The machining center is a CNC machine with multi-purpose functions, while the horizontal machining center ( HMC ) is a machining center whose main axis is parallel to the workbench and the floor, has better chip removal ability, horizontal direction design makes the chips fall automatically, and there is no need to manually remove the chips on the workbench. The horizontal machining centre is capable of accommodating two pallet changers, allowing unattended production work and reducing part cycle times.
