Sheet Polishing Technology

We can procure even a single sheet

If special metal sheets are needed, they are generally made into the desired thicknesses through the rolling process. In developing and prototyping such sheets, more material and higher cost than necessary may sometimes be required because of constraints in material production lots even if the demand is only for a small quantity.
On the other hand, as we fabricate such sheets through polishing or grinding, procuring only the minimum required quantity becomes possible.

We can handle nonmagnetic materials

We can process even unmagnetizable materials, such as superheat resistant steel and titanium, into sheets by devising a processing method. When rolling a material that is likely to cause work hardening, such as Ti-6Al-4V, the pressurizing force required for processing increases as the material becomes thinner.
Therefore, the material needs to be annealed several times for the purpose of softening it, which causes an increase in cost. Even in the case of such materials, grinding them helps to reduce the generation of additional costs.

We have experience in polishing a sheet of 0.65 (thickness) x 100 x 500 mm with accuracy within a thickness tolerance range of 0.06 mm.
We can also finish sheets through the lapping process in order to prevent scratches from grinding.

Sheet dimensions we have processed in the past
Grinding: t = 0.25 mm
Lapping: t = 0.5 mm (We will accept the challenge of processing thinner sheets.)
