Capabilities & typical applications
This 4-ft hydraulic guillotine shear is a versatile workhorse for blanking, panel trimming, and part prep in fabrication cells, maintenance shops, and contract manufacturing environments. It integrates easily upstream of press brakes, turret punches, laser cutters, and welding stations.
- Blanking and trimming of sheet metal for brackets, panels, enclosures, and cover plates.
- Preparation of blanks for bending, punching, notching, or laser cutting.
- Short-run, prototype, and engineering/maintenance work for OEMs and job shops.
- HVAC and ducting components, light structural parts, and general fabrication.
- Material prep in steel service centers and metal distribution for small-part orders.
- Educational labs or training cells needing an industrial-grade, compact NC shear.
E21S controller – simple, structured control
The E21S NC controller brings structure and repeatability to light-gauge blanking without the complexity of a full CNC system, making it an excellent match for 4-ft shear applications.
Core E21S functions
- Programmable backgauge: Enter the target cut length and let the backgauge move automatically.
- Job memory: Save common lengths and sequences for standard part families and kits.
- Stroke counter / batch tracking: Monitor cuts per job for QC and basic production reporting.
- Single and automatic stroke modes: Switch between one-off cuts and continuous cycles for batch runs.
- Clear display: Shows backgauge position, program data, and operating mode at a glance.
Benefits for operators & supervisors
- Short learning curve for operators moving up from manual shears or stomp shears.
- Reduces errors from manual measuring and marking on light-gauge sheet.
- Improves consistency of blank size and cutting sequences across multiple shifts.
- Well-suited to high-mix/low-volume environments where jobs are stored, recalled, and fine-tuned.
Mechanical design & blade system
Even at 4 ft and 1/8" capacity, cut quality depends on a stable frame, good blade support, and proper gap settings. The Umprotech 0.125" × 4 ft shear is engineered to support clean, straight cuts on light-gauge material.
Frame & beam
- Welded steel frame designed to resist twist and deflection during cutting.
- Guillotine-style upper beam guided on precision surfaces for accurate blade parallelism.
- Compact mechanical layout that still provides industrial-grade stiffness for light-gauge work.
Blades & blade gap
- Upper and lower blades suitable for mild steel, stainless, and aluminum within the rated capacity.
- Multiple usable edges (depending on blade design) to extend time between re-sharpening.
- Adjustable blade gap to match thickness and material type, helping minimize burr and edge draw.
- Recommended to set a smaller gap for thin material and stainless, and slightly larger gaps for softer alloys like aluminum.
Sheet support, squaring & handling
Good sheet support and alignment are critical to achieving repeatable results, even on 1/8" material. The 4-ft shear includes support features that simplify one-person operation.
- Front support arms assist with aligning small panels and 4 ft blanks, reducing operator fatigue.
- Precision squaring arm with scale helps ensure accurate first cuts and square blanks.
- Shadow line or LED cut indicator gives a visual reference of the cutting line for quick alignment.
- Optional front stops or extended supports can speed repetitive length cutting on production jobs.
Safety features
Safety is integral to the 0.125" × 4 ft shear, especially in smaller shops where operators may run multiple machines.
- Fixed and interlocked guarding around key moving components and rear machine areas.
- Hydraulic hold-downs clamp the sheet along the cutting line to reduce movement or kick-up.
- Foot pedal actuation with protective guard for hands-free cutting and safe operating posture.
- Emergency stop pushbuttons positioned at or near the operator station.
- Options for integration into cell-level safety systems (fencing, light curtains, interlocks) depending on site requirements.
Final compliance with OSHA and other applicable standards depends on the specific installation, risk assessment, and any additional guarding and procedures implemented at the customer site.
Budgetary pricing
For planning and capex budgeting, the Umprotech Hydraulic Guillotine Shear — 0.125" × 4 ft, E21S is positioned as an entry-level NC production shear for light-gauge work, with industrial build quality and digital control.
Final pricing depends on:

FAQ – Umprotech Hydraulic Guillotine Shear 0.125" × 4 ft
What is the maximum cutting capacity?
This model is designed for a maximum cutting capacity of 0.125" (1/8") in typical mild steel within manufacturer-specified parameters. Capacity for stainless and aluminum depends on grade, hardness, and setup and should be confirmed for critical jobs.
Can it cut stainless steel and aluminum?
Yes. The shear can process mild steel, stainless steel, and aluminum within the rated 1/8" capacity. For best performance, use appropriate blade materials and blade gap settings for each material type.
Is this machine suitable for production or just prototyping?
The 0.125" × 4 ft shear is designed for both daily production and prototyping. Its E21S backgauge and job memory make it suitable for repeat orders, while the compact size is ideal for R&D and short-run work.
What kind of power does it require?
The machine is typically configured for three-phase industrial power. Exact voltage and frequency options (e.g., 230/460 V, 60 Hz) are confirmed at quotation to match your facility.
How difficult is it for operators to learn?
Operators familiar with manual shears or basic NC equipment typically adapt quickly. The E21S interface is straightforward, with only a small set of key functions needed for daily work (length entry, quantity, start).
Can this shear be integrated into a cell with a press brake or laser?
Yes. Many users position the 4-ft shear as a blank-prep station feeding press brakes, lasers, punches, or welding cells. Material flow and safety zoning can be reviewed during layout planning.
Glossary of key terms (for non-specialists)
- Guillotine shear – a shear where a straight upper blade moves vertically past a fixed lower blade to cut sheet.
- Backgauge – a movable stop that sets the cut length by positioning the trailing edge of the sheet.
- Hold-downs – hydraulic devices that clamp the sheet along the cutting line during the cut.
- Blade gap – the controlled distance between upper and lower blades, adjusted for thickness and material.
- Rake angle – the angle of the upper blade relative to the lower blade, influencing tonnage and cut quality.
- NC controller (E21S) – a numerical control unit that manages backgauge and shearing functions; simpler than full CNC, ideal for standard blanking work.
- FOB – “Free On Board”; price at the manufacturer’s plant, excluding freight, duties, taxes, and local installation costs (used in capex planning).
