Finish boring operation
For most lathe boring applications, tolerances greater than ±0.010 in (±0.25 mm) are easily held. Tolerances from there down to ±0.005 in (±0.13 mm) are usually held without especial difficulty or expense, even in deep holes. Tolerances between ±0.004 in (±0.10 mm) and ±0.001 in (±0.025 mm) are where the challenge begins rising. In deep holes with tolerances this tight, the limiting factor is just as often the geometric constraint as the size constraint. In other words, it may be ea… WebMay 1, 2011 · For any finish boring operation, whether it is a relatively soft material such as aluminum or a hard material like tool steel, applying an insert with the correct edge radius is critical. Normally, a sharp cutting edge is necessary. “Sharp inserts are good for finish boring because they create really low cutting forces,” Godfrey said.
