindle Speed Increaser kit enables users to access ultra-high spindle speeds without any special machine modifications. Importantly, it is fully compatible with ANCA’s automatic wheel pack changer, allowing it to sit alongside conventional grinding wheel packs for convenient, automated tool changes.

Suitable for grinding wheels under 10 mm in diameter, the kit opens new opportunities in high-precision grinding applications. Originally developed for the TX platform, the Spindle Speed Increaser is now also offered for FX and MX machines, providing broader access to its capabilities across ANCA’s customer base.


“The regular ANCA grinding spindle runs up to 10,000 rpm – perfect for most standard tool grinding operations using wheels above 75 mm in diameter,” explains Duncan Thompson, ANCA product manager. “However, customers have been asking for a solution to use smaller wheels. These wheels require significantly higher rpm to achieve the surface speeds necessary for optimal grinding, and the Spindle Speed Increaser provides an elegant solution to this challenge.”

At the heart of the Spindle Speed Increaser is a compact geared mechanism driven by the main spindle. This gearing increases output rpm by a factor of approximately seven, achieving speeds up to 50,000 rpm at the grinding wheel.
