High Peak Power (HPP) enables running a CW laser in pulsed mode with up to 2x increase in peak power in comparison with CW average power. High Peak Power provides advanced processing capabilities for faster piercing, increased output quality, repeatability and waste reduction. HPP increases overall processing speeds, repeatedly drills clean holes and delivers high quality cuts of intricate parts with fine features while reducing overall laser power requirements.
HPP also enhances drilling capabilities by allowing clean, controlled drilling in thicker materials. For cutting applications this means shorter lead-ins and denser part nesting, which reduces material cost and waste. Available exclusively from IPG, High Peak Power provides improved cutting and drilling quality and increased overall throughput, while saving material, time and operating costs.
Traditional, low peak piercing is slow to punch through thick metals and creates an opening that allows debris to make its way to the top. Material cannot be expelled from the bottom, which causes spatter and welds the debris to the top surface. The hole produced by the pierce can be inconsistent and imperfect.
High Peak Power punches through thick metals faster and creates a smaller opening, reducing the amount of debris that makes it way to the top. Establishment of a gas flow channel expels the melt from the bottom, which significantly reduces the amount of spatter. The resulting hole produces by the HPP pierce is clean and consistent.
The reduced heat input of HPP ensures consistency of finished parts with numerous holes and contours, which enables processing of painted and coated materials.
High quality piercing and cutting provided by HPP reduces cycle times by not reworking parts and reduces wasted materials.
With small, clean and consistent piercing, HPP creates shorter part lead-in. For example, traditional piercing creates lead-in greater than 5 mm, whereas HPP lead-ins are just 1 mm in 6 mm thick metals.
This dramatically reduces material waste up to 25%, reducing overall operating costs and decreasing the cost-per-part.
