Understanding CNC Machining

If you're new to CNC machining services, here's a quick primer to get you started:

Icon For CNC Machining

What's CNC Machining


CNC Machining, short for Computer Numerical Control Machining, is a way to make parts using computers to control machine tools. It’s known for:

  • Precision: It makes parts very accurately.
  • Efficiency: It’s fast and can make complex shapes easily.
  • Versatilidad: Used for everything from cars to chairs and boats.

How CNC Machining Works:

  1. Plan the Part: We look at the design and figure out the best way to make it.
  2. Set Up the Machine: We program the machine with the right instructions.
  3. Machining: The machine precisely cuts and shapes the material.
  4. Check Quality: We make sure each part is perfect.

Why Choosing CNC Machining


CNC machining stands out for several key reasons:

Unmatched Accuracy: It’s incredibly precise, making it a top choice for critical industries like aerospace and medical devices. 

Speed and Versatility: Whether it’s a prototype, final product, or a mold, CNC machining works quickly and can handle complex designs with ease. 

Safety and Reliability: The process minimizes human error, ensuring consistent quality and safety. 

Wide Material Compatibility: CNC machining is adaptable, working with a range of materials to meet various industry needs. 

Efficiency for Manufacturers: It requires low maintenance and can operate continuously, making it a cost-effective solution. 

Ideal for Complex Tasks: From milling to turning, CNC machining is perfect for intricate designs and non-conventional machining tasks. 


El mecanizado CNC es un proceso que se utiliza para diseñar piezas de máquinas que pueden ser porotipos o estar listas para la producción en serie. Al ser uno de los procesos más populares para la fabricación a medida, puede manejar geometrías irregulares de piezas intrincadas e incluso se utiliza para producir para la producción en masa de piezas una vez que se aprueba un prototipo.

Admitimos varios formatos de archivo para garantizar que siempre cumplimos los requisitos de nuestros clientes. Esto incluye formatos populares como .stp, .sldprt y .psm/.par. Además, nos aseguramos de trabajar con nuestros clientes hasta el final para que obtengan el resultado deseado diseñado a la perfección. Este es el valor que defendemos.

En Prototool, no sólo tenemos fresado CNC de 3 y 4 ejes, sino que también tenemos servicios de fresado CNC de 5 ejes (HAAS). Todos estos servicios proporcionan excelentes resultados, excepto cuando necesita resultados de calidad más fina, sugerimos el servicio de fresado CNC de 5 ejes en lugar de los servicios de fresado de 3 o 4 ejes. Además, nuestro servicio de torneado CNC emplea una variedad de herramientas y software de última generación que garantizan que sus componentes deseados se creen con exactitud y precisión.

El mecanizado CNC ofrece muchas ventajas. Esto incluye, pero no se limita a, la exactitud, la precisión, la rapidez de entrega, la versatilidad de las soluciones, la capacidad de trabajar con una serie de materiales, y ser una solución económica en general en comparación con otras soluciones presentes en el mercado.

El coste de una pieza mecanizada con CNC viene determinado por los cuatro factores siguientes. 1) el tiempo necesario para el mecanizado, 2) el tipo de material seleccionado, 3) la geometría de la pieza que se va a mecanizar y 4) el coste inicial del proyecto. Además de los requisitos indicados por el cliente, intentamos asegurarnos de que tomamos una línea de actuación que nos lleve a un bajo coste sin comprometer la calidad del producto fabricado. Para determinar el coste de su proyecto, puede solicitar un presupuesto gratuito.
