Material for Wire-Drawing Dies SUMICRYSTAL CD
■ General Features SUMICRYSTAL CD has optimized crystal orientation and shape as a material for wire drawing dies. Realizing excellent performance through high quality and stability.
■ Features (1) High quality with very low variance. High-quality crystal with minimal impurities, chipping and distortion is used to achieve high, stable wear resistance. It also eliminates the need for inspection and selection of raw stones required for natural diamond. (2) High fracture strength Resistant to fracture and cracking during wire drawing. (3) Accurate crystal orientation (111) is used on the top and bottom surface, limiting crystal misorientation, which causes variance in tool life, to within 1°. (4) No grinding needed for top and bottom surface The top and bottom surface are cleaved to form parallel surfaces, eliminating the need for grinding of the top and bottom surface.
■ Standard Type The outside is machined by laser, achieving a consistent shape for easy setting. Mounting pressure is applied evenly, ensuring sufficient strength even for small volume. Ideal for applications with limited dimensions, such as nozzles and wire guides. ■ Standard Items Dimensions (mm) Shape Cat. No. Stock L T
