What We Can Do

CNC milling is used for fast delivery of highly precise components that can be either prototypes or for end-users. Moreover, it is used for high volume manufacturing in a variety of processes which include:


No matter the type of prototype, we manufacture prototypes for all fields of technology in a variety of materials.

Medical Parts

Medical Grade materials are milled by CNC machines that are used in a variety of medical purposes. No matter how complicated or delicate the part, with CNC milling, you can have it developed with precision in no time.

Mold Components

With CNC milling, you can have a variety of components developed that are for molding components. this includes sliders, mold cavities and bases, lifters, and other types of components that can be used for mold making.

Plastic & Metal Valves

Valves are difficult components that have intricate geometry, which is why they are difficult to be milled very accurately. With our highly proficient team of engineers, we can make valves with out of any material with out 3-5 axis CNC milling service.

Material We Used

Among a variety of materials that we offer our customers and work with, we also offer our customer the option to source material for them from the market that will fit their desired application.
A highly preferred way to develop prototypes is to have your product milled in plastic. Not only it will allow you to review your product from all angles, but also allow you to test its design and functionality.

Milling Metals is where CNC milling shines the brightest. There are a variety of metals that can be milled to develop prototypes as well as develop end-user parts to put into manufacturing.

Other Materials
Aside from plastics and metals, CNC milling is used to Mill a variety of allows and other custom materials as per you requested.

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.

How it works?

 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.

We support a number of file formats to ensure we always meet the requirements of our clients. This includes popular formats of .stp, .sldprt, and .psm/.par. moreover, we make sure to work with our clients to the end so they get their desired result designed to utter perfection. This is the value we stand for.

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.
