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.

The EURO 7 standard will immensely change the automotive industry: for the first time, not only emissions from combustion engines will be regulated, but also the abrasion of brakes, among other things. The initial conclusion is that the particulate matter produced by many models must be significantly reduced. As a result, OEMs and suppliers are looking for a new solution for the braking system, with coated brake discs currently proving to be the ideal solution for the task.

So how can the various coating systems be applied reliably and efficiently in the context of high-volume production? EMAG offers the answer to this question: a complete solution ready for series production for the coating of brake discs by laser deposition welding, which has already proven itself in production.

The ELC 450 LMD is a machine solution from EMAG that is characterised by its modularity and flexibility. The basic idea behind the ELC 450 LMD is the use of process modules that can be combined and expanded according to customer requirements. The basic version, the ELC 450 LMD, has one process module. The ELC 450 DUO LMD is equipped with two process modules, while the ELC 450 TRIO LMD, as the name suggests, uses three process modules.

These modular machine concepts make it possible to optimally meet customer requirements in terms of shift structure and productivity. This then determines the choice of machine configuration. The ELC 450 LMD can realize both one-shift and two-shift systems. The combination of laser power and application rate determines the most suitable machine concept for the respective application.
