Design for manufacturing
Checks from the model, the drawing and the estimator.
Bore tighter than the rules price (Shaft bore)Desk review
Ø12 +0.005/0 and 0.005 runout are tighter than the automatic range, so the quote desk prices them with the shop. Expect a quote within one business day.
From the drawing
A looser bore would price automaticallyAdvice
If Ø12 H7 (+0.018/0) works for the encoder, the quote could go out on the rules alone.
