Accurl CNC Punching Machine

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!

Here’s a practical guide to troubleshooting 5 common CNC punching machine errors, including symptoms, causes, and actionable fixes to minimize downtime and ensure precision: 1. Misalignment or Off-Center Punching Symptoms:   - Holes/features not matching the programmed position.   - Uneven material deformation or burrs.     Causes:   - Worn tool holders or loose dies.   - Incorrectly calibrated machine axes.   - Sheet slippage due to improper clamping.     Fixes:   - Check tool alignment: Use a dial indicator to verify punch/die concentricity.   - Re-calibrate the machine: Perform axis calibration via the CNC control panel.   - Secure the material: Ensure clamps or vacuum systems hold the sheet firmly.     2. Tool Breakage or Premature Wear  Symptoms:   - Chipped or cracked punches.   - Inconsistent hole quality (e.g., ragged edges).     Causes:   - Excessive tonnage for the tool/material.   - Incorrect tool clearance or lubrication.   - Hardened/dirty material damaging the tool.     Fixes:   - Adjust tonnage: Match punch force to material thickness/type (e.g., 30 tons for 6mm steel).   - Lubricate tools: Apply anti-seize grease to punches and dies.   - Inspect material: Remove surface debris (rust, scale) before processing.   3. Material Feeding Errors Symptoms:   - Sheet not advancing correctly.   - Misaligned features across the sheet.   Causes:   - Worn feed rollers or servo motor issues.   - Incorrect program parameters (e.g., feed rate, step distance).   - Debris blocking the material path.   Fixes:   - Clean the feed system: Remove metal chips or dirt from rollers and guides.   - Replace worn rollers: Check for flat spots or uneven wear.   - Verify program settings: Ensure step distance matches the sheet’s actual dimensions.     4. CNC Control/Software Glitches  Symptoms:   - Machine stops mid-program.   - Incorrect tool selection or erratic movements.     Causes:   - Corrupted program files or outdated firmware.   - Electrical interference or faulty wiring.     Fixes:   - Reboot the CNC controller: Power-cycle the system to reset errors.   - Re-upload the program: Transfer the file again to eliminate corruption.   - Check wiring connections: Inspect cables for loose terminals or damage.     5. Excessive Noise or Vibration  Symptoms:   - Loud knocking or grinding sounds during operation.   Visible machine shaking. If you have more ideas, please contact us!

Accurl  Cnc Turret Punching Machine, also known as a CNC punch press or simply a turret punch press, is a machine used for sheet metal processing. It is designed to punch holes, shapes and patterns in flat metal using a variety of punches and dies mounted in a rotating turret. The machine is controlled by a computerized numerical control (CNC) system that allows for precise and automated punching operations. The CNC Turret Punching Machine can be programmed to punch holes of different sizes, shapes and patterns in a variety of materials, including steel, aluminum and stainless steel. The turret on the machine accommodates multiple work stations, each containing a punch and corresponding die. The turret rotates to position the punch and die combination required for each stamping operation, providing quick and efficient tool changes. CNC turret punch presses offer several advantages, including high productivity, accuracy, versatility, and the ability to produce complex shapes and hole patterns. They are commonly used in the automotive, aerospace, electronics and metal fabrication industries for applications such as electrical enclosures, chassis, brackets and panels. The CNC punch and laser combined machine not only has servo punching processing technology, but also has the characteristics of high laser cutting efficiency and good cutting quality, which can realize punching holes, forming, laser cutting and other functions, and provide a new intelligent manufacturing solution for your production.
