What is the difference between a CNC router versus a CNC mill?
CNC mill. CNC mills can perform nearly all the functions of the CNC router, but there are some differences. CNC routers are for softer materials, and mills get used to cut hard materials. Instead of a stationary table, the CNC mills move in X and Y configuration, with the spindle moving on the linear axis above the workpiece. CNC mill highlights
What Is a Temper Mill? (with picture)
The metal forming method at a temper mill involves rolling the sheets of steel through what is known as a cold reducing process or temper pass. This increases the density of the steel by reducing its overall thickness between usually 1.5% to 2% without allowing the steel to spread out while under pressure.
