Nippon Seiko Co., Ltd. (en lo sucesivo, NSK) ha desarrollado una nueva generación de husillos de bolas que contribuyen a mejorar la calidad de las superficies mecanizadas para máquinas herramienta de alta precisión, como el mecanizado de moldes.
Este producto puede eliminar o acortar el tiempo de la operación de rectificado para mejorar la calidad de las superficies mecanizadas de la máquina herramienta, reduciendo así el par de fricción dinámico y ahorrando energía. Este producto contribuye a la mejora de la calidad de las superficies mecanizadas.
Este producto se exhibirá en la "JIMTOF2022 31st Japan International Machine Tool Show" que se llevará a cabo del 8 al 13 de noviembre de 2022.
El plan es comenzar a recibir pedidos en abril de 2023, con un despliegue global a partir de entonces. Las ventas esperadas de este producto alcanzarán los 100 millones de yenes para 2024.
