Inconsistent holes on cast aluminum?
Cast aluminum work piece? What is the most common problem you could face? We believe it’s all about hole diameter and hole distance are inconsistency.
Due to the character of cast aluminum, such as automobile, motorcycle and bicycle engine parts, the hole diameter and hole position are inconsistency, in order to get H7 tolerance finishing hole and right position, we recommend 99146 NineBore boring tool.
In this video we show you 3 concepts.
1. The spindle speed can up to 10,000rpm for boring Ø10mm hole which other brand can only up to 2500 rpm, the machining time is 4 times faster. [📽 00:28]
2. H7 hole accuracy. NineBore could do rough boring and fine boring in one operation by using CNC code G85, total machining time 4.75 seconds (Ø10mmx10mm depth). Down boring to get right pre-hole diameter and back boring to get H7 finishing hole tolerance. [📽 00:40]
3. Resulting from above, the hole distance is correct and no more inconsistence. [📽 00:56]
