850 Horizontal Machining Center

A horizontal machining center (HMC) is a machining center with its spindle in a horizontal orientation. This machining center design favors uninterrupted production work. One reason for this is that the horizontal orientation encourages chips to fall away, so they don’t have to be cleared from the table. More significantly, the horizontal design allows a two-pallet workchanger to be incorporated into a space-efficient machine. To save time, work can be loaded on one pallet of a horizontal machining center while machining occurs on the other pallet.

CNC Milling Machine 3 Axis VMC1260

3-axis CNC machining evolved from rotary filing. With a 3-axis CNC machine, the workpiece is stationary while the cutting tool moves across the X-, Y-, and Z-axes. The X-axis (vertical axis) is left to right along the lathe table, the Y-axis (horizontal axis) is from front to back of the table, and the spindle that drops from the top marks the Z-axis (depth). A standard 3-axis CNC milling machine has a table that moves the part to provide one or two planes of movement and a tool that provides the other one or two planes of movement. 3-axis machines are ideal for simple tasks that don't require intricate detailing or depth. As such, it is one of the most preferred techniques for creating mechanical parts for automation.
