SAKURAI has released an updated version of its robotic machining system, the SAKU270F, targeting large workpiece applications in the EV and aerospace sectors. The system combines a FANUC high-payload robot with a proprietary in-house spindle, offering a compact alternative to large machine tools.

The SAKU270F is a robotic machining system built around FANUC’s R-2000iC/270F, a robot with a 270 kg payload capacity, fitted with a spindle developed in-house by SAKURAI for cutting operations.
Key specifications include:
– Robot arm stroke: 1,500 mm (X), 1,000 mm (Y), 500 mm (Z)
– Maximum spindle speed: 15,000 rpm
– Tool magazine capacity: 12 cutting tools, supporting drilling, milling, and related operations
Machining programs are created in CAM, converted into robot programs, and verified through motion simulation before cutting operations are executed.
Large workpiece machining has traditionally required gantry machining centers or five-face machining centers, which require significant space and capital investment.
The SAKU270F is positioned as an alternative for applications where such equipment is difficult to introduce.
SAKURAI emphasizes that the system should be used with an understanding of its differences from precision-grade machine tools.
“As long as you are working with a robot, achieving top-tier positioning accuracy and machining accuracy is not a realistic expectation,” said Hirofumi Morishima, General Manager of the Machine Tool Division.
This positioning shows that robot machining is intended for applications where cost and space constraints are important.
Trade shows are SAKURAI’s primary channel for product promotion.
While the SAKU270F was originally conceived for aluminum alloy machining, exhibition appearances have generated inquiries for resin and cast iron applications as well — a sign that the addressable market may be broader than initially anticipated.
SAKURAI is targeting delivery of the first unit within the current fiscal year. “Interest in robot machining from aerospace customers has been growing recently,” said Morishima. “If demand for aerospace component machining continues to expand, I would expect demand for robotic machining systems to follow.”
Hirofumi Morishima, General Manager of the Machine Tool Division at SAKURAI: “The SAKU270F’s strength lies in the knowhow we bring from building dedicated machines”
SAKURAI operates both as a builder of dedicated machines for the automotive industry and as a precision parts manufacturer. The company developed the first generation of its robotic machining system around four years ago in response to growing demand for large workpiece processing.
The SAKU270F was released in November 2024, incorporating a FANUC robot following refinements to the earlier model. SAKURAI developed the system in collaboration with FANUC. “Working with FANUC, a domestic manufacturer, makes coordination straightforward. We developed the system together, each bringing our respective technologies to the table,” said Morishima.
The company’s strength lies in its ability to design and propose peripheral equipment — tables, jigs, and related fixtures — tailored to each customer’s requirements, drawing on know-how from dedicated machine design and automated line construction. It also has strong expertise in robot operation and system setup.
SAKURAI clearly positions the SAKU270F in relation to conventional machine tools. By clarifying its limitations in accuracy, the company presents robot machining as an option for applications where flexibility and cost are prioritized.
