Tramming Mill Head

This article goes through the process of tramming a mill head.



Tramming is the process of ensuring that the mill head is perpendicular to the mill table in both the x and y axis. The benefits of having a properly trammed mill head are:

•	Ensures that milled surfaces are mutually perpendicular.

•	Prevents a saw tooth patter from forming on milled surfaces.

•	Ensures that tools are perpendicular to the mill table.

The x-axis is defined as the feeding direction of the mill bench (left and right when facing the front of the mill). See: Mill Axis
