Machine to manufacture gun barrels and method of using

A method of reaming a bore in a gun barrel comprising:

• providing at least one station comprising:
• a support block slidably connected to a track;
• a holder connected to the support block and adapted to hold a gun barrel;
• a reamer adapted to pass through the bore in the gun barrel when the gun barrel is held in the holder;
• a reamer drive for rotating the reamer about a longitudinal axis;
• a position drive mechanically coupled to the support block for moving the support block along the track;
• and
• a controller for controlling the reamer drive and the position drive;
• providing gun barrel having a bore,
• securing the gun barrel to the holder such that the longitudinal axis of the reamer is co-axial with a longitudinal axis of the bore of the gun barrel, and
• sending a signal from the controller to power the reamer drive and the position drive such that the reamer drive causes the reamer to rotate at a constant speed and the position drive causes the support block to move along the track at a constant speed when the reamer is in contact with the gun barrel,
• wherein the reamer drive and the position drive are separate drives, and wherein the reamer drive rotates the reamer at a constant speed and the position drive simultaneously moves the support block at a constant speed along the track causing the rotating reamer to be received in and pass through at least a portion of the bore of the gun barrel so as to move the reamer through the bored body and ream the bored gun barrel.
