How to choose the blank of the quenched chrome bar

Determination of the shape and dimensions of the blank:

1, the shape of the blank

According to the processing precision requirements of some parts drawings, the scale tolerance grade of forgings is 8-12 grades, and because the quenched and tempered chrome bar are selected for small batch production, consider selecting cylindrical blanks.

2, rough wood scale

Because the blank is made by free casting, according to the scale requirement of the quenched chrome bar parts drawing and the practical processing requirements, the dimensions after casting are: diameter 62mm, length 1150mm, check the technical manual, determine the scale of the blank is 80mm diameter, The length is 760mm.
