Frequently Asked Questions

What is the primary purpose of CNC machining in firearm frame production?

CNC machining precisely cuts metal to form firearm frames and receivers. It ensures all dimensions are within specifications for proper fit and function, including critical internal rails for slide movement.

How is a tight slide-to-frame fit refined after initial machining?

A tight fit is refined through manual abrasion of slide rails, application of lapping compound, and repeated cycling of the slide on the frame. Minute adjustments may also be made with the CNC machine.

What is lapping compound used for in firearm assembly?

Lapping compound is an abrasive substance applied to mating surfaces like slide and frame rails. Repeated cycling with the compound creates a precise, smooth fit by gradually wearing down high spots and ensuring even contact.

What tools are essential for slide-to-frame fitting and lapping?

Essential tools include a CNC milling machine for initial cuts, gauges for dimension checks, sanding blocks or stones for rail abrasion, lapping compound, and a specialized rod tool for cycling the slide on the frame.
