What is CNC Milling?

 

CNC (Computer Numerical Control) milling is a subtractive manufacturing process where material is removed from a solid block using rotating cutting tools. It produces high-precision parts with tight tolerances and excellent surface finishes. CNC milling is suitable for metals, plastics, composites, and more.

 

  • High precision and tight tolerances
  • Multi-axis machining (3, 4, or 5-axis)
  • Suitable for prototypes, small-batch, or production parts
  • Wide material compatibility
  • Fast turnaround and consistent quality

First time using and I must say the quality for the part is excellent. The ordering and quoting was very good on the web site. The shipping and turn around time is 1st Class. I would recommend to anyone wanting a top quality part (or parts) and outstand shipping.

Ed Burks

Exceptional service, always willing to work with the customer to ensure parts are built to spec. Quick, reliable turn around, high quality and reasonably priced CNC/3D Printed parts.

Ron Miranda

Working with in3dtec was great. The communication was really good - they responded always fast and to my satisfaction. Their statement about competitive prices is totally true and the quality is nothing to complain about. Hope in3dtec will continue with their great work. I will definitely order again.

Daniel Kuehnle

My experience working with the team at IN3DTEC was wonderful. The team was easy to work with and provided me with useful feed back about my design. Also the price was just right.

How CNC Milling Works?

 

CAD & CAM Preparation – Import CAD model and generate toolpaths using CAM software.

Setup Material – Secure the workpiece on the milling machine.

Milling – Rotating cutters remove material layer by layer.

Quality Check – Inspect dimensions and tolerances during and after machining.

Finishing – Optional polishing, coating, or secondary machining operations.
