Arclight Dynamics Arc Max Ultra 4x8

A 4 x 8 plate sits inside the 50 x 97 in cutting envelope of the Arclight Dynamics Arc Max Ultra 4x8 with about an inch of margin each way, and Z is 6.5 in. It is the heavy-frame Arc Max table running Arclight CNC software. This is the full-sheet size for shops whose plate arrives as 4 x 8 stock.

Weight is deliberate here. A fully welded, unitized frame of 3 x 3 in tubing with a 3/16 in wall carries a light aluminum gantry on Hiwin 20 mm linear guide rails, driven on both sides. Gantry clearance is 8.5 in. Arclight rates the table for 2 in mild steel and lists 0.001 in positioning accuracy. Plate slides on over rollers built into the frame, level with the slats, and the table ships fully assembled.

The table weighs 2,500 lb empty and its water pan takes 250 gallons, so it is not something to reposition casually. Base dimensions are 58 x 109 in; overall dimensions are listed as 120 in L x 76 in W x 60 in H. With only an inch or so of spare envelope, plate has to be squared carefully or corrected in the control.

Arclight CNC software, written for this series, runs on industrial Linux and communicates over Ethernet. It gives rewind and fast forward along the cut path, start point recovery after a power-down, plate skew correction and an auto rip cut for remnants. Torch height control and dynamic voltage sampling are standard. Under the slats, the water pan is 8 1/2 in deep in 12g steel with an expanded metal barrier that catches small parts, and it drains through twin 1.25 in ball valves. The plasma cutter is chosen separately.
