Solution
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.
P Series High-Precision CNC Lathes for Micro Machining
The P Series are high-precision CNC lathes developed for micro machining. They achieve excellent surface roughness at the Rz sub-micron level in aluminum facing, making them suitable for high-precision components such as lenses and mirrors, as well as other applications requiring superior surface quality. With a rigid, thermally stable structure, the machines provide stable precision machining. The P Series is also widely used in automotive mass production lines, offering the reliability and durability required for 24-hour operation.
