Precision milling is a machining process usually carried out cold, using CNC machines: this is why it is often also called CNC milling.
CNC machines work in cycles previously set on a computer, which records the number of products to produce and does so completely autonomously once the operator sends the input.
Precision milling, or CNC milling, can handle large volumes while saving a great deal of time. This makes it one of the most cost-effective machining processes, especially for large quantities and small parts.
What does milling involve?
Milling removes chips with a tool that rotates around its own axis while the workpiece is fed. The tool must therefore rotate while the workpiece simultaneously moves in translation.
The work can take place in two stages: roughing, which removes metal quickly and coarsely, and finishing, which removes the remaining excess. There are different types of precision milling: cylindrical, face or slitting, conical or spherical. Each is suited to a specific need.
Precision milling: all the benefits
The benefits are many: first, the machine works completely autonomously, because once the input is sent, the work proceeds in fast cycles; with CNC milling, production increases significantly, especially when a large number of finished products is needed quickly; finally, the milling machine can work many materials and sizes, whatever their surface.
