Horizontal Machining Center Work Envelope Optimized for Cutting Molds

The leadership team at Okuma America Corp. introduces the MA-8000H for the first time in North America, the latest addition to the company’s horizontal machining center (HMC) lineup that has an optimized working enveloped for cutting molds and parts. Okuma says the new CNC machine was designed for greater productivity when manufacturing large parts, without compromising machining capacity, reliability or accuracy.

The MA-8000H HMC is said to be a versatile machine designed for a wide range of machining applications from heavy-duty to high-feed machining. The machine’s work envelope and expansive travel ranges (X-axis: 1,400 mm, Y-axis: 1,200 mm, Z-axis: 1,350 mm), coupled with a highly rigid bed and cast-in ball screw mounts for highly accurate drive and positioning, make the MA-8000H ideally suited to cut medium-to-large workpieces. Additionally, powerful spindle options effectively handle materials across the metal spectrum.

The MA-8000H is engineered with Okuma’s proprietary Thermo-Friendly Concept, a feature that is said to practically eliminate thermal deformation during the machining process. The machine also includes an integrated thru-spindle coolant suction feature to mitigate excess coolant usage when machining functions have abated. Additionally, the machine is equipped with an enhanced chip evacuation system with in-machine washing and a new sludgeless coolant tank design that reduces coolant replacement cycles and tank maintenance needs.

At IMTS the MA-8000H is equipped with Okuma’s next-generation energy management technology — ECO suite plus. This new smart technology helps to manage energy usage of the machine and peripheral devices, ultimately reducing CO₂ emissions, according to the company. The ECO suite plus technology is now available on all Okuma machines.

Okuma adds that the MA-8000H has been thoughtfully designed and is well-suited to adopt automation systems such as automatic pallet changers (APCs), flexible manufacturing systems (FMS) and a variety of robotics to enhance productivity further.
