The CNC Punch Laser Combined Machine represents a breakthrough in modern sheet metal processing, integrating the high-speed precision of CNC punching with the flexibility and cutting quality of laser technology. This hybrid solution allows manufacturers to perform punching, forming, and complex laser cutting in a single setup, significantly improving productivity and reducing material handling time. With advanced automation, intelligent control systems, and versatile processing capabilities, it delivers exceptional efficiency, accuracy, and cost-effectiveness for a wide range of industrial applications. In this blog, we will explore the key technical highlights that make this combined machine a game-changer in the sheet metal industry.   1. Efficient collaborative processing (seamless switching between stamping and laser) Automatic switching technology Through the automatic switching of the turret mold library (such as 16 stations) and the laser cutting head, continuous processing of "punching → cutting → forming" is achieved without the need for secondary clamping. Time-saving: For instance, when processing the panels of electrical cabinets, after stamping the ventilation holes, the contour is directly laser-cut, which increases efficiency by 30% to 50%. Composite process path optimization CAM software (such as TruTops Boost) automatically plans the optimal processing sequence to avoid repetitive positioning errors.   2. Ultra-high precision (within ±0.1mm) Laser compensation for stamping error Stamping may cause material deformation or burrs, while laser cutting can precisely trim the edges (such as removing stamping burrs). Dynamic focus control The laser head is equipped with Z-axis auto-focusing, adapting to materials of different thicknesses (0.5 to 20mm). High-rigidity machine tool structure The cast iron bed and linear guide rails are adopted to reduce vibration and ensure the positioning consistency of laser cutting and stamping.   3. Multi-functional integration (One machine can complete multiple processes Stamping function Supports punching, tapping, embossing, blind forming, etc. Laser function Fiber lasers (1 to 6kW) can cut carbon steel, stainless steel, aluminum and copper, and can also perform precise engraving. Special process expansion Some models support the integration of bending units, achieving a three-in-one combination of stamping, laser and bending.   4. Intelligence and automation Intelligent material arrangement system AI algorithms optimize the utilization rate of sheet materials (such as automatically nesting punching and cutting paths to reduce waste). Internet of Things (IoT) remote monitoring Real-time monitoring of mold life, laser status, and energy consumption data, predictive maintenance reduces downtime. Automatic loading and unloading options Combined with robots or material warehouses, it can achieve 24-hour unmanned production.   5. Energy-saving and environmentally friendly design Hybrid power stamping Servo motor-driven stamping saves 40% energy compared to traditional hydraulic presses. Laser sleep mode It automatically reduces power consumption when in standby mode. Dust removal system Integrated pulse dust removal reduces the pollution of laser cutting smoke and dust.   If you have more ideas, please contact us!

The processing capacity of a CNC punching machine is influenced by multiple factors such as material type, machine tool model, mold design and process parameters. The following is the thickness range and key points of CNC punching machine processing sorted out after comprehensive search results: 1.The conventional processing thickness of a common CNC punching machine - Low-carbon steel: Usually 0.8 to 3.5mm, with a recommended thickness of less than 3.5mm; If special processes (such as roof cutting or concave cutting design) are adopted, it can be processed to 6mm. Stainless steel: The recommended thickness is 0.8 to 2.5mm. However, due to the rapid tool wear and high scrap rate, CNC punching machines are generally not preferred for processing. - Aluminum/copper plates: The recommended thickness is 0.8 to 4.0mm. However, it should be noted that soft materials are prone to sticking to the mold, so coating punches should be used or the mold gap should be adjusted.   2. The processing capacity of the special CNC punching machine for thick plates Carbon steel plate: Some dedicated models for thick plates (such as the NCPH series) can process up to 16mm in thickness and have a nominal stamping force of 3150KN, making them suitable for processing thick plates such as automotive longitudinal beams. - Other materials: such as copper, aluminum and other soft metals. By optimizing the mold gap (increasing by 5% to 20%) and tonnage calculation, it can be processed to 12.7mm (such as 1/2 inch).   3. Key factors affecting processing thickness Tonnage requirement: For punching thick materials, a higher tonnage is needed. The calculation formula is: land inches × material thickness × shear factor ×25. For example, a hole with a diameter of 2 inches and a thickness of 6.35mm requires more than 39 tons of force, which exceeds the capacity of ordinary machine tools. - Mold design: - Mold clearance: For thick materials, the mold clearance should be increased (for example, for low-carbon steel, it should be adjusted from 15% to 20%) to reduce demolding issues. - Punch material: Powder metallurgy punches are recommended to enhance impact resistance, and a coating is added to reduce the risk of soft materials adhering to the mold. - Maintenance and processing: Blunt tools will increase the required tonnage and need frequent grinding to extend their service life; Shearing designs (such as roof shears) can reduce tonnage requirements.   4. Special models and process expansion - Fully automatic CNC punching machines (such as DHSKC-Q series) : The maximum processing thickness is 6mm, supporting complex shapes such as round holes and special-shaped holes, suitable for industries like electronics and medical devices. - Turret punch press (such as COMA-567) : Optimized for thin plates, suitable for carbon steel plates under 2mm, with limited processing capacity for thick plates. Laser cutting alternatives: For ultra-thick materials (such as ≥16mm) or high-precision requirements, laser cutting is superior, but it is more costly and not suitable for materials with fast heat conduction, such as aluminum and copper.   5. Practical application suggestions - Material selection: Prioritize materials such as low-carbon steel and aluminum plates that are easy to machine. For stainless steel, carefully assess the cost of the cutting tools. - Equipment selection: For thick plate processing, dedicated models (such as the 16mm thick plate CNC punching machine from Qingdao Kelida) should be selected, and they should be equipped with high-precision servo systems and ball screws. - Process optimization: Use multi-station molds and automatic programming software (such as CAD to directly generate codes) to enhance efficiency. At the same time, pay attention to the design of hole spacing to avoid mold strength issues.   Summary Ordinary CNC punching machines are suitable for low-carbon steel plates of 3.5mm or less or aluminum/copper plates of 4mm or less. The special model for thick plates can be extended to 16mm carbon steel. The actual processing should be combined with the material properties, equipment capabilities and process adjustments. When necessary, laser cutting or cold stamping dies can be used as supplementary processing. If you have more ideas, please contact us!
