Fine Blanking Tooling (Main Punch&Die) Standrad Process

Item	Process	Datum	DATA Standard	Fixture	Process Information
1	Mat'l				According the product size, using the hard materiel to manufacture, and arrangement the product shedule and confirm the material hardness.
2	Milling	Sweep Edge	Reference Angle	pressplate	According the part material drawing to drill the threaded hole, and chamfer C1.5
3	Punching	Sweep Edge	Reference Angle	pressplate	According the drawing to drill the hole for wire cutting process.
4	Wire Cutting	Sweep Edge	Reference Angle	pressplate	Firstly check the machine accuracy to wire cutting a material, after confirmation, then to manufacture, bore, profile roughness, and finish work bore and profile,boring tolerance is (+0/+0.005), profile is (-0/-0.005). Wire cutting is 0.002mm manufacture method to make sure the upper and lower both side are the same, in the mid. is indent 0.003.


5	Grinding			vice	Checking the wire cutting vertical, to manufacture the thickness according the drawing, make sure the end face with the wire cutting face perpendicularity is within 0.01, and grind the lint.

6	WEDM		Bottom Hole	magnetic	Manufacture the thread hole
7	Bench Work				Deburr, carbonization zone, and prohibit chamfer.
8	Inspect				Full check and remark the measured data
