Milling is one of the machining methods and is a permanent element of machining various types of channels, grooves, threads, surfaces and teeth. During cutting, only part of the blades work in succession one after the other. Milling involves the contact of the device with the workpiece, where a special tool is responsible for the rotary movement, and the workpiece is responsible for the feed movement.
Milling techniques due to the way the blades move:
• Concurrent milling - the direction of movement of the workpiece is in accordance with the direction of work of the blades, and the thickness of the machined layer is the largest at the beginning of the work of the blade and zero at the end of the work
• Reverse milling - the direction of movement of the workpiece is opposite to the direction of the blades, and the thickness of the cutting layer increases from zero to the maximum value
Milling techniques due to structural division:
• Full milling - called three-sided, involves working three surfaces simultaneously
• Incomplete milling - called double-sided, involves the simultaneous creation of two machined surfaces
• Free milling - called one-sided, involves the creation of one machined surface
Technological division of milling:
• Cylindrical - called circumferential, occurs when the milling axis is located parallel to the surface being machined
• Face - it occurs when the milling axis is perpendicular to the surface being machined
• Oblique - occurs when the cutter axis forms an angle of 90° with the surface being machined
A milling machine, i.e. a special machine tool, is used for machining various types of elements and surfaces. When machining with a milling machine, a milling cutter is required that rotates for machining. At JARD, we work on industrial CNC milling plotters. This modern plotter, depending on the configuration and additional equipment, can be designed for processing both plastics as well as light and steel alloys.
