HMC for complex large part machining – Kitamura

Kitamura’s new Mycenter-HX800G horizontal machining center delivers precision, accuracy and repeatability required to produce close tolerance parts from the toughest of materials, says the company.

Consistent accuracies of ±0.002mm/Full Stroke and ±0.001mm repeatability are guaranteed, says the company. Net weight of the machine is 28 400 kilograms.

Use of proven techniques such as induction hardened solid box way construction, hand-scraping of all mating surfaces and four-step gear driven spindles all contribute to superior results and stability when machining larger heavy duty parts for the automotive, oil and gas machinery, aerospace and heavy machinery industries.

Solid box ways and high grade Meehanite cast construction provide superior vibration absorption capabilities for improved surface quality, elevating finish capabilities to a higher level, at the same time overall life of cutting tools.

Extended travels of XYZ of 1 550 x 1 300 x 1 400mm showcase Kitamura’s patented twin ballscrew and servo motor technology on all axes, delivering 60 m/min rapid rates on solid box ways. The work envelope is 1 525 mm x 1 550mm.

Easy accessibility for a machine of its size, it offers an easy to access work envelope with a one piece, easy grip sliding doors, large windows and door openings along with easy spindle access. All combine to reduce and simplify operator workload and help to promote a safe work environment.

The Mycenter-HX800G comes standard with a 40kW,12 000rpm four-step geared, dual contact spindle delivering 586 N•m of maximum torque for large drill/tap applications as well as those applications that require heavy material removal, combined with high rpm for fine finish capabilities-in a single set-up.

An optional 8 000rpm high torque spindle is an available option with output max torque of 1226 N•m. The Dual contact design offers the benefits of greater machining rigidity, improved surface finishes, higher cutting accuracy and extended cutting tool life.

The Mycenter-HX800G comes standard with full 360° 4th axis simultaneous machining capabilities needed to machine complex, multi-sided parts, reducing set-up time. In addition, Kitamura’s two-station automatic pallet changer allows for the loading of parts while machining, improving spindle cutting time while allowing for in-process verification of component quality.
