Here, the laser head need not pause when transitioning between piercing and cut- ting. It’s one smooth process that can yield as much as a 30-percent cycle-time reduction compared to traditional piercing. For thicker sheet, fabricators will opt for the Max Cut pierce mode, featuring a hefty flow of nitrogen delivered to the workpiece material. This cooling effect reduces what can be a pierce time of 3-4 sec. down to less than 1 sec. And, for unattended cutting, Prima offers the Night Cut piercing mode, featuring a wide parameter window to ensure reliable and safe

Roller Lubrication
The MiniCoater line of roller coaters places lubricant on coil stock before it enters the die. Computer control allows the MiniCoater to dispense the correct amount of lubricant on each cycle of the press. Individual manifolds can be

Solid-State Cutting with 8-kW Engine
www.primapower.com.en
Trumpf debuted its 8-kW TruDisk laser, driving its TruLaser 5030 cutting machine, designed to significantly boost productivity when cutting medium to thick sheetmetal. The TruLaser 5030 fiber was shown equipped with Trumpf’s CoolLine, BrightLine and enhanced Pierce- Line functions, to support processing thicker materials. During cutting, the CoolLine nozzle directs a water mist around the laser beam as it reaches the workpiece. This reduces the heat transferred in the immediate cut- ting zone and achieves contours—small sidewalls and difficult geometries—that would otherwise be difficult or impossible to process. BrightLine nozzle technol- ogy accelerates the cutting gas to a high velocity and features special cutting data to allow fab- ricators to laser-cut stainless steel as thick as 0.8 in. And, the new PierceLine function regulates the piercing process to provide just the right amount of laser power for as short a time as needed, so that average power always stays just below the limit at which the material would burn off uncontrol- lably. The result, say company officials, is precisely pierced holes with a minimum amount of ejected material. www.trumpf.com/en
Select from Three Cutting Modes, Balancing Quality, Cost and Speed
Murata Machinery introduced its LS3015FC fiber-laser cutting machine, which allows users to select among three cutting modes: high quality, for the best pos- sible cut; economy, which reduces gas consumption and operational costs; and
high-speed, for the fastest production time. The machine features lin- ear drives on all axes for precise, high- speed processing. A dual-pallet sys- tem preps new material and eliminates parts and scrap from falling onto the material during
exchange.
The Muratec MVHS
proprietary control sys-
tem adjusts to changes in the laser’s output with- in milliseconds. Included
is a light-monitoring sys- tem that helps to prevent reflected light from damaging the laser, and continuous monitoring of processing parameters outside of the normal range. When detecting abnormal cutting parameters, the machine will stop pro- cessing to avoid damage or wasted material. www.fiberlasermachines.com MF
