Technical overview
Max cutting thickness (rating): 1/4" mild steel (≈ 6 mm)
Handles typical sheet and light plate jobs. Rating is defined for mild steel; capacity must be reduced for stainless or high-strength materials. For borderline cases, evaluate thickness and tensile strength together.
Max cutting length: 10' (≈ 3200 mm)
Suitable for full-size sheets, panels, and structural blanks. Shorter parts can be nested across the width to improve material utilization, subject to hold-down spacing and scrap constraints.
Backgauge: Motorized, digital/NC, 24–40" stroke (typical)
Programmable backgauge travel supports repeatable part lengths and batch runs. Exact travel, accuracy, and repeatability depend on the final ANCHU backgauge configuration.
Shear type: Hydraulic guillotine
Hydraulically driven upper blade beam in a near-vertical path. Guillotine geometry helps maintain consistent rake angle and blade clearance, improving cut quality along the full length.
Frame: Heavy welded steel construction
High-rigidity welded frame designed to minimize deflection under cutting loads. Frame stiffness is critical for maintaining squareness, straightness, and long-term accuracy in production duty cycles.
Hold-downs: Hydraulic, along the cutting line
Multiple hydraulic hold-down cylinders clamp the sheet before blade engagement. Proper clamping reduces plate lift and slip, resulting in cleaner, safer cuts and consistent dimensions.
Power: 480V 3-phase (other voltages on request)
Standard configuration for North American industrial plants. Alternative voltages and frequencies can be supplied; phase conversion options available for 240V single-phase sites via ANCHU PowerPhase.
Safety: Foot pedal with E-stop, front/side guards, safety interlocks
Integrated safety functions support compliance with common industrial safety practices. Final compliance depends on site-specific risk assessment and guarding layout.
Extended specification details
The values below represent typical ranges for a 1/4" × 10' hydraulic guillotine shear in this class. Replace “example” ranges with exact certified ANCHU values before publishing.
Strokes per minute (example at full stroke): ≈ 10–18 spm
Typical cutting rate at maximum stroke length. For thin materials with reduced stroke, higher stroke rates may be achievable. Actual values depend on hydraulic design and controller settings.
Rake angle (example): ≈ 1–3° (fixed or adjustable)
Rake angle influences cutting force, strip twist, and edge quality. Lower rake improves squareness but increases required force; higher rake reduces force but can increase twist on narrow strips.
Blade clearance adjustment: manual or motorized (per configuration)
Blade gap must be set appropriately for each thickness and material type. Undersized clearance increases wear and can tear the edge; oversized clearance increases burr and roll-over.
Number of hold-downs (example): distributed cylinders along 10'
Multiple clamping points maintain plate flatness and prevent sliding during cutting. Actual count, spacing, and pressure range are defined in the ANCHU mechanical drawing and spec sheet.
Front squaring arm length (example): ≈ 39–60"
Squaring arm with scale and stops helps align the leading edge of the sheet for accurate 90° cuts. Length and feature set (T-slots, flip-up stops) depend on the configuration and options selected.
Support arms: front support arms with stops
Support arms carry large or thin sheets, reducing sag and improving cut straightness. Typically include mechanical stops or fingers for repeat part positioning.
Main motor power (example): ≈ 10–20 hp (7.5–15 kW)
Typical installed motor power for a 1/4" × 10' hydraulic shear. Exact horsepower depends on required stroke rate, hydraulic pump selection, and duty cycle expectations.
Hydraulic system: conventional hydraulic power unit
Power pack with pump, valves, tank, filtration, and (optionally) cooling. Sizing and cooling capacity must match the planned production duty cycle and ambient conditions in the shop.
Backgauge travel (example): ≈ 24–40" (600–1000 mm)
Defines maximum programmable cut depth from the knives. Longer travel widens nesting options and supports a greater variety of blank sizes. Confirm exact travel and minimum distance in the ANCHU spec sheet.
Backgauge accuracy (example): up to ±0.004" (±0.1 mm)
Representative repeatability under normal conditions with proper calibration. Final guaranteed values depend on backgauge design, feedback hardware, and installation quality.
Table height (example): ≈ 30–33" (760–840 mm)
Height from floor to table surface, affecting ergonomics, loading method, and integration with conveyors or material handling equipment.
Machine weight (example): ≈ 10,000–20,000 lb
Typical weight range for a heavy-duty 1/4" × 10' shear. Floor loading and foundation requirements must be verified against the machine drawing and the facility’s structural data.
