JMT ADM Series Structural Drill Lines
Available with 1, 2, or 3 individual spindles, our structural drill lines are best suited for construction involving steel, bridges, or shipyards. With the ability to drill H, I, and U configurations as well as angle iron with diameters of .4” up to 1.5” and more, these can make drilling much more efficient. Each spindle is independently programmed with its own X, Y, and Z axis, so each spindle can work on the same beam simultaneously. A CNC control resets to zero after each position before moving the spindles to the next position, so drills are exact and precise.
Each machine has linear guides, central lubrication, and a tool cooling system to ensure smooth operation and lower maintenance. Within each coordinate system there is a 4 station tool changer, allowing it to drill, mill, scribe, counter sink, or tap as needed; tools can even be swapped out mid-operation easily and without disruption. Positive beam positioning consists of an arm attached to a rack and pinion system on the feed conveyor to more accurately position the beam as it goes through the drill line, maintaining .004”, much more accurate than friction rollers are.
JMT 3ADM Series Structural Drill Line
JMT’s AKDRILL ADM Drilling Machines provide high quality solutions in manufacturing of steel construction, bridge construction, shipyards and various other fields of construction. ADM series have the drilling capacity of H, I, and U profiles or angle iron with standard diameters of .4″ to 1.5″ or more.
ADM Drilling Lines consist of one, two or three independent spindles.
The 1ADM series have a single spindle and the capacity of drilling the profile from three sides with right angle and by rotating +90 / -90 degrees.
The 3ADM series have three spindles and the capacity of independently drilling the profile from three sides, branding and tool changing at the same time. Resetting the equipment to zero and setting to the next drilling position are done automatically by the CNC control.
