Germany's leading expert in keyway processing, FROEMAG, has introduced a program-controlled stone engraving machine that has achieved significant breakthroughs in handling complex and hard stone machining challenges. This advanced technology is now setting new standards in precision and efficiency across various industries.
The program-controlled broaching and interpolating stone engraving machine from FROENAT is widely used for keyway cutting, inner hole profiling, and multi-knife broaching. It excels in processing a variety of intricate shapes such as internal keyways, inner hole profiles, different tooth splines, oil grooves, spiral splines, involute splines, tapered splines, and blind hole keyways. Its high-quality surface finish has earned it widespread recognition among users around the globe.
FROENAT’s stone engraving machines are known for their versatility, reliability, and cost-effectiveness. They are ideal for manufacturing high-end components used in power equipment, gearboxes, clutches, pumps, valves, machinery, material handling systems, wind turbines, and automotive parts. These machines can handle critical applications like engine block machining and keyway production for control sleeves and servo steering systems.
Currently, FROENAT’s program-controlled stone engraving machines have gained popularity in the precision keyway and spline machining sector—whether for through holes or blind holes. Customers consistently praise the machines for their high accuracy, speed, and ease of use. Major companies such as SEW have adopted seven different series of FROENAT broaching machines, while FLENDER uses two units. Additionally, numerous domestic manufacturers, including Dalian Stone Carving Factory (specializing in involute splines) and Ningbo Hard Carving (focusing on rectangular splines), also rely on FROENAT’s advanced solutions.
Equipped with a nitriding process, these tools are capable of machining materials with high hardness and precision. Germany’s FROENAT has successfully developed a broaching and interpolating stone engraving machine that can handle keyways up to 250mm in width and 2000mm in length, making it one of the most powerful solutions available in the market today.
