Practical Automation with Multi-Tasking Machines Designed for Automation

Automation of 5-axis machining centers and lathe-based multi-tasking machines can be confidently entrusted to Hasegawa. While automation of multi-tasking machines often leads to high costs, Hasegawa’s compact machines—designed from the outset for automation—enable cost-effective solutions. The PM Series features a structure that minimizes maintenance space on both sides, allowing automation solutions typically handled by system integrators to be implemented in-house. The CW Series offers the same high compatibility with automation, providing flexible options such as gantry loaders or collaborative robot configurations to match on-site requirements.

Maximizing Productivity Within Limited Floor Space

When selecting equipment, productivity relative to installation space is a critical factor. Maximizing production capacity per square meter within a limited factory layout directly leads to stronger competitiveness in manufacturing. Hasegawa has thoroughly pursued this concept by offering compact multi-tasking machines that generate high added value even in limited space. By enabling multi-process machining, process integration, and automation within a small footprint, efficient production layouts can be achieved. This approach is especially effective in space-restricted environments such as urban factories or second-floor installations.

Stable Automated Handling with a High-Rigidity Gantry Structure

Hasegawa loaders use FANUC NC control and a gantry structure directly mounted to the machine’s cast-iron frame, ensuring high rigidity and stable operation. Models support workpieces from 500 g up to 3 kg, allowing selection according to production scale and application. On twin-spindle machines, front and back machining or simultaneous operations can be performed, contributing to shorter cycle times and process integration. Combined with the loader, unmanned operation and long-term automated running become easy, supporting night shifts and labor savings. Flexible customization such as dedicated grippers, part flipping units, stockers, and in-line measurement systems is also available for mass production.

High-Precision and High-Efficiency Spherical Machining by Single-Path Cutting

This advanced technology enables continuous single-path cutting of spherical surfaces, achieving high-quality machining in a shorter time with lower cutting load compared to conventional multi-step processes. Cutting, burnishing, and polishing can be completed in one setup, consistently achieving sphericity under 5 µm and surface roughness below Ra 0.1 µm. A rigid structure and optimized balance extend tool life and reduce variation. Compatibility with raw material machining and automation supports stable mass production, labor savings, and cost reduction.

High Vibration Damping and Dimensional Stability from a Symmetrical Design

The CW Series uses high-strength cast iron and a fully symmetrical left-right layout with reinforced rib structures to secure sufficient cross-sectional area and high rigidity. This design makes lateral vibration difficult to transmit, so under normal machining conditions, vibration has little effect on the machined surface. This structure is being analyzed and evaluated through joint research with Nihon University and Fukushima Prefecture, and experimental data has confirmed its excellent vibration damping performance. In addition, the symmetrical structure stabilizes thermal movement and reduces dimensional changes caused by temperature variation. This ensures stable dimensional accuracy even during long-term operation and mass production.

Vibration cutting (spindle oscillation)

Oscillation Cutting (Vibration Cutting)
Reliable chip control even on Hasegawa’s compact machines
Oscillation cutting synchronizes periodic X and Z axis vibration with spindle rotation, breaking chips into smaller pieces. By introducing a brief non-cutting interval, chip entanglement and evacuation issues are reduced. Amplitude and cycle settings can be easily adjusted in the program.
Key benefits include reduced chip tangling, more stable deep-hole and small-diameter machining, improved tool life, and fewer issues during unmanned or night-time operation.
Despite being compact, Hasegawa machines maintain the rigidity, control response, and synchronization accuracy required for stable oscillation cutting. The structure also incorporates chip evacuation considerations, delivering performance comparable to larger machines.
Users have reported improvements such as eliminating deep-hole clogging, more stable night-time operation, and extended tool life on difficult-to-cut materials.
