Kitamura Machinery’s Mycenter-HX500G horizontal machining center provides flexible cutting capabilities for medium to large-sized parts. The compact HMC accommodates workpieces ranging to 31.4" in diameter and 43.3" in height. It features a solid boxway construction with rapid feed rates of 2,362 ipm. Twin ballscrews and motors in the X and Y axes plus linear scale feedback on all axes optimize stability. Accuracies are ±0.000079" full stroke and ±0.00039" repeatability.
The HMC is available with either a 40- or 50-taper spindle configuration, making it suitable for either lighter-duty aluminum applications or heavier, accurate processing of exotic workpieces. Both are four-step geared, dual-contact spindles designed for energy efficiency. The 40-taper spindle provides speeds ranging to 20,000 rpm for fine finish cutting requirements, whereas the 50-taper spindle offers 432.2 foot-pounds of cutting torque for heavy-duty machining. HSK spindle designs are optionally available.
The HMC is equipped with a 50-station fixed pot automatic toolchanger, upgradable to 200 tools. The two-station automatic pallet changer is field expandable and coupled with 360-degree fourth axis capability and a rotary scale for faster, more accurate production per pallet load. The Arumatik-Mi controller offers smooth, high-speed processing with the potential to add fifth-axis simultaneous machining capabilities on both pallets.
Editor PickVideo: The Impact of a Horizontal Machining Center
A small shop describes the efficiency gains it is seeing now that it has a horizontal machining center instead of solely verticals. One of the shop’s leaders talks through processing of parts then and now.
