What Is The Difference Between Face Milling, End Milling And Peripheral Milling?


Face milling, peripheral milling, and end milling are milling processes that differ in many ways. So read this blog post to tell the difference between these three milling modes:

Cutting Method

Face milling is to start processing on the surface of the machined parts, and it performs translational cutting work on parts or components. Generally speaking, its translation operation makes the workpiece create a smooth and exquisite surface.

End milling focuses on the side of the workpiece in the cutting method. It is the detailed construction of grooves, threads, and contours for part machining in a manner that engages the cutting components.

Peripheral milling takes cutting the peripheral part of the workpiece as the main processing method.It has the advantage of creating grooves that have the effect of merging several pieces.


Blade Style

Face milling uses disc milling cutters with multiple cutting edges. And the machinist cutting edge is easy to assemble and replace when broken. Additionally, it increases efficiency when removing large areas.

The tools used in end milling are usually fluted and cylindrical-style milling cutters. The mounting position of the cutting edge of the end mill is on the periphery of the end face. End milling tools provide versatile operations specifically for feature-creating machining.

Peripheral milling cutters have a peripheral tooth design. The tooth design for perimeter milling is able to handle sharp workpiece edges. It is advantageous to design the external thread and the external contour at the machined edge.


Cutting Direction

Face milling is the working angle at which the tool is perpendicular to the workpiece. The surface of the workpiece is milled using rotary cutting.

End milling is the cutting of parallel surfaces by the end mill cutter and the machined part.

Perimeter milling is a rotary cutting direction similar to milling, but the cutting position is around the workpiece.

The above is the difference between the two different processes. This blog post provides directions for manufacturers to choose from the cutting method, tool, and working orientation. The comparison can help the workpiece choose the most effective technology.





What Is The Process Of Face Milling?


By familiarizing yourself with the operation process of flat milling technology, you can better understand the charm of this process:

Fixed Workpiece

The fixture is fixed on the face milled part so that the angle and precision of the cut are accurate.


Select Milling Cutter

Then choose the right and cost-effective cutting tool and flat milling cutter type for different milling applications.



Secondly, accurately set the cutting speed or feed per tooth of the lathe milling to ensure that the face milling accuracy is up to standard.


Chip Removal

Carry out waste removal during the operation, and properly add coolant to the machine tool to assist.



Finally, check whether the face milling products meet the production standards in an all-around way to avoid unnecessary losses due to shipment.
