Guillotine shear scrap metals are designed for heavy-duty, large-volume scrap processing, making them the preferred choice for steel mills, large recycling facilities, and scrap processing centers.
Core Advantages
Unmatched Cutting Power
Available in shear forces ranging from 350 tons to 2,500 tons, our gantry shears handle the toughest materials including thick steel plates, I-beams, channel steel, angle steel, rails, round bars, steel pipes, structural steel scrap, and heavy metal bales. Cutting speeds reach 3–5 cycles per minute, delivering throughput of 20–110+ tons per hour depending on model and material.
Reinforced Integral Gantry Frame
The entire frame is constructed from thick high-strength carbon steel plates via full-penetration welding, followed by high-temperature stress annealing to eliminate internal welding stress. This prevents long-term heavy-load deformation, cracking, and frame distortion-ensuring decades of reliable service.
All internal contact surfaces of the feeding box are lined with NM500 high-hardness wear-resistant steel plates, which resist repeated impact and friction from scrap metal, extending service life and reducing frequent replacement costs.
Advanced PLC Automation
Gate type cutting machine Equipped with a multi-language PLC touch screen control system, the machine supports single-cycle and continuous operation modes with real-time monitoring.
FAQ
1: What materials can a guillotine shear cut?
A: Guillotine shears are designed primarily for sheet metal and plate - including mild steel, stainless steel, aluminum, copper, and their alloys. Cutting capacity depends on the tensile strength of the material (typically up to 200–500 N/mm²) .
2: How does a guillotine shear differ from a gantry shear?
A: A guillotine shear is a precision machine designed for accurate cutting of sheet metal and plate in fabrication settings. A gantry shear is a heavy-duty scrap processing machine for recycling applications, with larger feed boxes and higher cutting force but lower precision .
3: What is the typical cutting speed?
A: Hydraulic guillotine shears typically operate at 6–19 strokes per minute, depending on model and material thickness. Larger CNC models may run at lower speeds (4–10 strokes/min) due to heavier cutting capacity .
4: How thick of metal can a guillotine shear cut?
A: Models range from light-duty 6 mm thickness up to heavy-duty 40 mm thickness, with cutting widths from 2,500 mm to 12,000 mm depending on model .
5: What is the back gauge and why is it important?
A: The back gauge is an adjustable stop that positions the workpiece for repeatable cut lengths. CNC models offer programmable back gauge positioning with accuracy of ±0.10 mm . It is essential for batch cutting and consistent part production.
6: What are the maintenance requirements?
A: Regular inspection of hydraulic fluid levels, blade condition, and gap settings are recommended. Rectangular blades with four cutting edges offer extended service life - rotate or replace blades as needed. Leading manufacturers offer life-time support and service.
