Horizontal vs Vertical Milling: The Differences Explained ...
Bed Mill: A bed mill, on the other hand, moves the material perpendicular to the axis.The bed of the mill moves along the Y and Z axes and the spindle moves along the X-axis, providing a full, 3-axis range of movement. The spindle movement, coupled together with the horizontal movement of the table enables milling of a variety of depths and shapes.
Up Cut Router Bits vs Down Cut Router Bits » Carbide ...
An Up Cut bit is very efficient in evacuating chips up and out of the cut. It will leave a very clean finish at the bottom of the work piece, but will leave a rougher surface on the top of the surface (or the side that the bit enters the work piece). A down cut bit does just the opposite. It is best to use a down cut bit for through cuts, as a ...
End Mills. The Essential Beginners Guide.
Up-cut end mills eject chips towards the top of the workpiece, leaving a cleanly cut bottom surface inside your material. Down-cut end mills do the opposite, they leave a smooth top surface on your material. Compression end mills combine the best of both worlds and produce a smooth surface on both ends of the workpiece when cutting.
