Stainless Steel

Main frame, which is the body of AK380 SS, consisting of only one part goes through several production procedures.

In process 1, a hole is made to stainless steel raw material which has been cut according to AK380’s shape. The purpose of this hole is to prevent staggering of the raw material during processing.

In process 2, after fixing the hole that was made in process 1, the front side of the AK380 is processed. At this time, the side that is going through the 5-axis processing machine along with the front and the sides passes through the 4-sided processing procedure.

In process 3, the part processed in process 2 is turned over and fixed. Afterwards, the process of peeling and cleaning of inner sides takes place.

In process 4, the process of applying hairline patterns to the completed frame is carried out.

In process 5, when stainless steel has gone through all processes, exterior coating process takes place.
