Technical overview
Max cutting thickness (rating): up to 3/8" mild steel (≈ 10 mm)
Supports a wide range of plate jobs in mild steel. Rating is defined for mild steel; stainless and high-strength steels require reduced thickness and/or cut length. For near-limit use cases, tensile strength and duty cycle must be reviewed with ANCHU.
Max cutting length: 10' (≈ 3200 mm)
Enables full-length shearing of standard plates, reducing the need for multiple setups or trimming passes on long parts, and supporting efficient blanking for large weldments and frames.
Backgauge: Motorized, digital/NC, typical stroke 24–40" (example)
NC-controlled backgauge for programmable cut lengths and batch quantities. Typical travel covers most common blank sizes; exact stroke, accuracy, and repeatability depend on the ANCHU backgauge configuration supplied with the machine.
Shear type: Hydraulic guillotine
Hydraulically driven upper blade beam traveling in a near-vertical path. Guillotine geometry maintains consistent rake angle and blade clearance along the full cutting width, supporting uniform cut conditions and edge quality.
Frame & construction: Heavy welded steel frame
Rigid welded structure designed to minimize deflection under the forces required to shear 3/8" plate at 10' length, supporting consistent squareness and straightness across the life of the machine.
Hold-downs: Hydraulic, distributed along cutting line
Multiple hydraulic hold-down cylinders clamp the material before cutting, preventing lift and slip. Proper hold-down pressure is key to safe operation and consistent part length/edge quality on heavier plate.
Power: 480 V three-phase (other voltages available)
Standard US industrial power configuration. Alternative voltages/frequencies and ANCHU PowerPhase solutions are available to adapt the machine to site power constraints, subject to power and duty analysis.
Safety: Front/side guards, safety interlocks, emergency stop circuits
Integrated guarding and safety circuits support compliance with common industrial safety expectations. Final compliance depends on site-specific risk assessment, guarding layout, and operating procedures.
Extended specification details
The values below represent typical ranges for a 3/8" × 10' hydraulic guillotine shear in this class. Replace “example” values with exact certified ANCHU specifications before publishing.
Strokes per minute (example at full stroke): ≈ 8–12 spm
Representative cutting rate at maximum stroke length on heavier material. For thinner sheets and reduced stroke settings, higher stroke rates may be achievable. Actual values depend on hydraulic sizing and NC control parameters.
Rake angle (example): ≈ 1–3°
Rake angle influences cutting force, twist, and edge quality. Lower angles improve squareness and reduce twist, but increase force; higher angles reduce force at the cost of potentially more twist on narrow strips. Guillotine geometry keeps the effective rake well-controlled along the length.
Blade clearance adjustment: manual or motorized (per configuration)
Blade clearance must be tuned to thickness and material. Undersized clearance raises cutting force, accelerates blade wear, and can tear edges; oversized clearance increases burr and roll-over. Operators adjust clearance using ANCHU’s recommendations for each material/thickness combination.
Hold-down system: multiple hydraulic cylinders across 10' (example)
Distributed hold-downs maintain plate flatness and prevent slip during cutting. The exact number, spacing, and clamping force range are specified in the ANCHU mechanical drawings and spec sheet for this model and configuration.
Front squaring arm length (example): ≈ 39–60"
Squaring arm with scale and stops for accurate 90° alignment of the leading edge. Arm length and features (T-slots, flip-up stops) depend on chosen options and configuration level.
Support arms: front support arms with stops
Support arms help carry large or thin sheets, reducing sag and improving cut straightness and operator ergonomics. Stops or fingers provide repeatable front-edge positioning for recurring jobs.
Main motor power (example): ≈ 20–40 hp (15–30 kW)
Typical installed motor power for a 3/8" × 10' hydraulic guillotine shear. Exact horsepower depends on required stroke rate, pump selection, and expected duty cycle at or near maximum thickness and length.
Hydraulic system: conventional hydraulic power unit
Hydraulic power pack with pump, valves, tank, filtration, and (optionally) cooling. Oil volume, cooling capacity, and filtration must match the anticipated duty cycle and ambient conditions in the shop environment.
Backgauge travel (example): ≈ 24–40" (600–1000 mm)
Defines maximum programmable distance from the blades. Longer travel expands nesting options and supports larger blank sizes. Confirm exact travel range and minimum distance in the ANCHU model-specific spec sheet.
Backgauge accuracy (example): up to ±0.004" (±0.1 mm)
Representative backgauge repeatability and positioning accuracy under proper installation and calibration. Guaranteed values depend on the specific backgauge hardware and NC control supplied with the machine.
Table height (example): ≈ 30–33" (760–840 mm)
Height from floor to table surface, affecting operator ergonomics and compatibility with infeed/outfeed tables, roller conveyors, and material handling equipment.
Machine weight (example): ≈ 20,000–35,000 lb
Typical weight range for a heavy-duty 3/8" × 10' guillotine shear. Floor loading, anchoring, and handling requirements must be checked against the machine drawing and facility structural data.
Important: All “example” values above are indicative and not guaranteed for every configuration. Use the official ANCHU quotation, certified spec sheet, and installation drawing for engineering and safety decisions.
