Service Overview

CNC Milling Service

CNC mills produce parts of nearly any shape from soft metals like aluminum, harder metals like steel, and plastics such as acetal.

eMachineShop offers cost-effective milling solutions whether you need a single part, batch of prototypes, or full production order.

  • 50+ Materials.
  • FREE Shipping in the USA.
  • 100% Quality Guaranteed.
As Seen In:

Advantages

  • Can produce parts of almost any shape
  • Cost-effective for prototyping and short runs
  • High dimensional tolerances are possible
  • Smooth finishes can be achieved

Design Considerations

  • Use shapes that will hold well during machining, like straight edges
  • Milling creates a visible cut pattern on the surface of the material
  • Avoid deep pockets and ensure corners are rounded
  • Avoid flimsy shapes

What is CNC Milling?

CNC Milling is an automated process used to manufacture 2D and 3D parts by removing material from raw stock.

To make a CNC milled part, a block or sheet is placed on a table below a spindle which holds a cutting tool. A computer controls the tool used, the rotation speed and the vertical motion of the spindle, and the horizontal motion of the table. This allows loaded cutters such as drills, taps and end mills to remove portions of the material to create shapes.

What is a CNC Milling Machine?

CNC milling machine

A milling machine is designed to produce premium parts with a high level of detail and finish. It uses rotary tools to cut away at the material by following the instructions from a CAD file to create a part design.

A milling machine computer controls the cutter’s function and coordinates, while minimum human input is required to complete the task. These machines are involved in the mass production of many components from different materials and plastic.

The primary function of a milling machine includes cutting workpieces into the desired shape. Based on the number of axes this machine has, the more complicated the final piece can be. It’s used for copper milling, steel milling, and other materials.

Why Is CNC Machining Service Important?

CNC services and milling machine options enable solutions to many problems. This technology ensures efficient and effective working processes that result in improved manufacturing technologies. For instance, we could hardly imagine cutting metal to produce car parts or aerospace components without custom CNC milling. While possible, this process would be much riskier and could pose a serious threat to people working on-premises.

With the help of computer software, we can access and create high-definition designs that are easily converted into Cartesian coordinates. CNC milling also has a goal to minimize the costs of prototyping.

However, this technology isn’t for industrial purposes only. It’s widely used in woodworking, aluminum machining, prototyping, and modeling, just to name a few.

I haven't had anything made by them, but I've used their software to design some prototypes and get quotes. Maybe soon.

Needed gripper fingers for robot arm; Good final product, great price, accurate to print, fits on the robot, alignment not 100% but within tolerance. Week or so delay from initial due date, as was expected due to complexity of the shape. Overall would have liked notification of delay, need to keep checking back otherwise you aren't notified until it ships, but would use the service again.
