Más de 10 años de experiencia

The use of right tools, an optimized approach, along with experience makes for a shorter time to market. while ensuring high precision with tight tolerance. No matter your CNC milling needs, we are the right choice!

What Is CNC Milling

CNC Milling is a highly valuable industrial practice that has facilitated the manufacturing process and reduced time to market for startups, prototypes, and businesses alike. Due to its high degree of precision and tight tolerance, it refines a block of metal into an intricate and highly complex piece work piece that can be either used as a prototype or even put in for full-scale manufacturing depending upon its application and the type of material used.

Better than /horizontal/vertical that moves in one direction and is only suitable for making holes, a CNC milling machine moves laterally and axially and removes the material to reveal the final product. The cutter moves at different angles where a computer is controlling its movement, ensuring there are no errors and we can have precision with repeatability.

¿Cómo funciona?

 The process of CNC milling starts with a digital file which is designed by a desiger on CAD Software. The file is then converted into readbale format for the machine (G-code) and uploaded in the machine. The machine table may or may not move depending upon the requirements of the part.

The workpiece is placed on the worktable and worked on by the machine which cuts off the excessive material from around it, revealing the desired shape of the object.


CNC milling is a process similar to CNC turning which is used for designing machine parts that may either be porotypes or ready to be put into mass production. Being one of the most popular processes for custom manufacturing, it can handle irregular geometries of intricate parts and even used to produce for mass production of parts once a prototype is approved.

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.

No it is not. CNC milling is a very versatile process that is combined with other processes like casting & 3D printing. Once CNC milling has milled intricate features and details on a part, the part is then sent for mass production and can be put in aforementioned processes for the prototype to be mass produced.

At Prototool, not only do we have 3 axis and 4 axis CNC milling, but we also have 5 axis(HAAS) CNC milling services. All of these services provide excellent results except when you need finer quality results, we suggest 5-axis CNC milling service instead of 3 axis or 4 axis milling services. But if the requirements can be met with 3 axis CNC milling, we try to save the cost of the customer and avoid higher axis CNC milling.

The cost of a CNC machined part is determined by the following four factors. 1) time required for machining, 2) type of material selected, 3) the geometry of the part to be milled, and 4) the startup cost of the project. Besides the stated requirements of the client, we try to make sure we take a course of action that leads to low cost without compromising the quality of the product produced.
