Manufacturing of chambers
The specialists of Promtekhnologiya LLC approach the manufacture of chambers with no less attention. For this type of work, both CNC machines and universal lathes with a digital control system are used. Making an accurate chamber is almost an art, so the equipment for solving these problems was also redesigned in the company’s design bureau. The machines had special devices installed on both sides of the spindle, which made it possible to adjust the position of the barrel according to the runout. Thus, before the reamer touches the barrel, special indicators along the internal channel set the runout with an accuracy of no more than 0.0025 mm on both sides of the barrel. This allows you to achieve maximum coaxiality (the location of the axes on the same line) of the chamber and the barrel, which means making shooting accuracy even higher.
In addition, special pilot reamers and floating cartridges, a special polishing system for the chamber and bullet entry are used for these operations.
Most chambers can be made to CIP or SAAMI standards with a short or long bullet entry, as desired by the buyer.
Manufacturing of fullers and muzzle brakes
ORSIS barrels can have a matte finish or be polished. In addition, at the request of the customer, fillers can be cut on the trunk. Fullers are not only a design element, but also allow solving a number of functional problems, including lightening the barrel and increasing its cooling rate; a special technique is used in which accuracy is not compromised.
It is also possible to install muzzle brakes-compensators (DTC) on the barrels. The use of a compensator allows, by changing the direction and speed of movement of part of the powder gases, to reduce the recoil impulse and increase comfort when shooting.
