Maximizing Your Laser’s Productivity

synchronization of the oscillator, CNC control and motion system. Using this flash-cutting technique, we start with a pierce directly on the line (with cutter compensation, of course), eliminating a lead-in. The beam cuts all of the lines of the grid pattern in one direction, and then cuts all of the lines running 90
deg. to the initial cuts. Operating at high speed, the laser beam begins pre- cisely at the corner of the square or rectangle, and then shuts off precisely at the opposite corner. As the cutting head continues toward the next rec- tangle, the beam again turns on pre- cisely as it reaches the coordinates for
that next corner. The process repeats back and forth until all of the parallel lines in one direction have been cut, and then the laser repeats that process to make the perpendicular set of cuts.
Flash cutting proves ideal for pro- cessing thin materials where no pierce routine is required. Machines equipped
In 1964, LSP introduced the original PresSpray, introducing airless, automatic spraying of die lubricants. Today, presses are faster and more high tech, tolerances are tighter, and lubricants better. The PresSpray-II has evolved to meet the demands of twenty first century stamping.
If you’re tired of trying to make one stamping lubrication design fit for all your jobs, talk to LSP. We offer a wider range of lubication solutions than any other manufacturer. Learn more about PresSpray and other technologies at
