AHS CNC 60/25-30 Plate Roll
The AHS CNC 60/25-30 is a heavy-duty CNC plate roll suited to cylindrical sheet and plate forming in general fabrication, where controlled rolling of thicker materials and repeatable production are priorities.
Quick Look
- Machine type: CNC 4-roll style plate roll (heavy-duty cylindrical sheet/plate forming)
- Typical use: Cylindrical shell rolling for tanks, pipes, structural components, and general fabrication
- Automation level: CNC-controlled movement of rolls for repeatable bends and multi-pass programs
- Application focus: Heavy-duty metal forming, production of consistent diameters and cones (when supported by machine configuration)
- Operator profile: Fabrication shops, job shops, and production environments handling thicker plate
Typical Cost Ranges
Pricing estimate (USD): $150,000 – $400,000 USD, depending on configuration, capacity, CNC package, and condition.
- Lower end of range: Older used units, basic CNC, fewer options, or lower roll capacity within the model family.
- Mid-range: Well-maintained used machines with standard CNC controls and typical heavy-duty options.
- Upper end of range: Late-model or fully equipped machines with advanced CNC, extended capacity, and additional automation.
- Additional costs: Installation, training, freight, electrical work, and any required foundations or pit work.
- Operating costs: Power consumption, hydraulic oil, routine wear items (bearings, seals, hydraulic hoses), and periodic CNC service.
Specs That Matter
- Plate thickness capacity: Match the machine’s rated maximum thickness (in the material grade you run most) to your heaviest jobs, including any pre-bending derating.
- Working length: Ensure the roll length covers your widest plate; consider a margin for handling tolerances and any edge trimming.
- Top roll diameter and roll geometry: Larger diameters and proper roll spacing help reduce flat ends and improve roundness on thicker plate.
- CNC control capability: Look at number of programmable axes, stored programs, step-by-step sequences, and ease of use for repeat jobs.
- Hydraulic system performance: Pump size, pressure capability, and cylinder sizing affect pre-bend power, repeatability, and cycle times.
- Frame rigidity and construction: Heavy welded or cast frames resist deflection under load, improving accuracy on heavy-duty work.
- Support equipment: Side and overhead supports, feeding tables, and cone-forming attachments (if applicable) improve handling and part quality.
What to Inspect Before You Buy
- Confirm actual plate capacity: Verify nameplate data and compare to your required thickness, width, and material grade (e.g., mild vs high-strength steel).
- Check roll surfaces: Inspect for scoring, flat spots, corrosion, or weld spatter that could mark finished cylinders.
- Evaluate roll alignment: Perform a visual and test-roll check for taper, uneven bending, or excessive flat ends across the full width.
- Assess hydraulic system: Look for leaks, listen for pump noise, and check that pressure builds and holds consistently under load.
- Test CNC functions: Run through a full program, verify axis feedback, position repeatability, and check for alarm histories or control faults.
- Inspect mechanical wear: Check bearings, bushings, guides, and adjustment mechanisms for play, backlash, or uneven wear.
- Review electrical cabinet: Look for clean wiring, intact labeling, and any signs of overheating, moisture, or non-original modifications.
- Verify safety systems: Confirm the operation of e-stops, safety bars, light curtains (if present), interlocks, and guards.
- Check documentation: Ensure availability of manuals, electrical and hydraulic schematics, CNC backups, and maintenance records.
- Confirm power and footprint: Match machine voltage and amperage to your plant supply and verify floor space, access, and handling clearances.
Buyer Questions
What materials can this type of plate roll handle? Typically suited for carbon steel, stainless steel, and similar metals within the machine’s rated thickness and width; always check capacity charts for different material strengths.
How do I know if the machine can pre-bend my plate in one pass? Compare your maximum plate thickness, width, and material grade to the machine’s specified pre-bending capacity, which is usually lower than its rolling capacity.
Is CNC necessary for general fabrication work? CNC is highly beneficial when you repeat diameters, run multiple passes, or need consistent results across batches; for one-off work, it still helps reduce trial-and-error and operator dependency.
What impact does roll diameter have on my parts? Larger top-roll diameters generally improve roundness on thicker plate and reduce the risk of plate wrinkling, but may limit very tight diameters on thin material.
Can this machine form cones as well as cylinders? Many 4-roll plate rolls can form cones if equipped and configured correctly; verify whether the specific machine has cone-forming capabilities and any required accessories.
How important is frame rigidity on a heavy-duty plate roll? Very important; a rigid frame reduces deflection under heavy loads, improving diameter consistency, edge quality, and long-term accuracy.
What should I look for in the CNC control interface? Check for clear graphics or prompts, straightforward program editing, storage capacity for jobs, and support for multi-pass sequences and different material libraries.
How can I evaluate a used machine’s condition without full disassembly? Inspect roll surfaces, check for leaks and unusual noises, run a test roll across full width, review alarm histories, and look over maintenance records.
What plant infrastructure is typically required? You will need adequate electrical supply, a suitable floor or foundation, material handling (cranes or forklifts), and sufficient clearance around the machine for loading and unloading.
How does this cost range compare to other heavy-duty fabrication equipment? The $150,000 – $400,000 range is typical for heavy-duty CNC plate rolls and is comparable to other major capital machines such as large press brakes or medium-to-large machining centers.
