Okuma has developed the “MS-320H” compact horizontal machining center (HMC), which features a new design with an A-axis table on a vertical surface. Officially launched on November 5 at the opening of JIMTOF2024 (The 32nd Japan International Machine Tool Fair), this HMC minimizes chip-related problems and enables extended unmanned operation. For the electric vehicle and semiconductor manufacturing equipment industries, Okuma is pushing new automation solutions for machining small parts.
Okuma’s booth at JIMTOF2024, one of the largest at the event, attracted considerable attention, with the MS-320H standing out. This HMC with a BT40 spindle and four-axis configuration is mainly optimized for machining compact components up to 250 mm in size.
Dr. Atsushi Ieki, President of Okuma, described the MS-320H as “a horizontal machining center with a completely new concept and machine structure.”
Unlike typical four-axis HMCs with a B-axis table on a horizontal plane, the MS-320H positions its A-axis table vertically. This innovative configuration allows chips to fall directly off the table and fixtures, preventing chip buildup. Combined with a center trough design that collects chips from the entire machining chamber, the MS-320H has minimized chip-related troubles.
These features enable extended unmanned operation and improve automation compatibility.
While traditional horizontal MCs often require pallet changers for automation – requiring additional floor space for multi-pallet setups – the MS-320H can work seamlessly with loaders and collaborative robotic systems. This flexibility allows manufacturers to build space-efficient automation systems that can be adapted to various production needs, from high-mix, low-volume production to high-volume manufacturing.
At JIMTOF2024, the MS-320H was exhibited with a loader and attracted a great deal of interest. Many visitors peered into the machining chamber to inspect its distinctive A-axis table.
The main target of the MS-320H is small components for markets that are expected to grow in the future, such as electric vehicles and semiconductor manufacturing equipment.
President Dr. Ieki emphasized the machine’s versatility, saying, “These industries require flexible production systems. The MS-320H can be adapted to different production styles, including automation, and is able to provide customized solutions that are like dedicated machines for each customer”.
Okuma introduced the MS-320H at JIMTOF2024 as a new automation solution for companies struggling with labor shortages and chip management challenges. The company plans to start with an annual sales target of 100 units, with a long-term goal of 300 units per year. The base price starts at 30.5 million yen (excluding tax).
