Brass bar loading machine will load out the 3-meters long brass bar to the forming machine. This is an index type machine. The bar will be hold tight and cut it into pieces. The pieces will be sent for fine milling the surface to get the exact length. Then each station will drill 2 pinholes on the barrel for getting total 6 pinholes on one barrel. The other drilling stations will also drill the barrel retainer pin hole and the easily-inserting hole. Hollow cutting on the bottom end of the barrel and end-milling the bottom end into plate are also available in this machine. Arc milling on the barrel, de-burring for the edge of the pinholes and chamfering on the top end of the barrels are all at the selection list. When all the processes are done, the finished barrels will be kicked out to the slide.
