According to Cheto, the all-in-one concept enables moldmakers to perform multiple operations with one setup, including deep-hole drilling, radial drilling, milling, tapping and boring. "It is not simultaneous machining like a five-axis CNC, but the Cheto has seven movements," Hill says. The pivot point of the head is at the very front of ...

Firstly, the end mill moves along a helical path. It means that the milling center must combine the vertical z-axis movement and the horizontal x-y axis. This makes the NC program very complex to write manually, however, a lot of CAM-systems have adopted helical milling as one of the strategies. The geometry of the chip consists of two zones ...

The milling machine is the workhorse of the machine shop. In essence, a vertical mill is like a drill press except it is fitted with sturdy bearings capable of handling side as well as end loads. Normally up to 85% of machining jobs will require a mill rather than a lathe. Unlike a lathe that spins the material, a mill holds the material firmly ...

Drilling produces a round hole in a workpiece. A tapping or drill press machine performs drilling operations. However, drilling can also be handled with a milling machine. When machining a workpiece, chips are the waste material produced during the machining process. The way the drill bit is shaped enables chips to fall away from the workpiece.
