Kitamura Machinery’s Mycenter-HX300iG/400 expands the company’s small-footprint HMC offering, providing heavy-duty cutting, accuracy and reliability. For its size, the machine is still designed with a large work envelope, with a maximum workpiece diameter of 500mm, a maximum workpiece height of 745mm, and XYZ axes measuring 460mm by 510mm by 560mm, respectively. A 400mm table option offers additional workholding possibilities.

The 22kW, 15 000rpm, 40 taper, direct-drive, dual-contact spindle is said to be capable of handling a variety of exotic materials. A 20 000rpm dual contact spindle is also available.

The fully integrated fourth-axis rotary table, equipped with an integral drive motor, enables rapid indexing speeds of 150rpm (54 000 degrees per min.) reducing out-of-cut time, eliminating backlash and providing positioning accuracy of ±2 arcseconds.

An expandable 50-tool automatic toolchanger allows for the addition of up to 200 tools as needs change. The ATC is fixed-pot, which ensures that tools are always returned to the same pot and that the next tool to be used is kept in a stand-by pot. A 1.3-sec. tool-change time contributes to the reduction in overall cycle time made possible by the machine, the company says.

The Mycenter-HX300iG/400 provides positioning accuracy of ±0.002mm with 67-million-pulse encoder technology for better finish accuracy. To accommodate a variety of metal cutting requirements, the machine offers rapid traverse rates of 60m/min, ballscrew cooling, and 10nm optical linear scale feedback in the linear axes.
