Processing Cell Can Drill, Ream and Rifle 20,000 Firearm Barrels in Month
Absolute Machine Tools' offering of machine tools and automation systems includes machines specifically engineered for drilling, reaming and rifling of small-caliber gun barrels. Sold under the Precihole brand name, the machines can be combined into processing cells that enable a manufacturer to efficiently drill, ream, and rifle as many as 20,000 small-caliber firearm barrels a month.
A cell is typically composed of three machines. First, Precihole's four-spindle gun drilling machine permits deep drilling of four barrels simultaneously. An open machine configuration facilitates robot access, minimizing operator involvement and supporting 24/7 operation. Depending on individual model configuration, the machine can drill IDs from 0.04" to 1.57" and barrel stock from 0.4" -- 4.0" OD.
Next in the process is a 2-spindle pull-reaming machine that features automation for insertion and repositioning of reamers. Reduced setup time and rapid operating parameters (0-20 IPM pulling speeds) support high-volume barrel finishing and polishing. Different machine configurations handle reaming diameters from 0.15" to 0.59" and depths from 24" -- 60".
Finally, Precihole's button rifling machine forms precise barrel grooves at speeds up to 80 IPM. Depending the machine model, rifling size can range from 0.15" -- 0.59", and depth from 24" -- 60".
"Our company's offering of small-caliber barrel machining and automation equipment can enable firearm manufacturers to optimize their operations and reduce the cost of the guns they produce," said Courtney Ortner, Absolute Machine Tools Director of Marketing and A+ Automation Team.
