Please master! Slow wire processing data: Cr12 or ordinary steel material, 40mm thick, how long does it take to cut a 20*20 material, and what is the surface finish?

I am in Suzhou, is your piece of material round?

Perimeter * Thickness is calculated like this: Perimeter * Thickness = Volume

Cut one and trim it: Volume * 0.026

Cut one and trim it two: Volume * 0.038 The required smoothness Very high, the tolerance is very strict, just volume * 0.05. This is generally the case for Sodick. Sodick generally cuts a hole with a thickness of less than 20. Rough cutting is 3mm per minute. Fine cutting is 7mm per minute. The second time is faster
