3axis Mills. 3axis vertical mills allow the table to move in the X and Y directions. With these machines, the workpieces can be positioned relative to the cutting tool. The operator can then add the Zaxis by lowering the cutting tool. CNC tools ensure simultaneous movements of the three axes, offering the needed flexibility for your needs.

I had exactly the same problem with work slipping off angle plates in the vice, so I made a matching pair of 'vee plates' to use on the mill vice which gets over the slippingoff problem quite neatly. They work well on the surface grinder too. The plates have dowelled and screwed guides which can be changed over for either 45deg or 15deg angles.

On a vertical mill, the rotary cutting head has a vertical alignment, causing the spindle to move up and down along the Zaxis while the machine is in operation. As the spindle moves, the cutters work to remove material as the rest of the machine moves and shifts along the Xaxis and Yaxis to continuously position the object for further cutting.
