In recent years, five-axis CNC machining centres have made a big splash in the machining field, winning over many manufacturers with their high efficiency and quality features. Five-axis machine tools, that is, on the basis of the traditional X, Y, Z three linear moving axes, add two rotary axes

In deep-hole drilling, small-diameter holes of less than 1 mm are machined using carbide gun drills, whereas holes of 15 mm and above are typically drilled using welded-edge drills, and holes of 25 mm and above are drilled efficiently using indexable-insert drills.

Technical Overview: This patent addresses the problem of difficult-to-remove burrs on plastic parts following CNC machining by designing a specialised milling cutter. A transition section is incorporated to ensure clearance between the cutter shank and the cutting edge, and the design employs a combination of conical and cylindrical cutting edges.

We generally classify manufacturing processes into two types: material removal and material addition. Most of the processes we use involve material removal, although material addition is also practised; this is generally referred to as forming. For example, injection moulding is a form of material addition; however, our focus here is on material removal.