Important: All “example” values are indicative and not guaranteed for every configuration. Use the official ANCHU quotation, certified spec sheet, and installation drawing for engineering calculations and safety decisions.
Cutting performance & material guidelines
The 1/4" × 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, and blade condition.
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 a fraction of tensile strength (e.g., ~0.6 × Rm). Engineers should use material datasheets and apply an appropriate safety factor to remain below the machine’s rated capacity, especially for continuous production.
Illustrative material guidelines
| Material | Relative to 1/4" rating | Typical recommendation* |
|---|---|---|
| Mild steel (baseline) | Reference case | Up to 1/4" at full 10' as per rating, considering tensile strength and duty cycle |
| Stainless steel | Higher strength than mild | Reduce allowable thickness and/or cut length; verify with ANCHU engineering |
| High-strength low-alloy (HSLA) | Significantly higher strength | Consider thinner material, shorter cuts, or a higher-capacity shear |
| Aluminum | Lower strength | 1/4" is generally conservative on force; focus on blade clearance and support to control burr and edge deformation |
*Guidelines only. Actual limits must be checked against the official ANCHU capacity charts and your specific material properties.
What this means in practice
- The machine is a “workhorse” for mild steel up to 1/4" and thinner materials at higher throughput.
- Higher-strength materials require derating; thickness alone is not a sufficient selection criterion.
- Proper blade clearance and rake settings are essential to control burr, twist, and edge quality.
- For continuous heavy-duty cutting near the limit, duty cycle and blade maintenance schedules become critical to reliability.
Mechanical design & cutting geometry
The ANCHU 1/4" × 10' shear combines a rigid frame, guided blade beam, and tuned cutting geometry to deliver straight cuts and predictable edge quality for day-to-day fabrication work.
- Welded monolithic frame: Engineered to distribute cutting loads and minimize deflection, maintaining squareness and parallelism over time.
- Guided upper blade beam: Ensures near-vertical motion with controlled rake angle for consistent cutting conditions across the width.
- Rake angle control (where equipped): Allows tuning for different materials and strip widths, balancing cut force against twist and distortion.
- Blade clearance adjustment: Operators can adjust the gap to suit thickness and material, optimizing between burr, deformation, and blade wear.
- Hydraulic hold-downs: Clamp the sheet securely to prevent lifting and sliding, improving both safety and dimensional consistency.

Engineering notes & technical FAQ
This section addresses typical questions from engineers and technical buyers: how to interpret the 1/4" rating, what influences cut quality, and what information is needed for an engineering review.
How should I interpret the 1/4" mild steel rating?
The 1/4" rating is defined for mild steel of a specified tensile strength at full 10' cutting length. In practice:
- Higher-strength materials require more force, which may require derating thickness and/or length.
- Running at or near the rated limit continuously increases blade wear and stress on the hydraulic system.
- Duty cycle (how often you cut at maximum thickness) is as important as the peak rating.
What role do rake angle and blade clearance play?
Rake angle and blade clearance are key tuning variables that affect both cut quality and machine load:
- Lower rake: better squareness and less twist, but higher force and stress on the system.
- Higher rake: lower force, but potentially more twist on narrow strips.
- Correct clearance: balances burr, deformation, and blade life for each material and thickness.
- Incorrect clearance: too tight damages blades and material edges; 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.
- Plate camber, residual stress, and operator technique also affect final part length and squareness.
- For very tight tolerances, secondary processes (e.g., machining) may still be required.
How can I confirm that my materials are within safe limits?
To validate an application, compare required shear force and duty cycle to the machine’s rating:
- Use actual material properties (shear or tensile strength) in your calculations.
- Consider worst-case thickness tolerance and material strength variation.
- For near-limit applications or aggressive duty cycles, consult ANCHU engineering with full material data.
What information does ANCHU need for an engineering review?
To provide a precise yes/no and recommend settings, ANCHU typically requests:
- Material type(s), grade(s), thickness range, and mechanical properties (if available).
- Sheet/plate sizes, typical cut patterns, and part drawings or DXF files.
- Required tolerances for length, squareness, and edge quality.
- Expected production volumes, duty cycle (cuts per hour, shifts per day), and mix (high-mix vs repeat).
- Any special cleanliness or edge-quality requirements (e.g., for painting, welding, or sealing).
With this information, ANCHU can confirm whether a 1/4" × 10' shear is appropriate or if a different capacity or configuration is recommended for your workload.
