All specifications of XR HMC series horizontal machining centers adopt the most advanced spindle technology, which has very high axial and radial rigidity, providing strong guarantee for fast and efficient machining. The APC system of the XR HMC series machining center uses four thick and high-precision conical pins for the positioning and locking mechanism of the worktable, ensuring very precise worktable exchange repeatability. The hydraulic worktable locking mechanism can ensure that the worktable can withstand greater loads. The HR HMC series machining center has two fourth axis configurations, each meeting the machining needs of different parts.
