CNC machining processes

At IN3DTEC, we use advanced 3 axis, 4 axis and 5 axis CNC equipment to offer you more than 60+ machined metals & plastics, our CNC machining services include CNC milling, CNC turning, EDM, and wire EDM, surface grinding, and much more.

Our CNC machining abilities also complement our 3D metal printing service making us a great one-stop shop for your advanced designs.

We make your machined metal or plastic parts and get them to your door in as fast as 3 days.

CNC Milling

CNC Milling Service is the process of removing material from a solid blank to create a finished or semi-finished shape.

With our 3 & 5 axis CNC machines, we can produce parts with complex geometries with high accuracy down to +/-0.01mm.

CNC turning

CNC turning service produces parts with cylindrical features by removing material from metal or plastic rods using cutters, center drills or live tooling.

It’s also ideal for larger production runs when coupled with an automatic bar feeder that provides an uninterrupted supply of raw material into the machine.

What metals can be machined by CNC router?

Aluminum

Aluminum is considered to be the most popular and cost-effective metal when it comes to CNC Machining. This is because it has high machinability, lightweight but strong.

Al6061 is an economical grade that offers fantastic workability and machinability. It is seen as a general-purpose grade material.

Stainless Steel

Whilst it does not have the same high machinability as Aluminum, stainless steel still does maintain good machinability. More robust and with more chemical resistance than Aluminum makes, it is also a trendy material in CNC machining services.

SS304 and SS306 grades are the two most commonly used ones.

Alloy Steel

Alloy steel is a low alloy steel that contains manganese, chromium, and molybdenum. It has high fatigue strength toughness, and impact resistance properties, making it an attractive alloy for many applications and industries. This alloy is more cost-effective compared to stainless steel.

Titanium

As the most expensive metal in the CNC metals family. Titanium…

How to select the right CNC plastics?

ABS is one of the most common thermoplastic materials offering good mechanical properties, excellent impact strength, high heat resistance and good machinability.

Polycarbonate is a thermoplastic with high toughness, good machinability and excellent impact strength (better than ABS). It can be colored, but typically it is optically transparent, making it ideal for a wide range of applications, including fluidic devices or automotive glazing.

POM is commonly known with the commercial name Delrin, and it is an engineering thermoplastic with the highest machinability among plastics.

POM (Delrin) is often the best choice when CNC machining plastic parts that require high precision, high stiffness, low friction, excellent dimensional stability at elevated temperatures, and very low water absorption.

Surface Finishes in CNC Machining Service

As machined

~125 RA µin (3.2 RA µm). Minor tool marks will be visible on the part.

Anodizing

It helps to resist corrosion, increase surface hardness, improve resistance to wear, and dissipate heat. Available in a variety of colors. Type II, Type III

Painting & color matching

We can match the standard Pantone color, paint it into glossy, matte finish, and more options.

Blasting & polish

Bead blasting & Electropolishing add a uniform smooth surface on a machined part. Removing all the tool maks.

Black oxide

Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.

Brushing

It helps to resist corrosion, increase surface hardness, improve resistance to wear, and dissipate heat. Available in a variety of colors. Type II, Type III

Vapor polishing

This is a specialized treatment for achieving optical clarity on polycarbonate (PC) plastic. This method is ideal for achieving an extremely clear surface on complex geometries or hard to reach areas.
