Quoting bar

From the drawing to a cut length, without leaving the condition open.

Bar is bought to make a part, so the drawing is the starting point. Diameter, cut length and condition all follow from what the part is, and a quotation given without them is a price for something else.

Why cut length changes the price

The usable length per cut decides how many parts come out of a bar and therefore the piece price. A customer who sends the finished part length alone is quoted against an allowance we had to guess; sending the machining allowance removes the guess.

What the quotation confirms

Maximum single lengthAt that diameter and grade
ToleranceOn the diameter band ordered
UT classThe class we can meet on that section
ConditionRecorded so the certificate matches the order