Cutting performance & material guidelines
The 3/8" × 10' rating is defined for mild steel at a specified tensile strength and duty cycle. Actual capability depends on thickness, material strength, cut length, rake angle, blade condition, and how often you operate near maximum capacity.
Conceptual shear force relationship:
F = τ × t × L
- F – required shear force
- τ – shear strength of the material
- t – material thickness
- L – length of cut
For many steels, shear strength is roughly ~0.6 × tensile strength (Rm). Engineers should use actual material data and apply a safety factor, especially when shearing heavier plate at full 10' length or running sustained high-duty schedules.
Illustrative material guidelines
| Material | Relative to 3/8" rating | Typical recommendation* |
|---|---|---|
| Mild steel (baseline) | Reference case | Up to 3/8" at full 10' per rating, subject to tensile strength, duty cycle, and appropriate settings for rake angle, clearance, and hold-down pressure. |
| Stainless steel | Higher strength than mild | Reduce allowable thickness and/or cut length; borderline applications should be confirmed with ANCHU engineering using actual material properties. |
| High-strength low-alloy (HSLA) | Significantly higher strength | Consider thinner material, shorter cuts, or a higher-capacity shear for heavy or continuous workloads. |
| Aluminum | Lower strength | 3/8" is usually conservative in terms of force; focus on blade clearance, support, and handling to control burr and edge deformation. |
*Guidelines only. Actual limits must be checked against ANCHU capacity charts, the specific material datasheets, and your planned duty cycle.
What this means in practice
- The machine targets heavier mild steel plate up to 3/8" at full 10' length and thinner materials at higher throughput.
- When working near the rating, thickness, cut length, and material strength must all be considered together.
- Correct tuning of rake angle, blade clearance, and hold-down pressure is essential for acceptable edge quality, twist control, and blade life.
- For continuous near-limit operation or aggressive material mixes, consider maintenance strategy and whether higher-capacity equipment might be appropriate.
Mechanical design & cutting geometry
The ANCHU Shear 3/8" × 10' US uses a hydraulic guillotine architecture with a rigid welded frame and controlled cutting geometry to deliver straight, repeatable cuts on heavier plate.
- Welded monolithic frame: Engineered to absorb and distribute cutting loads with minimal deflection, supporting cut squareness and straightness across the full 10' width.
- Guillotine blade motion: Upper blade beam travels in a near-vertical path guided by robust slideways, maintaining consistent rake angle and clearance along the cut length.
- Rake angle behavior: The guillotine design sets an effective rake angle that balances cutting force, twist, and edge quality for the target thickness and material range.
- Blade clearance adjustment: Adjustable clearance allows operators to tune for each material and thickness, balancing burr height, roll-over, and blade wear.
- Hydraulic hold-downs: Clamp the plate securely before the cut, preventing lifting or creep and improving both safety and dimensional consistency, especially on heavier plate.

Engineering notes & technical FAQ
This section addresses typical questions from engineers and technical buyers: how to interpret the 3/8" × 10' rating, what drives cut quality, and what information is required for a proper engineering review.
How should I interpret the 3/8" mild steel rating at 10'?
The rating is defined for mild steel of a specified tensile strength at full 10' cutting length and for a given duty cycle. In practice:
- Higher-strength materials require more force, which may require derating thickness and/or cut length.
- Continuous cutting at maximum thickness and length increases stress on hydraulic and mechanical systems.
- Duty cycle (how often you cut near the limit) is as important as the peak capacity value itself.
What role do rake angle and blade clearance play in cut quality?
Rake angle and blade clearance are primary tuning parameters affecting cut quality, twist, and machine loading:
- Lower rake → better squareness and less twist, but higher cutting force and stress on the system.
- Higher rake → lower force, but potentially more twist on narrow strips and small blanks.
- Correct blade clearance → minimized burr, controlled deformation, and longer blade life.
- Incorrect clearance → too tight causes excessive wear and tearing; too loose increases burr and roll-over.
What backgauge accuracy and cut tolerances are realistic?
Real-world tolerances combine machine capability with material behavior and handling:
- Backgauge repeatability is typically within a few thousandths of an inch in this class under proper setup.
- Plate camber, residual stress, and operator technique affect final length and squareness of parts.
- Very tight dimensional or edge requirements may still need secondary processes such as machining or grinding.
How can I confirm my materials are within safe working limits?
To validate an application, compare required shear force and duty cycle against the machine’s rating:
- Use actual shear or tensile strength from material datasheets, not generic assumptions.
- Account for maximum thickness tolerance and potential variation in material strength.
- For stainless, HSLA, and other high-strength alloys near the limit, consult ANCHU engineering.
What information does ANCHU need for an engineering review?
To give a clear yes/no answer and recommend machine settings, ANCHU typically requests:
- Material type(s), grade(s), thickness range, and mechanical properties (if available).
- Sheet/plate sizes and sample cut patterns or part drawings/DXF files.
- Required tolerances for length, squareness, and edge quality, including downstream process needs.
- Expected production volumes and duty cycle (cuts per hour, shifts per day, mix of thicknesses).
- Any special requirements (e.g., stainless focus, HSLA focus, or integration into automated lines).
With this information, ANCHU can confirm whether the 3/8" × 10' hydraulic guillotine shear is appropriate for your workload or whether a different capacity or configuration is recommended.
