Fineblanking Economies
Fineblanking is a process that provides parts with smooth edges and high accuracy. Because of the stability and precision of the process many secondary operations can be eliminated. These include:
Grinding
Milling
Broaching
Reaming
Gear Hobbing
Forming
Shaving
Leveling
Fineblanking can produce, in a single step, a part that would require multiple operations, set-ups, and man-hours using other processes. As a result Fineblanking is frequently the lowest total cost option.
Basic fineblanking process
To manufacture parts in fineblanking quality, the following conditions have to be met:
fineblanking press
fineblanking tool
malleable material
Before the material is actually fineblanked, it is firmly clamped, so
that it can flow only in cutting direction. On the outside of the
component''''s cutting line, the material is sandwiched by the die and
the V-ring plate (stinger), inside by the punch and counter punch.
The clearance between punch and die measures only a few 100ths of a mm
(1/1000 of an inch) and the cutting speed is relatively slow.

经济精密冲裁
精密冲裁是一个能制造出光滑边缘及有较高精度的零件的工艺方法。因为这种加工方法的稳定性及所能达到的精度，很多的二次工序能得以免除。包括：
磨削
铣削
拉削
铰
滚齿
成形
剃齿
校直
精密冲裁可以用一个工序就制造出一个零件，相反，利用别的工艺方法就可能需要多工序，装夹，人时来完成，因此，精密冲裁通常是一个制造费用最低的方案。
精密冲裁的基本工艺
要制造出一个具用良好的冲裁质量的零件，以下条件必须符合：
精密冲裁冲床
精密冲裁模具
良好延展性的原料
在工件冲裁之前，发须先装夹好，以便其应力流能朝着切断方向。在工件外切断外边缘，材料受模具及V形模板的夹制，而在内缘则受到上下冲的影响。上下模之间的间隙通常只有100ths/mm(1/1000in)，并且，冲切速度相对来说也是比较低的。
