Material heavyweights aluminum plate (20 × 800 × 2300 mm) of (A5052)
Parallelism of 50 μm, finish the flatness 50 μm.

In this way thin but thick with large plate with distortion,
In our company, it is a high-precision large machining centers (VS-100) (maximum processing size 3150 mm × 1000 mm)
Since having both a high processing technology,
Flatness of the bottom, will achieve the parallelism of 50 μm

Thin heavyweights plate of aluminum like airplanes and automobiles, it is widely used in infrastructure industries such as shipbuilding.

Of course, stainless steel, iron, processing of copper, etc. is also possible.
