HMC Offers Flexibility in Cutting Capabilities

Kitamura Machinery’s Mycenter-HX500G horizontal machining center, part of the company’s G series of machining centers, is designed for medium to large parts that require flexibility in cutting capabilities. It accommodates workpieces ranging to 31.5" in diameter and 43.3" in height within a compact footprint, and its solid boxway construction enables 2,362-ipm rapid feed rates. The HMC also is equipped with twin ballscrews and motors in the X and Y axes, as well as linear scale feedback on all axes for optimum stability and accuracies of ±0.000079" full stroke and ±0.000039" repeatability.

The machining center is available in two spindle configurations, gun drilling inserts gun drilling inserts either 40- or 50-taper, enabling it to be used for both lighter-duty aluminum applications and those that require higher-level accuracy and exotic part processing. The 40-taper spindle offers speed ranging to 20,000 rpm for fine-finish cutting requirements, while the 50-taper spindle offers 432.2 foot-pounds of torque and speeds ranging to 12,000 rpm for heavy-duty machining. Both spindles are four-step-geared, dual-contact spindles designed for energy efficiency and kilowatt-hour savings of 40 to 50 percent, the company says. HSK spindle designs are also available as an option.

A two-station automatic pallet changer is field-expandable and is coupled with full 360-degree fourth-axis capability with rotary scale for faster, more accurate production per pallet load, the company says. The HMC is equipped with 50-tool “fixed pot&Carbide Drilling Inserts rdquo; automatic toolchanger with upgrade capabilities for as many as 200 tools. The Arumatik-Mi controller is said to enable smoother, faster machining of complex workpieces with the potential to add fifth-axis simultaneous machining capabilities on both pallets.
