Latest Patents

Shirai's latest patents include the pin mirror cutter, which features a throw-away tip mounted on a first tip mounting seat. This throw-away tip is designed with cutting edges formed at the intersecting ridgeline parts between a pair of oppositely disposed long side faces of a substantially trapezoidal flat-plate-shaped tip body. The upper and lower faces of the tip body are also integral to its design. The thickness direction of the tip body is approximately aligned with the radial direction of the cutter body, allowing for curved edges formed in acute corner parts of the tip body for effective cutting. Additionally, the tip is mounted on a second tip mounting seat of the pin mirror cutter, ensuring that the thickness direction of the tip body aligns with the axial direction of the cutter body, which provides curved edges formed in obtuse corner parts of the tip body for enhanced cutting performance.
