3 laser melting with milling Galvano system Feeder Spindle

4 You can choose from 3 ways. Laser melting and high speed milling Milling following laser melting in sequence without dismounting Sintered object + measuring surface for the following process Conventional method laser Milling laser Milling +measuring surface

5 2mm Warpage problem Case example 2:Core for connecter(210mm 210mm) Sintered Base plate

6 Before sintered object is dismounted from machine, machined surface has to be made ready at the same time Solely laser melting Galvano scanner Cycle of expansion and contraction Our technology Warpage Misalignment At least machined surface Milling Z Y X Center Unmeasurable state Misalignment between cad data and sintered object on condition that is used galvano The base plate and sintered object are warped by inner stresses. It can t measure accurate dimensions from fiducial surfaces of the plate Z Y X Measurable state
