Principales parámetros técnicos y diseño
1. Sistema de circulación de rodillos: utiliza un retenedor de rodillos de precisión para garantizar una circulación suave y sincrónica de cada rodillo, evitando colisiones y fricciones, manteniendo un bajo nivel de ruido y un bajo aumento de temperatura incluso a altas velocidades.
2. Clase de precisión: ofrece opciones de precisión de primer nivel, desde grado de precisión (P) hasta grado de ultraprecisión (UP), lo que garantiza que las cargas pesadas y la alta precisión no sean mutuamente excluyentes.
3. Configuración de precarga y rigidez: normalmente viene de serie con una precarga pesada (C3) para mejorar la rigidez del sistema; algunos modelos ofrecen una opción de precarga ultra pesada (C5).
4. Tecnología de sellado: Equipado con múltiples sellos y raspadores de alta resistencia para evitar que las partículas grandes y el polvo generado en entornos de carga pesada ingresen a la pista de rodadura.
Aplicaciones
La guía lineal tipo rodillo de la serie RGH-CA/HA es la opción ideal para los siguientes equipos de alta precisión y servicio pesado de primer nivel:
Máquinas herramienta CNC de servicio ultrapesado: ejes lineales centrales de grandes centros de mecanizado de cinco ejes con pórtico, máquinas taladradoras y fresadoras de piso de servicio pesado y rectificadoras de guías.
Equipos pesados de alta precisión: grandes máquinas de medición de coordenadas, máquinas herramienta de procesamiento óptico de ultraprecisión y prensas de alta resistencia para envases de semiconductores.
Energía e industria pesada: equipos de procesamiento de cajas de cambios de energía eólica, grandes líneas de procesamiento de bloques de cilindros de motores diésel y guía de precisión para prensas pesadas.
Equipos de investigación científica de alta gama: mecanismos de carga y movimiento para fuentes de radiación de sincrotrón y plataformas de prueba de componentes de naves espaciales.
La guía lineal tipo rodillo de la serie RGH-CA/HA es una obra maestra que supera los límites físicos de la tecnología de movimiento lineal. Abandona la búsqueda de la aplicabilidad universal a través de una velocidad extrema y baja fricción, llevando en cambio la capacidad de carga, la rigidez y la estabilidad al extremo. No es simplemente un componente, sino una fuerza decisiva para garantizar un mecanizado de alto rendimiento y alta precisión de equipos pesados.

Ball Screw Assembly Workshop
We conduct nut assembly in a constant temperature workshop, all workers
having decades of work experience and zero clearance between the screw
and nut. |

Ball Screw Assembly Workshop
One ball screw shaft matches one ball screw nut. Because each ball screw
shaft has a very tiny different tolerance. There are dozens of different
ball sizes for different screw shaft.
Our ball screw shaft and nut can be interchanged with the Taiwan
TBI ball screw shaft and nut very well. |
