Project: Broaching of an Aluminum Lower Receiver Cavity
Industry: Firearm Industry
This project demonstrates our expertise at providing precision broaching that meets the tough demands of military and firearms industry. Illinois Broaching Co., Inc. produces these lower receiver cavities in production volumes that average 3,750 pieces per week. At the start of the project, we fabricated precision broach tooling and fixtures that would perform accurately with repeatability on these 7075 T-6 forged aluminum rifle components. We are able to broach the cavities with a precision accuracy of ±.002″ on these 8.5” long by 1.75-4.00″ wide work pieces. Committed to quality, we conduct careful inspections to ensure that dimensional tolerances are met. We ship the finished parts to the customer along with all applicable quality documentation and certifications required by the military and firearms industry.
