Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
The corporation claims to have a system ready for testing as a potential long-range naval fire support weapon for emerging ships, such as the Zumwalt-class destroyer. The CLGG, like the railgun, is a possible candidate technology for greater ranges for naval systems, among others. UTRON has built and tested 45mm and 155mm combustion light-gas guns.
Thin-wall milling of aluminum using a water-based cutting fluid on the milling cutter. Cutting fluid is a type of coolant and lubricant designed specifically for metalworking processes, such as machining and stamping. There are various kinds of cutting fluids, which include oils, oil-water emulsions, pastes, gels, aerosols (mists), and air or ...
The light-gas guns are typically divided into categories of single-stage and two-stage light gas gun. [1] One such single-stage light gas gun is located at Marquette University, Milwaukee, WI. It had been used for studying polymers and metals in pressure regions up to 20 GPa. The light gas gun at Marquette was manufactured by PAI and delivered ...
At high temperature, these flammable gasses will ignite when turbulently mixed with atmospheric oxygen beyond the muzzle of the gun. During night engagements, the flash produced by ignition can reveal the location of the gun to enemy forces [7]: 322–323 and cause temporary night-blindness among the gun crew by photo-bleaching visual purple.

A valve job is the colloquial term for resurfacing the mating surfaces of the poppet valves and their respective valve seats that control the intake and exhaust of the air/fuel mixture in four stroke internal combustion engine, replacing valve oil seals, replacing any deficient valve springs, and otherwise bringing the components of a cylinder head up to manufacturer’s spec. [1] A ...

Diagram of long-stroke gas operation system Long stroke gas piston, from an AK-74. With a long-stroke system, the piston is mechanically fixed to the bolt group and moves through the entire operating cycle. This system is used in weapons such as the Bren light machine gun, AK-47, Tavor, FN Minimi, FN MAG, FN FNC, and M1 Garand.
