Initially offered in an 800 mm size, the HPC-800HP horizontal machining center (HMC) provides large job-processing capabilities for parts up to 51.2" (1,300 mm) diameter and 59" (1,500 mm) high. Its X-Y-Z travels of 57.0" x 43.3" x 49.8". (1,450 mm x 1,100 mm x 1,265 mm) are more typical of 1,000-mm sized machines, the company says. The HMC’s tool delivery system, featuring 0.9-second tool-to-tool interchange and tool queuing that eliminates next-tool wait and an 8-second pallet exchange, is said to reduce downtime. The HMC is offered with a cell and multi-pallet carousel exchange. Further reducing non-cut times are an acceleration rate of 1.5 G, rapid feed rates of 3,150 ipm in the X and Y axes and a 2,363 ipm feed rate in the Z axis.
Good metal removal rates in processing aluminum and a variety of hard metals are achieved by the XT option, featuring a 60 HP (45 kW) two-range geared, #50 taper or HSK-100A spindle with either 6,500 or 10,000 rpm, giving a maximum torque of 845 foot-pounds (1,146 Nm); or the AP option, offering an integral, high speed HSK-63A spindle with either 15,000 or 24,000 rpm. A tilt spindle for five-axis contouring is available in the XT and AP configurations.
The machine’s B-axis table delivers a 25-rpm rotation and a 4,840-lb payload for high speed processing of heavy workloads. Positioning and contouring configurations as well as pallets measuring 31.5" x 31.5" and 31.5" x 39.3" are available.
Editor PickWhy the Surge in HMCs?
Spending on horizontal machining centers is forecast to reach its highest level in more than a decade. Small shops in particular are buying these machines. A shop I recently visited illustrates the reason.
