Condition: new, Year of construction: 2025, All-round sheet fiber laser metal cutting machine Equipped with automatic functions of nozzle changing and one-click processing, P-Series is competent for all cutting demands. Flake graphite in the cutting machine bed improves greatly the shock absorption and wear resistance, and residual stress almost disappears after age hardening, therefore, precision and lifetime of the equipment are improved, and costs saved. The special fiber laser nozzle and cutting process ensure faster carbon steel oxygen cutting, more gas-saving low-pressure stainless steel nitrogen cutting, and better-quality carbon steel air cutting. Fiber laser heads are able to detect jutting obstacles to effectively reduce the damage rate and save the maintenance cost of a laser cutter. The fully closed-loop control adjusts according to feedback to ensure that the actual motion position is consistent with the theoretical input value. Dedpfx Aohwhfisa Nekl With One-click Processing, one laser cutter is able to process multiple sheets in batches with a one-off setup, achieving batch processing.

Condition: new, Year of construction: 2025, BAYKAL Plasma Cutting Machine Systems, BPL H: Highly accurate and reliable performance with positioning speeds. Key Advantages of BAYKAL Plasma Cutting Machine Systems; BAYKAL Plasma cutting is comparatively cheap for medium thickness cuts. High-quality cutting for thicknesses up to fifty millimeters. Dsdpsr En Risfx Aa Nskl Maximum thickness of one hundred and fifty millimeters. Plasma cutting can be carried out on all conductive materials, in contrast to flame cutting which is only suitable for ferrous metals. When compared to flame cutting, plasma cutting has a significantly smaller cutting kerf. Plasma cutting is the most effective means of cutting medium thickness stainless steel and aluminum. Faster cutting speed than oxyfuel. CNC plasma cutting machines can offer excellent precision and repeatability. Plasma cutting can be carried out in the water which results in smaller heat-affected zones as well as minimizing noise levels. Plasma cutting can cut more complex shapes as it has high levels of accuracy. Plasma cutting results in minimal dross as the process itself gets rid of excess material, meaning very little finishing is required. Plasma cutting does not lead to warping as the fast speed significantly reduces the heat transfer.
