Durability
Japan's premier grinding machine manufacturer employs advanced technology suitable for machining medical guide wires, shafts, pins, rollers, sleeves, rings, slender shafts, thin-walled components, simple stepped shafts, and multi-stepped small shafts. Materials include ceramics, alloy steel, bearing steel, tool steel, mold steel, copper, aluminum, high-temperature alloys, and cemented carbide. Ideal for automotive parts, aerospace, and other industries.
Double V-shaped guide rails + dovetail groove structure, capable of ±5 degrees rotation with feed adjustment precision down to 0.001mm.
Hydraulic drive, continuously variable transmission, and smooth dressing significantly enhance straightness and surface roughness during grinding.
