What this take-off assumes

• Body blank charged as the round blank, 360mm over the 350mm finished diameter (10mm cutting margin), in 75Cr1 spring steel at 7.85 g/cm3.
• Tip blanks allow 0.6mm across the kerf for finish grinding and 0.5mm on the height for the braze seat.
• Disc yield is geometric: a 58mm usable disc gives 86 blanks at 0.25mm wire EDM kerf and 82 per cent packing. No supplier publishes a tips-per-disc figure.
• One braze operation per tip: 72 tips per blade means 72 brazes per blade.
• PCD area is published twice: 1620mm2 per blade of disc blank, which the yield and the disc price are charged on, and 1182.4mm2 per blade of finished diamond face, after the side relief and the tooth form are ground off.
• PCD disc cost is taken from stock row PCD-58-16-05, an example row, so it is modelled until you enter your own cost.
