What is CNC Milling & How Does CNC Milling Work

CNC milling (computer numerical control milling) is a CNC machining process that involves removing material from the workpiece by rotating and moving a cutting tool, such as a milling cutter, and positioning the workpiece properly, to produce or finish a custom CNC machining object. CNC milling technique can be used to shape a part from beginning to finish, it’s best to produce features or definitions as a secondary or finishing process for machined components. The milling cutting tool can be placed horizontally or vertically, but since the numerically controlled milling machines have evolved strongly, moving on several axis, up to 5 axis, allowing much more to movement of the cutting item in addition to the repositioning of the piece.

CNC Milling Process – What is the Process of CNC Milling?

Starting from designing a CNC milling part drawing or geometry with CAD software, then CAM software converts the file to CNC machine program, which can dictate the machine what to do and how to do. CNC milling services apply computerized technique to complete the manufacturing as the following basic production stages:

Designing a CNC Milling CAD model
Converting the CAD model into a CNC milling program
Setting up the CNC milling machine
Cutting small pieces off the block material to obtain approximate shape
Executing the CNC milling operation with higher precision and accuracy

CNC Milling Operations (Types) – What Does A CNC Mill Do

CNC milling service, one type of CNC machining service, is ideal for manufacturing CNC milled parts with high accuracy and tight tolerances in prototype and small/large batch production, which achieved through the following common CNC milling operations.

Plain Milling: also called surface or slab milling, refers to the milling operation utilize plain milling cutters with teeth on the periphery to perform the cutting, the axis of rotation of the cutting tool is parallel to the workpiece surface.
Face Milling: the operation use milling cutters have teeth both on the periphery and tool face, the rotating axis of cutting tool is perpendicular to the surface of the workpiece，generally for producing flat surfaces and contours.
Form Milling: uses form cutting tools or fly cutters for specific purposes, including convex, concave cutters, typically for creating irregular surfaces and contours like curved surfaces.

Angular Milling: also written a angle milling, milling flat surfaces which are neither parallel nor perpendicular to the axis of the cutter.
Gear Milling: the milling process for creating a gear.
Thread Milling: the interpolation of a thread mill around or inside a workpiece to create a desired thread, requires machines capable of moving on the X, Y, and Z axis simultaneously.
Profile Milling: rough or finish mill vertical or slanted surfaces, continuous tool path.
Straddle Milling: machine two or more parallel vertical surfaces at a single cut.
Other milling operations: Gang Milling, Side Milling, End Milling, Saw Milling, Helical Milling, Cam Milling, Milling Keyways, Grooves and Slot.

CNC Milling Machines – What Is A CNC Mill & Types of Milling Machines

CNC milling machine employs a rotating cylindrical tool (milling cutter) held in a spindle to perform the milling operations, for getting a wide array of shapes, slots, holes, and other necessary impressions. As a common Computer Numerical Control machine, CNC mill has the ability to cut in different angles and move along several axes, allows a variety of milling parts features and designs. The workpiece on CNC mill can be moved across the tool in certain direction.

There are different types of CNC mills divided according to the number of axes:

2-axis CNC milling machine: cut holes and slots in the x- and z-axes
3-axis CNC milling machines: added y-axis, can cut vertically and in any direction
4-axis CNC milling machines: add the ability to rotate the x-axis, similar to a lathe.
5-axis CNC milling machines: most complete milling machine, incorporate rotation in both the x- and y-axes.

CNC Milling Materials – What Types of Materials CNC Milling Use?

CNC milling services can work on a wide range of materials for machining different parts:

STAINLESS STEEL

PLASTIC

BRASS

ALUMINUM

SHEET METAL

GLASS

CNC Milling Applications – What is CNC Milling Used for

Bellflower CNC Milling Surface Finishes

Bellflower provides an array of surface finishing services for your metal CNC milling parts to improve the parts appearance, surface smoothness, chemical, corrosion resistance, and other performance.

Painting: refers to an altering surface finishing process, spraying paint, pigment, or color to a solid surface as a colored protective layer, and can be done on metal or non-metal CNC machined components of any shapes, usually applied on aluminum, stainless steel and steel alloy parts. The purpose is to improve aesthetic appearance and prevent corrosion or oxidation.
Passivation: a common chemical surface treatment method for steel and stainless steel, to remove ferrous contaminants or use a light coat of protective material to create a shell for enhancing the corrosion resistance or reducing the chemical reactivity.
Electroplating/Plating: a process of using an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode, to change the properties of the metal surface or build up thickness for undersized parts.
Powder coating/Powder coat: a functional and decorative finish, which is applied as a free-flowing, dry powder, employs electrostatically and then cured under heat, to create a hard finish that is tougher than conventional paint. The main applications including household appliances, aluminum extrusions, drum hardware, automobile, motorcycle, and bicycle parts.
Anodizing/Anodized: an electrolytic passivation process of forming a thin layer of aluminum oxide on the exterior of aluminum CNC machined parts to increase the thickness of the natural oxide layer and protect the metal, as the layer has higher corrosion and abrasion resistance than aluminum.

Polishing: also known as buffing, a process of rubbing the surface of parts or utilizing a chemical action to produce a smooth and shiny surface, make the surface get significant specular reflection or reduce diffuse reflection in some materials.
Black oxide: also known as blackening, gun bluing or hot blackening, a chemical process of forming a black conversion coating on stainless steel, copper and copper based alloys, zinc, powdered metals, silver solder, and ferrous materials, to improve corrosion resistance and minimize light reflection.
Conversion coating: also known as chromate conversion, the coating are used for metals converted to a protective layer through the chemical or electrochemical processes, primarily used as a corrosion inhibitor, decorative finish, or to retain electrical conductivity.
Bead blasting/Bead blast: the process of removing surface deposits by applying fine glass beads at a high pressure without damaging the surface.
Abrasive blasting/sandblasting: the process or operation of propelling a stream of abrasive material composed of high-velocity sand-sizes particles against the metal surface under high pressure with blast equipment like air pressure system, to remove surface contaminants, clean metals or increase a texture, then change the smoothness or roughness of surface.
CNCLATHING also provides grinding, linishing, industrial etching, and more custom metal finishing service for presenting the best effect of your part.
