The Engineering Challenge

Background & Bottleneck

Achieving a 12.99 mm bore diameter with a 13-micron tolerance (±0.0065 mm) at an extended depth of 70 mm in an aluminum steering housing. Standard catalog boring bars suffered from deflection, chatter, and thermal drift, resulting in an inadequate CPK of 0.70 and high component scrap rates.

Q Tech Engineering Solution

The Tooling Architecture

Q Tech Products engineered and delivered a specialized micro fine boring bar within just one week. The tool featured a dial-calibrated micrometer adjustment mechanism (0.002 mm vernier resolution), high-pressure internal coolant ports aimed precisely at the cutting interface, and an optimized alloy body geometry to dampen vibration at the 70 mm overhang.
