What are the points for attention in flame cutting SM490YA steel plate?

1：Cutting sequence
The cutting sequence, here, mainly refers to the cutting sequence of sleeve parts on SM490YA steel plate. The principle followed is mainly the principle of "from inside to outside, from small to large". The reason is mainly to avoid deformation of small parts and report scrap.

2：Cutting direction
The correct cutting direction should be able to ensure that the last cutting edge can be separated from the SM490YA steel plate motherboard to avoid displacement, resulting in dimensional deviation.
3：Fire point
Under normal circumstances, the fire point of the cutting part should be selected in the middle of the cut part outside the edge of SM490YA steel plate, which is the best. If the distance is not appropriate, it will affect the cutting quality, and even produce waste products, thus causing waste.
